From Introduction: "The investigation described in this bulletin was undertaken by the Bureau of Mines in an endeavor to obtain exact information on some of the basal questions involved in the use of gasoline locomotives in mines, this investigation being one of many that the bureau has been conducting in its efforts to increase safety and efficiency in mining."

Technical paper issued by the Bureau of Mines over studies of analyses of coals. The results are discussed and presented on various diagrams. This paper includes tables, and illustrations.

From Introduction: "This bulletin is published by the bureau primarily for persons who seek information on the subject of metal-lurgical smoke but are unacquainted with the technical language of metallurgy. The effort is made in this paper to present the problem of metallurgical smoke as it actually exists, without bias of any kind."

Technical paper issued by the Bureau of Mines over safety prevention in coal mines. Preventing mine explosions is emphasized. Methods used in mine safety are discussed. This paper includes tables, illustrations, and photographs.

Purpose of Report: "In this report an attempt is made to discuss the first cost of each of several types of mine-ventilation stoppings, as well as the total annual expenses of maintaining a stopping during its required period of service."

Technical paper issued by the Bureau of Mines over studies of low-grade fuel use in Europe. The results of the studies are presented and discussed. This paper includes tables, and illustrations.

From Introduction: "This report presents the results of an investigation begun by the Government in the summer of 1907, the investigation being started under the immediate supervision of Dr. J. A Holmes and continued under him as director after it was transferred to the Bureau of Mines in 1910, the field studies being completed in the spring of 1912. The purpose of the investigation was to obtain information on the origin of the inflammable gases in coal and the conditions under which they occur."

A report to the Weather Bureau, Washington DC, from the chairman of the Subcommittee on the Atmosphere in Relation to Aeronautics describing the activities accomplished and the proposal of work to be undertaken by the subcommittee.

From introduction: "This bulletin aims to give the metal miner and the quarryman information similar to that given the coal miner in Bulletin 17. Inflammable gas or dust is seldom, if ever, found in quarries or metal mines, and the danger from using explosives there is less than in coal mines; but, as the figures show, the number of men killed and injured yearly in accidents caused by explosives proves the need of both miners and mine officials striving to see that none but proper explosives are used and these are used properly."

This report documents the examination for oil in the vicinity of Quanah, Hardeman County Texas during the fall of 1914.

This document reports the presence of oil and gas in Palo Pinto County, Texas, as studied by the United States Geological Survey in the fall of 1914.

Report presents an equation that connects all the major qualities of a fabric, from which the fabric may be rigidly designed with respect to maximum ultimate economy.

From Preface: "This bulletin presents the report of the commission and the papers, prepared by the various experts, which give the results of investigations undertaken by the commission and form the basis of its findings."

Part 1 presents the results of a wind tunnel test of a biplane model with an 18 inch span. The lift, drift, and pitching moment were measured for a series of angles of incidence corresponding to the maximum possible changes of flight attitude. Only the discussion of symmetrical or longitudinal changes is given. From the observed rate of variation of the forces and pitching moment, it was possible to calculate the derivatives needed in the complete theory of longitudinal stability in still air.

Discusses habits; economic status; characteristics and development of young; pelages and molts; and geographic, individual, sexual, and age variation. Describes subfamilies, history, and generic names of the family Talpidae. Describes, lists locations, and provides a key for genera, species and subspecies.
