Report discussing coal problems existing in Alaska, which Alaskan coal has high value.

From Introduction: "It is the purpose of this paper to describe some apparatus and methods which have proved satisfactory to those engaged in the chemical work of the investigations mentioned. While these methods and apparatus have been designed more particularly with regard to analysis of furnace gases, their use is by no means limited to that purpose."

From Introduction: "The problem is always to produce at a profit a briquet of satisfactory grade for the use intended. This problem will be made clearer by a brief summary of the available binders, followed by a preliminary discussion of the characteristics of a good briquet."

From Briquetting Tests: "The briquetting work undertaken at Norfolk had these specific objects: 1. To determine what percent of pitch or other binder was necessary to make a satisfactory briquet out of the coals tested. 2. To investigate the relative merits of different binders. 3. To provide briquets for comparative combustion tests of run-of-mine coal and the same coal briquetted."

From Introduction General Statement: "The investigations were so directed as to permit the testing of coals from different parts of the united States. The results show that certain coals from which good yields of gas had been expected can not be considered as available for illuminating-gas manufacture, whereas other coals give promise and should investigated further. The data contained in this report are the outcome of the cooperative work at the laboratory mentioned during parts of the years 1908 and 1909."

From Introduction: "The following report is a summary of the commercial results which were obtained from 2,000 tests conducted by technologic branch of the United States Geological Survey at St. Louis, Mo., and Norfolk, Va., in 1907 and 1908, under the technical supervision of R.H. Fernald, engineer in charge of the producer-gas section."

From Introduction: "For purpose of procuring data that could be using in estimating the value of the briquetting process as applied to American fuels, the United States Geological Survey, in cooperation with other interests, began in 1904, at the Louisiana Purchase Exposition, certain experiments involving the production and use of bituminous-coal briquets."

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."

Report issued by the Bureau of Standards over studies conducted on coupled circuits. Emphasis was placed on the secondary circuit and its inductance and capacity. The results of the studies are presented and discussed. This report includes illustrations.

Report issued by the Bureau of Standards over studies on instrument transformers. As stated in the first paragraph, "the principle of the method here described is the same for both current and potential transformers, being an application of the potentiometer method" (p. 281). The methods and equipment studied are presented and discussed.

From Introduction: "This paper is the result of a comparative study of ultimate coal analyses made and published by the United States Geological Survey. The initial comparisons, made from a relatively small number of analyses, not only confirmed a previous conviction that the elimination of oxygen incident to the development of a coal is economically far more important than has been generally suspected, but also showed that oxygen is very nearly as harmful as ash in coal."

Report issued by the Bureau of Standards over the conductivity of copper. Samples of commercial copper were studied, and the results are presented and discussed. This report includes tables, illustrations, and photographs.
