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."

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."

Comparative Tests of Run-of-Mine and Briquetted Coal on the Torpedo Boat Biddle

From Introduction: "With the particular equipment used in the tests both coal and briquets were far from smokeless; consequently the data of this bulletin are applicable only by analogy to parallel operation with a coal more nearly smokeless, but nevertheless applicable with much reliability. It was the original intention to make a set of preliminary steaming tests alongside a dock (which tests furnish material for this bulletin) an to finish with a set of running tests at sea; but the running tests were never made. for lack of time and men."

Tests of Run-of-Mine and Briquetted Coal in a Locomotive Boiler

From Object of Tests: "The primary object of the tests was to study the relative performances of the two types of briquets and of the coal, with reference to efficiency, tendency to smoke, and the ease with which steam could be kept up, when each of the three varieties of fuel was burned at several rates of combustion. Many secondary objects were in mind, the data concerning which are discussed under "Effect of varying rates of combustion," pages 20-27."

Comparative Fuel Values of Gasoline and Denatured Alcohol in Internal-Combustion Engines

From Introduction: "Under the terms of the act establishing the Bureau of Mines, this bureau was authorized to carry on the work of testing and analyzing fuels which had been conducted by the technologic branch of the United States Geological Survey. Therefore, the first investigations of the liquid mineral fuels logically embraced a careful series of comparative tests of gasoline and denatured alcohol in engines. The report is published by the Bureau of Mines because of the transfer of the fuel-testing investigations to this bureau."

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."

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 Wheat Jointworm and Its Control (open access)

The Wheat Jointworm and Its Control

Revised edition. "The wheat jointworm is a very small grub which lives in stems of wheat, sucking the juices of the plant and causing a swelling in the stem. The egg from which it hatches is laid in the stem by an insect resembling a small black ant with wings. This insect attacks no other kind of plant. The injury which it does to wheat is very distinct from that caused by the Hessian fly, yet the depredations of these two insects are often confused by farmers. This paper is intended, therefore, to give a brief outline of the life history and the nature of the injury to the plant by the jointworm so that any farmer may readily recognize its work and be able to apply the measures of control herein recommended." -- p. 3-4

"Within recent years an increasing number of reports of serious damage to the corn crop by a robust black beetle have been received from most of the Southern States. A noteworthy outbreak occurred during the early summer of 1914 in the tidewater section of Virginia. As very little was known regarding the natural history of this pest, this bulletin has been designed to supply this information. By following the control measures recommended herein it is hoped that the ravages of this pest may be largely overcome in the future." -- p. 3

Muscadine Grapes

Revised edition. "Muscadine grapes, which are native to the southeastern part of the United States, thrive in most soils of that region. They can be grown successfully in the Southeastern States, where American bunch grapes do not thrive. furthermore, they are suitable for home gardens as well as for commercial use. In fact they are perhaps the most satisfactory of all fruits for the home garden in this region. They cannot be grown, hoever, where temperatures as low as 0 °F occur habitually and may be injured at somewhat higher temperatures. Muscadine grapes are relatively uninjured by diseases and insects and produce well with a minimum of care, but they resopnd favorably to the good cultural practices recommended in this bulletin. The varieties described or listed produce fruit suitable for making unfermented juice, wine, jelly, and other culinary products and for eating fresh over a long season." -- p. ii
