PROSPECTUS. 
 
 The New Hampshire Silver-Lead Company is organized un- 
 der the laws of the State of New York for Mining and Manufac- 
 turing purposes. The Capital Stock of this Company consists of 
 100,000 Shares of nominal par value of $5 each, 80,000 Shares of 
 which were paid for the mines in fee, situate in the township of 
 Lyman, Grafton County, New llamphire, said stock not assessable; 
 the remaining 20,000 Shares being reserved for working capital, to 
 be disposed of by order of the Board of Trustees, 5,000 Shares of 
 which are now being sold at $2.50 per share, and issued as full paid 
 stock not liable to assessment. This Company has been organized 
 under the most favorable auspices, the mines having already been 
 sufficiently developed to produce some of the finest and richest 
 Silver-Lead Ore ever found in this country, yielding, according to 
 several assays, about 80 per cent, of Lead v.Ad from 35 to 57 oz. of 
 Silver to the ton of galena, the present value of which ore is about 
 $500 per ton. It will readily be seen from the statement of Prof. 
 Wurtz, hereto annexed, showing the relative value of each of the 
 metals contained, that either the Lead or the Silver alone, would 
 produce a large revenue, and that the two combined cannot fail to 
 become very remunerative, inasmuch as ample provision has been 
 made for a large working capital, in order that the proceeds of the 
 mines may be divided amongst the Stockholders. The mines of 
 this Company consist of five valuable veins already explored, and 
 
several unexplored veins, luniiing nearly the entire length of the 
 property, (1(10 acres,) and located on the eastern f^lopo of Gard- 
 ner's Mountain, very advantageous for mining expeditiously and 
 economically, having natural drainage to some of the veins through 
 adits to the depth of from 75 to 200 feet. 
 
 The Company have already located several shafts and adits, and 
 are now sinking a shaft on one of the largest veins, by contract, 
 twelve feet by six feet, sixty feet deep. The locating of these 
 shafts and adits has been done by the best professional geological 
 skill, together with tlie experience of the best practical mining 
 engineers in the country. From explorations already made and 
 ore obtained, it is believed there is also a very valuable Copper 
 Vein upon this property, and as soon as practicable the Company 
 intend to further develop it, confident of a very large yield of that 
 ore. A very great advantage which the locality of these mines 
 presents, is, that it is within six miles of railroad communication, 
 making the expense of transportation to market very light, and 
 accessable at all seasons of the year. It is the intention of this 
 Company, with the excellent facilities which it has, by proper and 
 careful management of its operations, to make it a permanent and 
 profitable investment for the Stockholders. Specimens of the ores 
 from these mines may be seen, and copies of this prospectus ob- 
 tained, at the oflSce of the Company, 
 
 71 Broadway, 
 
 New Yorli, 
 
 Annexed wi'l be found reports from Professor Henry Wurtz, 
 upon the property of the Company, together with reports of Dr. 
 John Torrey, U. S. Assay OflBce, upon the assay of the ores; also 
 report of Samuel Truscott, practical mining engineer, all of which 
 are respectfully submitted.

 ON THE PItOPEBTT OF THE

 IK THE TOWHSHIP OF LTHA5, OBAITON OO0IITT, 
 
 Ne^v Hampshire* 
 
 Gentlemen — The preliminary examination, which I have made 
 of your property at this place during the past week, enables me to 
 report as follows: 
 
 This property is located upon an exceedingly well-marked belt of 
 metalliferous rocks, composed chiefly of talcose and quartzose 
 schists, which crosses a small portion of the State of New Hamp- 
 shire, in a direction from N. E. to S. "W. 
 
 Owing to a large, nearly semi-circular, bend in the Connecticut 
 River, forming the State Line, in the concavity of which bend this 
 locality lies, the portion of the outcrop of this metalliferous belt 
 lying within the State of New Hampshire is quite limited; and this 
 is probably the reason why Dr. Charles T. Jackson, in his excellent 
 geological survey of this State, appears to have given this district 
 but a very cursory examination. 
 
 He has marked down upon his geological map, however, one 
 locality of copper ore, another of lead ore, and another of iron ore, 
 situated upon this belt, within the limits of Lyman township; and it 
 would appear, judging from the direction indicated by residents of 
 
 ^ I 
 
the neigliborliood, for a loralily spoken of by Dr. Juckson, in Bntli 
 township, on tlio proporty of Mr. If. Lanuf, that thi-t locality also 
 Hhould lio upon tho same bolt, or range, thougii not marked thus on 
 Dr. Juckson's map. 
 
 Dr. J. j^ivorf tho followiii;? des( rii)lion of fijinji's locality: 
 
 •* Two veins occur near tlio lesidence of Mr. Lang's tenant, Mr. 
 Hunt, on tho margin of n small brook, in a ravine over tho hill; 
 and a large detached block of very pure ore, 2J loot in diameter, 
 was found in tho meadow below tho ravine, and must have boon 
 derived from some vein in the vicinity. The vein on this hill runs 
 N. 50 deg. W. (N. 50 dog. E. ?) nearly in the same dirccticm with 
 the slate strata. 
 
 " A cross vein, having a course N. 45 deg. W., is from one foot 
 
 to eighteen inches wide, and is mixed with fragmen(s of slate, 
 
 forming with it a breccia. Over tho hill, in the ravine, tho vein 
 
 . is from four to eight inches wide, and a cross vein is two inches 
 
 wide. 
 
 " Tho copper ore on this estate apjioars worthy of lieing wrought, 
 and by mining operations it can be ascertained whether tho veins 
 continue to be rich as they descend. By a single blast we raised 
 nearly 100 lbs. of good copper, whicli would yield about 20 per 
 cent, of pure metal." 
 
 In another place Dr. J. gives the results of two analyses of the 
 . copper pyrites of this locality, which indicated respectively ^2.5 
 and 31.92 per cent, of metallic copper. 
 
 It is also interesting to remark, that one of the few localities in 
 . Vermont mentioned by the State Geologist of that State, Prof. 
 . Adams, where copper pyrites had been found in any quant ity. prob- 
 ably lies on the southwesterly prolongation of tho same range. 
 This is at Corinth, Orange Co., Vt. 
 
 Prof. A. states that at that time copper had been found along a 
 line bearing N. 10 deg. W. for 200 rods. At one place tho vein 
 was more than a foot wide. I understand that some mining has 
 
• 
 
 
 Hinco bcon done at thin place, but liavo no furthor Information on 
 the «ul»j«'ct. 
 
 TIio portion of thin raetallilcrous bolt crossing your property in 
 Lyman 1ms a course somowliut leas westerly than that attributed 
 by Dr. Jackson, (us inferred I'rom <ii<' above, N. TjO (leg. W., being, 
 no doubt, a misprint for N. HO deg. E.,) to the schists on Lang'a 
 prop(M'ty, l)eing about duo N. E. and S. W., the dip being south- 
 easterly, and at Ickn! 45 deg. from tho horizontal. 
 
 These schists have, in most places, more or Ics-a of a talcoso 
 character, though in some places passing into a quartzose schist. 
 
 The country is overywliero hii^hly metalliferous, the indications 
 of this being obvious to an experienced eye almost at first glance, 
 in the very frequent occurrence of masses of honey-combed quartz, 
 usually containing more or loss liinonito gozzan, indicating tho 
 past existence of metallic sulphurefs. In some places a large per- 
 centage of the stones of which the fences are built are of this 
 chara(;ter. 
 
 I, myself, picked out of a stone fence such a mass of quartz, still 
 containing bnnehes of galena and blende. 
 
 The schists themselves, in most places where exposed, are loaded 
 with small partic es of limonite, derived, as was seen in places 
 where avc blasted into it, from more or less thickly interspersed 
 crystals of pyrites. 
 
 In niany places the ledges of schist were st;iincd and encrusted 
 with Jimomtv. 
 
 Everywhere throughout these schists wore found seams and 
 bunches of quartz, sometimes assuming the form of thick beds, con- 
 formable with tho stratification, sometimes even that of fissure 
 veins crossing the stratification at an angle. 
 
 Such quartz was almost invariably accompanied by the well- 
 known indication?, of carrying, in depth, more or loss of tho metal- 
 lic sulphurets, or ores; the particular ores observed, so far as 
 opened, being common iron pyrites, copper pyrites, galena and 
 
 ;

 blende. The proportion of silver in the galena will bo determined 
 by the assays, now in progress by Dr. Torrey, at the United States 
 Assay Office. 
 
 The most important of tlicse quartz formations found upon the 
 property, were three thick beds, cropping out and forming three 
 heavy parallel ledges at diflfcrcnt heights along a very steep hill- 
 side, on the western side of tlie tract, known as " Gardner's Moun- 
 tain." There was only time to give special examination to the 
 lower or most easterly of tliese three heavy quartz outcrops, though 
 it is to bo presumed that thoy will all three be found similar in 
 character. 
 
 This outcrop, whicli we have called JFeat Lode, No. 1, is com- 
 posed of highly metalliferous quartz, intercalated between the beds 
 of the schists, and having the same strike and dip as the latter. 
 
 No place was found where the walls were distinctly visible, and, 
 therefore, no measurement of its thickness could be made. I am 
 inclined to estimate its average thickness, however, as at least ten 
 feet, and it may be more. 
 
 The blastings which I directed to be made will shortly determine 
 this point. 
 
 This lode of quartz cannot be regarded as presenting all the 
 characteristics of a tmejissiire vein, but this is of little practical 
 -mportance, the outcrop being distinctly visible, and of great thick- 
 ness for a distance of at least four or five hundred yards, and no 
 doubt extends much further still where it is not visible; so that no 
 reasonable fear can be entertained with regard to the supply of ore 
 bearing material. As regards the character of this material, the 
 surface indications are also very encouraging, the quartz, at one 
 point where we have made two small excavations, marked A and B 
 on the map, one near the foot wall side, and the other near the 
 hanging wall side of the lode, showing numerous strings and bunches 
 of galena, with some copper pyrites, together with gozzans and 
 honey-combed cavities, indicating an increase in the proportion of 
 metals in depth. 
 
11 
 
 A very encouraging feature was the finding of many cavities 
 or " vugs," lined with beautiful crystals of quartz, in some of which 
 there was much gozzan, intermixed with decomposing crystals 
 of galena and yellow copper. A feature of the greatest importance, 
 and encouraging the expectation of an increase of copper in depth, was 
 the generally clear and untarnished appearance of the few crystals 
 of iron pyrites found, which shows the gozzans to have been chiefly, 
 if not wholly, derived from copper pyrites. 
 
 In fact, in some places gozzan was found distinctly passing into 
 yellow copper, some specimens of which were brought back, so that 
 the indications are quite strong tliat, in addition to the silver lead, 
 an important quantity of copper will be found in depth on this 
 lode. 
 
 In one vug was found a quantity of a rich blue powder, which may 
 have been indigo copper. 
 
 Until further excavation has been made in this large quartz lode, 
 no certain opinion can be formed as regards the certainty of finding 
 here the regular structural features of a fissure vein; but still 
 it may with some confidence be calculated that, even should it be 
 merely a large " segregated " bed of quartz, certain structural lines 
 will exist, along which the metallic minerals will be found more or 
 less concentrated, and the tvidth of such a lode will enable such 
 richer portions to be followed up and taken down, without much 
 waste of labor on the less productive tracts of the veinstone. With 
 regard to the further exploration of this lode, the proper course 
 seems to be to carry such explorations from the point now being 
 opened toward the S. W., in which direction the ground at the foot 
 of the mountain falls off rapidly; and if the surface indications con- 
 tinue to promise as well in that diiection, a short adit would 
 in many cases cut the lode, and the subsequent operations could be 
 guided by the developments made. Should surface blasting show 
 that the west lodes No. 2 and No. 3 possess the same metalliferous 
 character as No. 1, cross cuts may be driven to them from any 
 
12 
 
 suitable point in the workings on No. 1. and a great depth of drain- 
 age obtained upon them. 
 
 Proceeding from the foot of Gardner's Mountain southeasterly, 
 wo find, iirst, two wide outcrops of nchist, the outcropping edges of 
 which are greatly st/-ainod and encrusted with limonite, indicating 
 for the country here a highly metalliferous condition — this country, 
 as will be observed, being adjacent to the hanging wall of the west 
 lode, No. 1 — a circumstance which must certainly be regarded as 
 highly encouraging to the expectation of finding tliat portion of 
 this lode which dips beneath this rich country proportionately rich 
 in metals. 
 
 Proceeding further, in a southeast direction, to a distance alto- 
 gether about 220 yards from the opening in west lode No. 1, we 
 encounter a group of outcrojis of quartz of a character difl'ering con- 
 siderably from those described above. 
 
 Hero are two well-marked fissure veins, somewhat iri'egular in 
 thickness and in dip, but having a course about N. 50 deg. E.; the 
 same, therefore, as given by Dr. Jackson for the copper vein on 
 Lang's property. 
 
 These veins each appear to bo, on an average, about two feet in 
 width; are known as Orchard Veins Nos. 1 and 2. Orchard Vein 
 No. 2 being a new discovery by your mining captain, Mr. Truscott, 
 and not yet explored to any extent, nothing can be said about 
 it, except that gozzans and honey-combed quartz appear in it, and 
 that no doubt can be entertained of its proving altogether similar 
 in character to its companion, Orchard Vein No. 1, and that both 
 these appear to belong to a system of small fissure veins traversing 
 the country, more of which will, in all probability, be discovered. 
 
 A strong quartz outcrop, discovered by Mr. Osborn and myself, 
 in the barnyard of Mr. Bailey, seems to lie near the course of 
 Orchard Vein No. 2, and has been marked provisionally on the 
 map as belonging to that vein, though it may turn out to belong to 
 another parallel vein. 
 
13 
 
 Orchard Vein No. 1 is of much more immediate interest. It was 
 discovered twenty years since, in sinking a well for the farm-house, 
 at the poi t; E, and was traced Fonie few yards northeasterly to P 
 and G, \: ..re several blasts have been made into it. The well is 
 about 18 feet deep, and this vein is sufficiently developed to enable 
 some idea of its nature to be arrived at. 
 
 There can be no doubt of this being a true fissure vein, somewhat 
 irregular at the surface in its thickness and dip, but regular, so far 
 as is known, in its course. From F to G were taken out, besides 
 largo quantities of gozzan, many specimens of galena and blende, 
 still undccomposed. 'i he excavations made here, however, have 
 been but three or four feet deep. Parts of the quartz showed 
 a strongly-marked, comhy structure, so characteristic of true fissure 
 veins. Much more was made out by descending into the well at E. 
 Until within a few feet of the bottom, the quartz vein at that point 
 was quite irregular, much branched, and divided by a large horse, 
 the vein itself being mostly barren, though its walls were filled 
 with large masses of rich-looking gozzan. Towards the bottom of 
 the well, however, a change appeared, the vein becoming more 
 regular, about two feet thick, with a steep dip to the southeast, 
 carrying is (/"large quantities of gozzan, and its wall , which con- 
 sisted above of a rotten, highly talcose schist, assuming here the 
 character of capels, or becoming very compact, hard and quartzose, 
 and becoming loaded with brilliant crystals of pyrites. 
 
 This system of small fissure veins is well worthy of further 
 exploration, although, as before stated, no hesitation can exist in 
 pronouncing the west lode No. 1 to be the portion of your property 
 possessing the most immediate importance, and calling for earliest 
 thorough investigation. Their course, so far as they have been 
 observed, being so nearly parallel to that of the west lodes, it 
 is concluded, from general analogy with other known districts, that 
 their metallic contents will be similar, and both the galena and 
 blende of these fissure veins will probably be found to contain, in 
 
IftfeT^V 
 
 u 
 
 any case, much silver. To determine this important point, much 
 labor was expended in picking out from the decomposed gozzans 
 and quartz, at the openings F G, a sufficient quantity of the small 
 particles of the galena for an assay, for both silver and gold, the 
 results of which will be given in the report of Dr. Torrey, to be 
 appended to this. 
 
 In proving this system of veins, below water level, it will be 
 advisable to mark out the course of one of them, where it should 
 cross the low, swampy ground lying southwesterly from the points 
 D and E, and to sink a shaft here at some point a short distance to 
 eastward of this course, the dip of these veins, as above stated, 
 being apparently southeasterly. From the bottom of this shaft, a 
 cross cut made in a direction from N. E. to S. W. will, of course, 
 intersect all these veins about at right angles. 
 
 To sum up my chief reasons for believing that this will prove to 
 be a highly valuable mining property: 
 
 1. The highly metalliferous character of the range, which is par- 
 ticularly apparent in the country which overhangs the dip of the 
 three great west lodes, and appears also in the existence of the 
 other known localities of metallic minerals in the range. 
 
 2. The great magnitude and extent of the west lodes, which 
 throws out of estimation any near possibility of exhaustion of the 
 mining ground, and at the same time enables judicious selection 
 and discrimination to be made in following up the most promising 
 tracts of ground. 
 
 3. The favorable contour of most of the surface, which will enable 
 large bodies of the west lodes to be taken out from short adits, 
 without artificial drainage. 
 
 4. The unusually rich character of the surface rock at the 
 outcrop of the west lode No. 1, wherever opened; so much unalter- 
 
15 
 
 ed galena and copper pyrites being found, in addition to the goz- 
 zans, which are universally believed to indicate an increase of met- 
 als in depth, below water level; and the important chemical reasons 
 given above for believing tha* at this place the gozzans represent 
 chiefly copper pyrites. 
 
 5. The generally argentiferous character of the galenas of this 
 section of the United States, some of them having been found by Dr. 
 Jackson and others to contain as much as two or three pounds of 
 silver per ton. 
 
 6. The increased value given to ores of this character by the 
 numerous and important improvements, made in recent times, both 
 in the modes of concentration of the ore, and in the modes of 
 extracting their various metallic contents. 
 
 In conclusion, I desire to expross my most emphatic approval of 
 the policy, too seldom followed by proprietors of mineral localities, 
 which has, however, in the case of your property, been wisely and 
 conscientiously adopted, of instituting competent Loientific explora- 
 tions and examinations of the locality, before initiating or inducing 
 heavy expenditures in the way of mining operations. 
 
 Such investigations, now in progress, will, without doubt, lead to 
 the saving of much money in the end, this being, in fact, proved, as 
 I may confidently claim, by the developments already made. 
 
 All of which is respectfully submitted.

 To the New Hampshire Silver-Lead Company: 
 
 Gentlemen — Professor H. Wurtz has placed in my hands, for 
 assay, tliree samples of galena, which were collected by him per-

 I find them to give the following results:

 Yours respectfully, 
 
 JOHN TORREY, 
 
 United States Assayer. 
 
 Eemarks upon the Results of the Assays. 
 
 The samples No. 1 and No. 2 were botli from the West Lode, 
 No. 1; sample No. 1 being from the opening B, near the hanging 
 wall; and sample No. 2 from the opening A, further uj) the hill and 
 near the foot wall. 
 
 The reason Y,\\y they were assayed separately, was the observa- 
 tion that they differed perceptibly in color and lustre. No. 1, 
 from near the hanging wall, being of a darker blue color, and 
 higher lustre than No. 2. It appears that the darker and more 
 brilliant variety contains 56 per cent, more silver than the other. 
 The practical value of this important observation will appear here- 
 after in the working of the mine. 
 
 The value of the silver in one ton of 2,240 lbs. of the dark vari- 
 ety of this galena is, in coin, at $1. rVA per oz., the standard value, 
 
17 
 
 $72 24 — equal, at present rate.«, in currency, to about $180. Pure 
 galena contains 86.6 per cent, of lead. Supi osin,<>- this to yield 80 
 per cent., the value of the lead in 2,2-iO lbs. at 15 els. per lb., (its 
 present value,) is $280; making the total present value of the metal 
 in one ton of this galena $450. Making the same calculations with 
 regard to the other samples, and reducing the metallic lead upon 
 which the assay was made, in the case of the Orchard Vein, back 
 to the form of galena, we have the following table:

 The most interesting result here is, that, notwithstanding the im- 
 portant quantity of gold in the Orchard galena, the superior rich- 
 ness in silver of the dark galenas, from the hanging wall side of 
 the west lode, brings the value of the metals in the latter very 
 nearly up to that of the Orchard Vein. 
 
 The discovery of gold, for the first time, in this part of New 
 Hampshire, and in such important quantity, is of great interest, 
 and encourages further examinations of the rocks and minerals 
 upon your property for this metal. 
 
 The suggestion to assay these galenas for gold as well as silver, 
 was made by me in consequence of the striking resemblance of this 
 belt of talcose schists and its Included veins to certain belts of the 
 same rock, and their included veins, in the gold regions of North 
 
18 
 
 Caxolina. Slight indications of gold have previously been found 
 in New Hampshire, in Canaan, Enfield and Grafton townships, in 
 the southern part of this same County of Grafton, by Dr. Jackson, 
 in magnetic pyrites; and at Bridgewater, Windsor County, Ver- 
 mont, in small quantity, in quartz, associated, as iu this place, with 
 the sulphurets of iron, copper and lead.

 Gentlemen — Renewed exaraination of your mining property on 
 Gardner's Mountain, in New Ilanipshire, and tlio further develop- 
 ments made since my former visit, enable me now to report as 
 follows: 
 
 An apparent misunderstanding of the recommendations made by 
 me at my first visit has occasioned some delay in developing the 
 outcrop of West Lode, No. 1, and some expenditure not altogether 
 necessary in the present stage of the undertaking, although it may 
 be that in the end this expenditure will not have been unprofita- 
 ble. The imperfect developments of the outcrop of Lode 1, that 
 have so far been made, lead me to present the sectional sketch ap- 
 pended hereto, which is partly founded upon actual appearances, 
 and is partly conjectural; so far as it is conjectural or ideal, this 
 rough sketch will serve as an illustration of the general structure 
 of such mineral countries as this in which your lodes arc found. 
 The section is supposed to be made through the excavation into 
 the outcrop, looking towards the S. W., the line C D E F repre- 
 senting the surface of the country along the slope of the mountain, 
 D E; the outcrop of Lode 1, the dotted line D E F G, approximat- 
 ing to the outline of the excavation at my last visit. Of course 
 everything represented in the drawing below this line is ideal. 
 A B is the " country " composed of a talcose quartzite schist; the 
 laminae of talo being represented by the black lines» At the 
 
place wlicro the oxcavatiou is licin^- made it. linpiicnod that a con- 
 8i(lcrril)l(» number of irro^rnlmly fonncd brda of tlio country rock 
 itself ore endowed in \hv lodv of tin' Lode, consliluliiig what is 
 technically called a " horse." 'J'his jior.e, thou^^h c(mtaining in 
 many places, like the cf)untr\ nick, much niundic, is nearly bar- 
 ren of ore, and even of >,'<)zzanj? and other indications of the pre- 
 vious existence of ore; and even the irren;uh»r branches of the Lod(! 
 itself, which penotrale in places between the ramifications of the 
 horFO, arc much decomposed and less rich in indications than the 
 more compact portions of the Lode at the surface. At the point 
 of greatest penetration into the hill, however, the excavation seems 
 to have ])assed beyond the horse, as at E, where the Lode appears 
 again to bo compact, as on the surface, and shows bunches of lead 
 and copper. At this place the wall limiting the ore-bearing portion 
 of the Lode appmrs to dip into the hill. This wall, however. I 
 regard as simply the inner wall of the horse. In depth I should 
 rc;»:urd it as almost a certaintv that the Lode would soon be found 
 to re-assumo its original dip, and that, moreover, the horse, like 
 other liorscs in veins, would be foaud in depth to thin out and dis- 
 appear below, as it plainly docs ubov.'. iho Lode becoming again, 
 as represented at K, compact and Jiighly metalliferous, as it is at 
 the surface. The persistence in magnitude and metalliferous char- 
 acter of these Lodes, throughout so great a longitudinal extent, is 
 sudicicntly satisfactory evidence that the same persistence will be 
 found in depth; at the same time it cannot be doubted that these 
 Lodes will be found to throw off l)ranches, both longitudinally and 
 vertically, and the schists will be "lf)i|mea to enclose lenticular 
 masses of metalliferous quarlz. such a- that ideally reprr>senied nt 
 L, which thin out both in length and depth. In places, these ion- 
 ticular beds are found coming to the surface and cropping out, bc- 
 twc8;i the outcrops of the great Lodes themselves. The red lines 
 drawn across tbr^ ^.ode are iatroducod for the purpose of indicat- 
 iag a peculiar tstrrcturt hf thc^ Lodes, which careful examination

 well as the strings and bunehts of or' itrocceding from then will 
 he found in some cases to penetrate beycnd the foot-wall boundary 
 oi the Tiode, into the talcosc countiy ben ,th. These layers form 
 a bcries of cleavage jdanea pervading the mass of the Lode, whi* h 
 will no doubt greatly facilitate the sto])ing md breaking out ci' 
 the vein-stone; soraetinies these planes pus,- through the horse, 
 though usually displaced and distorted by it. T'le same system ol 
 ]danes was found strongly d('velop(>d along th' outcrop of Louo 
 No. 2. It is extremely i>robable, therefore, thai this curious and 
 peculiar variety of vein-structure will be fonn 1 to boa feature of 
 the metal-bearing Lodes of this section. 
 
 1 wish here to ofler a few suggestions which s om peculiarly 
 apjdicable to the ease of your mining properly. In (Derating upon 
 such large lodes as these, it seenu^ to mc that a very favorable 
 opportunity is presented to test the applicability (wl ich, however, 
 can scarcely be doubted) of the improved forms of drilling ma- 
 chines, now in such extensive nse in tunnelling oj»era(ious. Such 
 machines, operated by compressed air, would be of peculiar value 
 in mining operations on a large scale, for breaking out the galleries 
 of thr mine, as their use, liesidcs the immense saving ol' labor and 
 time, would obviate the heavy expense of sinking air shafts in 
 many places for ventilation. This would be i)articularly the case, 
 w«'re the blasting accomplished by means of cartridges charged 
 with gun-cotton, which makes i:o smoke, in lieu of the common blast- 
 ing jiowder. 
 
22 
 
 In conclusion 1 will remark, that my favorable impressions as to 
 the value of your mining property, as set forth in my first report, 
 remain unaltered. 
 
 All of which is respectfully submitted.

 Lewis A. Osborn, Esq., New York: 
 
 My Dear Sir — I have been to tlie Lyman Mine again since 
 I saw you, and put in some blasts — a part of the specimens I for- 
 ward to you; most of these specimens came from the West Vein that 
 has been discovered to this date. This vein, I sliould say, is about 
 twelve feet wide, running about 40° East of North, with a dip to 
 the S. E. about 45°. The rock beside the vein is a granular quartz, 
 with some felt spar and lime intermixed with it. About 100 feet 
 east from this vein there are strong indications of another vein; 
 300 feet cast from the west vein, so called, there is a large vein, tlie 
 outcrop or gozzan is some eight to ten feet wide, and the sulphur is 
 oxidizing through the vein, giving very strong indications of a large 
 champion vein; the iron pyrites form in fissures, as it always does 
 in these champion veins. 400 feet from this vein I discovered 
 another vein, running just in the same direction as the former ones. 
 I should say this vein is about two feet wide. About 120 feet cast 
 from this vein is the Orchard Vein, that was first discovered by 
 sinking a well for the farmhouse; this vein is from two to three 
 feet wide, containing quartz, with good spots of lead within 
 a few inches of the surface. The country beside the vein is of 
 granular quartz, lime and slate. The course of the vein is about 
 80 degrees E. of N. It underlies alout one foot in a fathom, or say 
 about 70 degrees toward the S. E. You ask for my opinion about 
 the mine. I have had about thirty years' mining experience, and I 
 have done considerable exploi'ing in this country, also in Cornwall 
 and Devon, England, but 1 never before took so rich a lot of speci- 
 mens so near the surface as I took from the West Vein on your prop- 
 
24 
 
 crty. You can see the nios.^ on the outside of one of these specimens, 
 and as soon as the rock was broken there was the silver-lead. You 
 also can sec another stone that came out with the same blast, about 20 
 inches long, and a\)oufc H by 12 the other way — more than one-third 
 is silver-lead; it is aldo full of vug-s and fissures, as all good lodes 
 show themselves. A.s the vein now appears, it would pay all it 
 would cost, to work as soon as you get tools and machinery. As 
 to the adjoining vein, there has been nothing done, so I cannot say 
 anything about it, except that the surface indications are excellent. 
 The large Gozzan Vein, 1 think, will be the best vein on your prop- 
 erty, although it does not show the ore — there are the indications 
 unmistakable. The next vein you have not as yet seen; it looks 
 promising, but nothing has been done on it yet. The Orchard Vein 
 you have seen; the work has been limited, as I wanted to return 
 home; but there has been good samples taken from it; you took some 
 with you; also, Mr. A. J. Walker and others. As regards my 
 opinion, I think you own one of the best mining properties that 
 I know of, and where everything for mining purposes may be ob- 
 tained cheap; lumber about |8 per thousand, wood $3 per cord; 
 labor as cheap as any place in the States; distance from railroad 
 depot about 5^ miles, with a good road, and conveniences in gen- 
 eral very good. I consider your mining district a very valuable 
 
 one.
