MINE FIRE 1(6 underground is attended with more care than in any otherdistrict in Illinois. In almost every mine examined in thisdistrict the provisions of the State law with respect to thetransportation of hay to underground stables are scrupulous-ly observed. The hay, which is baled, is carried in a speciallyconstructed car. Fig. 54 shows a steel hay car in an under-

At a great majority of the mines in Illinois mules arestabled underground, but at many mines the mules are stabledon the surface. At one mine having 24 mules on the second-ary haulage they are hoisted out each night. It requiresthirty minutes to hoist and the same time to lower them andthe total expense of these operations is $0.000888 per ton ofcoal hoisted. 174 COAL MINING INVESTIGATIONS In many mines an unnecessary liability of fire is addedby allowing comparatively large quantities of lubricating oilto be stored in the run-around or at other points near theshaft. In one mine two full barrels of oil and four emptieswere kept within 25 feet of the main hoisting shaft, while 200feet away were stored two full and three empty barrels. Inthe newer mines danger of underground fire is reduced to
