REPORT ON THE SYDNEY COLLIERY.

I. — THE SYDNEY COAL FIELD.

Contrasted with the disturbed and faulted coal fields
of Great Britain, the Sydney measures display remarkable
uniformity and great regularity in structure. The disloca-
tions appear to be almost exclusively limited to the deep
inlets and bays on the coast, which all have a roughly parallel
direction towards the North East by East.

The Great Bras d*Or, Little Bras d'Or, Spanish Bay,
(Sydney Harbour), Indian Bay, Glace Bay, and Cow Bay, all
appear to mark the course of up-throw or down-throw faults ;
but the intervening spaces are, as far as known, free from any
important disturbances. In this respect the Sydney measures
differ in a marked degree from those of Pictou, where great
cross faults are met with.

Perfect regularity appears to exist in the measures
between the Little Bras d'Or and Sydney Harbour to the
north and south of the Sydney Colliery ; the average inclina-
tion or dip is not more than seven degrees, and towards the
east, north-east, (N. 6oE. ; see Plan and. Section.)

The thickness of the coal measures between their base
at Stubbard's Point, Sydney Harbour, and Cranberry Head,
is 1, 860 feet, the horizontal distance between these points
being about 5,000 yards. The whole of this section has been
carefully measured by Mr. Richard Brown, and the details are
given in the Proceedings of the Geological Society of Lon-

The thirty-seven feet of coal is made up of thirty-one
seams ; and of these Mr. Brown states that four only are
of sufficient thickness to be worked profitably. These are : —

No. 2. — Main Coal 6 o

No. 3. — Lloyd's Cove Seam 5 o

No. 4. — Cranberry Head Top Seam 3 8

Since Mr. Brown's paper was written, it has been ascer-
tained that the seams thicken towards the north ; hence it
may arise that some of the beds of coal enumerated in his
section, and then considered too thin to be profitably worked,
will in their northerly extension become of considerable
economic value.

Three of the seams mentioned in the foregoing list have
been worked by the General Mining Association ; viz., the
Indian Cove Seam, the Main Coal, and Lloyd's Cove Seam.
In consequence of the superior quality of the Main Coal, the
other two seams have been abandoned for some years and the
works concentrated on the Main Coal, from which upwards of
one hundred thousand tons have been excavated during the
past year.

The Colliery of the General Mining Association, which
lies to the south and south-west of the Sydney Colliery, gives
employment to about five hundred officers, men, and boys ;
and having exhausted a considerable portion of the land area,

Sydney Colliery. 7

its works for some years past have been extended under the
sea on both sides of the Cranberry Headland. The Sub-
marine Works in Lloyd's Cove now occupy over thirty acres,
and stretch upwards of a third of a mile under the sea, and
those on the opposite coast cover twenty-four acres under the
sea, and are expanding in a northerly and north-easterly
direction. The quantity of coal raised from the Submarine
workings in 1870 amounted to 66,224 tons.

2. — CHARACTER OF PRESENT SUBMARINE WORKS.

The General Mining Association, as already stated, have
extended their works over an area of thirty-two acres under
Lloyd's Cove, and about twenty-four acres under the ocean,
between Cranberry Head and Black Point. The extraordi-
nary dryness of these Submarine Works shows conclusively
the impermeable character of the roof; for, on the Lloyd's
Cove side of the Peninsula, at a distance of one-third of a
mile under the sea, the mine is dry ; there is no accumulation
of drainage water, and the walls of the drift are not wet.
Evaporation, heightened by the temperature (about sixty-four
degrees), and the ventilating current of air, suffice to keep the
mine comparatively dry. There are no indications of faults
or regular displacements of the strata, although slight and
wholly unimportant irregularities in the seam are met with in
three or four places, and on lines roughly parallel to one
another. These irregularities consist of narrow depressions
in the seam (nips), and a corresponding bulging out on each
side of the nip.

The roof is in some few places fragile to the extent of
the thickness oT the bed of shale (from two to six feet), which
immediately overlies the coal, and sometimes it is found
advisable to support the shaly roof for a few square yards, or
remove it until the strong, persistent Sandstone, twenty-four
feet thick, is exposed to view.

The floor of the Main Seam is an underclay, eight feet
thick. No evidence of creeps have yet been observed in the
mines of the General Mining Association, notwithstanding

the coa'. is partially worked out, according to the pillar-and-
board system, over an area covering considerably more than a
square mile.

3. — ROOF BETWEEN MAIN SEAM AND LLOYDS COVE SEAM.

Immediately above the Main Seam is an Argillaceous
Shale, varying in thickness from two to six feet. This is
overlaid by a massive bed of strong Sandstone twenty-four
feet in thickness. Succeeding the Sandstone, alternating
beds of Argillaceous, Arenaceous, and Bituminous Shale,
occupy a vertical height of seventy-two feet, and are over-
laid by another bed of strong Sandstone twenty-one feet
thick, Ninety-seven feet of Shales and Sandstones follow,
which are capped by a Sandstone bed forty-seven feet in
thickness. Succeeding this Sandstone are one hundred and
forty-two feet of alternating Sha'es and Sandstones, in which
some of the arenaceous beds attain a thickness of ten and
fourteen feet, — the whole being surmounted by a bed of
strong Sandstone thirty-one feet thick. An intervening
breadth of thirty-seven feet of Shales is followed by another
thick bed of strong Sandstone, measuring forty-one feet,
above which are two hundred and nine feet of Shales and
Sandstones, on which the Lloyd's Cove Searn, five feet in
thickness, rests. The entire thickness of the strata between
the Main Seam and the Lloyd's Cove Seam is seven hundred
and twenty-three feet, in which are no less than seven massive
beds of Sandstone having the following thicknesses respec-
tively : —

and Sandstone succeed, followed by a bed of Sandstone ten
feet thick. A mass of alternating Argillaceous Shales and

In the absence of dislocations, and with a roof nowhere
less than seven hundred and fifty feet in thickness, and
composed of numerous thick bands of strong Sandstone
between beds of Arenaceous Shale, the influx of sea water
becomes almost impossible, and explains the reason why the
Submarine workings of the General Mining Association are
so unusually dry. Of course it is understood that the drain-
age waters from the old works to the rise are kept back by
barriers, the lowest one being sixty feet in thickness.

6. — VENTILATION IN THE SYDNEY COLLIERY.

The furnace is used by the General Mining Association
as a means of ventilation. The recent improvements in fans,
and their application, to a large extent, in Europe, make it a
matter for consideration whether their introduction in the
Sydney Colliery would not be attended with considerable
advantage. Their great capacity, economy and safety, and the
capabilities they possess to ventilate remote workings, will
probably ensure their adoption in this Colliery. The utmost

Sydney Colliery. II

limit of the Sydney Colliery, on the direct line of dip, is not
more than three miles, and submarine works have already been
carried nearly to that distance in England. At right angles to
the dip the limits of the Colliery considerably exceed two
miles ; but, as stated on the best engineering authority in
England*, the fan machines are capable of ventilating as deep
as mining is ever likely to be prosecuted, and their capacity
for horizontal work is far in excess of any requirements likely
to be made in the present generation.

The economical advantages of mechanical ventilation have
been recently discussed in a paper read before the North of
England's Institute of Mining and Mechanical Engineers, by
Mr. D. P. Morison.

The results are stated to be as follows : —

I St.- -A saving in the consumption of fuel, in most cases,
from 40 to 80 per cent, in favour of mechanical ventilation.

2. — The inapplicability of the furnace system to satisfy
the demand on the occurrence of sudden emergencies.

3. — Economy in the wear and tear of plant.

Among the various fan machines for ventilating, Mr.
Morison expressed himself in favour of Guibal's, the one
most in use in England and the Continent of Europe.

7. — MODE OF MINING THE COAL IN THE SYDNEY COLLIERY.

In planning the works for this Colliery, regard will be
had to all surrounding and collateral conditions. Among the
most important of these are the established character of the
coal in the market, and the impossibility of committing the
error, which in some instances has been fatal, of sending
into the market at the outset " crop coal." It is well known
that great injury has been done to the mining interests of the
Northern Cape Breton coal-field by sending into the market
coal from so near the crop of the seams, that all the impurities,
accompanied by the deterioration which results from exposure
to atmospheric influences, characterized the first samples. A
desire to obtain quick returns has for a long period greatly

12 Report on the

damaged some of the Collieries in Cape Breton, and the crop
coal thus sold has fixed for a time the character of a Colliery
greatly to the loss of the owners*.

The plan adopted by the General Mining Association in
their Submarine Works, is that of the Bord and Pillar.
Experience in England shows that this plan is the safest. In
the diagrams representing the method of working the Sydney
Colliery, the liord and Pillar system is shown. The remark-
able regularity of the measures, as far as known, seems to
leave no doubt that the coal can be worked uniformly to the
rise, as represented on the plan ; this is the most economical
method, and although with a proper barrier, hereafter noticed,
there is no reason to apprehend any trouble from water, yet
by working to the rise, the introduction of self-acting inclines
will considerably economize labour.

8. — DRAINAGE.

The barrier indicated on the plan is 200 feet broad. Its
object is to cut off all the drainage waters from the land, and
from possible future workings south of the limits of the

♦ In other cases searas have fallen into disrepute on account of either igno-
rance of the peculiar characters of different parts of the seam, or when these are
known, of carelessness in separating the good from the indiflferent portions.
The main scam of the Sydney Mines is generally very uniform in quality, so
that the precautions necessary in some seams in northern Cape Breton do not
apply here. It is a significant fact, however, that with every desire to send the
best (jualities of coal into the market, yet, from a want of that information which
a chemical analysis would supply, consumers have been supplied with coal
unsuitable to their special requirements. There is, for instance, in the Sydney
Coal P'icld, a scam long celebrated for its adaptation to produce illuminating gas
of e.\ceilent quality. Experience showed that while its properties were very
favourably spoken of by one class of consumers, others complained of the
amount of sulphur it contained. Analysis showed that a portion of the seam
was almost free from sulphur, while other portions above and below contained a
considerable but not unusual proportion of this detrimental substance. It is
probiible also that in this seam the amount oi sulphur is variable in different
parts horizontally as well as vertically.

In 1S66 Mr. Rutherford drew attention to this injudicious practice in his
Official Report for that year.

Pillar working. — The facility with wuich the coal has been reached in all

Colliery. The only breaks in this barrier will be those of the
Main Dip Road from the Kngine Pit at Honar Head, and at
some future time for air shafts to the north and south of the
Engine Pit, as the workings extend in those directions.

The Sydney Coal is remarkably free from fire-damp (Car-
buretted Hydrogen). By this expression it must not be
supposed that there is no fire-damp, or that miners can work
at all times with impunity. It is rather to be understood
that with ordinary precautions no accidents are to be feared
from the presence of this gas. A perusal of the Inspector's
Reports sufficiently establish this point.* In speaking of the
Sydney Mines, the Inspector says : — " Carburetted Hydrogen
is found in the mines, but not to any extent." Some acci-
dents have occurred from local explosions of the gas in old
workings, but in all cases these have been traced to great
want of caution on the part of the sufferers.

the districts, as compared with other mining countries in which, from the exhaustion
of the seams near the crop, expensive sinkings become necessary to reach the
underlying coal, and consequently great skill and carefulness are required in pro-
perly opening out the mine ; this freedom from an expensive preliminary outlay,
instead of enabling an effective winning of large tract of coal to be made before com-
mencing the regular working thereof, seems to have engendered an indifference to
future operations, and allowed the desire for an immediate profit to supersede the
necessity of a judicious arrangement of the mode of working. To this cause I
attribute the short distance from the crop, to which in most of the mines the
workings are confined ; and the adoption of a system by which as much of the
seam as possible is taken away in the first working and the pillars are reduced to
a minimum of strength for the purposes of support. The injudiciousness of this
system cannot be too strongly urged. The introduction into the market of coal
worked so close to the crop must have operated prejudiciously — and I have
reason to believe that it has — to the interests of the mine owner ; and the con-
tinuance of the scale of pillarage, which has, I think, from the preceding cause
been too generally adopted, will be fraught with consequences of a more serious
character. For, although with the present limited extent of workings and the
absence of pressure in consequence of the proximity of the coal to the surface,
the pillars may be sufficient to keep the mine open to ventilation or other pur-
poses, yet if unaltered where the overlying strata are very much thicker and
heavier, their inability to support will in no long time be exhibited to the serious
detriment of all concerned. For this reason I have felt it my duty to recommend
an increased size of pillars as the workings extend to the dip, with a view to
their subsequent entire removal.

14 Report on the

9.— AVAILABLE COAL FROM THE MAIN SEAM OF THE SYDNEY

COLLIERY.

The average thickness of the Main Seam is six feet ; it
varies by two or three inches in long distances, being some-
times in excess and sometimes in defect of that average. It
has been already stated that, at rare intervals, "nips" have
been observed in the mine of the General Mining Associa-
tion, squeezing the coal over a narrow space, and causing it to
bulge at the outskirts of the "nip." An important " nip" of
this description occurs two-and-a-half miles west of the
Queen's Pit, and about one-and-a-half miles south from the
Engine Pit of the Sydney Colliery; this "nip" was at first
thought to be a small fault, but the continuation of the out-
crop of the seam, in its regular course to the north, makes it
more than probable that it is a local " nip." In estimating
the quantity of available coal, the average of six feet is
assumed.

Considering one cubic yard to represent one ton, the
amount of coal contained in each square mile of the Main
Seam is equal to 6,195,2000 tons. In the first workings of
the Sydney Colliery, the proportion of rooms to pillars is
assumed at one to two, or one-third available coal in the
rooms and two-thirds to remain standing in the pillars.

With this ratio existing between the Bords and Pillars,
the quantity of available coal per square mile from the Main
Seam would be two million and sixty-five thousand tons
(2,065,000.) A radius of one mile from the Engine Pit
would command three million two hundred and forty thousand
tons, leaving six million four hundred and eighty thousand
tons standing as pillars.

It will be observed that this calculation is based on the
very unusual proportion of one-third available coal and two-
thirds in pillars. In consequence of the Colliery being
Submarine, the proportion left standing in pillars must con-
siderably exceed the pillaring in ordinary works of the kind,
but there is every reason to suppose that a considerably larger

Sydney Colliery. 15

amount may be withdrawn than the ratio given above. One-
half the coal left in pillars would leave for extraction : —

In one square mile — Available coal 3,097,600 tons.

" " In pillars 3,097,600 "

In a radius of one mile from Engine Pit — Available coal. 4,860,000 "

' " In pillars 4,860,000 "

Total main coal on the property 91,000,000 tons.

Deducting the barrier, the superficial area of the coal in
the Main Seam within the limits of the Sydney Colliery,
exceeds twelve square miles. A considerable proportion of
this large area will be worked from Cranberry Head, on the
same system as indicated for Bonar Head. (See plan). It is
impossible to enter into details respecting the best mode of
mining the coal in the Cranberry Head Section. It is not
probable that attempts will be made to win the coal there for
many years to come, and, in the interval, the works of the
General Mining Association will have exhausted a large por-
tion of the coal belonging to that corporation, and the future
operations of the Sydney Colliery will depend upon the nature
of the works carried on by the General Mining Association
in the Cranberry Head District. In case the proprietors of
the Sydney Colliery were to commence works for mining the
coal in the Cranberry Head Section, the plan of operations
would be identical with those at Bonar Head, for all the
conditions are similar. The roof, the dip, the seam of coal,
all present the same physical outlines, and, as far as known,
exactly similar conditions of occurrence.

10. — COAL-CUTTING MACHINERY,

The commencement of a new Colliery of the first class in
Cape Breton, where no old associations or prejudices interfere
with the introduction of the best artifices and means to attain
the end in view, which modern science and experience
suggest, affords the best opportunities for working with the
utmost economy in all particulars.

Many of the objections to the general use of coal-cutting
machinery are to be traced to prejudice, and opposing inter-
ests. Ample proof exists that simple and effectual coal-
cutting machines are now in operation in Europe, which will

1 6 Report on the

effect a saving of fully one-half in getting out the coal. The
saving is of a threefold character* : —

I St. — Safety, by avoiding the use of gunpowder.
2nd. — The less amount of slack obtained.
3rd. — The saving in labour and time.

The Grafton Jones' coal-getting machine is described as
" pushing coal out of the solid, without any holing or natural
breaks in the seam, at Keverton Park Colliery, in South
Yorkshire. The seam is five feet thick, and the coal is very
hard ; but by the use of the hydraulic wedge, blocks are got
four yards long and four feet wide — each about eight tons
weight — at one application of the machine."!

The getting out and underground storage of large masses
of coal are of the utmost importance in the climate of Cape
Breton. The Government Inspector has called special atten-
tion to the great loss which ensues from the accumulation of
coal above ground during the winter months, and its deteriora-
tion from exposure to the severities of the climate of Cape
Breton during the inclement season of the year. So great
has been this deterioration, that in some instances the In-
spector estimated that not much more than fifty per cent of large
coal had been obtained from this heap in some of the mines.
The Inspector's remarks and suggestions are contained in the
subjoined foot-note$.

* See a paper read before the North of England Institute of Mining and
Mechanical Engineers — Glasgow Meeting — by Mr. Arnold Luplon, on " Grafton
Jones' Coal-getting Machine."

t Storage of Coal. — It may perhaps seem premature to cry " waste " at
so early a stage of mining as the very recent development of the mineral re-
sources of this country implies ; but, at a time when attention is being directed
in England to the exhaustion of her coal supplies, and the consequent necessity
of economising them by every available means, it cannot, I think, be considered
inopportune to direct attention to a source of waste which may with care, to
some extent, be lessened.

In many of the Collieries the greater part of the slack made in working is
separated from the large Coal by riddling, and thrown aside in the mine. The
proportion thus taken out varies from five to twenty per cent. This slack is

1 I. — CHARACTER OF THE SYDNEY COAL.

" The character of the coal of the Sydney Mines has been
well known in the market since the commencement of opera-
tions by the General Mining Association, in 1827. It is

seldom removed, and has therefore largely accumulated. It is reasonable to
suppose that if it could be sold even at a very small profit, it would not be left in
the mine ; and it is thus treated to avoid expense of depositing it on the surface,
and the combustion that would probably occur if a large quantity were heaped
together. By attention to the peculiarity of each seam, and the manner in which
the miner performs his work, the proportion of slack made in the ordinary
course of working may be reduced, and the loss of merchantable coal from this
cause be diminished. But there is another source of loss to which, inasmuch as
it affects the revenue to a much greater extent, I wish to draw attention. I
allude to the large stores of coal that are formed during the winter months.
The suspension of shipment for a period of from three to four months necessi-
tates the adoption of one of two courses : either the Colliery must be stopped,
or be continued at work and the coal brought out and stored on the surface.
It must be evident: that in the former case both employers and workmen would
be subject to much inconvenience and loss : the workmen would be obliged to
seek other means of employment, and the mine owner would be unprepared to
commence operations on an adequate scale when the shipping was resumed.
For this reason the latter course is adopted, and the consequence is a deteriora-
tion of the coal from exposure, and the production of a large proportion of slack
both from this cause and from the breakage in putting down and relifting. To
such an extent does this take place, that I have reason to believe that in some
instances the produce of large coal from the heap has not much exceeded fifty
per cent. When it is remembered that a large percentage has already been taken
out in the mine, and that the coal brought to the surface is with respect to size in
nearly a merchantable state, the loss of revenue from this cause must be ap-
parent. Impressed with the importance of obviating this as much as possible, I
have endeavored to induce the adoption of some means by which this loss may be
reduced to a minimum, and I am hopeful that as the interests of the mine owner
are seriously affected by so small a yield of saleable coal, they will readily adopt
any practicable scheme for realizing so desirable a result. This would, I con»
ceive, be to a considerable extent accomplished by an extension of the power of
production by a judicious laying out of the mine, and the formation during the
winter of a number of working places, together with the opening of more shafts
or other means of bringing the coal to the surface. With such a provision much
of the coal might be stored under ground and be raised as required without
interrupting the ordinary working of the Colliery. The injury to that portion
which would be sent out of the mine would also be very much less if suitable
erections were made for protecting it from the weather. There are details of
arrangement in carrying this out which it is unnecessary to state here ; I make the
suggestion with the hope of drawing the attention of owners and managers to the
importance of devising some means of lessening a loss by which the interests of
all are effected." Inspector's Report^ 1866.

" The details above given explain the well known high
favour- in which this Coal has been held for upwards of forty
years for domestic use, and also for steam producing by those
who have employed it carefully."

In i860 the Inspector reported, "It may be interesting
to know that a cargo of 450 tons of this Coal was shipped by
order of the French Government to Brest

The Director of Naval Construction at Brest reports the
result of the trials made upon it to the Minister of Marine, as
follows : — The trials of the Nova Scotia coal by La Perdrix
show that, like Newcastle coals, it ignites easily, and produces
a long, lively flame, little coloured. It swells a little in the
fire and does not clog the bars. It gives but little clinker,
and is not very brittle.

The steam power is little inferior to that of Cardiff coal
and equals that of Newcastle. It is a fine coal and completely
assimiable to that of Newcastle ?"

The whole number of calls of steamers, including French,

20 Report on the

English and American men-of-war for coals that year was
sixty six*.

At the present juncture this evidence of the steam pro-
ducing capabilities of the Sydney Coal from the Main Seam
is very important, in consequence of the gradual introduction
of Coal as fuel for Locomotives.

The experiments conducted under the supervision of the
late Mr. Hartley, Mining Engineer to the Geological Survey
of the Dominion, show conclusively that the steam coals of
Nova Scotia are well adapted not only for Marine but also
locomotive use. This fact has long been known with regard
to the Sydney Main Seam as appears from the foregoing quo-
tations from the Director of Naval Construction at Brest, and
the constant use of this coal on war and other steamers.
Its extension to the Pictou coals will draw attention to the
one question which remains, namely, the cost at which the
Sydney coal can be delivered at certain points compared with
the Pictou coals.

The construction of the Furnace both of steamers and
locomotives, and doubtless in all application of Coals of the
Newcastle or Sydney class, is of immense importance in order
to obtain the greatest efTect. In a series of trials recently
made at Portsmouth with new and old Furnaces on board
vessels of the Royal Navy, the following remarkable results
were obtained : —

"From these trials it appears that the new Furnaces ex-
hibited a saving upon the old, of 14.28 i>er cent, in fuel, an
increase of 7.56 per cent, in horse power, anc^ a positive gain
in the consumption of smoke, of 21.84 P^"^ cent.

The general introduction of Coal for locomotive use is not
far distant, it is now used more or less on the Nova Scotia
lines, and it is found to be more economical in several ways
than wood. (Vide Mr. Hartley's Report page 41-42.)

12. — RAILWAY AND LOADING GROUND.

The length of Railway constructed by the General Mining
Association from the New Winning to the Loading Ground
at North Sydney is about four miles. The distance from the
Engine Pit of the Sydney colliery to the Loading Ground at
North Sydney is about 5^ miles, but in case the mouth of the
Little Bras D'or should be selected at the Loading Ground
the distance would be about two miles only. In view however
of the great advantages possessed by Sydney Harbour it is
probable that the Loading Ground will be situated on some
convenient part of this safe, capacious and well-known ship-
ping place.

A narrow guage Railway similar to many now constructed
for Mining purposes in Europe will amply suffice for all the
requirements of the Colliery even supposing the yearly out-
put reaches 200,000 tons. Stationary engines are now
employed for similar purposes in Europe and are more econo-
mical than locomotives.

• 13. — CONCLUSION.

Bearing in view that the physical features of the country,
the capabilities of the harbour, the regularity of the measures,
and the exceptional quality of the coal, are all of a highly
favourable character, it is sufficiently evident that all the
elements for the establishment of a first-class Colliery exist at
unusually low cost for preliminary work. The subsequent and
not less important items connected with the underground
operations are under complete control, as far as such opera-

it Report on the

tions can be predicated, and may be briefly enumerated
under the following heads : —

I. — Ventilation. — By means of Guibals, or other approved
machines.

II. — Drainage. — By the preservation of a barrier 200 feet
broad at the outset, to cut off the water from the rise ;
thereby reducing the pumping service to a minimum.

III. — Storage or Coal. — By the use of Coal-cutting
machines to take out the coal in large blocks and store
it underground during the season of suspended naviga-
tion.

IV. — Getting the Coal. — By means of Coal cutting ma-
chines, in order to economize labour, time, and loss in
slack, as well as to ensure safety.

It is not unreasonable to state that by the adoption of

these artifices the cost of a ton of Coal from the Sydney

Colliery, placed on board a vessel at the loading ground, will

fall considerably below the cost at which a ton of Coal of

equal quality has ever been shipped either in Nova Scotia or

Cape Breton.

conticirous thcrrto, and no agreement can he made for the j)iirchase thereof, it
Hhnll l)c lawful for the iJirectors to apply by |>ctiti<)n, with a plan annexed, to any
enu of the Judges of the Supreme Court, setting forth the nature and situation of
the lands required, the names of the owners or occupiers thereof, and praying a
conveyance of the same to the Company, whereupon such Judge, being satisfied
that the lands arc rcciuircd, and arc not more extensive than may be reasonably
necessary, shall appoint a time and place for the consideration of such petition,
and shall direct a proper notice in writing to be served upon the owners or
occupiers of the lane's, if in the Province, and to be published for one month in
at least two newspapers published in Halifax, and also in one newspaper (if any)
of the County wnere the lands lie, reciuiring them to attend at such time and
place personally or by Attorney; and tne Judge shall require the Directors to
nominate one appraiser, and such owners to unite in naming one appraiser ; and
the Judge shall nominate a third appraiser, but in case such owners do not at-
tend, or shall neglect or refuse, or cannot agree to make such nomination, the
Judge shall, on proof of such publication or service of such notice, nominate two
appraisers, and shall, by order in writing, direct such three appraisers to value
the lands so required, and the appraisers having first subscrioed an affidavit in
writing, to be sworn to before a Justice of the I'cacc, and annexed to such order,
to the effect that they will faithfully make such appraisement, shall, with all
convenient speed, proceed to and appraise such land, and shall make such ap-
praisement in writing, and return it under the hands of the appraisers, or a
majority of them, with such order and affidavit, to a Judge, who may confirm,
modify, alter or reject such appraisement, or direct an appraisement de novo ;
and the Company, upon tendering or paying the amount of the appraised value,
as finally confirmed, and the expenses of the owners on snch appraisement to the
owners, or, in case of dispate, to such parties as the Court or a Judge shall direct,

Court of Sessions, to ensure the safety of the inhabitants and their property.

11. The Company may proceed either alone or with any other Company to
render navigable any harbors, lakes or rivers, by deepening, widening or extend-
ing the channels, or by opening a new channel or channels. They may erect
piers, breakwaters and shipping places for coal upon any lands owned by the
Company, or acquired, as herein provided, or upon any lands of the Crown, in
respect of which permission shall be granted by the Governor in Council, in and
about the shores of such harbors, lakes or rivers. The portions of such harbors,
lakes or rivers thus rendered navigable shall be open and free for the use of all
ships, vessels and boats, and to all persons desirous of using the same for trading
purposes, subject to such tolls and regulations at such rates as shall be fixed by
the Company, and approved by the Sessions of the Connty.
