Reports of the Inspectors of Mines of the anthracite and bituminous coal regions of Pennsylvania, for the year 1893. t of this colliery and at a point in thisshaft, 460 feet from the top of it, and 510 feet above the bottom, tworock tunnels have been driven on the North side of the shaft towardthe Mammoth vein, forming the bottom and turnout of the new footof the shaft and joining each other before reaching the vein; the onebeing driven around the shaft having a small plane and from it adescending grade to cari-y the empty cars to the junction with theother tunnel, which is driven with an up grade from the shaft infavor of drainage and easy movement of loaded cars. Tlielengths of these tunnels at present are 375 feet and 710 feet respect-ively ; they will open up two lifts of Mammoth vein coal on an averagepitch of 45 degrees, which has proved to be about fifty (50) feetin thickness and in good condition, and will make this a very product-ive colliery.
