heating the air it expands and light
ems and Iushes up the shaft and Of
course the heavy or cold air rushes
IN at the down cast to fill up the
space. A great many miners use
tans at the top OF the up cast shaft
which answers the same purpose 40
the furnace, this fan being run by
machinery. The condition of the
atmosphere has considerable to do
with the quality and quantity OF air
received IN the mines. When 1t 10
damp day the air is not SO pure,
being softer, the same as when the
wind is IN the south it is not as pure
as when It is IN the north The
temperature in the NINE IS variable
according to the depth under ground
and the number of men and mules
worked therein. There would be u
natural ventilation from these causes
but not enough to furnish air tor
man and beast. The air to have .
continuous circuit and reach all parts
| of the NINE must have channels leff
open, and men working IN various
parts Of the mine cannot he too care
tul in this respect in seeing that then
supply of air is not interferred with
by distractions placed in the way.
Any practical miner can readily tell
# he has sufficient air, or il the sup
pIv is pure from obnoxious gases,
this he can tell by his own feelings
or by holding his lamp in the draft.
DIVISION WORK.
have devoted much study and
observation as to the best methods
of furnishing fresh AIR to men at
work, and OF taking away the i'm
pure arr already breathed and the
smoke and impure gases. The
present system used in our MINES -
10 have only one draft OF air going
the tull length of the mines, every
miner in the works breathing the
same air, now my theory is, that the
men should be worked in divisions
and the impure AIR or that used by
each respected division separated
from the pure air by means OF an
over cast and taken off to its escapes.
This VIC believe, would prove more
satisfactory and healthiul to the men
and be of benefit to the company ir
as much as the men could do much
more work and IN more satisfacto-
rv manner under such favorable cir-
cumstances. This is ro wild theory
but is eminently practicable and
should be put into effect.
BOILER TESTS.
All boilers used to generate steam,
! tor the engines at the mines have
been tested by hydrostatic pressure
. and warm water, by qualified per-
. son every six months, and the papers
: filed IN my office.
| IRON AND COPPER TAMPING RARs.
AS a number who may read this
report might wonder what is meant
by tanning bar very short expia-
: nation we think would not be amisl
at this time. A tanp,ng bar o,
1 tamping iron as it is some times
: called, is a bar used to firmly embed
the tampting substance onto the
power, this bar has crese to fl
: around the needle so as to make the
. tamping matter thoroughly compact.
X In the tamping process accidents
q often happen by the bar striking fire
from sulphur which substance i
K found in greater or less quansitie'
S IN all coal. The question is OTTER
in dispute which is the safer to pre-
NJ vent accidents, the IRON or copPe
Is bar In a test case by scientI6'
z men OF Europe, cut OF 36 cases rest
" ed, 10 struck fire with iron and
&c with copper, so that the perccntse
AZ IS greatly in favor OF copper. How
m ever, a great many miners differ o
this question and we leave the mat
ter with the practical miner to us
n his own Judgment. Either Is sat
