Technical paper issued by the Bureau of Mines over studies of waste in oil and gas fields in the mid-continent area. As stated in the introduction, this report "describes the general amounts and kinds of waste, and attempts to show the importance of conserving these natural resources" (p. 5). This paper includes tables, maps, illustrations, and photographs.

Report discussing an international conference on mine-experiment stations assembling in Pittsburgh, Pennsylvania. The United States sent invitations to countries that had mine-experiment stations, Great Britain and Canada were the only countries, that did not accept invitation.

From Introduction: "The investigative work described in this report was undertaken by the Bureau of Mines under a cooperative agreement with the department of mining engineering of the University of Illinois and the Illinois and Illinois State Geological Survey. The purpose of this agreement was to provide for a comprehensive investigation of coal-mining conditions in the State, with especial reference to the possibility of lessening waste in the mining and preparation of coal and of reducing the dangers to which miners are exposed. Thus, it studied the occurrence of gas (methane) in the mines of the southern part of the State, tested the inflammability of the coal dust from many mines, examined the efficiency of the control of ventilating currents, and investigated the factors affecting the humidity of mine air with respect to their bearing on the occurrence of mine explosions."

Bulletin issued by the U.S. Bureau of Mines: "This publication is devoted exclusively to a review and abstracts of decisions based on the laws governing the rights and duties of mine owners, operators, miners, and persons trafficking in all kinds of mining properties. It includes abstracts of current decisions of all the Federal and State courts of last resort on questions relating to the mining industries" (Bulletin 61, p. 9).
