One plan of working out coal may answer well in one
mine, but not in another; because the nature of the
roof, floor, and coal, is not alike. At mine the
floor is SOFT and hard at another. In other mines the
roof and floor both soft in others both hard The
floor heaves Fuckers up in some Mines but not in
others; in some mines the coal is very thick; in
others very thin. Also, the coal lays fiat in some
mines but dips rises very much in others. There
are faults and troubles; bad and soft coal in some
mines, but in others the coal is all good, and there 10
nothing to impede plans in operation. The dfsad-
vantages to contend with in some mines numer
GUS that good profitable mode of working out the
coal cannot be adopted.
do not think it right for any to condemn any
mode of working out COAL unless he knows well the
nature of the roof floor and coal, and all the circum
stances that arise in mines for the plan that is
condemned may be the best that be used for that
seam of coal, when all the conditions considered
know that there are many plans adopted by mine
bosses not having knowledge of the nature of
things and for this Institute be regarded
as school in their behalf, and also to members as
well, that may study and prepare ourselves to
adopt good plans of getting out COAL which would be
credit to mine bosses, and also make good
profit to our employers. The mine boss should have
such foresight to in his minds eye the proper
plan to adopt before he lays off his mine not, he
can not see his way clear before him; he would be
like person bewildered, who had lost his way in
forest.

am glad TO state that we have mines in this coun
try, one mode of getting out coal is what we term
'Long wall work. also another, ''Pillar room
working, also "Bank wide working; yet each and
all modes in the of working Iquote the fol-
lowing from Mr. Roy's writing in regard to pillar and
room working. 'Pillar and room working" as its
name indicates, consists in forming pillars and room
alternately. The proportion of coal mined away, TO
that left standing being governed by surrounding cir
cumstances and conditions. Rooms are made wide
and pillars narrow when the roofis hard and firm,
and the thickness of the everything strata is not great
When the roof is tender, and the superintendent mt
strata heavy narrow rooms and strong pillars
quired.
Long wall working has not been adopted in this
county, to knowledge neither has it in this State
to any extent. I think that behind the times
in not adopting the long wall system, wide work
ing, roof and floor both hard, and believe
that by adopting either that great saving could
be made in getting out COAL then all the coal could
be got out, and should the rooms Dip road can be
made from the level of the dip the next above
it, and by doing coal could be got out down grade
in place of grade is often the in the Coato
district Imean to adopt wide working as find good
results therefrom. A part of the works where am
mine boss is driven wide. think that five rooms of
twenty feet width, the average width of rooms
in this country, can be worked to advantage. This
would make one hundred and twenty-four feet of a
breast. Should it be too wide for five sixth
road could be put in it could take the width -
the waste pillars that leave in the mines un
touched.
Another great advantage see in adopting this plan
of the wide work. is that it would pay to shoot down
the roof of of the wide enough for road
that mule could in to get COAL in place of having
men to act as mules, as is now the case.
My paper, am aware, could be made more inter-
esting by explanations in regard to getting out
coal. The different modes adopted should by drawn
on paper, but circumstances at present prevent me
