This technical memorandum constitutes a complete report on a model study of the Pryors Island reach of the Ohio River, made for the purpose of determining the most effective plan of regulating works for the further improvement and stabilization of the navigable channel.

This memorandum, constitutes a report on the results of experiments conducted at the U. S. Waterways Experiment Station on a small scale model of that reach of the Mississippi River near and including Dogtooth Bend (Mile 32.7 above to Mile 4.0 below Cairo).

This memorandum constitutes a final report of the study performed at the U. S. Waterways Experiment Station on a model of the outlet works for the Wappapello Dam The model was built undistorted to the linear scale ratio, model-to-prototype, of 1 to 25. The general purpose of the model study was to check the hydraulic characteristics of all elements in the design of the outlet works, and to develop means of correcting any uneconomic, unsafe, or undesirable conditions.

From abstract: The Chitina Valley and adjoining area form part of a rugged alpine region in the southeast corner of the main body of Alaska and include a portion of the Chugach Mountains and most of the southern half of the Wrangell Mountains, to the north. The Chitina River is an eastern branch of the Copper River and rises in ice fields and valley glaciers occupying most of the country near the international boundary north of Mount St. Elias. The adjoining area described in this report includes the Hanagita and Bremner River district and the westward continuation of the north side of the Chugach Mountains as far as Valdez Arm and Klutina Lake. In addition, the geology of the upper White River district is described because of its relation to that of the Chitina Valley.

From abstract: The Quinton-Scipio district includes about 450 square miles, mostly in Pittsburg County but partly in Haskell and Latimer Counties, Okla. The stratified rocks exposed at the surface in the district are the McAlester, Savanna, Boggy, Thurman, Stuart, and Senora formations, of Pennsylvanian age, and consist of alternating beds of shale and sandstone with some coal beds and a few beds of limestone less than 1 foot thick. The total thickness of these formations exposed in the district is between 3,000 and 3,300 feet. There are probably unconformities at the base of the Savanna sandstone and at the base of the Thurman sandstone. Overlying the Pennsylvanian formations in parts of the district are unconsolidated sand, gravel, and clay, which in part belong to the Gerty sand, a deposit in an abandoned Quaternary (?) river channel. Other unconsolidated deposits include sand on stream terraces and Recent alluvium.

From introduction: Since the discovery of the Wayne-Dundee gas field in 1930 and the more recent discovery of large quantities of gas in the Oriskany sandstone about 2 miles north of the village of Greenwood the search for similar favorable structural features has been greatly stimulated in the Finger Lakes region and southwestward to the Pennsylvania line. To aid those interested in the area to gain a clearer understanding of the regional structure and its relation to the subsurface structure, parties in charge of the senior author were assigned during the field seasons of 1934 and 1935 to make a geologic study of Steuben County and parts of the adjacent counties.

This report is part of a series describing the structural features, the character of the oil- and gas-producing beds, and the localities where additional oil and gas may be found in parts of Osage County, Oklahoma. This part discusses the geology and resources in the southeastern part of the county.

From abstract: The San Juan country includes an area of about 3,800 square miles east of the Colorado River in San Juan County, southeastern Utah. This paper is based on reconnaissance geographic and geologic surveys made in 1910, 1915, 1925, and 1927-29.

From introduction: "In this paper are assembled and summarized many subjects relating to the copper industry in North America. Production of mines and districts, history of the industry in North America. Production of mines and districts, history of the industry, geology, of the principal deposits, and mining methods and costs are discussed."

From Introduction: "The present paper discusses regional resources, chiefly of gold, the existence of which has long been demonstrated by substantial production but which are so nearly marginal in value that their mining has been protracted and will probably continue indefinitely for many decades."

Report published by the U.S. Bureau of Mines which is a compilation of accidents in quarries located in the United States with data regarding the number and kinds of accidents as well as information about the mining operations (e.g., number of men employed, kinds of quarries, amount of work performed, etc.).

From Scope of Report: "In connection with the study of the oil-shale resources of the United States, the Bureau of Mines has carried on not only extensive laboratory and field investigations but has constructed and operated an experimental shale-oil plant in Colorado. This report is based entirely upon subject matter that appeared in published and unpublished manuscripts of the Bureau of Mines."

Report compiled by the U.S. Bureau of Mines including statistics on fatal and non-fatal accidents in coal mines located in the United States as well as data regarding the various operations (e.g., number of miners employed and average production). The information is organized into tables for comparison and the text draws some overall conclusions in the summary.

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

From Introduction: "The composition and carbonizing properties of 33 coals previously tested have been given in technical papers of the Bureau of Mines and in short reports published for the most part in the Proceedings of the American Gas Association. A complete list of publications on the work previous to 1937 is appended to this report. The present report gives the composition and carbonizing properties of seven additional coals from West Virginia. The data include results of blending test in which Beckley bed low-volatile coal was used with all the high-volatile coals except the Alma coal, with which Pocahontas No. 4 coal was used."
