mped to the surface through the material shaft. Thepumping was of necessity at times very slow on account of thenumerous falls which had taken place by the shifting of pumpsand by the resumption of mining before the pit was clear ofwater. On May 30, 1904, just one year after the beginning ofpumping operations, the mine was completely pumped outBesides the 516,000,000 gallons which filled the mine, the mine,was making about 500 gallons per minute during this period,!which amounted to approximately 276,000,000 gallons. Thetotal number of gallons pumped was therefore 792,000,000. The air compressors which kept these pumps in operationwere worked to their full capacity. To relieve them thepumps located around the lodgment at the shaft bottom weredriven by steam. The action of the gases from the fire on the pipes, ropesand iron work around and in the coal shaft was very destruc-tive. All the rope and pipe that had been exposed to it wereso badly eaten that complete renewals were necessary.

56 THE CANADIAN MINING REVIEW. I In the fire section of themine both xieeps on the Northside had fallen completely toa height in some places of 12and 15 feet, as shown by thecrossed shading in plan. Invery few places was it pos-sible to crawl over these falls.This necessitated much labourand expense in cleaning, tun-neling and timbering to placethe travelling road and haul-age way in a fit condition foroperation. Even if it had beenpossible to do without the useof these roads, the shale androof coal were found to giveoff a certain amount of heat,on the haulage road parti-cularly. For this reason itwas considered better to clearit out than to run the risk ofthe fire starting again on thisdeep. There was no apparentreason why the temperatureof this material should havebeen so much higher than atany other place to which therewas access unless the dust,which was very fine, com-bined with oil dropped fromthe pit tub axles, made thecondition more favorable forspontaneous combustion, andwith
