Excerpt from Notes on the Use of Low-Grade Fuel in Europe In its investigations of fuels belonging to or intended for the United States, which form a part of the general work it is doing to increase efficiency in the utilization of the mineral resources of the country, the Bureau of Mines has given attention to the combustion of fuel in furnaces. And gas producers and has tested a large number of samples of coal and lignite to determine their value for producing power. Economic conditions and the realization of the value of scientific research have caused European countries to study their natural resources closely in order to determine how these resources can be utilized most efficiently. The wide distribution of fuel resources in the United States, the abundant supply of high-grade fuel, the relative freedom from large areas of congested population, with their excessive industrial demands, and a careless indifference to efficient utilization, due in great measure to the abundance of our resources, have led us to neglect far too long the serious consideration of problems upon which hinge many of the possible activities of future generations. The unrestricted use of our better grade fuels and the ruthless waste and neglect of fuels that should be of real commercial value are phases of our national extrava gance that are little short of appalling. The Bureau of Mines has repeatedly called attention to the rate at which the supplies of high grade fuel are being depleted and the need of investigations to asoer tain how waste in their mining and utilization can be lessened or prevented.
