Gold, District Summary. 116 INTRODUCTION. 17 In the following pages I have endeavored to describe, as concisely as possible, the mineral resources of Nova Scotia. It will be seen that this Province holds in juxtaposition coal, iron and gold — a boon nature has conferred on few countries. The import- ance of this appears more fully when it is remembered that no other Province of the Dominion is similarly favored. The developmMit of our iron ores and coal must form an important page in our future history. Indications of the presence of valuable ores of copper have been discovered, although as yet they are almost untested. Among the minerals that have been worked and present themselves over large tracts of country, permitting a greatly increased out-put, may be mentioned the ores of Manganese, Gypsum, and Barytes ; Ochres, Brine, Marble, etc. Our deposits of what may be termed domestic minerals, such as Gypsum, Limestone, Building-stones, Clays, etc., are of unlimited extent, and good quality. In the absence of geological surveys, embracing the whole of the Province, it would be premature to venture beyond a bare reference to the districts likely to contain valuable minerals. It may, however, be remarked that I am able to give, from authentic sources, the extent of our coal fields. The area of the gold districts has been estimated at about 3,000 square miles. The iron ores of the Province are as yet known only in isolated localities, the total extent of which can hardly be estimated. When, however, it is considered that the ore properties • •• vm. of the only two companies who have turned their attention to the •ubject cover 56 and 30 square miles, without monopolising their re- spective districts, the extent cf the deposits wUl be understood. Thei being comparatively no demand for iron ores, but little search has been made ; should enquiries be raised, doubtless many new deposits would be found. The occurrence of " Laurentian " strata in the Province leads to the hope that the valuable minerals characterising them in Ontario and Quebec may be found here also. The information that I have been able to collect will show that we possess the materials required for building up large mining and manu- facturing industries. As this knowledge gains ground, capitalists and practical men will perceive the advantages offered to the miner by the Nova Scotia Government, and the natural assistance afforded by our position as the nearest of England's colonies and the future manu- facturing Province of the Dominion. In this Union the position to be assumed by Nova Scotia is ap- parently that of the workshop, in which our own and imported raw materials may be elaborated for the agricultural lands of the West, which will send us food in return- for the products of our labor. GEOLOGY OF NOVA SCOTIA. I give the following outline of the Geology of Nova Scotia, as nerving to indicate, in a rough manner, the extent and ages of the strata, which at one point present to the farmer soils well adapted to recompense his labors, and at another hold the treasures which excite the cupidity of the miner. The valley of the Annapolis River and the north shore of the Basin of Minas are occupied by measures of the Triassic age. They are not known to contain any minerals of economic value, and are inteiesting ■chiefly in connection with the trap-dykes which form a prominent feature in the Bay of Fandy landscape, and contain many curious and beautiful minerals. The Carboniferous measures next claim attention. These strata are aubdivided, by Dr. Dawson and others, into five groups. Ist. The Upper Coal Measures, composed of red and gray sand- atones, marls and shales. In this series coal seams are frequently met, as at Merigomish, Pictou, Wallace, etc., not however, large enough to allow profitable workings to be carried on. The Upper Coal Measures are met in the centre of the Cumberkr^d coal field, in Colchester and in Pictou Counties. t 2nd. The True Coal Measures. These strata contain all the workable seams at present known in this Province, and have been care- fully surveyed by the officers of the Dominion Geological Survey. They are met in Cumberland, Pictou, Antigonish, Cape Breton, Richmond, Victoria and Inverness Counties. Outliers of those strata are believed to exist in Kings, Digby and Hants Counties, but their age has not yet been settled. The thickness of this formation has been considered by Dr. Dawson to Average 4,000 feet. 3rd. The Millstone Grit occurs at the base of the coal measures, and is particularly developed in Cumberland and Cape Breton Counties. It yields in the former county valuable beds of grindstones, etc., but no- where, so far as I am aware, does it contain any seams of coal. Hi 4th. The Lower Carboniferous Marine Formation. This is one of the most valuable of the rocks series found in the Province. Its detrition furnishes an excellent soil, and the beds of limestone and gypsum which abound in it provide unlimited supplies of two indispensible minerals. It occupies large tracts in Hants and Colchester Counties, and is extensively developed in Cumberland, Pictou, Antigonish and Kings Counties, and in all parts of Cape Breton. The greater portion of the best farming land of the Province is underlaid by this set of rocks. 5th. The Lower Coal Measures. These strata are met at Horton, and in Hants and Cape^ Breton Counties. They are distinguished by an abundance of blaok bituminous and carbonaceous shales, so that they are often considered to be coal-bearing. As yet, however, no workable coal beds have been found in them. The extent of the carboniferous measures in Nova Scotia may be estimated at 5,000 square miles. As yet the various subdivisions have not all been mapped out, attention having hitherto been directed to the coal-producing districts. Devonian. — The iron ore bearing strata, of the south side of the Annapolis Valley, have been described by Dr. Dawson as Devonian, but his conclusions arc disputed by Dr. Honeyman, the Provincial Geologist, who is inclined to consider them of much greater age. The labors of the Geological Survey have indicated extensive areas in Rich- mond and Cape Breton Counties, as being probably Devonian, but this opinion may be modified on more extended surveys. These strata, as met in Annapolis County, contain very valuable beds of magnetic and hematite iron ores, which are known to extend over a considerable range of country. Upper Silurian. — Our knowledge of the extent of these measures ia not yet complete. In this connection Dr. Honeyman has rendered valuable service by his labors at Arisaig. From this point, which may be considered the key of the Silurian geology of Nova Scotia, he has traced them through Pictou, Cumberland and Kings Counties, lliese strata hold valuable deposits of bedded iron ores, and are in this respect typically developed in Pictou County. Lower Silurian. — These measures occupy large districts at several points in Cape Breton and Nova Scotia, but no systematic surveys have AS yet defined their limits. Succeeding these strata come a vast area |e of fcion sum lible ies, land pion of ton, an ley ihle XI. •f Btrata considered to embrace all the o' ler measures typically de Teloped in Canada proper. Tbe labors of Dr. Honeyman, and of Mr, H. Fletcher, of the Geological Survey, have shoi^Ti large areas of Laurentian strata, with limestones and iron ores similar to those characterising the Laurentian of Ontario and Quebec. The age of the strata holding the gold-bearing lodes of the Atlantic coast has not yet been settled. Including their associated granites, they are estimated to cover 7,500 square milca of the Province. The re- mau^ng 6,000 square miles are considered as occupied by Silurian and Devonian and Triassic Strata. Dr. Dawson's classical work on Acadian Geology gives full details of the distribution of the various rock systems. The proceedings of the Nova Scotia Institute of Natural Science contain many valuable papers by Dr. Honeyman, illustrating the extent and divisions of the ^Murian system. The reports of the Canadian Geological Survey since the year 1869 contain valuable reports on our coal and iron fields, as well as on the structural geology of Gape Breton. From the above works a correct idea can be gathered of Nova Scotia geology, as worked out up to the present date chiefly by the labors of unaided individuals. When it is considered how little really is known of the ages, distribution and economic values of our pi'e-carboniferous strata, the importance and even necessity of a complete survey of the Province becomes apparent. Further allusions to this will be found in this report, but it may be remarked that the direct benefits accruing from such a survey would many tines outweigh the expense of its. execution. THE MINES AND MINERAL LANDS OF ITO'V^.A. SOOTI.A.. CHAPTER I. COAL. — SHALES. — PETROLEUM. The Coal Fields of Nova Scotia. — The history of our coal trade is so admirably treated by Mr. Richard Brown, that I need not recapitulat(* facts within the memory of most people ; but may proceed at once to lay before you all the information that I have been able to collect bearing on the extent of our coal deposits, the nature of the seams, and the uses to which they are applicable. Nova Scotia Coal belongs entirely to the bituminous division of Dana, no anthracite having been met as yet.- It may be subdivided into coking, cherry or free-buniing, and cannel coal. I In the following description the various coal-producing districts will be arranged in order from the eastern extremity of the Province — the thickness of the beds, their composition, names of chief mines, and other infoniiation being submitted. It may be premised that the productive coal measures of Nova Scotia l)elong to the same horizon in the Greological sequence as those of England and the United States, and present many points of intimate connection in fossil remains, and in the associated strata. Dr. Dawson's "Acadian Geology" gives very full accounts of the mode of formation, and of the flora of our coal measures, any notice of which would, although very interesting, be foreign to the scope of this report. NOTA SCOTIA MINES CAPE BRETON m iri Sydney Goal Field. — This district occupies the uoith-east corner of Cape Breton, and a small portion of Victoria, Counties. Mr. Robb, in his reports (Geo. Sur. 1 87 2-3\ estimates the extent of the coal district at 200 square miles, its dime^.isions being alx)ut 32 miles from the north- west to south-east, and 6 in width. This coal field forms the area of an extensive basin, the greater part of which is hidden beneath the Atlantic, fortunately, howjver, nearly all of the seams" can be followed in their subaqueous extension, and rights have been taken out co\'ering about 100 square miles of the su'o-marine coal. Mr. Poole, in his report to the Commissioner of Mines for the year 1377, says: " Assuming for the present a contour line three miles from sliore to be the boundary of profitable working, and four thousand feet the availably depth, and that no seam under three feet will be worked, then taking into consideration the minimum cover of solid measures required by our present law, the reduction to be made on account of known anticliuals, and the average thickness of tlie seams along their shore crops, the sub-marine coal field of Cape Breton, from Mira Bay to Cape Dauphin, will yield 1,866,000,000 tons. This estimate assumes that after allowing one fourteenth for unavoid- able loss a»id waste in working, 1,400 tons may be obtamed from each foot acre, as was assumed in the enquiry by the Royal Commission to ascertain the quantity of coal remaining unwrought in Great Britain,'" The estiihates of Mr. Brown and othei-s make the total of available coal rather larger ; but enough has been said to show that the sub-marine areas form an important addition to the visible coal field.* The seams appear on the shore, sweep inland, and again enter the ocean, forming- segments of irregular ellipses, whose centres are miles out at sea. This ' peculiar formation is repeated at Cow Bay, Glace Bay, Lingan, Sydney, and Campbelltown, and presents a number of almoF.t independent basins, the correlation of whose seams was long a puzzle to those engaged in developing the districts. After a careful survey, extending over a number of years, Mr. H. Fletcher, of the Geo. Sur., has demonstrated the equivalence of several of the seams of this district fonnerly regarded as distinct. The following table shows, in a condensed form, the views he arrived at, which, although differing from the arrangements proposed by other Geologists, may be regarded as correct. » For further information, gee " Sub-marine Coal of Cape Breton," bv E, Oiipin.

Tlie exceptional freedom from faults which chai-acterises this coal field has been strongly dwelt upon by all who have been engaged in exploring it. Prof. Lesley, in reporting on the Little Glace Bay district, says : " The water level lines of the beds are now seen to be parallel, and the whole country wonderfully level, and free from faults." This remark applies equally to the other districts, and adds materially to the confidence with which mining operations are begun. I have not given the thickness of the seams and associated strata in each district, as the dimensions of the Lingan section answer fairly for the rest. There are other seams found underlying these, and varying in thickness from two to eight feet; but I will not notice them further than to say that the fossils associated with some of the beds would indicate an extension of the productive or true coal measures much further to the westward than was generally believed to be the case. Taking the seams as given in the table in descending order, we have first to notice seam A, which has not yet been worked. Although the land area of this seam is small, it is believed that it will >)e found accessible under the sea for a long distance. The Lloyd's Cove seam was opened by the General Mining Association in their Sydney area, some years ago, and workings were extended over about 18 acres, but it being found that the Main seam could meet all demands, it was abandoned. The Hub seam was opened and extensively worked by the Little Glace Bay Co. some years ago. The land area of this seam is about 150 s ^^™^^^ NOVA SCOTIA MINES acres, 60 of which hae been partly worked out, leaving a large amount of good coal ; but all operations are now abandoned. The accessible sea area of this seam is estimated at 2,500 acres, yielding 35 millions of tons of coal. The coal from this seam is well adapted for gas making, the quantity per ton varying from 9,500 to 10,000 cubic feet of 15 candle power. The residual coke is of excellent quality. From an official report on the coal from this seam and the underlying or Harbor bed worked by the same Company, made to the Admiralty, it appears that the former contains 80"9, and the latter 83'5 per cent, of Carbon, and are theoretically equal to Welsh coal, which is bonie out by practical tests. Both of the coals wei-e found to light quickly, make steam fast, and to give a moderate amount of clinker and ash, the only drawback that was mentioned being the fad that they yielded a considerable amount of smoke. From trials that have been made since, in England and the United States, it has been she-wn that, with proper draft and furnace arrangements, the bituminous coals of the class under consideration can readily Im burnt, not only without producing smoke, but with a correspondingly increased evaporative power. The slack coal from the Hub seam was made into coke to a small extent some years ago. The quality was said to be excellent, and to have but little Sulphur ; but I am not aware of any analysis having been made. The next seam on the list has been extensively worked by the Block House, Little Glace Bay, International, Victoria, and Sydney Collieries. The coal from the Block House Mine has yielded at the New York and Boston gas-works 10,316 cubic feet of 16| candle gas, and 1,460 lbs. of coke ; and large quantities of it have been sold for that purpose in these markets. It has also proved a capital steam coal, and when tried on board H. M. S. Gannet, was found to raise steam fifteen minutes quicker than any other coal that had been supplied to the ship. When mixed with twice its weight of Tillery Elled Welsh Coal, a saving of 12 per cent, over the Welsh coal alone, was reported. The per-centage of ash and clinker was very small. At the works of the Little Glace Bay Co. this seam has recently been opened at a lower level, and the quality of the coal found to AND MINERAL LANDS. improve. The following are the Gas values of the coal, as det<»rnuned during the past year : Montreal New Citi/ das Co. Gas, cubic ft., per ton . . . .^. 9,268 Candle Power 15 Coke (good) bus 40 Halifax Gas Co. Gas, cubic ft., per ton 9,700 Candle Power 14'75 Coke (very good) bus .^9 I have already spoken of the fitness of this coal for use in the English Navy, and lemark here that the results would be found higher from the coal at present mined. At the International Mine, on the South side of Lingan Bay, this seam differs little from its characteristics observable in the Glace Bay Stirling Pit. The quality of the coal is very good, being compact and free from shale. It has been used chiefly for gas in New York ; and has been successfully introduced for the same purpose into the Montreal and Ottawa markets. It has yielded 10,000 cubic feet of gas of 16 candle power, and 1,470 fcs. of good coke to the ton. It has also been satisfactorily used for a steam coal, and certified equal to best West Hartley, the only drawl?ack being a clinker apt to adhere to the furnace bars. From trials made during 1879, and noticed in speaking of the Pictou coals, it appears that this coal is well adapted for locomotive work, and is highly recommended by those in charge of the tests. At the Victoria Mine the seam is more compact, and loses to some extent the bright, pitchy appearance it presents to the South. The coal is not recommended for gas making, but is found to be a capital steam and house fuel^ and has never been known to heat in cargo. It has not been tried for coke ; l»ut the slack finds sale for steam and blacksmiths' work. At the Sydney Mines of the General Mining Association, this seam has proved of excellent quality for steam and domestic use. The estimation it is held in for the latter purpose may be judged of by the fact that it retails in Halifax at a price 30 to 80 cts. higher per chaldron than any other Cape Breton coal. The following are the average results of four trials ol. its gas values at Halifax : Gas, cubic ft., per ton 8,200 Candle Power 8 Coke (good) fl)s 1,295 f) NOVA SCOTIA MINES It has been pronounced by the Engineers of the French Navy equal to the best Newcastle, for steam-raising, and has l)een extensively used by mail and other vessels for a number of years. The following is the result of a trial of this coal made by the American Government in 1841, and is, as far as I am aware, the only practical trial that has been made of the evaporative power of any of the Cape Breton coals : Moisture 3-13 Volatile Comb: Matter 23-81 Fixed Carbon 6757 Ash 5-49 Lbs. of water to one of coal, from 212° 7-90 Ash and Clinker, per cent. . . 6*00 Theoretical Evap, Power.. .. 9 25* The following analyses show the composition of this seam, as worked at the Collieries noticed above : COM POSITION, t ill Moisture Vol: Comb: Matter, Fast Coking Fixed Carbon " " Vol: Comb: Matter, Slow " Fixed Carbon, " " Ash •, Sulphur Specific Gravity Tneo: Evap: Power, Fast Coking '* " " Slow " Block HOUSR.

Although of good quality, they have hitherto been neglected in the presence of the larger seams, and may at this date be considered an impoi-taiit reserve. I regret that I am not in possession of any analyses or other positive information relating to these seams in the Southern part of the district, beyond the records of sinking pits and exploratory slopes, which agree in describing them as being suitable for steam and domestic use. The only opening in them is that made by Mr. Campbell, at Cape Dauphin, where the equivalent of the Black Rpck seam has been worked. At this point the seam is 4 ft. 6 in. thick," and finds a market in Halifax and other Provincial poi-ts as being adapted for house use. '* AH the evaporative powers, as given in this report, are calculated from Regnault'i formula. t Unless otherwise specified, the coal and ash analyses are by the writer, and taken from a paper on "Canadian Coals, their Composition and Uses," communicated by hira to the North of England Mining Institute, 1878. AND MINERAL LANDS. ml bed |aii il IJX) id The next Ream on the list is knovii as tlie McAulay, Phelan, and Lingan, and is worked by tho (Jowrifi, Ontario, Caledonia, Reserve, and Lingan Collieries. This \aluable Ijed has furnished a large amount of coal, and may be considered the typical .seam of the district. • At the (iowrie Ooliiery the seam is 5 ft. 2 in. thick. The product is used for steam and domestic purposes, and has been found adapted for iron working. From certificates given by engineers and masters of steamers, the coal is considered superior to all English coals, except the Welsh, for evaporative power. Its freedom from clinker, and low per- centage of ash, and the consequent absence of irijury to fire bars, are specially dwelt upon. In the retorts of the New York Gas Co., it yielded 9,000 cubic ft. of gas 'of 15 candle power, and 1,230 fcs. of good coke to the ton, and 2,100 cubic ft. were purified by one bushel of lime. At the Ontario and Caledonia Mines, this seean varies its character slightly, and becomes, although still a good gas coal, i-ather more free burning, and holds slightly above the ordinary per-centage of ash found in the Cape Breton coals. The Caledonia coal has been largely exported to the New England States for steam and gas purposes, and also for lime burning and domestic use. In 1878 it yielded, at the Montreal Gas-works, per ton of 2,000 lt)s., 8,900 cubic ft. of 14*25 candle power, and 36 bushels of fair coke. At the Reserve Mine it forms one of the handsomest of the Cape Breton coals, and is used chiefly for steam purposes. A conside/'able amount is sent to Newfoundland, where it is in demand for sealing steamers, whicli require a coal capable of raising steam rapidly. It has yielded, as a gas coal, 9,950 cubic ft. of 13-17 candle gas, and 1,500 1T)S. of coke per ton. 2,380 cubic ft. are purified by one bushel of lime. At Lingan this seam laid the foundation of the gas reputation of the Cape Breton coals in the United States. Large quantities were exported to New York and Boston for this purpose, but it shares the late depression. It is said to yield from 9,000 to 10,000 cubic ft. of 15^ candle power gas per ton. It has also been used to a considerable extent for house use, and should prove an excellent steam coal.

The coal from the openings at the Schooner Pond, Emery, and Collin.s' Collieries is also reported to be adapted for gas purposes, but I am not in possession of any detailed experiments.

It is, also, as Appears from the notices of certificates, equal to the coal furnished to the English Mercantile Navy, being considered as almost equal to Welsh steam coal, which may be rahked as the standard for comparison. The enonnous amount of available coal it contains may l>e estimated from the Geological Survey Report, which states that the seams now opened contain, ii *he areas leased for the purpose of working them, over 212,000,000 tons. This estimate does not include the coal in tlie seamH which are unopened in the land areas, in operation, nor the values of the seams on the leases which are at present awaiting a favorable opportunity for ours and breakwaters have Iteen made at Glace and Cow Bays, by several of the companies, while others ship at Sydney Harbour. The Oape Breton Coal Company have commenced sliipments at Louisburg, and it is to l)e hoped that this fine harlxjur will soon be '.'xtensively used as an all winter shipping place, r.ot only for the proprietors of the Cape Breton Company's Mines, but also for other con)panif»8. The cost of the coal, mined and put into oars, varies at the different colfleries '-oni 60 cents to $1.25; the transport and shipping, and interest on capital being different in each case. Surface lal)Ourers receive from 85ct8. o $1.00, mechanics $1. 10 to $1. 50 a day. The wages of the coal cutters, who are paid by contract, vary from $1.25 to $1.75 per working day. Provisions, lumber, land, etc., are easily and cheaply procured, and few countries offer better facilities for opening coal mines. INVERNESS. • lucentesH Coal Field. —From Cheticamp to Judique, on the Western sho/e of Cape Breton, there extends a narrow and broken line of productive measures, forming the edges of great basins of coal, which have long ago disappeared beneath the (Julf of St. Lawrence. At Chimney Corner, Prof. Hynd reported two groups of seams, nothing being known of the lower. The upper gave the following section : It. 111. "« Thin Seams 1 6 Strata ; 300 , Coal 3 Strata 88 Coal 5 Strata 200 Coal 3 6 The measures here form a sharp synclinal, about three quart^ers of a mile wide, giving an estimated land area of about 5 square miles; however, but little is yet known of the extent of the seams of the lower ^roup. III III i I I 1 ! i 12 NOVA SCOTIA MINES At Broad Cove, about 10 miles to the south-west, the following section of seams, contained in about 2000 feet of strata, is said to exist, and is given on Mr. A.Wright's authority. First Seam 2 feet. Second " 2 " Third '* 3 " McKiunon Brook. Fourth " 4 " " Fiftli " 12 " f Sixth " 7 " Seam now worked. Seventli " 4 " Big River. Eightli " 3 " Operations have been confined to the 7 foot seam, from which a few tons have been shipped to Monctou and Prince Edward Island. The extent of productive measures here is not yet positively known, but areas embracing about twenty square miles, believed to hold workable coal, have been secured by various parties. In the Geo. Sur. Rep. 1874, p. 183, it is stated: "Judging from appearance, the coal, which is of the bituminous kind, seems to be of excellent quality. From the manner in which it burns in a common fire, I should judge it to be peculiarly free from liability to produce dense black smoke." The coal has l)een satisfactorily Ijurnt for house and steam purposes. The district at present labors under the disad- vantage of having no proper shipping ground. It is proposed to remedy this by opening Mclsaac's Pond, about one mile distant, which operation, if successful, would provide good loading facilities, and a harbor of refuge for this section of the Island. Another of these small, but valuable, coal fields occui's at Mabou ; liere the outcrops of the following beds are repoi-ted, namely, a 4 foot bed, a 13 foot bed, about 20 feet above the first, a 7 foot seam 120 (1) feet higher, and a 5 foot seam. There are slso several other seams, the size and extent of which are unknown. The usual basin shape is presented here with an area somewlmt smaller than at Broad Cove. At Port Hood one seam only has l)een definitely tested, although the preseuce of several others has been proved. Here the strata run more nearly parallel with the shore, and extend along it about 2 miles. The seam opened has a thickness of 6 feet. Workings were pusheeen extensively worked at the Vale Colliery, and has proved well adapted for steam raising in marine and stationary, as well as locomotive, engines. The President of the Moisie Iron Works writes, that it is admirably adapted for iron making, as \he grates require cleaning only once a day. AND MINERAL LAUDS. ' 17 The Manager of the Richelieu and Ontario Navigation CJo. states that, " the coal makes no clinker, and is easy on the grates ; and lasts longer than Scotch. I consider it equal to Scotch coal in its results." The Q. M. O; «fe O. R. R. authorities find that, when mixed with Scotch coal, the results are higher than if the coals are burned separately. Nearer home the coal has been largely used on the Intercolonial Railway, and the steamers of the Allan Line. The upper group is represented on the western side of the East River by the small seams lying along the axis of the Albion synclinal, and not at present considered as occupying an area requiring extended notice. ^ The lower group, hidden in the Elastern district by the measures holding the seams just described, has been extensively worked to the west of the East River, and presents the following section : Ft.

Main Seam 34.7 Strata 148.0 Deep Seam 22.11 do 106.8 Third Seam 5.7 do ;..- 113.0 Purvis Seam 3.6 .... do .... • 130.0 Fleming Seam 3.3 .... do 4.3 McGregor Seam 12.0 .... do 211.9 Stellar Seam 5.0 •^ do 15.0 Seam A 11.0 do 187.6 Seam C 10.0 There are other underlying seams which, with seams A and C, have not yet been tested, and are known only as outcrops. The Main Seam has been worked for many yeai-s at the Albion Mines by the Halifax Coal Company and their predecessors. The Acadia Seam of Westville, operated by the Acadia, Intercolonial, and No\a Scotia Coal Cos., is considered to be, if not an extension, at any rate the equivalent, of the Main Seam. The general form of the Main Seam is that of an irregular synclinal, the north edge of which has been proved on the Mortroal and Picton area, opposite New Glasgow ; i;- ,. |, t ■ I'' ii 18 NOVA SCOTIA MINES * . while as yet all mining operations have been confined to the southern outcrop. The seam opened at Culton's Mill Pond,- to the south-east of the Intercolonial Colliery, is believed to represent the extreme southerly extension of the Main and other seams in that part of the district. The coal from this seam at the A.lbion Mines is well known as a very good steam coal ; and also yields a coke of good quality, which has been successfully used at the Londonderry blast furnaces. The folloA^g analysis is given, compared with Connelsville coke, which is considered the American standard for this class of fuel : Albion Minee.< Connelsville. t Moisture -96 52 Carbon 83-85 85-24 Sulphur -52 -69 Phosphoric Acid -01 -029 Ash 14-50 12.30 The coke is hard, resistant, and well provided with cell spaces. Large quantities of this coal were, some years ago, exported to the United States for gas making, and the following analyses of two samples from the north and south side of the Foord pit dip workings show that it still maintains its character in this respect : Analyses made at the London Gas Light and Coke Co's. Workt, 1879, gav^ 10,300 and 10,450 cubic ft. of 15 candle power gas, and 14 cwt. 2 qrs. of good coke per ton of 2,240 1)8. At the Works of the Pictou Gas Co., this coal yielded gas generally exceeding by one or two per cent, the legal illuminating power, which is fixed at sixteen candles, and proved very free from sulphur when tlje purifiers were attended to. Two samplee of coal from Pictou were tested at the American Navy trials in 1843. The coals must have been from the Albion Minee, working the Main and Deep seams, there being no others then op|ned ; but it is not stated which seam they represented.

I AND MINERAt LANDS. 19 At the Intercolonial Colliery the coal is of a similar character — yielding a merchantable coke, of which I regret I have no analysis ; and proving well adapted for steam raising, for which purj^se it has been extensively used on the Intercolonial Railway, and various steamers. It is also a good mill coal, and large quantities have been sent to Montreal for this purpose. From careful testa, it has been proved to evaporate 7'69 lbs. of water' from 212° F. for every pound of coal burnt.* From trials made on the Gulf Port steamer " Secret," and others, the ooal has received a very high character. The latest gas analysis that I have seen gives its yield at 7,000 cubic ft. of 15 candle power, with 34 bush, of good coke. It has also been extensively used as a house coal. At the Acadia Colliery the coal is of a rather more free burning character ; but it is on a par with the others as a good steam coal, under all conditions of use. From careful practical trials on a locomotive, it has been found capable of evaporating 7 24 lbs. of water from 212° F. for eveiy pound of coal burnt. It has been extensively used for steam purposes in Nova Scotia and elsewhere. It is also in good demand as a domestic fuel, and its sale for this purpose is increased by the care taken in its preparation. At the Nova Scotia Colliery, not at present working, the coal is very similar in adaptability, and has been extensively exported for Ifie same uses to the United States and Montreal.

The Stellar oil Coal, formerly worked by the same Company, is a very high cl&ss Cannel Coal. The Stellarite, varying in thickness from 6 to 24 inches, has above it 1 ft. 4 in. of fat bituminous coal, and is underlaid by about the same thickness of oil shale.

It is to be regretted that the vai'ious companies do not have a systematic trial made of the evaporative powers of their coals, as they would undoubtedly, when reduced to the standard test of pounds of water evaporated from 212" F. per pound of coal burnt, give results at least equal to those from any bituminous coals burned in ordinary practice. The Pictou Coal has been largely burnt on Atlantic and other S steamers, and in this connection its firmness and non-liability to break * up by handling, add materially to its value. Goals from this district afford a good, non-sulphurous coke, and possess the rare qualification of being adapted for use in blast furnaces in the raw state, and are well suited for mill work. The Pictou coal is well prepared in various dimensions for domestic purposes, and the nut size from the Vale and Acadia Collieries, and the Deep Seam of the Halifax Co., is found suitable for use in soft coal base burners. There are at present four companies working in this district. Their Collieries are large, and well equipped, and equal to an annual out-put of from 75,000 to 250,000 tons of coal. Details of the Collieries, their engines, styles of working, etc., will be found in the Reports of the Department of Mines, There are within the limits of the Coal Field several ^rge and Taluable undeveloped areas ; and in the event of an extension of trade, the out^put of the district could be very largely increased. N AND MINERAL LANDS. 28 18, No complete estimate has yet been made of the coal contents of thitt district, as there is so large a portion of it untested. An idea of the immense quantity of coal coiitained by the thick seams of the Pictou Goal Field in a limited space, may be gathered from the fact that the area of the Halifax Company is estimated to contain 67,365,000 tons of available coal, after making every deduction for faults, lost pillars , etc. The northern extension of this coal field is cut off at New Glasgow by a bed of conglomerate, believed to have been brought up by a fault from the upper part of the millstone grit. This is succeeded to the north, in the district between New Glasgow and Pictou, by the upper, non-productive carboniferous measures. It is the opinion of Dr. Dawson and others, that the true coal measures are beneath this covering of new strata. Attempts were made to prove this by a borehole some years ago, but the operation was not carried far enough to allow of a decision. The truth of the opinion, which ceiiiainly is based on good grounds, should be carefully tested. If the anticipations prove correct, an immense coal field would be opened up under and around Pictou Harbor, the value of which could scarcely be estimated. CUMBERLAND COAL FIELD. This importaiit County has only recently begun to take its place among the coal-producing districts. The first openings were made at the Joegins by the General Mining Association on two seams 4 and 6 feet thick. Operations have been conducted here for a number of years. The coal has been extensively sold in St. John and other Bay of Fundy ports, as a house and steam coal. The extension of these seams inland forms what is considered the northern edge of the coal field, and openings have been made at several points, on seams considered their equivalents. The identification of the seams, however, is not yet settled, as the continuity of the measures is broken by faults, and the beds themselves vary considerably. At the River Hebert, a five foot seam has been opened, holding two partings, 16 and 10 inches thick, of shale. At Maccan, only two seams have been found of workable size, the lower being 4 ft. 4 in. thick, and the upper, 2 ft. 4 in. At the Scotia and Cumberland properties, a seam is worked, which is by some supposed to represent a horizon lower than that containing M e 24 KOVA SCOTJA MINtt !: ' ;i1 I! iili' the seams already noticed, and has the following sevtion, measured in the new tunnel in the Chignecto Works, viz. : Ft.

Th(} most easterly opening in this district is known as the Styles Mine. The coal here is 8 feet thick, with a shaley parting of 5 inches in the centre. The coal is reported to be of good quality, and well adapted for house use. From its appearance, it should prove suitable f'"" gas making ; but I am not aware of any tests having been made. So far as 1 am aware, little or no work has been done to ascertain what number of seams exist in the coal measures in the eastern part of the northern edge of the Coal Field, operations having been confined to a few outcrops offering ready access to the coal beds noticed above. The southerly dip of the Joggins Coal measures reverses, and small seams of coal are said to occur about 20 miles to the south. As yet, however, there has been no exploratory work done to settle, even approximately, their line of outcrop. It is to be hoped that the labors of the Geological Survey will afford the necessary general information, which should precede, and not follow, the practical labors of the coal prospector, and that inducements will be held out sufficiently encouraging to warrant search for workable coal beds. From the shore to Springhill little is known of the geological conditions of the country. The presence of w^dods, depth of soil, and * small demand for coal, has prevented a search in a promising district, for a mineral yf comparatively «mall value at the present moment, in in view of the extensive deposits already opened.

I have already alluded to it, when speaking of the Pictou and Cumberland coal fields ; and would add that, although we now have apparently more coal than required for our immediate wants, the discovery of, coal in these districts, close to the water, would facilitate immensely our opportunities of supplying coal to the western parts of the Dominion. And any development of workable seams in the Shuben- acadie district to which Dr. Dawson has drawn attention, would, from its close proximity to Halifax, allow of a cheap all winter shipment of coal, and furnish supplier of fuel, at a moderate cost, to the mMiufacturers of Halifax. At many other localities discoveries of coal have been made ; but the seams hitherto have not been considered of economic value. Among tb^se may be mentioned the North River of Truro, and the Folly Moun ''1, where the opposing crops of a 20 inch seam, of fair quality, have been tested. " The outcrops or seams, varying from one to two feet in thickness, have been found at several places along the base of the Cobequids as far as Cape Chignecto. Indications of coal have also been observed in the coal measures band extending from Lower Stewiacke toward and along the Kennetcook River. These measures are not well exposed ; and I believe nothing definite is known of their value. The occurrence of coal in this central district would, however, be of so great importance to the Province, and to the main line of Railway, that the subject well merits a thorough investigation."* At Hifnter's Mounta,ui, near Baddeck, Loch Lomond, Salmon, and (iaspereaux Rivers, Neil's Cove, and many other localities in Cape Breton, the outcrops of small seams have beea found, in carboniferous measures underlying the productive strata ; but are not regarded, so far as explorations have been carried, as likely to prove valuable. Petroleum. — The great oil reservoirs of this continent belong ap- proximately to the Devonian and Lower Carboniferous measures. In this Province the latter system, wherever recognized, has been so much disturbed and metamoi phosed that its yield of oil is, perhapst problematical. Indications of oil have been observed at Cheverie, Hants Co., permeating the gypsum and limestone of that locality, and are l>elieved to have risen from underlying bituminous shales. * Dawion'g " Acadia Geology," p. 270. O AND MINERAL LANDS. 29 III At Lake Anslie, in Cape Breton, indications of oil have been observed in strata considered of the same age, and numerous attempts have been made to strike it by boreholes. Numerous practical oil men have pronounced the signs, etc., indica- tive of extensive deposits ; and a large expenditure is now being made, which will, it is to be hoped, prove successful.

The Atlantic coast of Nova Scotia, from Canso to Yarmouth, is occupied by a series of measures presenting a rough, undulatory surface,^ diversified by numerous lakes and rivers, and arms of the sea running far into the land. The width of this district varies from 10 to 40 miles, and its area may be approximated at 6,500 square miles. In this district are large belts of .rock, commonly called granite, the limits of which have not yet been defined ; but it is believed to form an irregular bend, extending in a curve from Sambro to Cape Sable, and to form another interrupted belt, running from Waverley to Cape Canso. These bands are estimated by Prof. Hynd to cover about one-half of the district described above. In the following description I have availed myself of all imformation, private and official, that I have had access to, and may mention, among: the reconnaisance reports, those of Messrs* Poole, Campbell, Sterry Hunt, Selwyn, Heatherington, and Dr. Dawson, Prof. Hynd's detailed surveys of several districts, made to the Government, the Report* of the Department of Mines, etc. Mr. Selwyn remarks that the Gold-bearing series in Nova Scotia closely resembles the Cambrian and Lingula flag series of North Walee., also auriferous. The lower members of both series, in both countries, con- sist of a succession of thick, bedded, greenish-gray, feldspathic grits and sandstones, or quartzites, with intercalated bands of shale ; and these are similiarly overlaid comformably by black, earthy pyritous slates and sandy beds. On the south-west shore measures occur, as near Yarmouth, apparently belonging to the Quebec Group. AND MINERAL LANDS. 31 Mr. Poole, ex-Inspector of Mines, who has had extensive opportuni- ties for observation, divides the former of Mr. Selwyn's divisions into two series, the lower consisting of slates and grits, crumpled, contorted, and cleaved transversely to the laniinee and holding lodes, not yet found productive. In the next series quartzites predominate, and productive lodes occur. These measures are all metamorphosed, and especially so at certain points, as at Cochran's Hill, Sherbrooke district, where the slates have become steatitic, or talcose shists with rutile, garnets, etc. This great series of strata has been thrown into well-defined east and west u.ndulations, and again disturbed by a transverse series of undula- tions. The elevated points of intersection of these forces having been denuded, the lodes of gold-bearing quartz occur as sets of irregular ellipses. Prof. Whitney notices a similar connection of Galifomian lodes, with eroded anticlinals ; and a corresponding arrangement has been observed in the Black Hills. The lodes present white, vitreous, opaque or milky quartz, difltering very much in color and structure, according to the varying conditions under which it is found. At Renfrew, it sometimes occurs crystal- lised, and showing banded vein structure, or holding pieces of slate, etc. The lodes contain, as accessory minerals, arsenides and sulphides of iron and lead, blende, copper pyrites, oxide of i»on, copper glance, molybdenite, native copper, sulphur, chlorite, feldspar, garnets, mica, calcite, felsite, etc. ; not, however, in quantities of economic importance. Some lodes are apparently destitute of mineral matter, and hold but traces of gold. These are usually white and massive, vitreous to gi'annular, and occur sometimes fifteen feet in thickness. The thinnest single lode worked is, perhaps, the Irving, at Mooseland, which varied iii thickness from one-eighth to one-quarter of an inch. A lode 20 inches thick is considered a large one. The gold occurs in the lodes in spots and bunches of the free metal, of every shape and size, up to 60 ounce nuggets. It is also present in the accompanying metals, as fine scales among their layers and crystals. I have not seen it reported in combination with Tellttrium in thja Province. It is stated to occur crystallised. Among some specimens Fifteen Mile Stream, I noticed one apparently a pseudomorph cfter a crystal of cubic pyrites one-fourth of an inch square. .) 32 NOVA SCOTIA MIKES liii ai I 'HI! ' '''i 'ifiii The precious metal is not confined to the lode ; fox* in both slate and quartzite walls, crevices have been found, holding gold, and but little quartz. Frequently where there are two or more lodes in slate, it is found profitable to crush the intervening slate also, which holds gol^ in laminae, and in the almost omnipresent mispeckel. The occurrence of gold in cross lodes and leadei's will be noticed further on. < The quartzite forming the hanging wall of some lodes has also T^een seen to hold fine gold close to the lode. The age of the beds holding the auriferous lodes of the Province is not yet determined. Geologically speaking, they remain, in spite of many ingenious speculations, an unknown land. At first they were regarded as middle or lower Silurian ; afterwards as Laurentian. At present, adopting the provisional divisions of the Geological Survey, they are considered of Cambi^ian age. The ages of these rocks, unfortunately, cannot be determined by the imperfect and ill-preserved fossils that have been found. Their mineral- ogical characteristics are not to be relied upon for such a classification, as the strata cannot be traced into, connection with any supposed counterparts on this continent. Their age cap be approximate only by a systematic survey, which would require to be carried over the whole district in question. Although the age of these measures and the associated crystalline rocks is an intei'esting question, and, in some respects, a matter of practical importance, the survey would serve other most necessary purposes, commending it to all who are in any way connected with gold mining. Our gold district^, as at present known, were the results of chance discoveries, and were generally^ found through boulders or exposures in brooks, etc. When it is considered that the v jrked area of many of the districts is very small, it strikes the mind of even the most casual observer that in the woods and swamps of the interior there mu^t be many auriferous districts yet unknown. A geological survey which will map out all the axes of the undulations, the faults and their effects, their relation to the granites, etc., would be a great boon to the intelli- gent miner. By such a survey, certain lines would be found to present places where auriferous lodes would occur ; for it is apparent that a general rule must apply to the production of similar districts over so extensive a I'ange of country. With such a map before him, the prospector could go at onco to places where his labours Avould liavo a chance of success ; and a systematic AMD MINERAL LANDS. 33 search would reveal many new districts. Our knowledge of the structure of the Gold Fields is lamentably deficient, and its elucidation would be considered a great aid to labor and capital ; and undoubtedly prove a source of increased revenue to the Province. The Dominion Survey lias not yet reached the Gold Fields ; although I believe it was intended, some ten years ago, that they should be mapped out. The Province has done nothing beyond publishing reports on several districts, made for the Department of Mines by Prof. Hynd. It is true that the Dominion Survey lias already given us a fair share of attention, when it is remembered that its appropriation for the enormous district extending from Cape Breton to Hudson's Bay and Vancouver's Island is no larger than that paid to the Geological Survey of the State of New York. But if it is found that they are unable to undertake it at present, I venture to suggest that a small annual grant might induce them to increase their staff in Nova Scotia. The survey would thus be made at the least expense to the Province, and be benefitted by the experience and resources of the Dominion department. The money granted would be repaid by the possession of the topographical maps of the district under consideration, which would necessarily form part of the field work. Such a survey would also prove another most important point, the neglect or non-trial of which has, it is to be feared, caused a permanent injury to many districts : That is, the question of the depth to which the lodes hold gold in paying quantity. Taking Tangier at the sea level, and Mount Uniacke 560 feet above the sea, we are ignorant at the present moment what relative line they mark in the downward extension of the lodes. The amount of denudation being unknown, it cannot be said which is the highest. It may be found that our Gold districts represent, as it were, steps in a ladder, whose length agrees with the estimated thickness of the auriferous series, some 3000 feet. If such is the case, then the question of the auriferous quality of our lodes in depth would be affirmatively proved in a most ;;atisfactory manner ; aud the information gained outweigh many times the cost of the survey. An important point in connection with the lodes is the question — are they beds or true veins 1 The for|[ier view has been advanced by Dr. Sterry Hunt, Prof. Hynd, and others, who consider them similar to the Virginia and North Carolina deposits, as described by Profs, Silliman and Emmons. vi if 34 v riA MINES ijitsr i! i! I iii! k J; ill 5 J! I Mr. Selwyn, the Dire* t the Dominion Geological Survey, who has had extensive experience in the Australian Gold Fields, considers them true veins ; his reasons, which are clearly and concisely expressed, are to be found in G. S. R, 1870-71, p. 264. This view is supported by Mr. Poole (Report Dept. of Mines, 1878), who gives copious notes from a close observation, extending over a number of years. His remarks are practical, and I give the following extract from the report, which is well worth perusal : " Mining operationa are not confined to the bedded leads, for rich streaks of paying quartz have been followfld in cross leads and in what are called " angling " leads. As a rule true cross leads of later age than the true leads are barren, or contain but a few pennyweights of gold. Their influence, or that rather of some so-called cross leads, on the productiveness of a regular lead, is often remarked on, but cross-courses of later date are not always dis- tinguished from contemporaneous connecting bands of quartz filling transverse fractures of the same age as the bedded leads. The effect of cross leads on the productiveness of regular leads is worthy of note. For instance, at the junction of a cross lead with the Belt lead at Montague, some rich spots gave as high as 40 ounces to the ton. " " In sections where slates predominate, and there are few alternating beds of quartzite, the leads are ahnost invariably barren, or so sparsely spotted as to be unprofitable to work." " Angling leads are met, which cross the quartzites abruptly, and the slates gradually, proving rich in various instances in one or the other of the containing rocks." " Sooner or later, in the working of the regular leads, inequalities char- acteristic of veins are met with. Late operations at Waverley, in the east end of the Union lead, have shown the quartz to cease, while the fracture continues ita regular course. The workings have also exposed a regular ' horse ' of quartzite, and in one part of the foct-wall a roll of compact quartz eight feet mde, which in parts yielded handsomely. From the roll a number of strings of gold-bearing quartz were found to ramify in all directions into the foot-wall of quartzite. One spot immediately below this roll gave 90 ounces from a lot of 5 tons ; other strings in the foot-wall yielded largely. At a fault in this lead, drussy cavities contained crystals of quarts, galena, calcite, and iron pyrites. To mention one other instance, the West Lake at Uniacke contained a pocket beneath a swell in the lead five feet wide, so rich hat one crushing of 13 tons yielded 234 ounces. ' ' There are yet other characters suggestive of true veins ; often there is a narrow band of slate next the lead, which is called ' gouge,' on account of the ease with which it is extracted with a thin, long pointed pick. Its fissile nature probably is due to disturbance at the time the lead was formed. Again, thin leads have been known to taper out, and what may be called their continuation to start in the side slate, JRid expand to the original thickness from beyond the termination of the quartz at first worked. " While many of the gold-bearing leads are regular and persistent for hundreds of feet, and lie parallel with wonderful uniformity, a careful follow- ▲KD MINERAL LANDS. S5 ing shows local troublee. Breaks and dislocations of the strata are not uncommon ; and while many undoubtedly are of later age, some appear to ba contemporaneous. " He adds, in conclusion : " The distinctive features of the gold leads of Nova Scotia are th«ir general conform^bility with the slate and quartzite beds and their regularity, suggesting that they are rather beds than veins. But there are characters that point to their being true veins in spite of these features, and they are the following. The roughness of the planes of contact between quartz and slate and quartzite ; the crushed state of the slate or gouge on some foot- walls ; l!he irregvdarity of their mineral contents ; the terminations of the leads ; the effects of contemporaiy dislocations ; and the influence of stringers and off- shoots on the richness of the leads. Characters that, singly or col- lectively, it would be difficult to account for, associated with a stratified deposit. " The experience of all the miners, both native and from Australia and the Western States, is united in calling the lodes true veins. Although it may not be difficult to show that most auriferous quartz deposits are of later date than the enclosing rock, it is seldom possible to determine exactly the period of their formation. In this T wince, however, the presence of Gold in a Lower Carboniferous Conglomerate at Gay's River, would show that some of the veins at least are of pre-Carboniferous age. On the other hand, there is no reason why other veins in the Province may not be even of Tertiary date, or immediately preceding the formation of the auriferous alluvions. This repeated or continuous formation of auriferous lodes has been noticed in other Countries. - ALLUVIAL GOLD. Alluvial gold mining has not been carried on in Nova Scotia in any degree commensurate \nth. the value of the auriferous deposits which are in a greater or less degree known to exist, and which, in all proba- bility, occur to a much larger extent than is generally supposed. An impression has arisen that the greater part of the gold districts of Nova Scotia, present nothing but rocky, denuded areas, without any, or at least very small, drift deposits. The contrary is, indeed, the case in some districts ; and numerous wide spread surfaces exist where alluvial gold mining cannot fail to be pursued with great profit, if sufficient capital is embarked in the enterprise. Drift deposits are found at Waverley, upwards of fifty feet deep ; and at Tangier similar deposits exi;.t, which have already yielded remarkable returns, and have been abandoned on account of want of meanH to cope with the influjr of water. 1 l ff w 36 'SOYA &COTtA MINES I, !' \m\ ii A moment's reflection will satisfy the most incredulous that, wheie rich Gold-bearing lodes are exposed near the surface, in the valleys adjacent to such rjxposures, or in crevices in the rocky surfaces, the gold from the denuded lodes must have accumulated by its gravity. When, however, the lodes occur at the summit of a hill or on its slope, much of the liberated gold will be found on the bed rock and in the crevices, or in the lowest stratum of drift, in the valley below, whether occupied by a lake, swamp, or by drift. It has been alleged that the greater part of the former auriferous drift of Nova Scotia has been carried by recent denuding action into the Atlantic, and now forms the sub-marine banks of the coast. I This has certainly no foundation, and Mr. Selwyn states, " I can confidently assert that bare rock surfaces are not more prevalent in the gold districts of Nova Scotia than they are in similar districts in Australia." It is incredible that in the latter country, the Gold-bearing veins should be invariably accompanied by rich alluvial deposits ; while in Nova Scotia the detrital deposits, which certainly occur under precisely similar conditions, should be almost as invariably unproductive. I do not believe in any such anomaly ; but think the whole secret of the matter lies in the fact, that they have never yet been sought for with that degree of enterprise, intelligence, and preseverance which the investigation demands. Tangier, Oldham, Sherbrooke, Waverley, Renfrew, and many other places, present all the conditions for alluvial diggings, both in the form of old channels and their re-worked condition. Having briefly noticed the lodes, their nature, contents and associated rocks, the various districts next claim attention. It would take up far too much room, were I to submit anything approaching a detailed account of each one, and such description would necessarily be imperfect; for during the last few years operations in many of them have been carried on chiefly by tributors in a very desultory manner. I will, with your permission, give the position of each district, and a notice of any peculiarities of the lodes, their contents, value, etc. Carribou. — This district is situated 6 miles south of the Musquodo- boit Biver, at Hamilton's Comer, about 36 miles from the Shubenftc^tdie Station, from^ which point a tri-weekly mail nms to the Mines. Work of a preparatory character was undertaken first in 1867, 1 believe, and AND MINERAL LANDS. 37 has been carried on in an iuterniittent manner ever since. Several of the lodes have paid well, as the North, Flat, Cross, and Hyde Lodes ; of which the Cross Lode, at one time, gave quartz carrying 20 oz. A lode on the Bushing Area was found to lie for some distance in a horizontal position, apparently in the summit of an anticlinal. In 1877, a lode, found on Area 629, Block 2, one foot thick, yielded, in 6 months, 1170 oz., from a stope of 40 feet, and within a depth of 120 feet, the shoot of rich quartz being vertical, and at the junction of a cross lode. Moose River. — This district lies about 7 miles west of Carribou, and is accessible by a road from Middle Musquodoboit ; and has only recently received attention. The surface is reported to carry Gold, but the attempts made to wash it, proved unsuccessful, it is reported, from improper construction of the flume. Several promising lodes and many rich boulders have been found; and it is stated that in Dec, 1879, Henry Archibald had discovered a lode yielding over two oz. to the ton. Fifteen Mile Stream. — This district lies on a tributary of the East River of Sheet Harbor, about 1 9 miles from the head of navigation. It is very inaccessible, there being no carriage-road to it. Explorations have been carried on here for several years, and have shown the presence of a large number of promising lodes ; and two crushers were built. Its isolation, and the expense oi getting supplies,. have retarded the opening of this district, which, however, is again receiving attention. Gatja River. — This district is an interesting one, although it has never occupied an important position as far as its yield of Gold is concerned. It is situated about 6 miles east of Shubenacadie Station, on a tributary of Gay's River. Here the gold slates are overlaid by flat beds of, carboniferous conglomerate, an ancient consolidated drift. The Gold occurs in grains and scales at the base of the conglomerate, and in backs in the^slates ; small auriferous lodes have also been observed in the slates. The modem drift overlying the conglomerate has also yielded Gold, derived from a similar source, or from the natural working over of the conglomerate. The mining has been done by levels, driven in the conglomerate at the junction of the two formations ; but no rule has yet been observed indicating the position of the Gold. • Lawrencetoum. — This district lies about 12 miles east of Halifax Harbor. In the early days of mining here, a considerable quantity of Gold was taken from rich boulders and washings. The chief vein on the Werner property was 8 inches thick, of bluish quartz, showing gold, blende and migpickel. The Capel Townsend property embraces several ■ 38 NOTA SOOTIA MIKLS |i|.,. m ! I! groaps of Gold-bearing veins ; that known as the Waddilow group includes thirteen. The quartz, generally enclosed in slates, is somewhat ferruginous, and contained copper pyrites, blende, and a little galena. Some of these lodes were reported to have yielded well. Operations, however, have been almost totally suspended, after large sums had been spent in preparatory work, mills and machinery. The mining that has been done of late years has Yjeen confined chiefly to Orookes' lode, tho first opened ; and it yielded well at the junction of cross veins. A large number of promising lodes are known here, and there is no reason why they should not be worked profitably ; and it is to l)e hoped that another and more successful start will soon be made. Montagu. — This district lies about 6 miles east of Dartmouth, near Lake Loon, and has maintained an average out-put for a number of years, greatly increased during 1870 and the three following years. The best known lodes are, perhaps, the Belt, Werner, St. Patrick, and Cross Veins. The Beit lode has been worked by 8e\'eral parties, and notably, by the Messrs. Lawson, who, in the five years ending with 1874, extracted about 10,000 ounces, with a handsome profit. The lode is enclosed in slate, separating it from quartzite, and varies in thickness from 4 to 20 incihes. The quartz is highly crystalline, and shows, besides Gold, iron and copper pyrites, and mispickel. The sesulphurets, according to Prof. Silliman, are most abundant near the imderlying slate, which also holds gold and mispickel in lumps, sometimes weighing 50 lbs. During the tenancy of the Messrs. Lawson, a plan was kept, showing the milling value of each parcel of quartz extracted. This plan, while showing how irregularly the Gold is distributed in the vein, also determines the extent and character of the Gold streak. The richest part of the lode at the surface was at the Main shaft ; in deptlvt trended to the westward. For many years, the presence of rich boulders in the surface cover of the eastern part of the district, caused the expenditure of much time and money in a search for the parent lode. In the Spring of 1879, Mr. G. Stuart, and his associates, found the vein, called from the colour of the f quartz, the Rose Lode. It vanes in thickness from 4 to 18 inches ; as yet the workings on it are limited, but enough has been done to show a very rich chimney, dipping westward, at an angle of 30". Up to the present date 292 tons have been crushed, yielding 1086 oz. The property has been purchased by American capitalists, who ▲ND MINERAL LANDS. 89 Jiave removed the steam mill, built by Mr. Lawson, and considered one of the V>e8t in the province, from the Belt Lode, to the nf w shaft, where it will also do duty as a pumping and winding engine. It is to be hoped that their success will draw attention to the district, and lead to fresh discoveries. During the past year, a lode close to the Symonds Rtill yielded well at the junction of numerous cross veins, and promises to become more valuable than even the Rose Lode. Waverley. — This difttrict lies about 3 miles east of Windsor Junction Station, on thfe Intercolonial Railway. It has been reported on by Prof. Hynd, in 1869, and a full description given, which is too long for re-production here. I am not aware of any developments since the date of his report, which are calculated to throw any fresh light on the structure of the district. In the year 1865, the returns gave a produce of 14,000 oz., but the annual out-put has since dwindled away to a few hundred ounces. Among the chief lodes that have been worked, may be mentioned the Tudor, Brodie, South, and Taylor veins. Large and extensive works were carried on by Mr. Burkner, the DeWolf Co., the Boston and other Companies, but they gradually ceased working, as the main leads became impoverished at depth, .und varying from 150 to 400 feet. Since that date, operations have been carried on chiefly by individuals and tributors, who have taken out blocks left by the previous workers, and extracted quan z from new lodes. Sonxe of these new veins have yielded fairly, as the United, American Hill, New South, the No. 6 Lode. The barrel quartz, in the eastern part of the field, attracted much curiosity at one time. Here the lodes follow the strata, as they bend over in an anticline. The corrugations generally present the form of wave-like undulations, rarely that of tight folds, and at one place, a little to the westward, one of the lodes presents a nearly horizontal sheet. The quartz is somewhat banded, and holds calcite, apparently of later date, filling fissures in the lode. This has been worked at intervals for a number of years, and is said to have averaged 12 dwts. to the ton. Oldham. — This Gold Field is situated 3 miles east of Enfield Station. Gold was discovered here in 1861, and since that date operations have been carried on, with occjisional periods of depression. The worked portion of the district is characterized by a valley, having a nearly «ast and west course, occupying the croAvn of a very sharp anticlinal fold, the axis of vrhirh is nearly parallel to the area lines. i ; 40 NOVA SCOTIA Mi ES 'i''% m From records obtained by Prof. Hynd, it appears tiiat in this district the pay streak dips east, generally at a low angle. Among the most noticiable lodes, are the Barrel, Ohio, Frankfort Ritchie, Hall, Britannia, etc. A large amount of gold was extracted in 1877, by Mr. Baker, from a lode on the easier-' urn of the measures* -the result of five months work being 1,280 oz On areas 101 to 105 the Blackie lode was worked for some time in search of the mispickel nodules, which v/ere found to carry gold up to 5 and 7 ozs., per ton. Messrs. Donaldson have worked extensively on the Britannia, Hall^ and othc'*' lodes, on the north side of the district. Mention has already been made of the "Angling Lodes," of which interesting examples occur here. The low angle of dip of the pay streak has probably been the cause of the comparatively shallow character of the workings carried on here, which proves an impediment to systematic mining. This is to be regi-etted, as preliminary labours carried on in common would have facilitated operations, and' the work, so far as it has been earned, proves that the district promises to be one of unusual richness. Renfrew. — This district lies about 7 miles west of Enfield Station, near ^iie -lorth end of Grand Lake. Work was begun here about the same time v>& at Oldham, and the returns show a steady increase to 7,904 oz., in 1867 ; and a decrease to but 3 ozs., in 1874 ; since that date there has been a slight improvement. Among the more prominent lodete may be named, the Preeper, Sims, North, South and Brook. The operations of the Ophir Company were systematically conducted for several years, and handsome profits realized, but workings, w^ere abandoned at a depth of 350 feet. Their returns during five years were 17,532 ozs., 13 dwt. 21 gr. from 21,012 tons of quartz. All the mining has hitherto been confined to the south side of the anticlinal ; the measures on the north side are generally covered by soil, and although rich boulders have been found, the parent lodes remain for future workers. The proximity of lower carboniferous measures and their position relative to the lodes, furnish, according to Prof. Hynd's report, favour- able conditions for the accumulation of alluvial gold. Sherhrooke. — Tins district lies about 38 miles by stage from Antigonish, on the Halifax and Cape Breton Railway, near the village M W AND MINERAL LANDS. 41 of Sherbrooke, on the St. Mary River, and ranks first in the list of the Provincial Gold Fields. Up to September, 1866, this district produced 19,101 ozs., at the rate of 1 oz., 16 dwt. to the ton. In the following year, 5,809 tons yielded 8,522 ounces of gold. The lodes and associated rocks present no features distinguishing them from those of other localities in the Province. Among the numerous operations, the Wellington may be mentioned. Here work has been carried on ever since the discovery of gold in the district. The Wellington, Dewar, and other veins have been mined to depths varying from 400 to 600 feet. The proprietors have conducted their operations with care and prudence, and received a good return. Between the years 1863 and 1869, they extracted 8,984 tons, which yielded 12,215 ozs., and similar results have since been obtained. On the adjoining Grapevine properties, favourable returns have been made for a number of years. Other properties yielded well, but are now chiefly let on tribute. Among those that have paid well during the past year may be mentioned the Dominion, worked by Messrs. Fraser «fe Bent, and the Wentworth, under lease to Mr. Hattie. A very large amount of work has been done by other parties in this district, and it appears, from the continual discovery of workable lodes, likely to afford equally encouraging results for a long time to come. At Cochran's Hill, in this District, a little work has been done in lodes running in slate belts, and also at the Crow's Nest, two miles to the westward. The strata here, as already mentioned, are highly metamorphosed. The yield, so far, per ton, has been low, from 4 to 8 dwts. ; but the cheapness of extraction has enabled work to be carried on at a profit. Isaac's Harbor. — This district, known officially as Stormont, lies east of Sherbrooke. For several years the returns gave an annual yield of about 1400 oz. ; but during the last few years the mines have remained almost entirely neglected. Promising lodes have been found in the surrounding country, but ^have not yet been thoroughly tested. No district in the Province has better promise for the future than the one now uudi&r consideration. The extent of mining that was carried on is very small, and limited to a few lodes. The Mulgrave lode yielded 11 ' Ji i'rl . ■ ! f' S' /:: ! * Wi 42 NOVA SCOTIA MINES ji-i M ,1 1:1 ■;'l' i'l . ■ !:r from two areas in 1863-4, 621 tons of quartz, giving 1897 ounces of Gold; and the little work done since has frequently jdelded equally well. Wine Harbor. — This district lies on the coast, about 4 miles east of the mouth of St. Mary's River, and 12 miles from Sherbrooke. Here the auriferous quartz lodes «"*e met with, over a belt nearly a mile from north to south, and are in thick bedded quartzites, generally associated with thin layers of finely laminated, bluish slate, which facilitates mining. This district also shows, in its returns, the same falling off from the best year, 1864, when 4,033 ounces were obtained. Work has been confined chiefly to the ground owned by the Eldorado Company, where it has been continued by tributors since the proprietors ceased operations. The property of the Provincial Company has frequently yielded good quartz, the Caledonia Company having mined in six months $200,000 of Gold. The Hattie lode has also yielded good returns to those who have worked it. Tangier. — This district lies on the Atlantic shore, about fifty miles east of Halifax, from which town it can be reached by a tri- weekly mail, and is well known as the earliest opened. In the eastern part of the district, at Strawberry Hill, work has been pursued for a number of years, chiefly on lodes, known as the Dunbrack and Forrest, and others associated. The strata and the lodes are cut by a granitoid (1) dyke, about 15 feet wide, which can be traced for several miles in a south- west direction. It does not appear to affect the contents of the lodes in any way, nor to have shifted them. A number of lodes extending to the Tangier River, have been worked at various times ; among them may be mentioned the Feld, Leary, Nigger, etc., which have yielded fair returns in the moderate depth they have been worked to. A considerable quantity of gold was found in the alluvion at one place in this district, and a pond called Copper Lake was partially drained. Prof. Silliman states that a layer of tough clay and glacial drift was found underneath the mud and vegetable matter, and everywhere in the under clay small unrounded nuggets were found. The work of washing was, however, abandoned, as the drainage was not carried deep enough to allow its proper application. 1 ▲ND MINERAL LANDS. 43 Mount Uniacke. — This Gold Field lies about 3 miles from Mount Uniacke Station, on the Windsor Railway. A large number of lodes have been exposed over an area having a breadth of about one and a half miles, and a length, it is said, of six miles. The veins are similar to those of other districts, and enclosed in quartzite, frequently with linings of slate. Their thickness varies from one inch to several feet, and the large veins are sometimes divided into layers by interlaminations of slate. "The crystalline quartz, soinetimes milky-white, sometimes bluish, the latter being often laminated, fills the greater part of the lodes, and generally the widest ; while arsenical iron pyrites, or mispickel, is, at the outcrop, the mineral of the narrower lodes. Certain quartz lodes appear to the sight almost entirely destitute of foreign matter, while others contain metaUic sulphides, such as cubical iron-pyrites, often decomposed, mispickel, and, sometimes, blende, galena, and copper pyrites. I have observed in all the selvages of s »me lodes, a blackish earthy subs' ance which appeared to me to be the oxide of manganese. " A great irregularity of formation and of structure characterises generally the lodes in the area under review. One sees lodes hardly impregnated witn arsenical iron-pyrites at the outcrop, in narrqwing in depth, become converted into veinlets of pure mispickel. Such lodes measuring several inches at their outcrop, are reduced to a mere thread at a few feet in depth, while others are subject to successive and sudden contractions and swellings. But the most extraordinary case of irregularity, is that of the^lodes which assume curiously twisted shapes by branching sometimes to the north, sometimes to the south. The constancy of formation and structure, that is to say, the regularity of the deposits, has been, so far, the rarest case with the lodes in these areas ; but experience has demonstrated in many localities, that the disorders which I have described, often disappear at a certain depth." — Rep. H. Y. Hynd. The report, from which the above extract is taken, contains interesting information about the number, position and assays of the lodes, and their relation to the geological features of the surrounding country. Among other districts, may be mentioned the Ovens in Lunenburg County, where alluvial washings were carried on for a short time ; Gold River, Yarmouth, Stewiacke, Chezzetcook, Ship Harbor, Harrigan Cove, Moose Head, Ecum Secum, etc. Gold has also been reported fronii^he Cobequid and South Mountains. In Cape Breton, the Middle River, Baddeck, was, some years ago, made a Gold district, under the name of Wagamatcook, but no profitable lodes have been found, although the slates occasionally yield scales of Gold, and it occurs everywhere in the beds of the streams. Mr. Campbell, in his report, in 1863, gives an interesting account of his examination of th« northern part of Cape Breton, and reported alluvial Gold in the sands of many of the brooks. Mi I- .1 44 NOVA SCOTIA MINES i m 'nff '!*-, ■I K 1. . The initiation of Gold mining in the Province, was by men but little skilled in mining ; their operations consisted in trenches and shallow workings. The comjjanies that next succeeded, opened veins on a large scale, built mills, etc., but in too many cases made no provision for those periods, common to the history of all fissure veins, when much expensive dead work is required. At present, the mining is chiefly in the hands of men of comparatively smalJ means, who, however, have gained practical experience, and their economy and oare have frequently yielded them handsome returns. Every visitor to the various districts, is struck by the want of system shown in the early workings. Long trenches following the outcrops, shallow pits, and lodes stoped to grass, all show a neglect of fundamental principles, costing succeedin', miners much money. This state of affairs, which is common to the ineption of all mming operations, has, in Nova Scotia, been unfortunately perpetuated by the system of letting areas and lodes to two or three working miners, who pay a percentage royalty on the Gold they extract.- On this subject, Mr. Poole very properly remarks : Report Dept. of Mines, 1873. ' ' A complete change has taken place in the system of working the Gold mines, and with the change there has been a great falling oflf in the number of men engaged, and a consequent decrease in the yield of Gold. The change referred to, is the almost total discontinuance from operating by companies and the introduction of the system of working the mines by tribute. " Two or more practical working miners agree among themselves to take a mine, often one that an agent for a Company has failed to work at a profit, for a term of six months or a year, with the understanding that thjy pay to the owners a percentage of the value of the Gold extracted. " Already it is shown that some of the leads abandoned by Companies can, in the hands of tributors working even under many difficulties, be wrought with profit and advantage. "The great objection to tributing, as now conducted, is the desultory methdft it introduces. The backs of the leads are stripped, and the trenches thus made, become reservoirs for water. No more timber than is absolutely necessary for the immediate safety of the mine, is, txa a rule, used, and in districts where the country rock is fissile, a crushing in of the walls sooner or later takes place. " Again, in 1874 : "In the last report, reference was made to the introduction of the tribute system of raining, by which working miners are enabled to utilize th*ir knowledge and labour to the greatdit advantage. It is, undoubtedly, the best adapted to foster a true mining spirit. As far as possible, it shoiUd be encouraged, and few ofiicial obstructions put in the way of working men willing i&l L 1 AND MINERAL LANDS. 45 to venture their labour in mining speculations. At the same time, it should not be forgotten that men of this class are almost always without the capital requisite to open the setts as thoroughly as even they themselves would approve of doing, had they adequate means ; but for the supply of their immediate necessities, they are compelled to extract quartz as speedily as possible, and get some return for their labor. The system, as at present conducted, is only adapted for surface workings, and where the water is light. It is attended by this great disadvantage, that the tributers' interest in the property they work, being merely temporary, they leave the small shafts and slopes imperfectly stowed and secured, in consequence of which rupture of the walls sooner or later taking place, allows free access for the infiltration of surface water. This admission of water is not of so much importance when the depth of the workings is shallow, but most serious when great. In most cases it ultimately leads to abandonment, due either to the want of cdpital necessary to erect pumping apparatus, or because the expense incurred by pumping becomes insupportable. Unfortunately this country is comparatively level, and wet, so that adits for unwatering a district can seldom be resorted to, and pumps have generally to be used. When mines have been abandoned and allowed to fill with water, much expense is entailed on the workers of leads in adjoining areas on account of the water, which finds its way down from the denuded outcrop and through the shattered rock. Were lessees to require proper attention to be paid to the protection of the outcroppings of the leads, either by requiring them to be left unwrought, or the excavated space be well packed, and the walls kept from fallinc; together, much of this trouble might be avoided. The lessees could make such stipulations with the tributers, and their agent on the ground could see them carried out. "Most of the claims are held in small areas, and while they are so, companies •cannot work to advantage. Capital might, perchance, however, be profitably invested by being more particularly directed to supplying efficient machinery to do the hoisting and pumping, the leads so drained and made workable being divided into setts and worked by tributers, at rates proportionate to the value of the quartz previously extracted from each sett. " 6:)i< The lodes are opened by shafts sunk on their dip, at intervals of 50 to 150 feet. These are connected by levels, and the vein-containing rock opened by stopes, arranged to suit the number of men, proportion of dead rock, etc. The stoping is generally under-hand, or a combina- tion of both systems, scaflfolds being placed for convenient stowage. After the rock covering the lode has been removed for some distance, the lode which has been secured temporarily in its place, is removed at one operation, and passed directly to the mill. The ore is hoisted and the pumps driven by every possible contrivance, from a steam engine to a wind-mill, and the mill engine is frequently employed for all these purposes. Few shafts have been sunk over 200 feet; the deepest beillg on the Wellington property, at 3herbrooke, which has reached over 500 feet. Dynamite is extensively used, and many hard bound lodes have been profitably worked by its application, which would otherwise have remained unattacked. As yet machine drills have •r i ■ J. znjsassi Ul!liUi!J_!i.^li!IL'!l.''K!'l!K!!JIJ»li!.'IB.i.w 46 NOVA SCOTIA MINES not been used, they have proved awkward in the narrow workings, which seldom exceed 2 feet 6 inches in width, and are moreover inclined. The distribution of the Gold in "pay streaks" is common to the quartz lodes of all countries ; and is connected with some law, concerned in the original lines of openings and pressure, whereby the various minerals were deposited in the lodes ; but, as yet, we al'e not in possession of the data for its practical application. In Nova Scotia, the dip varies from east to west, and each district has its own experience to guide the miners. It is to be regretted that no records or plans have been kept, for an accumulation of data would have proved most useful on this point. The streaks are found to vary in width, and sometimes to be lenticular, and to die out before coming to the surface. It thus happens that frequei.tly the miner finds himself confronted by barren quartz, becomes discouraged, and abandons his work, when prospecting tunnels might have disclosed another streak at no great distance. Dr. Sterry Hunt remarks : "To abandon a working on account of a momentary impoverishment of the lode, as has too often been done in this region, is therefore unwise ; and a large enterprise, where mining is carried on in several veins at a time, the richness of some of these may always be counted upon to compensate for the .temporary poverty of others. I am of opinion that an unnecessary discouragement has had as much to do with the failure of certain Qold- mining enterprises in Nova Scotia as the want of scientific knowledge and the neglect of proper preparations, and that many of these noW abandoned as unprofitable, will be again taken up with advantage. "-Gold Regions of Nova Scotia. This subject leads to the consideration of permanence in depth of the Gold yield ; in some districts it is considered that no Gold will be found in paying quantity, beyond a certain depth. This probably is a case of a pay streak lying in l comparatively horizontal position, and having an unproved interval of barren quartz below it. The depth to whici mining can be carried is so small when compared Avith the known thickness of the strata of the globe, and the distance through which the lode-forming agency has acted, that the work of the Nova Scotia miners appears but a scratch It will, undoubtedly, be found that there need be no apprehension of the limit of the latter in depth, being reached at distances less than those throUgh which we know them, from surface evidence, to extend horizontally in dii-ections parallel, and transverse to the anticlinal axe^; and as these distances are reckoned by thousands of feet, it may very safely be conjectured that there is practically no limit to the depth to which the lodes may be successfully followed. m AKD MINERAL LANDS. 47 The quartz passes from the shafts to the mill dump, where it is sorted and broken by hand for the stamps. The mills are of the common pattern, with revolving stamps, weighing generally from 550 to 700 tt)S. ; although a few mills run with 450 B)s. stamps, working in cast iron boxes. The batteries are provided -svith tables, and in some cases with secondary oscillating plates, or tail runs, with or without ripples. I believe the use of plates in the batteries has not been tried, at any rate, it is not in practice. The mills generajly comprise two or three batteries, of four or five stamps each, and are driven by steam or water, according to the facilities offered by the dislrict. This influences the cost of crushing, which varies per ton from 90 cts., to $1.60 for water, and from $1.50 to $2.50 for steam mills. The system of battery amalgamation is universally adopted ; the use of blankets is unknown, and no attempts, beyond an occasional settling tub, are nlade to catch any lost amalgam, etc. The methods outlined above, answer tolerably well, for much of the Nova Scotia Gold, which is present in a coarse, free form, but prove inadequate to treat fine Gold and that held in the pyrites. No regular system of assaying tailings and pyrites has ever been carried out here, but the tests made show what a shameful waste has gone on since gold mining began. The following results, from Prof. Hynd's reports, will show this point ; it being remembered that in practical vi^^orking,- these per-centages would seldom be realised : i u ,M i DisTKicrg. Per Ton.

Mr. Burkner sent to Freiburg, 1st — 850 Bbs. of pyrites from cleanings in stamper boxes, in which quartz of 2^ to 3 oz. 'per ton had been crushed ; the assay return was 8600 to the ton. 2nd. Two tons of pyrites from quartz from 15 dwts. to 20 dwts. to the ton, assay return $150 per ton. 3rd. 8 or 10 tons pyrites from tailings which gave $18 or $20 to the ton ; the first and second lot of pyrites gave about as much quicksilver as gold. "Assays made under my (Prof. B. ^illiman) directions on the waste tailings from "barrel quartz," run through a stamping mill at Waverley, showed the presence of nearly fifteen pennyweights of gold to the ton of tailings, not over eight pennyweights having been saved in the original working." The average amount of gold in the tailings, quartz, of our mills, may, according to Prof. Hynd and others, be averaged at 4 dwts. to the ton. Mispickel from the O'Connor lode, at Montagu, gave $276.49 per ton of gold and silver, A ton of pyrites crushed at Montagu gave 37 ozs. of gold, and the tailings of the crush assayed 1 1 ozs. ' The mean yield of two samples of tailings from Montagu quartz crushed at Waverley, gave Professor Silliman 16 dwts. 13 grs. gold per ton. " A series of assays proved that the tailings taken from the bank close to the Montagu mill contained $37 per ton, and gradually decreased towards thd furthest end of the heap, to 02. 80 per ton. A natural concentration had here taken place — the heavier portions, consisting principally of pyrites carrying gold, had settled close to the mill, while the lighter portions, poor in gold, were carried by the water to a greater distance. " When it is considered that auriferous Kulphurets are present in almost every lode worked, frequently in large proportions, and are also, in some districts, abundant in the enclosing rocks, there is evidently a field for profitable extraction of gold yet untouched. It has been stated that at least 20 per cent, of the gold originally present in the lodes, is allowed to pass through the mills, and ^o escape I If I i J fc ll l lW H »0 NOVA SCOTIA MINES to the nearest brook or pond, some mill owners boasting of their facilities for getting rid of the tailings. It would be useleife for me to repeat the advice that has been frequently offered on this point, or to bring forward the statistics of other countries as to the profitable treatment of pyrites, economy of milling, etc. ; but it certainly appears that a system of concentrating the sulphides, etc., and their subsequent treatment, would prove profitable. Those who desiro further information will find the subject treated of in Prof. Hynd's reports, the works of Smyth, Phillips, Kustel, and others.

The character of the gold at any particular mine is of more import- ance than generally supposed. Gold from Tangier, for example, yielded to Marsh, 981 parts cf gold ir 1000 of the native alloy ; whereas, gold from the Ovens gave the same assayist 920 parts to 1000, being a difference of 61 ounces in a thousand ounces of the metal. AKD MINERAL LANDS. 51 The loss of weight in smelting the rough product of amalgamation varies from one to fourteen ^er cent. The value of the gold liable to pay Government royalty is estimated at the rate of nineteen dollars ai\ ounce, troy, for the smelted, and eighteen dollars for the unsmelted metal. In the preceding pages I have endeavored, as concisely as possible, to lay before you the extent of the country containing gold, as yet undeveloped and almost unprospectod ; and to show that in every dis- trict the careful miner has succeeded in his operations. The ground already worked, and affording space for still more extensive mining in the future, is very large, as will appear from the number and extent of the districts. The nature and contents of the veins and associated minerals have been shown by the ores will be noticed as ^;hey are successively met. * The Geological ages are taken from the reports of the Geo: Sur:, and Dr. Dawson's Acadian Geology. AND MINERAL LANDS. 53 In the dykes and niames of trap associated with the Triassic sand- stones of the south side of the Bay of Fundy, are numerous veins and pockets of magnetite and red hematite, as far as known, not exceeding in any case, one foot in thickness. The magnetite is generally very pure, the chief foreign ingredient l^ing silica. It is usually massive, sometimes crystallised in dodecahedra and its combinations in partly filled veins, and associated with quartz, colourless and amethystine. v. Near Digby Neck, it is found with red hematite, and several hundred tons have been extracted for smelting. The following analyses, by Dr. Howe, are of the common compact magnetite from localities in the trap : i Quartz 6'46 4*94 Magnesia and traces of lime 1*27 4 '84 Oxygen 2494 2519 Metallic iron 68-33 6503 The magnetite also occurs disseminated where no ore is visible, and may be separated by means of a magnet from the powdered trap of several localities. * both varieties containing a large amount of titanium and a little magnesia. This ore is reported from Shelbume, on the Atlantic coast, and from Musquodoboit, near Halifax, that from the latter place being a dark grey micaceous schist, holding crystals of magnetite, with titanium I Red hematite is found at a number of places associated with agate, quartz, and calcite. It is sometimes presented in the form of small crystalline plates, in a granular quartz matrix and sometimes as crystals, apparently showing its derivation from magnetite. Much of the ore is ^ [ decidedly magnetic, especially the more highly crystalline specimens. This range of trap extends from Blomidon to Briar Island, a distance of 1 20 miles, and contains these ores everywhere in it ; but as yet no veins have l>een found large enough to allow of systematic mining. TITANIFEROUS IRON ORE. This is found at St. Mary's Bay, west of Digby, as sand, forming bands of irreguar extent in the beach. The indications are extensive, but no attempts have been made to test their value for working. A sample yielded : Magnetic ironsand, or iserene 30 Non-magnetic, or ilmenite 56 Silicious sand 14 4 J i * 'i .\. ^ ., !T'- \m 54 NOVA SCOTIA MINES in considerable quantity. The writer has also found an ore of similar appearance, near Sutherland's River, Pictou Co., containing decided traces of titanium. An attempt had recently been made to work titanic iron ore at Bay St. Paul, on the north shore of the Gulf of St. Lawrence. The ore, cjjntain- ing about 36 per cent, of iron, 44 of titanic acid (and, according to Dr. Penny, no mangane.«^e, sulphur, cr phosphorus), 'occurs as a bed about 70 feet thick in a rock of anorthosite of Huronian age. The dimensions of the furnaces are as follows : Height 30 feet. Diameter at hearth , . , 4 " Diameter at boshes 14 " Diameter at throat 8 " Each furnace has three tuyeres, the blast being heated by waste gas taken off by a cupped cone, and applied at a pressure of 1| ft). The fuel used was exclusively charcoal, 200 or 250 bushels being required for each ton of pig. The dailv product of each furnace did not exceed five tons. The pig made w white and of fair quality ; but the large amount of fuel used presented a formidable obstacle to profitable work- ing. The following is an analysis of the pig by Mr. Edward Riley : Carbon 3-966 Silicon -086 Sulphur -030 Phosphorus •263 Chromium -689 Manganese ) , Titanium j ' Iron r.: 96-245 The beneficial effects of titanium, formerly dwelt upon, are hardly borne out by practice, and it may, perhaps, be more justly regarded as a foreign ingredient that must be made to pass into the slag, thereby causing a loss of heat. While in this connection, it may be stated that iron sand is found at various places along the Gulf of St, Lawrence, the Atlantic coast of Nova Scotia, the Bras d'Or Lake, at Amaguadees Pond, and the west coast of Newfoundland, where in many places the iron sand is chiefly composed of magnetic ore. The ores of Clementsport, near Annapolis, next claim attention. Here a narrow belt of strata of Devonian age, according to Dr. Dawson, TTf AND MINERAL LANDS. 55 three to five miles wide, rises from under the Trias of the Annapolis Valley, and pursues an east and west course for about sixty miles. At one point it is divided by a mass of granite into two nearly equal portions. In the western division are the Clementsport, and in the eastern the Nictaux ores. ^ At Clementsport there are two beds of ore running nearly east and west, and underlying to the south at angles of 75 to 80 degrees. The highest of these, the Milner bed, varies in thickness from two to four feet. It is specular ore metamorphosed with magnetic properties, and still retaining casts of virelebite, spirifers, and associated moUusks. The ore, which is of fair quality, yields about 33 per cent, of metallic iron. It is mined by open cast, and costs $1.40 per ton for extraction. The Potter bed is a magnetite (]), and presents the following section where worked : ■ Ft. In. ■ . Ore 3 Slate 2 6 Ore 3 6 9 It is compact, and of a dark grey color. The writer has seen no analysis of it, but it is stated to yield 15 per cent more iron than the Milner bed. BLOOMFIELD BOO ORE. This is found at several places in the vicinity ©f the above deposits, and yields 25 per cent, of iron. It occurs in layers, six inches to two feet thick, covered by a few inches of soil. Considerable quantities of it have been extracted at a cost of 40 cts. per ton, for mixture with the other ores. A blast-furnace was erected here about twenty years ago, and has boon running several times since. It is of similar dimensions to those built at Bay St. Paul, but 2J feet narrower at the boshes. The blast is supplied by a water-wheel through three tuyeres, at a pressure of If to 2 lbs. The blowing cylinders are three in number, of cast iron, four feet in diam'jter, and four feet stroke. The blast is heated by burning the waste gas in an oven with seventeen syphon pipes. Mixtures of all the ores are smelted, yielding an average of 35 per cent of iron. 130 (Winchester) bushels of birch charcoal, costing 4 to 6 cts. per bushel, / 56 NOVA SCOTIA MINES ^."^.l are required to make one ton of grey pig. There are forty-five charges in twenty-four hours, consisting of from 700 to 800 D)s. ore, 120 tts. lime- stone, and 16 bushels of charcoal, yielding daily about five tons. These ores cost at the furnace, including mining and hauling two to four miles, from $1.00 to $1.75. Indications of the eastern extension of these ores are met in the vicinity of Annapolis, and elsewhere in the South Mountain range. At Nictaux, 37 miles east of Clementsport, a furnace was built to work similar ores, but is now abandoned. The bed which was worked to supply the furnace is a highly fossiliferous peroxide of iron, associated with coarse dark slates, dipping S. 50° E., at an angle of 60°. It has been traced about four mileS; and found to vary in thickness from three to four and a half feet. Dr. Dawson states that the fossils of the red hematite and associated beds are Spirifer arenosus, Strophomena depressa, Strophomena magni- fica, Atrypa unguiformis, and species of Avicula, Beilorophon, Favosites and Zaphrentis, Tentaculites, and a coral considered by Mr. Billings identical with the Pleuro-dictyum problematicum, Goldfv.83. These Professor Hall compares with the fauna of the Oriskany Sandstonda, and they seem clearly to prove that the beds of Clements and Nictaux are of lower Devonian age. It may be remarked that Dr. Dawson's conclusions are questioned by Dr. Honeyman, who is inclined to con- sider these ferriferous strata of much greater age. The public will await with interest the results of the work of the Canadian Geological Survey, which will, with the aid of their systematic surveys and levels, define more closely the lines of contact of the various systems than any labours of unaided individuals. Should it eventually prove that iron ore beds of more than one age are present in this district, the extent of ore-bearing ground >vill be greatly extended both in Nova Scotia and Cape Breton, where the last report of the Geological Survey indicates beds compared with the Devonian of other localities. The per-centage of iron realized in working was about 50 per cent., but the amount of phosphorus present, and the expense of transport, were against the success of the enterprise. Purer ores are now known in the district, and it is intersected by a railway, so that the proposed resumption of smelting has more chance of succeeding. AND MINERAL LANDS. 67 . * *In 1855, Dr. Jackson, State Assayer for Massachusetts, wrote : " One cannot fail to be surprised at the enormous quantities of ore which are already exposed by the numerous openings which have been made. There are several distinct and parallel beds of iron ore which we examined, from four to ten feet in width, extending, certainly, no less than five miles continuously. * • The supply of iron ores at Nictaux is inexhaustible." A short time before. Dr. Hayes described the ores of Nictaux, and spoke of the magnetite on the west side of the river, of the less compact bright red ore of Little River, and of the bog ore of the valley. Mr. Mushet, writing to Mr. C. Archibald, said : ** The shell ore is quite a novelty, and the magnetic character of some of the pieces contrasts strongly with the inert state of others to all appearance of similar composition. I have examined it, and find that it is curiously composed of magnetic and non-magnetic laminse. The assay of the former give 67f per cent, of iron, and the latter 54 per cent," The promoters of the Nictaux and Atlantic Railway, now being constructed from Nictaux to Bridge water, turned their attention, in 1870, to the magnetic ores of the Cleveland Mountain, as far as Lawrencetown, a distance of 6 miles to the west of the river, where the strata are finally cut off by the granite. In the neighbourhood of the river they exposed many beds of ores, ranging in width up to 12 feet. The general course of the metalliferous belt is N. 55° E. Six miles east of the river the transition of the magnitites" into hematites takes place. On Foster's farm (late N. Parker), the fossiliferous ore of the charcjoter described by Mr. Mushet, is met with, and within 100 yards of it, on the same course east, red hematite makes its first appearance. West froi. this point, on the Canaan »'oad, fossils are abundant in the magnetite, but they become less and less distinct, until beyond the river all trace of them has disappeared from the magnetites*. The hematite beds have been exposed on the farms of David, John and Ingraham Banks, 4 miles east of Canaan, on the Williams River; and they have also been reported at Aylesford, 4 miles further esist. One bed is highly fossiliferous, the others are compact and readily cleaved. Meadowvale, where this ore was opened, is only some two miles from the Annapolis Rsffiway. Bog ore of superior quality is found -in the valley at several places between the farm of Er Payson, at Meadowvale ; and J. Wheelock's, at Middleton; and on to J- Beales', at Ingles'-ille, a distance of 10 to 12 miles. The ore is of the character called " Pitchy Hydrate," and affords 47 per cent of iron. '* H. S. Poole, Esq., Report Department of Mines, 1S77. 11 68 NOVA SCOTIA MINES It is to be hoped that some of these ores will be found adapted for exportation ; and in this event, the proposed railway will afford a con- venient outlet to a shipping place. Their character will be seen from the following analyses, by Dr. Waltz, of New York, and Dr. Dro^vn, of Philadelphia : Metallic Iron Silica Sulphur Phosphorus Alumina Lime Magnesia Oxide of Manganese .

Specimens can be got showing the gradual change from normal hematites, with cherry-red powdcr,,to magnetic ores, with brown or black streaks. This is probably a local metamorphism, due to the presence of organic matter and the granite dykes which traverse the rocks in the vicinity. From the country lyirtg to the south of the district above described, and extending to the east as far as Windsor, the writer has received specimens of red hemitit^, specular and bog ore. As yet, these ores are not known to exist in quantity, but there has been no inducement to search for the beds in situ. At Goshen, between Windsor and Truro, a vein of ankerite contain- ing limonite has been opened in strata of the Marine Limestone age, and proved vo be 40 feet wide. The following analysis of the ore is interest- ing from the amount of manganese present. In connection with this ingredient, it may be stated that large quantities of manganite and pyrolusite have been mined and exported from this district.

AND MINERAL LANDS. 59 Iron pyrites "20 Phosphoric acid « -21 Water IMO At the mouth of the Shubenacadie river, the lowest visible carboni- ferous bed is a dark laminated limestone, which, with the overlying sandstones and marls, contains small veins holding limonite and specular ore, with ankerite, barite, calcite, goethite, manganite, and siderite. In the same formation, a few miles to the eastward at Clifton, similar ores are found. At this point they are of more importance, one of the limonite veins being six feet wide. At Brookfield, ten miles south of Truro, in measures of the same age, and near the contact of older strata, are extensive surface indica- tions of limonite. As yet but little has been done to test the deposits. An engineer of some repute in reporting on the property said: "I consider that the indications of an extensive deposit are greater than even at the Londonderry Mines." This deposit is very favorably situated, being only two miles from the Intercolonial Railway, and about forty-five miles from the Pictou coal field. The ore is of unusually good quality, as will be seen from the analysis of Dr. How, of King's College. Water 11'36 Silica & Gangue 1*54 Phosphoric acid trace. Sulphuric acid none. Magnesia trace.

The next ores to be noticed are these limonite deposits, which are hardly equalled for extent, facility of access; and uniformity of quality. At the mines, the Cobequid Hills, marking the di^n^ion between the water- sheds of the Gulf of St. Lawrence and the Basin of Minas, form an immense mass of Upper or Middle Silurian (f) strata, highly metamor- phosed, and containing dykes of syenite, etc. The southern slope of these hills feeds numerous large brooks, which have cut for themselves channels, frequently 300 feet deep, and which afford unusual facilities for tracing the ore, as well as for studying its position. A good idea of its mode of occurrence may be gathered from the section exposed in the brook near the site of the old charcoal furnace. i'i' 60 NOVA SCOTIA MINES li ,:| m M ;: r^f Here is a series of red and gr^ shales and sandstones of lower carboni- ferous age, dipping south at an angle of 60° lying on vertical black and olive slates and quartzites of the Upper Silurian age, striking north 31 ' east. This line of contact has been traced about twelve miles along the hill sides, or across the property of the company, and affords a key to the position of the ore vein, which is always found in the Silurian strata, at a distance varying from 300 to 500 yards from the lowest met car- boniferous bed. Another parallel vein is known one-half mile further north, but has not yet received attention, owing to the ample supply at present developed. The vein rock consists of a mass of ankerite, varying in width from 30 to 160 feet, and holding in places brecciated masses of quartzite and slate. The ore occurs in minor veins in the ankerite, and is found to be from 5 to 50 feet in width. The chief ore is limonite, which is found in the bptryoidal, stalactitic and compact form, but considerable quantities of micaceous hematite have been met.* The following are analyses of the two chief ores met : Limonite.

AKD MINERAL LANDS. 61 The latter, which is a variety of siderite, is becoming so abundant in place of the ankerite that it is anticipated that it will prove a valuable ore, when the lower parts of the deposit are reached by the miners. The ore is won by levels driven to cut it at depths of 200 or 300 feet, and workings adapted to the shape and size of the deposits. For many years this large body of ore supplied only a small charcoal furnace, from which about 40,000 tons of excellent pig were made, the following analysis of which is by Tookey : Carbon ' 3-50 Silica .'84 Sulphur -02 Phosphorus '19 Manganese "44 Iron 94.85 The furnace is similar to that erected at Clementsport, already refer- red to, and is supplied with cold blast by means of a water-wheel. The following are the amounts of ore, fuel, and flux used in August, 1873:— Ore— Limonite . : 421-3 Fuel— Charcoal 32-000.00 bushels (Imperial.) riux— Ankerite 68-7 tons. Pig iron made 221.00 tons, or 7-13 tons daily. From which the estimated cost of a ton of pig iron would be about $19.00. Recently the property, embracing 55 square miles of freehold, has been purchased by a number of gentlemen, forming the Steel Company of Canada. Since that date the property has been developed on a scale commensurate with its importance, and numerous levels have exposed large bodies of limonite, aflfording a supply suflficient for years of steady work. The following items are from the Reports of the Department of Mines : " A narrow gauge railway, 2 J miles long, has been built from the west mines to the furnace, and a broad guage line, 5 miles long, from the east mines to Debert Station, on the Intercolonial Railway, beside a branch 3 miles long from Londonderry Station to the Works. I .J !ii I I f 62 « . NOVA SCOTIA MINES Two blast-furnaces, 65 feet high, 19 feet in diameter at the boshes, and 5 feet at the hearth, have been built, and are expected to yield 650 tons a week. Since 1876, 99,366 tons of ore have been smelted, which have yielded about 40,000 tons of pig iron. The materials smelted in 1877, were : Iron ore 20,270 Ankerite 1,850 Limestone 6,520 Coke ; 15,970 Iron made 9,863 The blast has a pressure of 2-4 tt)S. heated in three Oowper Siemens' stoves to from 800°-1100° Fahr. The blowing engine has the steam cylinder above the blowing cylinder, which has a stroke of 5 feet, and a diameter of 6 feet. Water is brought in a flume 3460 feet to the blast furnace, and 4060 feet to the rolling mill. There have been built six single puddling furnaces and one double, two more double furnaces are in process of construction ; and there is one heating furnace — in all having a capacity of 25 tons of finished iron per day. There are two trains of rolls, one 9 inch and one 16 inch trains; two steam hammers, one 20 cwt., and one 50 cwt. The bar iron made, according to Riehle Bros, tests, is " ductile and fine grained ; " Tensile strength 60,000 Yba. per square inch, and elonga- tion 33 per cent.

'' The fuel used is coke from tlie Main Seam, Pictou Co., already referred to, and coal from the Intercolonial Mine, coked at the works. A certain per-centage of raw coal is also used, and has been found to work satisfactorily. The quality of the pig and bar iron, etc., made at these works by various processes, is of the very best, and adapted for every work re- quiring those qualities which, seldom attainable except at ruinous prices and by means of expensive mixtures, are here presented ready for the smelter. The report of the Canadian Gun Works, at Montreal, on the quality of the Londonderry bar iron used in the process of converting the old cast iron 62 pounders, shows that its quality is superior to that of the best English and American iron. The Londonderry ores are known, from surface indications, to extend over twenty-five miles to the west of the lands controlled by this com- pany, but no attempt has been made to prove their extent. In the natural sections of the carboniferous measures exposed at the Joggins, are numerous balls and irregular bands of ironstone, not, how- ever, yet considered of economic importance. At various points in the carboniferous district of this County, are found deposits of bog ore, but their extent and quality are unknown. Other localities that have yielded specimens of iron ore are, Clark's Point, , PatTsboro, Joggins, Cape Sharp, Fullerton's Lake, etc. PICTOU COUNTY. — IRON ORES. The iron ores of this district are more varied and of greater extent than elsewhere in the Province, and, from their relation to fuel, flux, and shipping, are destined to play an important part in its future development. . Although the existence of iron ores on the East River of Pictou was known for many years, it was not until 1872 that any systematic attempts were made to test their extent. As early as 1828, or shortly after the (Jeneral Mining Association of London opened their Pictou collieries, a blast furnace was erected at the colliery, and a small quantity of red hematite and limonite smelted ; but the expenses of hauling the ore twelve miles, soon put an end to the work. Nothing was then done until, in 1872-3, extensive explorations were carried on under the super- ,1 :ilf iU 64 NOVA SCOTIA M1NE8 I *: Tision of Dr. "Dawson, and continued for several years from that date by the writer. Taking the ores in descending geological order, the first to be noticed are the bog ores. These are scattered over many parts of the county, notably on the West Branch and the head waters of River John. Several small deposits have been found near French River, of which an analysis, by the writer, is given below. They also occur north of New Glasgow, and are apparently derived from the conglomerate already referred to, as limiting the ooal field. We have next to notice the Clay Ironstone ores of the Pictou coal field. They form irregular beds from 5 to 40 in. thick, and are found everywhere in the coal measures, in some cases forming part of the seams. But little attention has yet been paid to them. From the writer's analysis given below it will be seen that they are of good quality, and is it considered that they will prove an important addition to the older ores. At French River, in the Marine Limestone formation (?), are numerous beds of Clay Ironstone Carbonates, and Hydrated Peroxides, in beds from 6 in. to 4 ft. in thickness. The discovery is a recent one and little ig yet known about the deposits.

The contain- ing strata were formerly considered of Millstone grit age ; but, from the proximity of gypsum and limestone, they would seem rather to belong to the Marine Limestone formation. As far as can be judged from a a AND MINERAL LANDS. '65 rough survey, this ore is found at a horizon 800 feet lower than the "Ironstone of French River. The bed dips south at an angle of 60 degrees, and varies in thickness from 6 to 10 J feet, and has above and below a small bed of the same, 6 to 10 inches thick. The ore is a spajry carbonate of iron, holding peroxide in places, with a variable proportion of manganewj, and very little sulphur and phosphorus. Superficially it is rusted, but where unweathered, of a pearly grey colour. From surface indications, it appears probable that this ore extends over a considerable district, and the MTiter is inclined to consider it characteristic of a horizon low down in the Marine Limestone.* Analyses of Spathic Ore from Sutherlami's Brook.

At several points along this line a very fine deposit of Limonite has been proved. On the property of the Halifax Co., some years ago, the writer proved it to have a thickness of 21 feet 6 inches, and recent researches have proved it to be 15 feet thick on the Saddler area of the Pictou Coal and Iron Co., and an equal development at other points. The ore is compact, concretionary, and fibrous, with considerable quantities of gravel ore. At two points the ore has been proved to rest on the Silurian clay slates, and has Limestone on the hanging wall, usually with a gore of red clay, frequently holding concretions of Man- ganite and Pyrolusite intervening. These ores are very pure, and appear to be much more free from phosphorus than the Londonderry limonite, the average of five analyses of the East River ore giving -118 phosphoric acid, or '083 phosphorus, in 100 parts of iron. * See paper on the " The Limonite and Limestones of Pictou Co.," by E. Gilpin, TranMctions N. B. I. N. B., 1878-79. €6 VOVA SCOTIA MlirU These ores in places hold notable quantities of Manganese, and resemble closely the Spanish Limonites imported into England.

The Limonite may have been derived, like the Limonite of Cumber- land district and other localities in Pennsylvania, as a residual precipitate from the disseminated iron sand grains of the Upper Siljiian strata as well as a deposit from the gradual dissolution of the Marine Limestones. In view of this, it may be stated that in this district the rocks of both ages contain considerable quantities of iron as carbonate and peroxide, and that the erosion has been on an enormous scale. This has been fully treated of by the writer, in a paper read Feb., 1879, Institute of Natural Science, Halifax. It may be mentioned here that some of the East River limestones may be found valuable iron ores.

The following arc among the more common fossils of this district : Favosites, Zaph- rentis, Chonetes tenuistriata, Spirifer ru|;flecosta, Strophomena profun- da, Rhynchonella spirata, Atrypa reticularis, Athyris didyma, Megam- bonin striata, trilobata, Orthoceras sev. sp., Cornulites, Dalmania Logani, etc. The chief ore of this formation is a bedded Red Hematite found in four principal deposits. The most northerly of these is known as the McKenzie red^ematite. It appears from surface indications to be ef large size, but no work has yet been done to test it. The next bed, known as the Webster ore, has l)een carefully trenched and tested at several points, and extends about 3 miles. Its thickness varies from 15 to 30 feet, its dip being generally north at angles varying from 25° to 60." At two points it presents the following sections : Ore Smooth parting... Ore Slate Ore Ft.

The ore is compact, non-fossiliferous, and brick-red when weathered. The third exposure is known as t|j,e Blanchard great bed. No attempts have yet been made to ti-ace it beyond the natural exposures which extend about half a mile. It varies in width from 30 to ^100 feet, measured across a dip nearly vertical. It is also situated on elevated ground, and would yield a large amount of ore. At a geological horizon about 700 feet higher than the last-mentioned bed is a conformable range of Red Hematites forming the fourth series. This ore appears to form a synclinal trough. On the west side the ore iii i' Iftl' . . ' NOVA SCOTIA MINES is 12 feet thick ; at the apex there appear the outcrops of two other beds eight and three feet in thickness, the laiger possibly representing the great bed at Blanchard. On the east of the synclinal, only one bed has been opened, varying in w^idth from three to five fe- 1. Underlying this bed, and on the line where the great bed would show its eastern outcrop, are large boulders, precisely similar in appearance to the ore on its western outcrop, and it is expected that it will shortly be found here. It is considered by some geologists that the large single beds were originally one, and owe their present disjointed condition to faults and erosion ; no detailed survey, however, has been made to prove the cor- rectness of this opinion, and at present it can only be said that they are apparently contained in a limited vertical range of strata. The outcrops of other Red Hematites have been detected, but no work has yet been done to allow of details. " '..■■• '■ ': -• These Red hematites are all of the same class, being of a red color, with earthy to steely lustre, compact or laminated, sometimes oolitic, owing to the peroxide forming minute concretions around grains of^and. In places these ores contain fossils, but the larger proportion are quite free from them. They are .excellently adapted for mining, being 6n high ground, with good roof, and requiring little or no dead work. Similar ores, called fossil Red Hematites, are found in Pennsylvania, in strata of the Clinton age, and extensively worked near Tyrone, for mixture with rich hematites and Magnetites. The following analysis will show its relation to the Pictou ores, of which analyses are given further on.

The Pictou Coal and Iron Company own over two miles of this vein, in addition to large and well selected areas on the Limonite, and the Webster and other Red Hematites on the east side of the river. At two points, a vein of a mixture of specular and magnetic ore, one to two feet thick, has been met, but no work has been done to test its value. The main vein is cut by several ravines, and for some distance runs close to the brow of a hill 200 feet high, which would be found advan- tageous in mining. <>,t- About two and a half miles to the westward, and nearly on the strike v/f the specular ore, a large body of reddish quartzite is found in similar black slates, and holds several veins of Limonite from one to three feet in thickness. The bed rock has been traced some distance, and is capable of yielding a considerable quantity of ore above water level. The ore is compact, of a chocolate colour, with small cavities lined with crystals and plates of the same mineral. Near Glengarry, specular ore is again met in small veins, in a yellow- ish gray quartzite, but no work has yet been done to test its extent. At numerous other points in the county, rocks of Silurian and Car- boniferous age, and some of the traps, contain crystals and veinlets of specular and magnetic ore, as traces of metamorphic action, as well as indications of permanent deposits, but little attention has been paid to them, beyond the district described.

Mary River, are reported large beds of limonite. At Arisaig, in Upper Silurian strata, a bed of red hematite, three feet thick, has been found. From specimens that the writer nas seen, it appears similar in character to the bedded hematites just described, but less silicious. This bed is found at the eastern end of the Lower Helderberg strata just referred to, and in the long range intervening new dis- coveries may be confidently anticipated. A large amount of money has been expended in testing the iron ores of Pictou County, and it is to be hoped that, at no distant date, smelting operations will be started. In this county, iron, coal, and limestone are all within a few miles of each other ; and there is a ready outlet by rail and water. Certainly, at no other point in the Dominion are the natural facilities greater for such operations ; e,nd every visitor to the iron beds is astonished at uheir extent and value. There are other eres in the district, specimens of which occur in tha drift ; but the beds themselves are not yet discovered, so that the field ^ for the iron smelter appears unlimited. CAPE BRETON. Our knowledge of the iron ore of this part of the Province, i§ limited, no work having been done beyond a few trenches across the outcrops of what appear to be promising deposits. At Loran, near Louisburg, boulders of a compact Red Hematite of excellent quality, have been found, but the writer is not aware of any attempts to prove the ore in situ. Tha following analysis of it is by G. F. Downing, of Workington : Peroxide of iron 90'14 Lime and Magnesia 4*20 Sulphur^. -10 Phosphoric acid 11 Silica 5-45 Thia ore r -sembles some of the Cumberland (England) Red Hema- tites in appearance and quality. At the summit of the Lower Carboniferous, as exposed near Sydney, is a thick bed of red marl, with thick nodules of limestone. Near the top of this bed is a hard grey sandstone, containing a variable amount of peroxide of iron, in places equal to 30 per cent, of metallic iron. Attempts to work this ore proved unsuccessful, owing to its irregular quality and distribution. kSD MIKBRAL LANDS. 71 At Big Pond, East Bay, Bras d'Or Lake, near the contact of Lower Carboniferous Conglomerates and Laurentain measures a deposit %f ochreous red hematite, considered to be of large extent, has been tested- The ore, as will be seen from the analysis given further on, is of excel- lent quality, and should find a ready market as a first-class Bessemer ore. Near the crossing of the French Vale and Bourinot roads, about 17 miles from Sydney, Hon. Mr. Moseiey has tested an important discovery of red hematite in the George River, (Laurentian) limestones. The bed runs north-east, and varies in thicknesa from five to nine feet, being included between two beds of white and light blue crystaline limestone. The ore is said to have been traced for ajjUpBiderable distance by pits and exposures. From the analysis given further on, this ore is also a very valuable one, and should find a r^ady market at Philadelphia and New York. Hon. Mr. Moseiey subsequently discovered the ore on widow Campbell's land, two and a half miles distant, with similar surroundings. This discovery is important, i.s it offers a hope that similar valuable beds may be found Jn other exposures of these limestones. Red hematite is frequently found among the Lower Silurian slates and limestones of St. Andrew's channel, and these may prove workable at some points, as for instance, near McSween's Brook. Traces of magnetic iron ore and hematite are widely distributed among the marbles of George's River and the limestones of Boularderie. At Whyhogomah, on the Bras d'Or Lake, on the property of the Inverness Coal and Iron Company, nine deposits have Ijeen exposed and proved to form beds in measures of Laurentiar age. They were traced some hundreds of yards, when further explorations were stopped by the heavy covering of soil. The ore appears to be a mixture of red hematite and magnetite in varying proportions. From the analysis by the late Dr. How, and Prof. Hayes, the ore appears to be very free from all impurity, except silica, the proportions of sulphur and phosphorus being small. A great point in favor of these deposits, and what are supposed to be their continuation in the district, is the presence of deep water within a few hundred yards of the ore, which would allow vessels of large burden to load for distant markets ; while it can be cnrried in scows or bargesto any part of the Bras d'Or Lake. 72 NOVA SCOTIA MINES Analyses of Cape Breton Iron Ores. -4' Composition.

Sur. Bsp. 1876-77, writes that the univer- sal occurrence of calcspar and hematite among the Laurentian, Silurian, and Carboniferous measures of Cape Breton County is remarkable. To the latter all the red rocks owe their color, and in places it separates into veins and strings. Near McDougal's Point, Big Pond, a limited deposit of excellent quality was seen at the junction of Carboniferous conglo- merate with Syenite ; at McNeil's mill, on the Glengarry road, similar traces have been met ; and large boulders occur at Loch Lomond post office. It is also present in the limestone of Boularderie, most of the Lower Silurian rocks, and many of the pre-Silurian felsites, in many cases, however, too much disseminated to be of economic value. Spathic iron ore occurs with the Lower Carboniferous marine lime- stones of Island Point, Boularderie, ir a bed 2 to 3 feet thick, yielding 32-58 per cent, of metallic iron. In this connection, reference may be made to the spathic ores of Fictou County. Bog Iron ore is found in a bed 2 feet thick, at J. McSween's, Fox Brook, Boisdale, and in a marsh near the Bourinot road, and at several points on Indian Brook, A deposit of excellent quality has been observed near Schooner Pond. Iron ores ai-e reported from many other localities in Cape Breton > but as yet little work has been done in the way of testing their extent and quality.

As the labours of the Canadian Geological Survey have been confined as yet to a small portion of the Province, it would be premature to venture to point out localities likely to contain iron ore beyond those described by Dr. Honeyman and Principal Dawson. The discoveries by Hon. Mr. Mosely, referred to above, are among the most important, for they lead to a hope that the Laurentian, or according to the proposed grouping of the survey, the Huroruan strata of Nova Scotia, may be found specially worthy of the attention of the miner. The most important of the Canadian iron ores are found in strata of this age, and the catalogue of Canadian Minerals sent to the Philadelphia Exhibition, contains notices of many such deposits. In the various divisions of the Silurian strata, stretching from Canso to Yarmouth, beds and veins of iron ore occur, and the point or vicinity of contact of these measures with the carboniferous has frequently shown evidence of valuable deposits. The gold-producing rocks of the Atlantic i i w f I' 74 NOVA SCOTIA MIKES <;oast !iave, so far, I believe, not yielded deposits of ore considered of workable size. Deposits of bog ore are found scattered in all parts of the Province ; few of the beds have been tested, but shoi'ld any demand arise, a very considerable quantity could be obtained for mixtures with other ores. When the lack of interest, the want of information, ^d the thinly settled state of the Province are considered, it must be admitted that the discoveries made promise well for the future. As the country gets more settled, fresh discoveries may be anticipated, for nearly all the ores mentioned above were disclosed by the plough or natural exposures, and as the greater part of the Province likely to contain ores is wooded, there will probably be no deficiency of the raw material. It may be anticipated that the eflfect of the^firotection imposed by the Dominion, on the manufacture of iron, will shortly have the effect of inducing the opening and working of some of the above described de- posits. ' . When it is considered that the value of the imports of iron, rav/^, partly and completely nfanufactured, was, during the fiscal year, 1877, $10,400,000; 1878, $9,215,000; and 1879, $7,916,846 ; it will be seen that an ample field is open for our iron workers. When once such operations are commenced, it will be found that many of our ores offer facilities for the manufacture of high grades of iron and steel which can be exported. There can be no doubt that the increasing advantages steamers offer for freighting will cause our ship- builders to consider if they cannot build iron vessels here also. In no long lapse of time, unless they do so, the Province must gradually lose its present profitable business of building and sailing vessels. In this connection, the important fact must not be forgotten, that in Nova Scotia alone, of all the Provinces of the Dominion, the ores, fuel^ and fluxes occur close together, and therefore it is from this Pro- vince that Canada must draw its future supplies of iron. THE COPPER ORES OF NOVA SCOTIA. Although for many years the presence of various ores of copper was known in this Province, it is bu^ recently that discoveries of economic value have been made. In the early French expeditions to Canada and Acadie (now Nova Scotia) were men similar to those styled by Sir Humphrey Gilbert V. AND HINERAL LANDS. V. . ** rare refiners of mines ; " and their reports on the supposed mineral wealth of Nova Scotia and Cape Breton excited much interest in Paris, and formed one of the reasons that France struggled so strongly to retain her supremacy in British America. Lescharbot, writing in 1609, speaks of the native copper of the Bay of Fundy as being " very pure in the stone," and adds, " many goldsmiths have seen it in France, which do say that under the copper mine there might be a golden mine, which is very probable." The stone he alludes to is the trap associated with the Triassic sandstones of the Bay of Fundy ; copper is found scattered through it in small grains and lumps, but has not yet been found in workable quantity. Much money has been spent at various times in testing these indications. As is usually the case with copper ores, many deposits, at first very promising, Jiave proved valueless ; but some have been found under workable conditions. In this Province, the ores occur in rocks of every geological age met in descending order, from the Triassic downward. The trap of the Bay of Fundy has, as already noticed, from the earliest days of our history, yielded grains and lumps of metallic copper, sometimes weighing fifty pounds. Attempts were made, some years ago, to mine it near Margaretsville, on the shore of Annapolis County. The copper occui'red, associated with zeolites and other infiltrates, but it proved to be too irregularly scattered in the matrix to permit systematic mining. It is found at many other places, among which may be men- tioned Cape d'Or, Spencer's Island, Five Islands, Briar Island, etc. The trap of this locality is considered to differ widely in age from that associated with the Huronian copper-bearing strata of Lake Superior, which has yielded the metal from pre-historic times. But, when it is found In the Bay of Fundy trap, at so many localities, there will always be a strong inducement to test the more promising exposures ; and 'it may be found in places to be scattered in the trap, in fine grains, in quantity sufficient to allow of its being profitably extracted. It may be mentioned, in this connection, that I have observed metal- lic copper in dendritic forms in the copper ores of Antigonish County^ and Mr. Barnes repotted finding it near Cheticamp, Cape Breton. The upper and lower coal measures of Pictou, Cumberland and other counties, frequently show outcrops of nests and layers of the vitreous ■es 76 NOVA SCOTIA MINES '{ sulphuret and green carbonate of this metal, associated with jet-liko coaly matter. These deposits are believed to have originally consisted of accumulations of vegetable matter, in the swamps and estuaries of that age, and afterwards when the strata became solidified, that the ores of copper were deposited from their aqueous solutions, through the not yet clearly understood medium of the carbonaceous matter they have now partly or completely replaced. .. Such d^osits have been observed and tested at many points in the Province, among which I may mention the East River of Pictou, near Hopewell, and below Springville, West River, near Durham. The following is Dr. Dawson's analysis of a sample of these ores, from Carribou, near Pictou: ;' ., , Copper ,. 40-00 Iron 11-06 • Cobalt • 2-10 \ Manganese -50 Sulphur 26-42 Lime -92 Carbonic acid. Silica, etc 20-00 • . 100-00 Other localities are Salmon River, near Truro ; Athole, Stewiacke, etc. An interesting deposit, belonging to this class, is found on French River, above Tatamagouche. Here, in the upper coal measures, are several beds of argillaceous sandstone, and conglomerates, holding nodules and seams of vitreous copper and green carbonate, associated with so-called lignite. The ore is rich, holding up to 74 per cent, of metallic oopper, and should the deposits prove persistent, might be profitably mined for treatment by a wet process. Several attempts have been made to work these deposits, hitherto, without success ; another trial, I understand, is to be made during this year ; it is to be hoped with better results. I give the following description of the locality from the Report of the Dept. of Mines, 1877 : " Mr. Patterson, in 1857, got a thirty years' lease of this locality, but then did no more than extract a sample of both qualities to send to England. In return he was advised that the nodular ore wafi the moat valuable and would command a ready sale ; but he let the property lie idle till 1866, when some six men were constantly employed during the summer, chic^fly in working out the north-west side of the river at a spot where the bank is steep and about 60 -*/./ AND MINERAL LANDS. 77 of at of et w le ir i M feet high. Shallow drifts and shafts were driven and sunk to prove the de- Soflit, but of the results I have no information. Nor that further work was one until 1876-77, when six months work of twelve men produced, accord- ing to the statement of Mr. Prendergast, the manager, some 36 caskd of ore. each averaging about 900 Iba. Subsequent work for two months yielded 6 more casks, averaging 800 lbs. each, or a total of 18^ tons, valued at New York at $120 per ton, " The excavations made, extended along the bank about 400 feet, and in laid over 200 feet, in length they measured nearly ^000 feet. " Acrosc; the river some work was also done, but as in 1866, it did not prove so remunerative, only one bed, and that small, containing noudules. *' On the west side the grey sandstone beds near the top of the bank, carry the nodules disseminated through them to a depth of about 4 feet, the princi- pal deposit being in a dark grey bed from 8 to 10 inches thick. Owing to the action of subeerial agents, the bed has a greenish caste, and the nodules are coated with carbonate. In composition both the mono and disulphide occur ; Mr. Louis, the analyst at Londonderry, was the first to detect the presence of covelline.* The nodules are on an average small, not larger than cherries, though some have been found weighing one and a half pounds. When I visited this locality the drifts had so fallen in that it was impossible to esti- mate the apparent extent of the deposit, but from what was to be seen, it appeared not improbable that the nodules were not equally disseminated throughout the bed in which they are found, but are collected together, as it were, at eddies or banks in the sandstone deposit. Below the grey beds, come beds of a reddish color, and below them, close to the river's edge, other grey beds in which are the remains of plants, the tissue of which has become filled with copper pjTites. " At Waugh's River, and at other places in the neighbourhood, copper ore thus associated has been found. It has been worked on Waugh's River about three-quarters of a mile from New Annan, and in 1877, some eight barrels of ore were collected, weighing about three tons and valued at 830 per ton. " Very similar ores occur in millstone grit, in Westmoreland County, N. B., and samples are reported by the Provincial Assayist to yield 15 per cent, of silver. In Kings County, at East Dalhousie, a lode of quartz, associated with granite in pre-carboniferous measures, has been sunk on during the past year to a depth of about 95 feet. The ores are v»treous and gray, sulphurets; and blue and green carbonates. Assays show the presence of silver up to 25 oz. per ton of 2000 Rs. At many points through the district strong indications of copper ore are found, and should the present prospecting show workable deposits, they would probably also receive attention. Mr. Poole, in his report on the Western Gold Fields, in 1862, men- tions finding copper pyrites in slates at Blandford Cove, Lunenburg Co., * Covelline 18 a sulphide of copper formed by removal of part of the copper in the vitreous ore ; he mineral in question held 64'11 per cent, of copper. 78 NOVA SCOTIA MINB8 Hillsboro Brook, Westfield Brook, Geyser's Hill, Jebogue Point, also a common mineral in the gold-bearing lodes of the Province. It is. The head waters of the East River of Pictou have yielded specimens of copper pyrites, with spathose iron gangue, but no attempts have been made to search for their source. In the vicinity of the Garden of Eden, several localities have been observed, holding veins of spar, up to several feet in thickness, with crystals of copper pyrites. The only deposits which have been tested to any extent are those of Antigonish County, where large sums of money have been spent, and a considerable tract of county proved to be cup- riferous. At Lochaber, on the property controlled by Messrs. McBean, Eraser, and others, of New Glasgow, the explorations so far as carried show a series of veins, cutting at oblique angles black and red shales and (juartzites, and thrown for a short distance 30° out of an east-and-west course by a dyke^ apparently a diorite containing talc and serpentine. The first vein met going east is about 2 feet wide. I have no details of its contents. The second vein, 80 feet distant, has been proved to a depth of 85 feet ; it varies in width from 5 feet 6 inches to 6 feet 3 inches, and holds about 20 per cent, of copper pyrites, evenly'^distributed in talcose slate, greenstone, and quartz, and micaceous iron ore. The third vein, 216 feet distant, 'n from l' foot 6 inches to 2 feet wide, and holds copper pyrites, with erubescite in bands, with quartz and talcose greenstone. The fourth vein, 130 feet distant, is about 5 feet wide, and carries about 10 pf r cent, of rich ore with much quartz. The fifth and sixth veins are respectively 50 and 1 50 feet further east ; they are about each 3 feet wide. The leads also contain large per-centages of ore, but have not yet been examined. In these last, the micaceous ore has been, to some extent, replaced by carbonate of iron, which is the chief gangue of the Poison's Lake ore. The sixth vein is gradually returning to its east-and-west course ; and, at a further distance of 300 yards, it has been opened again, and proved to be 4 feet 6 inches wide • and, nearly half a mile to the east, on the strike of the vein, two small veins have been found, holding very good ore, and large boulders proving, the passage of the larg3r veins. The quality of the Lochaber ore is unusually good ; the chief variety met is copper pyrites, with a small admixture of carbonate of copper and erubescite. The gangue at Lochaber is chiefly micaceous iron ore, with a little spathic ore ; at Poison's Lake, exclusively the latter.

The course of the cupriferous band has been traced, by surface- indications, from thi% point, about four miles, to Poison's Lake where, during the past summer, a very fine vein of spathic ore, holding copper pyrites, and a little iron pyrites, was traced for several' hundred feet through dark blue and olive slates. Its width varied from 6 to 1 1 feet ; and its cours(,y was about N. 70° W. (astr.). Dr. Dawson gives the average of copper in this ore at 10-8 per cent. The explorations were carried on by the parties already mentioned, and by Mr. W. Ross, of Pictou. The following notes are by Dr. Harrington (G. S. R. 1876-77, p. 476). The first sample, taken at a considerable depth from the surface, where the vein was 11 feet thick, yielded 11-7 of copper, but no silver. The second samplo was from the surface, and consisted of copper pyrites, pale iron pyrites, hydrated peroxide of iron, and rock matter ; it yielded 5-67 per cent of copper, and, I believe, no silver. On the Salmon River, the Primrose property shows a small vein, which was tested to some extent a few years ago, and contains very rich copper ore.

S., the ore contained from 37 to 39 per cent, of copper, and waa composed of coppt^r pyrites and erubescjte. The age of the strata holding these deposits is not yet definitely known, as no systematic geological survey has been made of this part of the Province. The sandstones, shales, limestones, and bedded diorites, et/C., very strongly resemble the Eastern Townships copper-bearing rocks. In Cape Breton, a large number of places are noted in the reports of Mr. Fletcher, of the Geological Survey, as holding copper ores, as traces and deposits possibly of workable extent. Thus he mentions the metal as occurring in traces as copper pyrites in the crystalline rocks of Ben- acadie, the White Granite Hills ; in quartz veins in Ae Lower Silurian felsites of Gillis' Brook, as green carbonate ; in Lower Carboniferous Conglomerates, Spruce Brook, Bras d'Or. In his report 1876-77, he says : " Mention has already been made of a number of places shewing traces of copper glance, oxydised to carbonate, impregnating a conglo- merate often at its contact with an overlying bed of limestone, as at Irish Cove, East Bay, Washaback, Middle and North Rivers." Three asr ys of samples from the Washaback Conglomerate, near Crow Point, are said to have yielded Dr. Hayes : 1. 5 dwts. of gold per ton, 2. 3-10 of copper, and 19 dwts. 4 grs. of gold per ton. 3. 16 dwts. 8 ^ of gold, and 6 dwts. 12 grs. of silver per ton. Although, in some cases, these deposits may be the remains of plants replaced by metallic ores, as pointed out by Prof. Hynd, in a report on the district, the mineral often forms the matrix of the conglomerate. Yellow copper pyrites occurs on the farm of Angus McDonald, on the French Boad, near ( cbarus, as nodules and layers in a compact felsite, occupying a considerable tract of country. Copper pyrites occurs at Eagle Head, in Gabaras Bay, in a belt of laminated quartz, some 25 feet thick, intermixed with soft feld- spathic rock. The quartz layers are of various thicknesses, and carry the ore in irregular quantities. Associated with the band, is a whitish green soapstone with arsenical pyrites, bismuth glance, iron pyrites, molybdenite, and traces of gold. The copper is also met in a light coloured felsite, containing vugs lined with crystals of quartz, and appears to be generally distributed through the neighboring felsites. Shafts have been sunk at the Eagle Head and French Road deposits by Mr. F. AKI) MINERAL LANDS. 81 Wlershausen ; and it is understood that well-detined *nd promising ▼eins have been found. On the Gillis Lake Road, an excavation made by Mr, J. McKenzie, of Sydney, disclosed a soft, sectile, soapy rock, impregnated with calcspar, tlnised with a talcose Iiematite, and holding iron and copper pyrites and freen carbonate, in a compact gray and pink felsite. Similar ores occur at other places, as at Boisdale and Goxheath Hills, but have not yet been tested sufficiently to allow of estimates of their value. At Cheticamp, about 15 years ago, a good deal of work was done on a vein 5 inches thick, holding chrysocoUa, blue and green carbonates and grey ores, but the results were presumably unsatisfactory. During the . fall of 1879 fresh discoveries of a number of small veins holding copper pyrites were reported from this locality ; but owing to the prevailing neglect displayed in making returns by those hdfding licenses from the crown, I cfitfi give no details. At numerous other points, especially in the vicinity of Cape North, the northern part of the Island, specimens of copper ore are found, but no work has been done to test their value. Although in this Province no copper mines have yet been systemati- cally worked, and many of the deposits have not repaid the prospectors' labour, the indications are so wide spreaxi, and many parts so well adapted, geologically speaking, for workable copper lodes, t)iat we may reasonably expect to see it form a regular article of export before many years. And so long as so many promising indications are met, there will always be an inducement to test their adaptability for working. In this connection, the presence in the province of the equivalents of the well-known copper bearing strata of Cambrian (?) age, as found in the Province of Quebec, is important. A full description of these strata, their associates, and the manner of occurrence of the ores, will be found in Sir W. Logan's "Geology of Canada," 1863 ; and they are noticed in subsequent reports of the Survey. This is another of the reasons that could be brought forward as showing the importance of a complete Geological Survey of the Province. The determination and mapping of the great rock series, which hold their peculiar minerals and ores, is a work that every country is now recognizing as due to those who venture their time and money in the development of its mineral resources. The present tariff imposes a duty of 30 per cent, on manufactures of copper, and of 10 per cent, pn the metal. The effect of this has been 82 krOVA SCOTIA MINES seen in the impetus given to the copper miners and smelters of Quebec ; and it would prove a serviceable assistance to any who were disposed to enter upon such operations in this Province. In this connection, it may be interesting to give the following report of the last ore ticketing of the year 1879, at Swansea : 2109 tons of ore were sold, realising l'2,lQil. 18s. The particulars of the sale were — Average standard for 9 per cent, produce, 9U. Is. lOd. ; average produce, 8f ; average price per ton, '5Z. 15s. 4d. ; quantity of fine copper, 186 tons 15 J cwts.

It occurs as a very common acces- sory mineral, with other sulphides, in the auriferous lodes of the Atlantic . coast. In this connection it sometimes holds silver up to 6 or 8 ozs. to the ton of ore. Nowhere, however, does it occur in these veins in quantity sufficient to make it valuable by itself. In the limestonl&s of the Lower Carboniferous, it frequently occurs as disseminated crystqjs, as at Springville and West River, Pictou County, in Cumberland and other places. At Gay's River, Halifax County, it is found in this connection in quantities which have warranted somewhal extensi"" expenditures. The bed rock consists of layers of limestone lying horizontally on the unoonformable Silurian slate, and are supposed to be on the same range as the auriferous conglomerate already noticed in this district. The Cklena is found in small crystals scattered through the beds, ag- gr^ted about small cavities, and occasionally occurs in small strings. The discovery was first made by the farmers burning the stone for lime, but the explorations continued since that time have not succeeded in finding the ore sufficiently concentrated for working. rim AND MINERAL LANDS. 83 Wherever opened, the limestone seems equally charged with Galena at all points in the beds, hundreds of feet apart. The deposit is acces- sible by simple quarrying, and an abundant supply could b€ calculated on were any process known capable of treating such a small per centage of ore. Hand specimens can be found giving 17 per cent., but sorting is required to give an average of three per cent. Assays have shown silver to be present in quantities varying from 3 to 12 ounces to the ton of lead. At Pembroke, in Colchester County, in limestones of similar age, ex- tending over several miles of country. Galena is found everywhere in veins 2 or 3 inches wide and in disseminated crystals. Some prospecting of an irregular character has been done, but little is really known of the deposit. As the ore is more concentrated, this locality offers a better prospect of success than Gay's River. In this connection it is interesting to recall the fact that in England and other countries extensive mines of lead ore have been opened up in limestones of the same age as those noticed above. This fact lends an importance to the presence of such deposits in this Province ; although it must be borne in mind that our lifoestones are not usually as massive as those of Engli^d. A sample of Galena from Musquodoboit, locality not named, gave me on assay 73"56 per cent, of lead. In Guysborough County, at Caledonia, a vein of Galena, varying in thickness from 1 to 6 inches, was recently tested. Some 16 tons were shipped, but work was stepped, for the ore, although excellent, was not present in quantity large enough to pay the cost of prospecting.

S4 NOTA SCOTU IHKBS Doubtless the district contains other and larger veins carrying Galena, and judging by the samples shown, it offers a fair field to the prospector. Similar indications of Galena are found in limestones near Sydney and Arichat ; and at Port Hood'it has been found in a vein in sand- stones between two seams of coal, similarly to the Galena at the Joggins, which occurred in a fault. The latter on analysis yielded but two traces of silver. On the Salmon River Road, near the L'Ardoise Road, Galena and crystals of Calcspar occur in a dark grey fossiliferous limestone. Bad- deck, McKenzie, Fishpond Rivers, Guysborough, and other localities are known to yield promising samples of the ore. During 1879 discoveries of Galena, carrying in some cases 100 ounces of silver to the ton, were reported from the head waters of the Gold and LaHave Rivers, but no work has yet been done to allow of any definite statements. Mr. Fletcher, in the G. S. R. 1876-77, p. 451, states : The value of the quartz veins of the schistose rocks of Burnt and Boulaceet Harbors was tested some years ago by Mr. A. Cameron, of Baddeck. At the former place a number of irregular ferriginous quartz veins, the largest about 15 inches thick, hold traces of argentiferous silver, copper and iron pyrites. An analysis of Dr. Hayes, of a sample from one of the veins showed it to contain 39 oz. 10 dwt. 12 grs. of silver to the ton. At the latter place a vein, from one to four inches ^hick, cuts the strike of the rocks nearly at right angles. In this was found a large pocket of Galena, holding gold, sulphide of silver, copper and iron pyrites, and producing 18 oz. 9 dwts. 3 grs. of gold, and 97 oz. 10 dwts. 14 grn. silver to the ton. A considerable per-centage of copper pyrites and specular ore is scattered through the hornblendic or quartzose rocks holding the vein. Between the Upper Settlement of North River and the road from McDonald's Pond to St. Anne's are numerous small quartz veins holding Galena, copper and iron pyrites, and black, honey-colored blende. They appear to form fissures in the red syenite, and to run out or merge gradually into it. On McDonald's farm, one mile north of the bridge over North River, at the head of tide water, a similar deposit was tested a few years ago. An ill-defined vein, varying in thickness from 3 to 12 inches, composed of quartz carrying galena, copper pyrites and blende, occurs in a greenish, jointed, prophyritic felsite. The junction Avith the ha^iging wall was well marked, but the lower and most productive portion of the ▲XO iriKBKAL LANDS. w I" lode adheres strongly to the foot-wall. A sample of 900 lbs. of the oro yielded, in Boston, 155 lbs. of pig lead and 2'96 oz. of silver to the ton of ore. This district has been represented, by practical miners, a» worthy of an extended search, as promising samples of ore have been found at several places in the vicinity. Silver Ores. — In this connection it may be mentioned that Mr. Campbell reported discoveries of native silver and its carbonate in veins of soft spar on the McKenzie Rivek', of Inverness Co., Cape Breton, and Mr. Barnes also reported finding it very abundantly in the drift of the same stream. But since the date of their reports, nearly 20 years ago, no further discoveries h'^/e been reported. The district lying north of Bras d'Or Lake has been seldom traversed by the mining engineer, and still remains an interesting lone land. From the numerous reports of copper, lead, silver and gold found in the streams running from its high lands, it would afford a promising field to the prospector. From the preceding notes it will be seen that while there are favorable indications of the presence of silver-lead ores, almost no work has Ixen done in the attempt to prove their value. The lower carboniferoufi limestones in thiB Province cover a large extent of ground, and may reasonably be expected to afford workable deposits at favorable points — for instance, in proximity to intrusive rocks of later date, or wherever they appear to have been previously in a position favorable to the concentration and deposition of such ores by aqueous agencies. The geology of Cornwall is duplicated in parts of this Province, and the indications are not wanting of a similar store of mineral wealth. It must be remembered that our woods and snow-laden winters prove an obstacle to the industry of the prospector, and th«,t few among our farmers and fishermen are acquainted with the appearance and form of even the more common ores. I have several times reueived samples of lead ore, said to have been found in the centre of thei western part of the Province, but I am unable to give any derails of the localities. These indications aire borne out by the discoveries, already alluded to, said to have been made during the past summer. Further develop- ments will prove interesting, for geologically speaking, the localities of the discoveries have been well chosen. ANTIMONY, MOLYBDENUM, NICKEL AND COBALT, BLENDE, TIN. Antimony . — This ore is as yet unknown in this Province, except as reported to have 'been noticed in auriferous quartz lodes. In Ne^ 86 ^ NOVA SCOTIA MINES Bruufiwick, the sulphide of this metal has been found at several places, and I believe a considerable quantity has been exported at various times. As the Silurian strata holding this on; in the neighboring Province are also believed to form part of the pre-car)>oniferous systems of Nova Scotia, a reasonable expectation may be held out of their occurrence here also. For the information of those who have not seen the ores of this metal, or are not familiar with its appearance, I give the following description from Danas' Mineralogy of the sulphide, the ore from which the antimony of commerce is obtained : Color and powder, lead grey j lustre shining, and liable to tarnish. Brittle, but sometimes the thin layers are a little flexible. Ggnerally massive, or semi-fibrous. About four and a half times as heavy as water. About the same hardness as white gypsum or rock salt. It fuses readily in the flame of a candle. Antimony is extensively used in type metal, Britanria ware, phar- maceutical preparations, etc. Molybdenum. — The sulphide of this metal is found at several places in the Province, as at Gabarus and Louisburg, in Cape Breton, whAre it occurs in small quantities, over a large extent of couhtry. Hammond's Plains, Lower Musquodoboit, and Lunenburg are also said to have yielded specimens. I am not aware that there is any great demand for it, as, although it can be utilised for several processes in dyeing and coloring, its supply in regular quantities cannot be depended on. Nickel and Cobalt. — These ores are very common in the Province, but are seldom found in mx>re than traces. Cobalt occurs in mispickel, at Montagu, and I have observed it in the same mineral at Cochran's Hill, Guysborough Co.. Dr. Dawson also shows its presence in copper ore from Carribou, Pictou Co. An analysis of pyrite, from Londonderry Iron Mines, G. S. R. 1874-5, p. 316, gave, when dried at 100° 0. : Iron .' 46193 Nictel -144 Cobalt -SIS Copper ^ . . . . trace Sulphur 52-434 Silica -523 Alumina '513 Ferrous oxide .'.

The mines of Tilt Cove at one time yielded large quantities of nickel pyrites (millerite), which is reported to have frequently brought 8675 a ton in England, where the price per pound is now about fifty cents. This ore, I believe, has never been observed in this Province. Nickel is best known in the arts as an alloy, and is extensively used for plating. Cobalt is chiefly used for painting porcelain, pottery, etc. The mineral retwms of England gave 98-9 tons of cobalt as the produce of the King- dom in 1878. ^iiic as yet has been observed in Nova Scotia only, as an accessory mineral in auriferous quartz lodes. Tin. — Messrs. Barnes & Campbell reported finding tinstone at Tan- gier and Shelburne, associated with decomposed granite debris. I have had specimens brought to me from the neighbourhood of Tangier and Country Harbor. Should this ore prove abundant in the Province, it would form a most valuable adjunct to our mineral resources. As tinstone is not readily recognized, and specimens have seldom been seen here, I venture to give the fallowing description, which may be useful : But one ore of tin has &ny commercial value — the oxide, containing when pure, 78 per cent, of the metal. It occurs in modified square prisms, massive or in grains. Its color is brown or black, with adamantine lustre when in crystals, and nearly transparent to opaque. Its powder is pale grey to brownish. It can be scratched slightly by quartz, and gives a light brown or reddish powder, and is from 6 to 7 times as heavy as water. It bears some resemblance to zinc blende (Black Jack), but is harder. Stream tin is the name given to the ore when found in alluvial washings ; it is also called wood tin when in a fibrous form. The ore occurs in the crystalline rocks, granite, gneiss, and mica slate. In Cornwall, the lodes generally run east and west, but are irregular, sometimes crossing one another, or spreading into a network of small veins, or in a flat bed, or in fine crystals disseminated through the rock. The veins are considered worth working when but three inches wide. I * Notts of rynhctitM conUininc nickel, H.

MINERAL MANURES. — GYPSUM. — PH0SPHATB8. 9 Gypsum. — This mineral is known in the Province under two foruts, as soft gypsum, containing : Lime 32-55 Sulphuric Acid 46-51 Water 20-94 and as hard gypsum, or anhydrite,^hich consists of 41 per cent, of Mme and 59 per cent, of sulphuric acid. The mineral is found in ex- tensive beds, varying in thickness from a few inches up to 120 feet, and also occurs disseniinated in fine grainc in the shales, marls and lime- stones which are usually associated with it. In the Maritime Provinces it tKscurs in the Lower or Marine Carboniferous formation, already re- ferred to in connection with the manganese ores, and where the lime- stones appear it is usually at no great distance. Its appearance is so well known, and it is so widely scattered through the northern and eastern part of the Province, that a catalogue of its exposures would be an endless task and serve no useful purpose. The chief localities yielding it are Windsor, Cheverie, Maitland, Walton, Hantsport, Wal- lace, Antigonish, Mabou, Judique, Port Hood, Port Hawkesbury, and many places on the Bras d'Or Lake, and in Pictou County. So ikr as knoAvn, it occurs at no fixed horizon in the Marine Lime- stone formation ; being found at Sydney, a few feet below the :^ill8tone Grit, and in Pictou County almost in contact with Silurian strata. Among the minerals found in the gypsum may be mentioned glauber salt, common salt, calcspar, magnesium carbonate, airagonite, carbonate and oxide of iron, silipa, and free sulphur. The late Dr. How also dis- covered the following interesting minerals, which, if found in quantity, would prove very valuable. They are compounds of borax occurring in 94 NOVA SCOTIA MIXES the gypsum and anhydrite of the Windsor district, and are presented in crystals and nodules up to 2 in. in diameter ; in some cases forming a considerable per centage of the rock. The nodulee are sometimes pearly white, compact and hard ; in other specimens they are made up of accicular tufts of prismatic crystals, colorless and translucent. The following table shows the composition of these minerals, and also of another discovered" by the same gentleman at a later date, and appa- rently formed by partial replacement of the Ulexite by Selenite. The Ulexite is a very pure form of the Peruvian borate "Tiza," which is found, I believe, only in these two countries. It has been largely exported into England and the United States from Peru, ^r the manufacture of borax and for use in glazing operations. Should these deposits be found to occur in quantity, it would form a valuable export, and niaterially aid the out-put of the associated gypsum.

In Autigonish it occurs on St. George's C*y,as a crystalline cliflf 200 feet high, and similar exposures are met at Plaster Cove, Mabou, and many places on the Bras d'Or. This scale of exposure, and the frequent proximity of the deposits to good shipping places, has materially aided its output. The facilities for quarrying have allowed its extraction at rates varying from 45c. to 65c. a ton, and this low price can be maintained for many years to come. The anhydrite is found as lenticular masses of every size imbedded in the gypsum, and as beds underlying and alternating with it^ The soft gypsum, however, is the one chiefly quarried. It has been largely exported in the raw form to the United States, where it is ground for a fertiliser, or boiled and ground f^r finishing houses, cor- nices, mouldings, etc., according to its pureness and color. It is said to be a suitable dressing for tobacco and cotton lands, and large quantities are mined for this purpose in Saltville, Virginia. AND MINERAL LAKL»S. 95 Ontario annually imports from the States about $20,000 worth of ground Nova Scotia gypsum for top-dressing, in additioii to that fur- nished by the gypsum beds of the Onondaga period, iu the vicinity of the Grand River. As a prohibitive duty is imposed on ground gypsum imported into the States, we are][unable to pursue the manufacture of the plaster for their markets, but are obliged to furnish them with the raw material only. Thus New Brunswick sends o»ly about $2,000 of ground gypsum to the United States, and none is exported by No^ Scotia. This is very much to be regretted, as the value of say 25,000 tons of ground gypsum would be about $113,000, or more than the value of an export of five times that amount of the raw material. At Hillsborough, in New Brunswick, there is a large plaster mill which supplies the local demands with a very superior article. At this establishment a 40 horse power engine furnishes the power necessary for driving the stones, working pans, making barrels, etc. Four cauldrons are used, each holding 18,000 BE>8. ; in the course of the day, each will yield three charges. At present this mill is 'vorking at only one-fifth of its capacity. From information, kindly furnished by the manager, it appears that the cost of the calcined gypsum, is about 90 cts. per barrel of 300 lbs {including barrel and paper.) This cost would be materially reduced if the mill were working to its full capacity. The Nova Scotia plaster sells at $1*86, and the Hillsborough at 2*00 a barrel in Halifax. A consider- able quantity of gypsum is prepared for agricultural purposes in the Province, although, as the farming districts are chiefly in the carboni- ferous measures, nature has already supplied it in many places. There are a number of small local mills where the gypsum is ground for architectural purposes, but no account can be got of the amounts thus utilised. Last year Walton shipped 50 tons of ground gypsum, valued at $225. It may be remarked that at many points in the Province, as Anti- gonish and Windsor, the transparent, pure variety of gypsum, com- monly called isinglass, and known to the mineralogist as Selenite, can be procured in large quantity, and also almost chemically pure, massive, white gypsura. These qualities are specially utilised for cornices and centre-pieces, and when Utey can be reguiMrly obtained, furnish the best material for the more common applications of the nfkanufactured article. jr B '< if 96 VOTA SCOTIA MIKB8 The anhydrite has hitherto been utilised for few purposes ; it is tjuite as well adapted for agricultural use as the soft gypsum, but as it requires stamping for its pulverisation, its cost is thereby increased over that of the other, which can be readily ground. It has been used for foundation walls, etc., but is not durable enough for any permanent building purposes. It takes a good polish, and has several times been cut for mantels, table tops, etc., but has not come into general use, as it is believed not t< stand expot;ure long enough to supplant marble. The following statistics will show the extent of the trade which has been carried on for many years — Quantity and value of gypsum exported from Nova Scotia : " Tons.

The amount exported from Nova Scotia during the year 1879 was 95,126 tons, valued at $74,923. The total exports from Nova Scotia since 1854 are, so far as my in- formation goes, about 2,300,000, valued at about $1,900,000. The total amount shipped from Windsor since 1833 is approximately 2,544,376 long tons, valued at about $2,000,000. Mr. Hunt gives the quan- tity raised in England in 1878 at 74,908 tons, valued at $109,438. Were any revision of our present tarift' arrangements with the United States carried out, and the duty on the manufactured article taken ofl*, the plaster trade would assume important dimensions in Hants County, and the export would be correspondingly increased by the reduced prices. Phosphatic Nodules.— Mr. H. Fletcher, G. S. R. 1876-7, p. 433, mentions finding in the Lower Silurian Limestones of Mackintosh Brook, Cape Breton, layers of phosphatic nodules. Similar nodules are not uncommon in Quebec, and have been observed at Arisaig and in Colchester County, samples from the River Quelle having yielded upwards of 40 per cent, of phosphate of lime. The Capfe Breton deposits are not •ensidered of economic value ; but were they in any quantity, a valuable fertiliser could be manufactured for local use, '""""'*'*' ■' ■■ ui AJfD MINERAL LANDS. 97 CHAPTER V. MINERAL PIGMENTS. — BARYTE8. — OCHRES. e B 11 I, 1 e n s it e Paivis, — This name may be applied to two classes of mineral aggre- gations found in this Province. The first consists essentially of iron ores, composed of hydrated peroxide of iron, with manganese, silica, alumina, and water of hydration. They are frequently, as far as their composition goes, valuable ores of iron, being originally carbonates of lime, iron, and magnesia, in varying proportions, and having lost, by infiltration, the lime, phosphates, and the sulphur compounds, and much of the magnesia. But, owing to their large per-centages of moisture, and friable nature, they cannot be utilised for the blast furnace, unless first made into briquett.es. Good examples of these classes of paints are to be met at the Londonderry Iron, Mines, where they appear to have been derived from the Ankerite and Sideroplesite forming the vein stone. The following analyses show the original and present composition of these minerals : COMPOSITtOM. ANEBRITB8. OCHRBS. Yellow. BrowD. Yellow. Red. Iron — Carbonate Lime — Carbonate ...

The red colors produced by burning the ochres are Tiiodified to purples by manganeiie, and" to browns and greys by mixtures of white clay and other impurities. Similar ochres occur in Antigonish and Pictou Counties in connection with the specular ore veins, and at Chester and numerous H i 08 NOVA SCOTIA MINES other points. At Chester the ochres are formed by the oxidation and hydration of the limestone a of the Lower Carboniferous age, and frequent- ly contain large quantities of manganese, aflfording purplish paints which were formerly manufactured to a considerable e xtent, and are still used locally. The other classes of ochres have beeii formed by water depositing in beds of earth, marl, etc., oxides of iron, mangane'^e, etc. Such deposits occur at Folly Mountain, Onslow, Kentville, Oomwallis, Poison's Lake, Chezzetcook, Lunenburg, and many places in Caps Breton. Aq already mentioned, these last-named ochres pass insensibly into bog iron ores and wad manganese, accordingly as the oxide of iron or manganese predominates. Considerable quantities of ochres are prepared in the Province of Quebec, but the imports and exports of this article are small. The quantity of ochre raised in England during the year 1878 was 2,903 tons, chiefly from Anglesea, and worth, on an average, £1 2s. 6d. per ton of 2,240 lbs. Messrs. Brandram Bros., of Botherhithe, S. E., near London, write : *' Scarcely any ochres are available as pigments until they have been very finely cleansed and levigated, and then very much depends upon their staining power as well as the richness of their color, and this is in some cases more valuable when they have been carefully and thoroughly burned, as with the Italian Terra de Sienna, Turkey Umber, and others known as metallic oxides. The ochres most in demand here are from the mines in Wales, and also from those in Auzerre, in France, and they vary in value from £2 lOs. to .£12 per ton of 2240 lbs. The French ochres are prepared and levigated before they are sent to this country, and are mostly in an impalpable powder. Those from Italy are in lumps, as is also a celebrated yellow ochre, known as Oxford stone ochre, found in Oxfordshire. The writer remembers to have seen some very fins ochres in Nova Scotia in 1876, but at that time no care or trouble had been taken in their preparation, and he is of opinion that it would be useless to send them to Europe until this had been done." Marytei. — ^This mineral, generally known as "heavy spar," is fre- quently met in this Province. It is confined to no particular horizon in the geological sequence, but occurs in the Carboniferous, and all the older strata. It is extensively used as an adulterant for paints and enamels, etc. In England the amount raised in 1878 is put down at 21,715 tons, valued at about X2 1,000. The mineral sells in proportion to its free- AND MINERAL LANDS. 99 dom from iron, copper and other ores, imparting a color to the ground material. Othpr impurities, such as bJIica, gypsum, etc., are not so injurious. • At Five Islands, dolchester County, it occurs in irregular pockets in the Lower Carboniferous. The mineral is frequently in the beautiful characteristic tabular crystals, and is associated with calcspar and copper pyrites. About 1000 tons have been exported to the United States, and a considerable quantity manufactured for home use. Some years ago a few hundred tons were mined from veins in Lower Carboniferous sandstones and shales on the Stewiacke River, near Brookfield. During the ' st few years this mineral has been intermittently mined at River John, where it occurs in veins, in measures said to be of Lower Carboniferous age. The quantity exported from River John in 1879 amounted to 480 tons, valued at $2,400. It also occurs associated with limpnite at the mouth of the Shubenacadie River and Clifton, and at Brooklield, near the iron ores of that locality. Among other localities may be mentioned the Lower Carboniferous of the Avon, Musquodoboit and Wallace Rivers, and Greenville, Cumberland County. It is fre- quently found with the manganese ores ot Hants and Colchester; Counties. I have also seen samples from Antigonish County, Whyhogo. mah, Cheticamp, Loch Lomond, St. Annes and other Cape Breton localities. Although occurring in numerous places, it is the exception to find the ore holding only traces of impurity. 100 MOTA SCOTU MIKES I, J-'- CHAPTER VI. SALT. — MINERAL WATERS. Salt. — This mineral in many countries is intimately connected with gypsums and marls, in rocks of various ages. Salt is found in crystals in many of our gypsum quarries, and springs holding large quantities of it issue from their neighborhood. As yet, however, no bed of salt has been found in this Province. The import- ahce of a discovery of such deposits may be gathered from the fact that during the year 1877-8, Nova Scotia imported for home consumption, 930,114 bushels of salt, valued at $99,392, and last year's importation was valued at $105,207. England made in 1878 1,500,000 tons of white salt from brine, and 182,930 tons of rock salt. No systematic test has ever yet been made of our gypsums and marls at a proper depth from the surface, and the subject is one worthy of serious attention. In Goderich, Ontario, extensive beds of rock salt were discovered in 1866, in deposits, in many points identical with our Marine Limestone formation, but of much greater age. An interesting account of these discoveries will be found in the G. S. R., 1876-7, and else- where. From Mr. Smith's Report, 1874-5, it appears that in 1873, 461,576 barrels of salt were made, and valued at $436,217. In 1876-7, Canada exported 789,599 bushels, valued at $82,323. In Nova Scotia, salt has been made at varfous times from brine springs, and in some cases a superior quality was produced, but at present very little is being done. Among the various springs, the best known are those of Renfrew, Walton, Salt Springs, and Irish Mountain, Pictou County, Sutherland's River, Antigonish, Ohio, Baddeck, Why- hogomah, River Philip and Black Brook, Cumberland County. At the last named locality, salt is at present manufactured by the Messrs. Gil- AND MINRRAL LAKD8. 101 roy, and is suitable for house »;8o.

There are numerous mineral springs in Nova Scotia, as would be^ expected from the variety of its geological formations, and the deep- seated disturbances which have brought them to the surface. Many of these springs are locally believed to exercise healing or restorative powers, and in some cases it appears justly so. Others again owe their fame merely to an abnormal taste, caused by common salts not present in quantities large enough to exert medicinal effects. The late Dr. How examined several of these waters. The results of his labors, and*a few analyses! by the writer and the chemist of the Geological Survey, com- '''prise all that is positively known about them. In the event of a Geological Survey being extended over the Province,' these springs merit a careful examination, as the presence of mineral waters of undoubted excellence has frequently done much to attract tourists and visitors, and produde thereby other benefits equally important, although, perhaps, not 80 conspicuous. Among these springs, that of Wilmot, some fifty years ago, had a considerable reputation, but is novf seldom visited. On' the property of Mr. Bowman, near Windsor, is a spring rising from the Lower Carboniferous limestones and gypsums, and containing, as would be expected, an unusually large amount of Sulphate of Gypsum. An Alkaline spring is known near Chester, Lunenburg County. On II V ^ 102 NOVA SCOTIA MINM the Salmon River, in Cape Breton, another spring is known, and reported to have effected cures in rheumatic and asthmatic complaints. The water risen in syenitic rocks, considered to bo of Laurentian age. Cheticamp, Mabou, and Grand Anse are other localities yielding mineral waters. Gair Loch, Irish Mountain, Sutherland's River, and Salt Springs are localities in Pictou County, where mineral waters of local repute are knovm. Earltown, Shelbume, Renfrew, and several other places are also noted for mineral springs, said to be useful in many disorders. COMPOUTION. Iron Phosphoric Acid Carbonate of Xdme " Magnesia.

MATERIALS APPLICABLE TO BUILDIKO PURPOSES. — FREESTONES. — GRAKITB, ^ ETC. — FLAGS AND SLATES. — CLAY. — LIMESTONES. — MARBLES — CEMENTS. Building Stones. — The building stones of Nova Scotia are chiefly sandstones and granites. The various grades of the former are supplied almost entirely from the Upper Goal Measures. We accordingly find the quarries in the Oounties of Pictou and Cumberland, and parts of Colchester and Hants. In Pictou, large quarries wore in operation some years ago, at the head of Pictou Harbor, and shipped annually about 5000 tons. During the last few years the export trade has been carried on chiefly by Messrs. Hogg «k McKeen, who supply an article of first-class quality. Other quarries have been opened at Glenfallock and Middle River. A considerable quantity of stone for the use of the Eastern Counties Railway was quarried at Merigomish Harbor. Every harbor and river from Pictou to Amherst affords building stones, frequently of good quality, as at Wallace and Tatmagouche. , Samples were sent to the Philadelphia ExhiBition from a ;uarry at Wallace, situated about 150 feet al>ove high water mark, and only 600 yards from a good harbor. The beds are horizontal, and for the first fifteen feet from the surface, vary in thickness from four inches to two feet. Below this there is a massive bed which, according to Mr. Heustis, is from three to eight feet thick. It is divided into rectangular masses by joints from six to fourteen feet apart, which greatly facilitates the quarrying. The cost of the stone, delivered on board vessels in the harbor, is from forty to sixty cents per cubic foot. At the Joggins, Minudie, and River Philip, valuable deposits have been opened. Passing to the Basin of Minas : Cornwallis, Johnston's Brook, Horton, Falmouth, Kennetcook and Old Bams are known to contain material adapted for building purposes. AND MINERAL LANDS. 105 About half of the stone used in the St. Peter's Canal was from tho south-east side of Boularderie Island and the vicinity of Kelly's Cove. The Boularderie quarry was abandoned, owing to the heavy capping. There was also much broken stone In the Kelly Gove quarry ; and great part of th^ material used was from boulders. The locks were finally finished with stone from Wallace, as the engineer in charge did not succeed in finding suitable material on the Bn^s d'Or Lake. The reports of the Mines Department give the shipments of freestone for the years 1873-9, at 45,814 tons ; the value varying from 82 to $20 per ton. Syenites, Porphyrvi and Granitei. — Granite is very abundant in the older rocks of the Province. Amo. g localities which have furnished it for building purposes, may be mentioned Shelburne, Queens and Lunenburg Counties. It also occurs at Aspotogcn and A-arious points thence to Halifax. As already mentioned, in describing the Gold fields, it runs almost continuously from Halifax to Windsor, and thence westward. It occurs again at Waverley, and runs through Musquodo- boit, Jeddore, Ship Harbor, Sherbrooke, and Country Harbor to Canso. It occurs in'and at the head waters of many of tho Eastern Rivers, and is estimated to cover a large area of the Atlantic district. It has, how- ever, been quarried only at points accessible to shipp ig. At Halifax, it has been used a good deal about Xhe fortifications, and a number of houses have been constructed of it, its cost, rough, being from $2.25 to $4.00 a ton. In the Cobequids, there are masses of flesh and red colored Syenite, which have afforded very handsome polished samples ; but, as yet, have not been worked for construction. Prophyries and Syenites occur in various parts of Cape Breton, but liheir economic value has not been tested. The following localities may be mentior. ed — St. Ann's, Boisdale, and Coxheath. The crystalline diorites of Louisburg were used by the French in building their fortifications. Limestones. — This material has not been used to any extent in Nova Scotia, for building purposes, although it is frequently found to stand exposure well, and to be readily quarried. Among localities yielding it, may be mentioned the Shubenacadie River, Kennetcook, Lower Horton, Thompson Station ; Glengarry and Spriugville, Pictou County. Stones from a quarry here, retain, after an exposure of forty yeafs, every trace of the chisel or pick. The marbles will be noticed further on. As before mentioned, the anhydrio or hard gypsum has been used to i 106 NOVA SCOTIA UINF'! a small extent for walls, foundations, etc. A flaggy arenaceous schist, known as iron stone, was extensively used some years ago, for warfr. houses and walls in Halifax. Many of the metamorphic sandstones of the Atlantic coast would furnish a most durable and pleasing building material. At present the supply of wood for building purposes is so plentiful, that brick or stone houses are the exception. Even public buildings, churches, halls, etc., are almost always of wood; but as this material becomes more expensive, the labor of the quarrymen will succeed that of the lumbermen, and our towns become something better than wooden shells, blackened by smoke. Flags and Slates. — A small amount of flagstone has been quarried on the North West Arm of Halifax Harbor, and at Beaver Bank. Slates V. ere quarried to a small extent at Rawdon, and various places in Hants County, and the quality and quantity are equal to any demand. Dalhousie Mountain and West River, Pictou, are said to have good slate beds, and it is also reported from the South Mountain, Digby, and Yarmouiu Coimties. At the Provincial Exhibition of 1879, slates were shown from Sackville, River John and Upper Stewiacke, which, although in the rough, were of good material. The demand for roofing slates will become general in the Province in a few years, as their superiority over the shingles in ordinary use becomes apparent. Brick Cl^y. — These clays are found in many places, presenting an .unlimited supply of raw material to the brick maker. As yet, brick is but little used in the Province, although when well made and used ae- cording to proper designs, it makes the best building material for this climate. The best known clay fields are those of Shubenacadie, along the line of the Intercolonial Railway, and many poiixts in the carboni- fei^us districts of Colchester, Pictou, Cumberland and Antigonish. The present selling price of brick in Halifax is, for best at Depot, $8.00 per M ; Chettezcook $6.00 per M on wharf. The amount of bnck imported into Canada during 1876-7 was 2,218 M, valued at $10,823. During 1877-8, it was 1,981 M, valued at $8,213. In 1877-8, Nova Scotia imported 125 M, valued at $768. The present annual make of brick in Nova Scotia cannot be readily estimated, but may be approximated at 10,000 M. At the Provincial Exhibition of 1879 samples of brick of good quality we J exhibited by Messrs. Smith & Kaye, Miller and others. AND UINERAL LANDS. 107 It may be remarked that very many of our home-made brick are carelessly made. Proper attention is not always given to the weathering, picking out of pebbles of limestone, etc., and the clay is seldom ground or otherwise divided, and too frequently the proper admixtures of mild earths are not attended to. The life of Nova Scotia bricks is generally far shorter than it should be, as when properly made it is one of the most durable materials known to the architect. The bricks made by the French at Mira. and extensively used in the building of Louisburg, were carefully prepared, and remain at the present day as sound as when they came from the kiln. Limestones. — In Nova Scotia the limestones are confined practically to the Lower Carboniferous, and are generally associated with the gypsums. There are also beds of this mineral in the Laurentian, etc. of Cape Breton, and in the Cambrian and Silurian measures, but they do not usually form deposits of economic value. The carboniferous limestones are strongly developed in Cumberland, Colchester, Hants, Kings, Pictou and Antigonish Counties, and at muny points in Cape Breton. They occur in beds varying in thickneiss from a few inches to 50 feet, and in some localities their aggregate dimensions will exceed 400 feet. Their quality varies from calcareous sandstones and clays to the almost crystalline pure mineral. At Windsor, Brookfield, and many other localities beds are found composed entirely of fossils, characterising the Marine Limestone forma- tion, and gave the following component parts on analysis by Dr. How : Carbonate of Lime , 97*64 " Magnesia 1 '10 Oxide of Iron 07 Phosphoric Acid trace Insoluble residue "68 A limestone similar to the above is extensively quarried at Brook- field as a flux for the Londonderry iron ores, the quantity forwarded for this purpose in 1878 and 1879 being about 16,000 tons. The limestones of Pictou County are also well adapted for fluxes,, and will be found useful whenever smelting operations are commenced on the East River. The following analyses of a limestone from lame Brook, Spring ville, were made for the Halifax Co. at the Durham. College of Physical Science : 108 NOVA SCOTIA MINES I. 11.

The position of the East River limestones, forms an important item in their adaptability for fluxing purposes; they occur as a band everywhere between the coal and iron, so that their transport becomes a matter of comparatively low cost, and large quantities are available by simple quarry work. Some limestones at Horton, Onslow, the Joggins, Pugwash and other places are bituminous, and contain notable quantities of phosphoric acid. As already mentioned, some of the East River limestones contain important per-centages of carbonate of iron, and may, at some localities, afford an ore of this metal, in addition to the Spathic ores referred to before. In Cape Breton, several places are known which afford marbles, be- lieved to be well adapted for building and decorative purposes. The finest deposit of workable limestone yet discovered, is on West Bay, Bras d'Or Lake. In variety of color and tint, this rock resembles the limestones of the George River series, of which it fonns a part, but it contains little or no admixture of foreign materials, and is uniform in texture and in unequalled abundance. The following varieties have been recognised : 1. Fine white statuary marble. 2. Fine white building " 3. Coarse white building " 4. Blue and white clouded " 5. Brocatello marble mixed with .six varieties of colored marbles. 6. Fine flesh colored marbles, often striped and variegated. The locality offers every facility for quarrying and shipping, and on the completion of the St. Peters Canal, blocks of any required dimen- AND MINERAL LANDS. 109 tions can be cheaply shipped to the United States, equal in quality to those already admired as samples. At St, Anne's Mountain, Cape Dauphin, Salmon Creek, Whyhogo- mah. River Dennis, George River, French Valley and Escasonie, marbles are also found ; at the latter place they are usually too much broken and mixed with other rock to be available for artistic purposes. At Five Islands, Colchester County, promising marble deposits are known. The carboniferous and other limestones are quarried at all points for lime for building and agricultural purposes. That from East Bay has been extensively burned for lime, as has also that from the George's River beds, which '' rnished in 1876 about 6,000 barrels, invoiced at 80 cts. a barrel. Tl ova Scotia lime is frequently brown, arising prob- ably from carelessness in selecting and burning ; its price per barrel may be averaged at 95 cents. At numerous points in the Province, the lime- stones contain foreign ingredients, indicating the presence of a certain amount of hydraulicity, such as Alumina, Carbonate of iron. Magnesia, Silica, etc. The well-known Portland Cement was invented in accordance with the desire for a material which would set rapidly, and remain indurated in water. Lime, itself, is useless for this purpose, unless mixed with the proper proportions of an argillaceous compound. Many good natural cements, such as the Roman Cement, have been used at various times, but the want of uniformity in the composition of the calcareo argillaceous rocks they were made from, soon rendered their action even dangerous. There are several nattiral cements still made, resembling the Port- land compound in composition and qualities, such as the Boulogne and English Lias, as shown by the following analyses : Lime. Silica. Alumina. Iron Oxide. Hagneaia. Portland Cement.. 62-0 23-0 8-00 4-0 Boulogne " .. 65-15 20-42 13-87 ... -58 One important difference between the natural and artificial cements, is the shrinkage in setting of the former. This, and the difficul*^^}; ^ preserving uniformity of composition, have gradually led to the abi* exclusive use of the artificial cement. The general character of the materials used in the manufacture of Portland Cement may be gathered from the following analyses :* Chalk — Lime, 56-5 Carbonic Acid, 43*00 Water, -5 Clay — Silica, 6845 Alumina, 11-64 Lime, "76 Iron Oxide, 14-80 Soda, 4-00 ^*R«id— Treatise on Concyett. 110 NOVA SCOTIA MINES The proportions used are from 65 to 75 per cent, of chalk ; and from 25 to 35 per cent, of clay — any kind of chalk being suitable ; but the clay should not contain above 14 per cent, of iron oxides. The process of manufacture, which is too long for proper description here, requires intelligent supervision, to produce an article of uniform quality. In Germany, limestones are used instead of chalk ; but the cement very closely resembles that made in England. In this Province, although many limestones possess hydraulic qualities, their uniformity cannot be relied on. Hence, our cements, which are natural ones, have never proved permanently satisfactory. The limestones and clays of the Province will answer for the manufacture of cement ; but the absence of chalk, requires more care in the manipulation of the limestone, and a consequently increased cost.. The present selling price of Portland Cement, in Halifax, is $4.25 per barrel. The amoiKit imported in 1877-8, was 76,847 barrels, valued at $106,018.00 J and the importation of last year was valued at $66,832.00. The expense of manufacturing this article in the Province would be considerably under that of the imported cement;, and a lessened price would extend its use in all building operations, as it is, when properly applied, better suited for this climate than the ordinary mortar. At present I am not aware of any Nova Bcotia cements in the market j the Portlant Cement being generally called for in contracts and specifications. Among Nova Scotia limestones possessing hydraulicity may be mentioned those from Horton, Windsor, St. Peter's, Chester, Onslow, Shubenacadie, Spring Hill, Whyhogomah, etc. In the lockwork of St. Peter's Canal, Portland Cement alone was used. The quantity burnt for agricultural purposes must be very consider- able ; but no returns are made of Ifte amount ihus used, and in very many parts of the Province, nature has supplied this fertiliser in abund- ance. The Mines Department gives the amount of limestones and ankerite quarried during the years 1874-9, at 39,327" tons, but this refers only to that used for smelting purposes, and dees not include the amount extracted by individuals throughout the Province. y AND MINERAL LANDS. Ill CHAPTER VIII. REFRACTORY MATERIALS. — PLUMBAGO. — FIRE CLAY. — SOAPSTONE. TERY CLAY. — KAOLIN. POT- Plumhago. — This mineral is not uncommon in the Province, although as yet no deposits have been worked. Among the localities affording it may 430 mentioned — Parrsborough, Salmon River, Musquodoboit, Ham- monds Plains, Fifteen-Mile Stream, Boularderie Island, Gregwa Brook, and Gillis Brook, Cape Breton. These deposits are, in many cases, really highly plumbaginous shaleS ; but were attention directed to the subject, some might be found of economic value. In Ontario and Quebec valuable deposits of this mineral occur in the Laurentian lime- stones, and much interesting information on their extent and nature is to be found in the Survey Reports. The Report for 1876-7 contains a valuable paper by Mr. Ho£fman, on Canadian graphites, compared with those of Ceylon. From the returns of 1878 this mineral does not seem to be mined at present in England. Formerly only the pure granular varieties were in demand, but a much more impure ore can now be utilised ; and the ex- ports of Plumbago from Canada for the year 1878-9 were 1,029 tons, valued at $3,627. Its applications are so well known that they need not be enumerated here. Fvre Clays. — Clays are essentially hydrated silicates of alumina, also holding moisture. Their plasticity, when mixed with water, depends on the presence of the water of composition, and when heated to redness, it is driven oflF, and they lose this property. When these clays stand a high temperature without melting or softening, they are termed refrac- tory or fire clays. They occur in various geological formations, those of the best quality being generally obtained from the coal measures, where they usually form the beds underlying the coal seams. 112 NOVA SCOTIA MINES The mechanical mixtures accompanying clays are silica, carbonates of lime and magnesia, pyrites, etc. They affect the heated clay in various ways, by causing unequal expansion and cracking, and by forming fusible slags. These effects depend not only on the amounts of the impurities, bukalso on their relative proportions, as in the case of furnace slags. Among the purer clays are those holding large pro- portions of pure silicious sand, as the celebrated Dinas brick clay. Fire brick are required to stand, in some cases, high and prolonged heat, alternations of temperature, not to soften when heated, or run when in the presence of heated metallic oxides. Any one clay will seldom meet all the above requiiements, and various materials are added to counteract the failing, such as sand, powdered millstone grit, clay previously burned and ground, etc. The method of making fire brick resembles that followed in the manufacture of common brick. The clay, after weathering, is carefully ground, etc., and burned for five or six days in kilns of 15 or 20 thousand. The following analyses will show the character of typical English fire clays : Stourbridge. Newcadtle-on-^yne. Dowlaii.

Numerous attempts have been made in this Province to find clays suitable for the manufacture of fire brick, as the value of the article imported in the raw and manufactured state during the years 1877-78, amounted to $52,233 and $35,749, and the demand is likely to increase. The following analyses will show the composition of several Nova Scotian fire clays : ,.t AND MINERAL LANDS. 119 Lingran.' D««p 8e«m. Spring Hill.- Stewiacke.t CozhMth, C. B.

The fire clay from Coxheath Hills, Cape Breton, is an altered felsite, compact, lustre pearly to dull, color pearl grey, greasy to the touch. The analyst, Mr. Hofiman, G. S. R., 1875-6, gives the results of numer- ous experiments, from which ii appeared that the rock alone would not make a brick, as after burning the mass remained friable. When from half to one per cent, of lime was added an excellent refractory brick was produced. Large quantities of this rock, which is well worth a practi- cal test, are reported by Mr. Fletcher to be exposed at Watson's Brook, and several localities in the Coxheath and East Bay Hills, -as Big Pond, Gillis and Forks Lake brooks. During 1879, a few tons of fire clay were burnt into good brick by Mr. Cameron, of Stellarton, and are being used in the construction of Coke ovens, by the Halifax Company. The clay is from a bed overlying the McGregor seam, and is four feet thick where opened on the land of the Halifax Company. I understand the manager of the Londonderry Iron Works considers it well adapted for metallurgical purposes. Messrs. Mackintosh and Dewar, are now building at New Glasgow, a plant for the manufacture of fire brick from this clay. The quality of the clay is said to have proved, under severe tests made in England, to be of the very best. It is to be hoped that this enterprise willi^rove successful, as the demand for this article is increasing every year. Doubtless as the search is extended, other clays will be found suitable for refractory bricks, linings, etc., and in this connection the large deposits of infusorial or silicious earth found in many of our lakes, etc., may prove of value. E^fractory Stones. — There has been so little demand for such materials that scarcely any information can be given. Some of the metamorphosed * Analyst unknown. tE. Gilpin. 114 KOTA SCOTIA MINES Upper Silurian clay slates of Piotou County afford stones which have been successfully used for lining cupolas, boiler furnaces, etc. I have tested the fire resisting qualities of several sandstones from the ,Pictou coal field, but did not find them valuable. The upper coal measures may yield sandstones adapted for furnace hearths, etc. Soapstone has been found, I am informed, in Oape Breton, near Louisburg, and at other points ; but I am in possession of no details as to its quality, etc. At the Exhibition of 1879, very handsome samples of pottery, vases, jars, ornaments, besides tiles, drain pipes, dishes, etc., were shown by Smith & Kaye, Homsby & Flavin, Messrs. Harrison, and others. From these the adaptability of the various white anil red clays to the potter's art, was satisfactorily shown. Some years ago, pottery was made near New Glasgow, from a coal measure clay, but work has been discontinued. ** Kaolin has been found in small beds, at several places on the Atlantic coast, resulting probably from the decomposition of feldspar. As yet, however, it has not received any attention. In Oomwall, a large busi ness is carried on in this material, some of which is worked into porcelain, etc., on the spot, and the rest taken to the midland counties. The returns for 1878 give, under the Metalliferous Mines Act, 60,261 tons of potters' and other clays. , AND MINERAL LANDS. 110 CHAPTER IX, MATERIALS FOR GRINDING AND POLISHING. — INFUSORIAL EARTH. — GRIND- STONES. — MILLSTONES. — WHETSTONES. • Inftiaorial Earths. — The deposits of this material at present known are found chiefly in the lakes of the Atlantic coast, and in some bogs and swamps, which have resulted apparently from the filling up or drainage of similar waters. Wentworth, Country Harbor, St. Anns, Glrand Lake, Lochaber, French River, Earltown and Oomwallis may be mentioned as localities yielding it. Beds of it are found 8 feet thick in the lakes supplying Halifax with water.* It is employed for polishing, etc., and the silicious varieties may be found useful in the manufacture of fire and bath brickSt Grindstones. — At several points in the Province stones are found admirably adapted for the above purpose. Among the best known localities may be mentioned the Joggins, Pugwash, Glenville and Pudsely's Point, where the stones are taken from a reef, uncovered at low water, having a thickness of 20 to 30 feet. At Port Philip, both red and gray grindstones are made of all sizes, up to seven feet in diameter. Several cargoes have been shipped from Merigomish, and stones are cut for local use at several points in Cape Breton. Granite is the material generally used here for the manufacture of millstone^, a/itl for convenience they are cut usually from the boulders found everywhere in the Province. In Ontario the stone used for this purpose is a brown cellular chert, having irregular cells, varying in diameter from a sixteenth to three-quarters of an inch. The deposit occurs filling vein-like fissured in Laurentian Syenite, and is supposed to have been deposited by water. Whetstones are made from sandstoneti having an argillaceous cement, frequently micaceous, at numerous points * Prof. lAWtCD, N. S. Inttitute Nstural Science, Januitry, 1880. I-: 116 NOVA SCOTIA MIKES n the Province, as the Joggins, Parrsboro, Colchester County, MerigomUh, etc. The cennusof 1871 returned 2 grindstone factories in Nova Scotia, giving employment to 118 persons, with an annual product valued at $37,442. V Our chief exports of grindstones and scythe-stones are from the Joggins. Small quantities are also sent from Parrsboro, Merigomish, etc. The returns of the Mines Department give the exports of grind- stones for the years 1875-76-77 and 79— (returns for 1879 not mad« up) — at $99,660, and of scythestones for the same years at $8,894. i JkJtX> MIVBKAL LANDI. 117 CHAPTER X. PRBCI0U8 STONES. — TRAP MINERALS. Precious Stoiies.-Our list of precious stones for the purpose of ornament, etc., is a very limited one. A specimen of Topaz was shown at the Lon- don Exhibition of 1872, said to have come from Cape Breton. This may have been a yellow corrundum. Garnets are very common in the more highly metamorphosed slates of the gold districts. They vary in size from a pin's head to crystals one half an inch in diameter, but, I believe, are generally found to be too brittle for the purpose of the jeweller. Crystals of quartz, commonly known as rock crystals, are very common 1 a the older rocks, and are met in great beauty in some of the gold leads. The mineral, however, is so abundant that they would be valuable only if there were a home demand to admit of their being worked here. Amethyst, purple quartz, is a very common mineral in the trap dis- tnots, where it occurs as crystals and incrustations often of considerable size. Its value depends entirely on its depth and uniformity of color. Specimens from Nova Scotia have been much admired in England and on the continent. The early French settlers sent considerable quantities home, and one very handsome specimen was divided in two, and placed in the crown of one of the French Kings. Among localities yielding it, may be mentioned Farrsboro, Digby Keck, Cape Sharp, Blomedon, Comwallis, Sandy Cove, etc. Smoky quartz, cairn gorm stone, is very abundant at Paradise, Annapolis County, and many of our auriferous veins present varieties of it. Heliotrope, Jasper, Chalcedony, Agate and Common Opal, are also frequently met in the trap districts. The Helio- trope, or blood-stone, finds a ready sale when in good specimens. The trap of the Bay of Fundy has acquired an almost world wide reputation for the variety and beauty of its minerals, which have been formed by the dissolving and concentrating agency of water acting flirough long ages. H^HV 118 NOVA SCOTIA MINES Dr. Gesner, the late Dr. How, and others, devoted much time to the determination and collection of these minerals, and very beautiful cabinets have been exhibited at various times. It would be foreign to the aims of this report to describe, even in the briefest terms, the various minerals and their localities, as they possess scarcely any econo- mic value at present. The following list embraces those best known : — Albin, Analcime, Anatase, Apatite, Apophyllite, Calcspar, Centrai- lasite", Cerinite, Ohabazite, Chlorophoeite, Chlorite, Oyanolite, Faroelite, Green Earth, Green Calcspar, Gyrolite, Heulandite, Laumonite, Leder- ite, Mosolite, Mordenite, Moss Agate, Natrolite, Obsidian, Phrenite, Poonah Earth, Scholesite, Sinter, Stilbite, Tremolite, Thomsonite and Wichtesite. Those who desire further information on the subject of these trap minerals, the identification, physical characteristics, etc., of their varieties, will find Dana's Mineralogy the best text book. AND MINIHAL LANDS. 119 / CHAPTER XL MINERALS OF THE LAURBNTIAN STRATA. — TENURE OF MINERAL LANDS. — UNITED STATES MINERAL TARIFF. I venture to draw your attention to a series of measures which may be found to hold valuable minerals in Nova Scotia. Under the term Laurentian, or, according to the new nomenclature of the Survey, Huronian, are included a great mass of rocks, comprising reddish orthoclase gneiss, quartzite, crystalline limestones, dolomites, etc. These measures stretch from the Labrador far into Canada, and also occur in Cape Breton and Nova Scotia. With these rocks are associated in Quebec and Ontario five important minerals — Hematite, Magnetite, Apatite (phosphate of lime), Mica and Graphite. The more important deposits of Canadian iron ores are found in these measures, as beds and lenticular interstratified masses often of large size. Many of the ores are of great purity, and hold very small per-centages of sulphur and phosphorus. At various times large quantities of these ores have been exported to the United States. Of late years the export has greatly decreased, but is reviving again. The amount exported during 1878-79 was 3,562 !ons, valued at |7,530. • Apatite. — This mineral, which forms the basis of the soluble super- phosphates, used extensively for manure in England, promises to form a valuable adjunct to the mining and manufacturing resources of Canada. It occurs in veins in the limestones and associated strata, frequently crystalised, also compact and granular. Its color varies from green to yellow, with blue and reddish hues, with resinous to oily lustre. Its hard- ness is 5, or readily scratched by quartz, and it is brittle. This apatite contains usually a high per-centage of phosphate of lime, and is, with proper treatment, well adapted for making concentrated superphosphate. The Canadian mineral contains 4^ to 7 per cent, of fluoride of calcium, whioh, during the usual treatment, yields hydrofluoric acid, which msm ^ r.^l3ES!M0BBBSS_JH 120 KOVA SCOTIA IIIHBI injareg the health of the workmen employed. This objection, however, has been obviated by new processes, and Canadian, Norwegian, Spanish and Nassau phosphates can now be treated without inconvenience. Tho mineral has been generally shipped in lumps, but should be ground and barrelled, which facilitates handling and sampling. The amount ex- ported during the year 1878-9 was 11,927 tons, valued at $216,295. The appearances and uses A mica and graphite are so well known that I need not take up your time by a description of their physical properties. The G. S. Report 1876-7 contains a valuable paper by Mr. Hpfiman, comparing the Canadian graphite with that exported from Ceylon. His experiments show that the Canadian graphite is as pure as that from Ceylon, and equally adapted for crucibles, etc. The graphite occurs in the form of scales, disseminated in limestones and gneisses, or in veins cutting these rocks. Rocks containing as low as 2-4 per-centage of graphite can be treated by stamping, buddies, etc., to yield a marketable product. The folliated variety, however, is found to be purest. Considerable quantities have been mined ^nd manufac- tured in Ontario. The mica occurs frequently as crystal* in the lime- stones, usually near int«rstratified maases of pyroxenic gneiss, etc., and plates have been cut 20 by 30 inches. The labors of the Geological Survey have already shown the pre- sence in this Province of considerable areas of this series of rocks, and it appears probable that their extent will be found larger than at pre- sent is currently believed to be the case. The similarity of the strata over so wide an area, as dwelt upon in these reports, leads to the hope that they may here be also characterised by the valuable minerals re- ferred to above. This view^is supported by the discoveries of valuable ores of hematite, already alluded to. ^ TENURE OF MINERAL LANDS. The grants of land to the early settlers in this Province, contained no regular reservation of minerals ; in some instances, gold, silver and precious stones alone were reserved, in other cases the gold, silver coal, iron, copper, lead, etc., were retained for a source of revenue to the Crown. After the agreement, with the General Mining Association, the Government peussed an act, by which they retained in previous grants, the gold, silver, copper, iron, lead, tin, coal and precious stones whenever mentioned, and made the above reservations in all future grants for the purpose of revenue. This act releases to the owner of the land, all minerals not mentioned above, such as limestones, gypsum, fire clay, IV\ AND MINSRAL LANDS. 121 bai'y+^s, manganese, etc., and any of the above reservations whenever they are not specified in the grant. There is no complete list published of the various grants, but full information as to the position, date and reservation of every grant, can be obtained from the Crown Land Office. The Department of Public Works and Mines }s entrusted with the col- lection of the revenue from the Mines ; and all leases are issued by it, etc. Gold areas are obtainable for three months as prospecting licenses, and as leases for twenty-one years, with the right of renewal. The cost of the license, which must not exceed one hundred acres in ex- tent, is at the rate of 50 cents per acre, up to ten acres, and 25 cents for each additional acre. The lease will cost two dollars for each lot measuring 250 by 150 feet. Mill licenses are issued, and the regula- tions are all framed with a view of facilitating the operations of* the miner. Licenses to search, covering 5 square miles of ground, and lasting one year, are issued for other minerals, at a cost of $20 ; and leases can be procured for a term of twenty years, renewable on com- plying with the requirements of the law of Mines and Minerals. The following are the royalties paid by these holding property under lease from the Government. Nine cents and seven tenths of a cent on every ton (2,240 Rs) of coal coarse enough not to pass the interstices of a screen having its bars f of an inch apart, the fine coal and that «sed for colliery workmen and engines being free ; three cents on every ton (2,000 S&s.) of iron ore ; ten cents on every ton (2,000 lbs.) of copper ore, and five per cent, on the value of all other ores and minerals, except gold, which pays a royalty of two per cent., at the rate of $19 an ounce, Troy, for smelted gold, and $18.50 an ounce, Troy, for unsmelted gold. Full information on all points connected with this subject, will be found iii the law of Mines and Minerals. All the regulations connected with the leasing and working of the Provincial Mines are framed with the view of affording all proper and Mecessary facilities to those desirous of entering into mining operations, and among not the least of these advantages may be mentioned the absolute security of the titles, granted and registered by the Govern- ment.
