From Introduction: "This bulletin, which is arranged in three parts, treats of the causes and prevention of blast-furnace breakouts, explosions, and slips."

Report presents a preliminary study of the state of the art of the design of carburetors for gasoline engines used in aeronautic, marine and land transportation service.

From Scope of Report: "The first part of this report outlines the present factors in the problem of coking Illinois coals and points out the future prospects. The second part of this report deals with the character of Illinois coals, their nature, physical properties, and chemical composition. The last part describes the tests made and gives detailed results."

From Purpose and scope of Investigations: "The combustion investigations of bureau are carried on in two parts. One part is the study of the process of combustion in the fuel bed as affected by the rate of supplying air through the fuel bed, by the character of the fuel as regards structure and composition, by the thickness of fuel bed, by the method of feeding the coal and the air and by the method of heating the coal. The second part of the investigation is the study of the process of combustion of the gases and other combustible rising from the fuel bed in the combustion space, after a sufficient quantity of air has been added. The results of the study are given in this report."

From Introduction: "The results of concentration experiments with these ores made a more thorough and systematic investigation desirable. In consequence, the author subsequently collected samples in the district, and these became the basis of the experimental work described in this report. The results are published by the Bureau of Mines as a part of its efforts to increase efficiency in the utilization of mineral resources."
