Essential Factors in the Formation of Producer Gas
From Introduction Scope and Purpose of Inquiry: "The Bureau of Mines, to which the testing and analyzing of fuels as carried on by the United States Geographical Survey has been transferred, is continuing producer-gas investigations at the testing station at Pittsburgh, Pa. Results of the gas-producer tests made at the coal-testing plant erected at St.Louis, Mo., and of a study of some of the problems that came up in the tests have been published by Geological Survey. Results of the tests made at Norfolk, Va., and Pittsburgh, Pa. and of further studies of particular problems, will be published by the Bureau of Mines."

Résumé of Producer-Gas Investigations: October 1, 1904-June 30, 1910
From Scope of Report: "The purpose of this report is, therefore, to present in convenient form all the more important data accumulated in the course of the tests described, in order that the results may be readily accessible both to the Government officials having charge of the design, purchase, or care of power plants and to all persons interested in the development of the internal-combustion engine and the gas producer as means for utilizing the energy of fuels."

Incidental Problems in Gas-Producer Tests
From Introduction: "In the course of this study many incidental problems of prime importance have demanded consideration. Among them is the determination, under practically constant conditions, of the duration of gas-producer tests necessary to reduce the possible error to minimum. A discussion of this proper length of test period forms the part of this bulletin."

Recent Development of the Producer-Gas Power Plant in the United States
From Introduction: "A summary of the tests made at St. Louis and a resume of the conclusions to be drawn from the tests and from the opinions of gas-producer manufacturers on the status of the gas producer and gas engine was published in a Survey bulletin in 1907. As it is desirable to repeat much of the material that appeared in the former bulletin (now out of print), this presentation may be regarded as a revision of the previous one, although considerable information not previously available for publication has been added."

City Smoke Ordinances and Smoke Abatement
From Introduction: "In connection with the fuel investigations conducted by the Bureau of Mines much information has been accumulated as to the smoke abatement activities in various cities. The essential features of the information are presented in this report, which, it is believed, will be of public interest and benefit, especially to those communities that are just beginning organized effort to abate unnecessary smoke."

Analyses of Coals in the United States with Descriptions of Mine and Field Samples Collected between July 1, 1904 and June 30, 1910 Part 2. Descriptions of Samples
From Introduction: "This volume contains the descriptions of the samples whose analyses are published in the preceding volume, Part I of this bulletin. The descriptions have been compiled from the notebooks of the persons who collected the samples, have been condensed from accounts given in published reports of the United States Geological Survey, or have furnished by the collection themselves. Inasmuch as the descriptions represent the work of many persons during a period of six years, and inasmuch as they were recorded under widely differing conditions, they necessarily vary in fullness detail."

The Volatile Matter of Coal
From Introduction Scope of Report: "This bulletin is a report on an investigation of the volatile matter in several typical coals-its composition and amount at different temperatures of volatilization. As the investigation is still in progress and will doubtless include other coals than those already examined, the bulletin may be considered a preliminary report, stating the problems studied, the methods used, and the results thus far obtained."
