Book Description
Excerpt from Weathering of Coal For many reasons, present conditions often necessitate the storing of large quantities of coal. On account of the seasonable demand for fuel for'domestic purposes, mining interests find it to their advantage to store coal during the otherwise dull season and.thus maintain a uniformity in working conditions at the mines, which is in accordance with the principles of economic production, as well as prevent poor conditions and dissatisfaction among the miners. This fluctuatihgidemand'lihewise affects the coal dealer Who must have a supply of coal'on hand to supply the market. Manufacturers are beginning to see the need of supplying themselves with fuel in case their'supply be cut off by some unforeseen condition at the mines or in transportation companies. The Railway interests who? According to the Interstate Commerce Commission, used over one-fourth of the coal supply of the United States in 1905t'look out for their own coal supply even at the expense of other industries and are thus constantly prepared to continue their business should any contingency at the mines result in a temporary cutting off of their coal supply.
