ndle the timbering and clear away the fallen Hill. Long WALL Mining and Emery Pit—Burland 655 The coal after being kirved or mined, which by-the-wayis often almost omitted, should be nicked. The writer has noteda man firing four shots without detaching as much material as agood miner would fall in one shot. In the Emery, this is done atthe head of the gates and the coal shot down to the right and left. Haulage. The underground transportation is effected by horses andmechanical devices. Small Xe\\foundland ponies draw the carsfrom the face to the main coupling sidings or directly to the pitbottom. A special feature worth noting is the Lower North levelwhere a tail rope system is employed to pull its trip to a spare roador flat past Xo. 5 gate. Two pull wheels are situated at thisgate and another auxiliary rope may be attached to the head ofthe trip and the cars taken to a flat near the working face. Horsesdraw to the upper spare roads and exchange full tubs for the in-coming empties.

Plate 12 Plate IJ illustrates an ingenious device for disconnectingthe head rope on the outbound trip. The tuba gain Hufficientmomentum from the grade to allow them to run past the doublednim donkey and out to the main coupling station of the deeps. 656 Long WALL Mining and Emery Pit—Burland The rope acting as a tail rope on the inbound trip is passed underthe roller and when the roller passes over the socket, out bye, theclutch is thrown as indicated by the dotted sketch. The main haulage rope is driven by a Corliss Engine, whichalso operates the French slope rope. This engine has a 20 x 60cylinders and runs at 60 revolutions per minute. The rope passesdown a bore hole lined with piping to head of deeps. Anothercounter-balance takes care of the slack underground and issituated down the deeps. Tubs are coupled to rope by a methoddescribed in the paper of E. P. Cowles to Canadian Mining Institute(1909 competition), so the method will not be touched on in thisdiscussion. The mine cars
