From introduction: "The purpose of the Bureau of Mines in publishing the results is to show the factors which may affect the accuracy of CO2 recorder and the manner in which a recorder should be tested."

From Preface: "The aim of this bulletin is to present to the marble workers of the United States a concise statement of the most efficient and economical methods now in use for producing and preparing marble. The observations outlined refer chiefly to the methods employed in the quarrying of marble and the conditions that affect successful operation; the structure of marble and its relation to quarry processes; waste through rock imperfections and inefficient quarry methods; and means of eliminating such waste or utilizing it if elimination is impossible."

From Introduction: "This report presents the results of one phase of this study and shows how atmospheric air, after entering a coal mine, loses oxygen and gains carbon dioxide with resulting formation of so-called black damp."

From Introduction: "This report treats of method of preventing some of the waste of the natural gas incidental to oil mining. This method, the condensation of gasoline from natural gas, offers to the oil operator and others a profitable means of utilizing some of the oil-well gas now being wasted."

From Introduction: "The present paper is a report of a detailed study of the bituminous dusts of Illinois mines, and is a part of the investigations conducted by the bureau in cooperation with the Illinois State Geological Survey and the department of mining engineering of the University of Illinois."

Report published by the U.S. Bureau of Mines which is a compilation of fatal accidents in coal mines located in the United States along with notes and data about the number and causes of the fatalities. The statistics are organized according to the calendar year and divided by location to improve analysis.

Report issued by the U.S. Bureau of Mines covering accidents that happened in metal mines located in the Untied States including statistics for injuries, fatalities, kinds and causes of accidents, and operational data, such as number of mine workers and shifts worked. This report includes tables and illustrations.

Technical paper issued by the Bureau of Mines over the quarry accidents during the year of 1915 in the U.S. The locations and types of quarry accidents are presented. This paper includes tables.

From Introduction: "During the early years of these plants little success was anticipated from the use of bituminous coals and lignites, but in 1904 and 1905 it was fully demonstrated at Government testing station at St. Louis that these fuels could be utilized to excellent advantage. However, although many producer-gas plants in daily operation are still skeptical regarding the successful commercial use of these fuels."

Report concerning the loss of aluminum experienced during the melting process. This report shows the magnitude of the loss through various experiments. Index begins on page 85.

From Introduction: "The object of this report is to give briefly information of present value relating to the manufacture and uses of the various commercial alloy steels, with the hope of stimulating the demand for such steels and extending their practical use."

From Preface: "The following paper on miner's nystagmus in the United States, Mr. Hoffman has reviewed the results of investigations in Europe and has drawn some tentative conclusions as to the possible frequency of the disease in this country. Whatever may be the prevalence of nystagmus in the United States, its seriousness as a disease and the need of national and State agencies cooperating in endeavors to obtain exact information regarding it are deemed sufficient reasons for the publication of Mr. Hoffman's interesting and suggestive paper.

From Scope and Purpose of Investigation: "The direct purpose of the bulletin is, on the one hand, to prove to possible consumers of molybdenum that the element is not as rare as commonly supposed, and that this country possesses many deposits of low-grade ore from which large supplies may be derived, and on the other hand, to prove to present and prospective producers of molybdenum that there is a latent market for their product in the alloy-steel trade, which needs only the assurance of steady supplies for a considerable development."

From Introduction: "Although the purpose of this paper is to describe gold dredging in Montana, a brief mention of some early appliances used in New Zealand, Australia, and California may serve as a world-connecting link in our consideration of the development of gold dredging."

From Introduction: "In this report considerable space has been devoted to general and theoretical principles on the ground that under modern conditions the best results in any field of activity can be attained only with the aid of an adequate knowledge of the best theories underlying the practice. The diffusion of such knowledge in the field of sampling metallic metallurgical materials appears to have been quite insufficient, and it is felt that when the principles involved are once thoroughly comprehended their universal application will be appreciated, so it will make no difference whether pig iron of gold bullion is offered for test. "

From Introduction: "Technical Paper 66 deals with the mud-laden fluid process in general and No. 68 with its application in Oklahoma. Rather than reprint these publications, it has been considered advisable to replace them with the present report, which includes the results of more recent investigations. The methods of using mud-laden fluid are an outgrowth of the rotary drilling system, which was developed in Texas and later employed in Louisiana and California."

Report discussing techniques for the mining of large masses of low-grade ores such as though found in Santa Rita, NM. It is hoped that a study of the methods used at Santa Rita will help engineers in other industries who may have to handle large masses of material.

From Introduction: "The purpose of this paper is to describe briefly the general character and commercial quality of some of the coals mined in the United States that reach tidewater shipping ports, and to show in a general way the important characteristics of those coals that by reason of transportation facilities and the situation of the coal fields are most available for export."

Technical paper issued by the Bureau of Mines over the underground wastes of oil and gas in drilling fields. As stated in the introduction, "the writers have endeavored to establish the manner and importance of underground waste by citing a few cases and to show the means whereby it can be prevented" (p. 5). This paper includes illustrations.

From Introduction: "This bulletin presents a summary of available information regarding the sources of uranium, radium, and vanadium, the methods used in treating the ores, and the uses of the the finished products. In particular the paper describes the ores found in the United States, giving especial attention to those characteristics of the ores and the conditions of their occurrence that affect mining and treatment."

From Introduction: "This bulletin is a compilation of the results if coal analyses by the Government, including those made in the fiscal years 1908-1910, which have been previously published, and later analyses representing coals analyzed during the fiscal years 1911-1915."

From Introduction: "This bulletin is a revision of Bulletin 63 and is published by the Bureau of Mines in order that purchasers of coal for Government, State, municipal, or private use may be informed regarded advances or refinements in sampling coal deliveries and preparing specifications for the purchase of coal."

Report discussing results from analysis distillation of petroleum.

From Preface: "This bulletin deals with the cracking of petroleum and other hydrocarbons and the production thereby of gasoline, benzene, and toluene."
