The fire already referred to as having occurred in the Yellow Jacket, Ken- 

 tuck, and Crown Point mines is one of the most remarkable disasters in the 

 history of mining in this country. Although originating in the Yellow Jacket 

 the terrible effects were shared by the adjoining mines, and the loss of life 

 was much greater in the Crown Point than elsewhere, owing to the fact that 

 the draught of air passing down the Yellow Jacket shaft through the Ken- 

 tuck levels and up the Crown Point shaft, filled those mines and all their ave- 

 nues of escape with a dense volume of smoke which, instantly suffocated the 

 unfortunate men who were overtaken by it. The origin of the fire, although 

 not positively known, appears from the report of Mr. J. P. Jones, superintend- 

 ent of the Crown Point mine, to have been on the 800-foot level of the Yel- 

 low Jacket mine and near the south boundary line of that property ; and it is 

 believed to be probable that when the night men left the mine at 4 o'clock in 

 the morning, one of them thoughtlessly left a lighted candle sticking in a splin- 

 tered and resinous stick of timber, which, becoming ignited, communicated the 

 fire to the timbers adjoining. It is further supposed that the fire burned 

 slowly at first, creeping along the level toward a door dividing the Yellow 

 Jacket from the Kentuck, which door, being closed, checked the circulation 

 of air and caused a slow combustion ; but as soon as the door burned from its 

 hinges the smouldering mass of timber burst into flame, while the great vol- 

 ume of smoke and gas swept through the mines suddenly, overwhelming the
