<br />MINING & MINF. METRODS- Continued,
<br />to a negligible amount. Note. The above description was
<br />Furnished by Mr. Finlay, Manager.
<br />In some narrow veins, the mining is done without
<br />timbering, by letting the broken rock Pill the scopes, only
<br />enough being drawn out to leave room Por the miners to work in
<br />the backs, VPhen the atope is worked out, or up to the next. level,
<br />the ore is all drawn out, and stops abandoned. The above method
<br />implies good vein walla.
<br />TIMBERING.
<br />The square set syatem of timbering, (sawed lumber)
<br />is employed in all drlPts and stopes having a width greater than
<br />12 Ft., the atull syatem being employed in those of lean width.
<br />Condition of timbers, good, and in all places suPPioient, except
<br />those hereinaYter mentioned. The timbers are prepared in timber
<br />mill, being mostly red spruce and pine. The loading shoots employ-
<br />ed, are the ordinary lip shootq, with lattice, gates.
<br />TRAMMING.
<br />The underground tramming is done in steel Dare,
<br />26 x 42", 28" deep, capacity, 17-1~2 cubic Pt.: end dump. Trackage,
<br />12~ rails.
<br />DRAINAGE.
<br />At the present time, no pumping is being done,
<br />owing to the Pact that the water iS standing at a depth oP about
<br />1040 Ft „ and as plenty oP ore remains to be handled above that
<br />level, the expense of pumping has been abandoned Par the present.
<br />The pumping plant is distributed ae Follows;-
<br />A Snow, compound condensing pump, capacity 1000 gallons, at 800
<br />level No,l ehaFt.
<br />A Knowles, triple expansion pump, capacity 12000 gale. per minute,
<br />depth 1000 Ft., installed in station 20 x 64', at 900 level No.l
<br />shaft,
<br />Other pumps are located on the 1100 level under water, A 6 in,
<br />water column, comes up the seat winze to the 900, and out aroes-
<br />cut to large station pump, ehowing~ that pumping was done, through
<br />winze to 900 level,
