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.

"Muscadine grapes are indigenous to the southeastern section of the United States, where they grow in greater or less profusion in the wild state. Through careful selection from the wild grapes and scientific breeding there have been developed a considerable number of varieties particularly adapted to the home needs in the Southeast, both as table grapes and as raw material for a variety of food and beverage products. Not being resistant to low winter temperatures they do not thrive in the northern grape districts. Muscadines are relatively resistant to grape diseases and insect pests and do well with a minimum of care, but, like most fruits, respond favorably to good cultural treatment. This bulletin sets forth in nontechnical form the information accumulated by the Department [of Agriculture] over a considerable period of years on muscadine grape varieties, their bleeding, culture, and uses." -- p. ii

This bulletin describes terracing methods that are able to combat soil erosion and conserve water. There are three types of terraces (drainage, absorptive, and bench) and plans, specifications, construction practices are provided in the bulletin.

This bulletin tools and methods of tilling which can help reduce or control soil blowing and soil erosion on farms in the northern Great Plains of the United States. Among the crops discussed with relation to tilling methods are beans, corn, sorghum, potatoes, alfalfa, and sweet clover.

"The farmer can buy lime from commercial sources in the form and degree of purity desired; he can produce his own if he has a convenient supply of raw material; or he can cooperate with his neighbors in working a deposit. This bulletin deals with factors which should be considered by a farmer or a group of farmers before investing in equipment for obtaining lime from limestone or marl." -- p. 1

This bulletin discusses the culture of the field and diseases and insects which commonly afflict it. Diseases discussed include leaf spot, stem blight, bacterial blight, left blotch, powdery mildew, downy mildew, anthracnose, fusarium wilt, root rot, and mosaic. The pea weevil, aphid, and moth are the insects discussed, as well as the nematode.

"This bulletin describes farming practices that conserve soil, and how such practices may be applied to farms in a large part of the South. Its scope is limited to that part of the Cotton Belt extending west from the Georgia-Alabama line to central Texas and southern Oklahoma." -- p. i.

This bulletin discusses methods of soil conservation in the northeastern United States that can prevent erosion. Soil conservation practices vary with the type of agriculture being used. In addition to general farming, conservation for dairying, orcharding, market gardening, and single-crop farming are discussed.

"From the producer's standpoint, the correct grading of turkeys is a very important factor in the success of his enterprise. Without dependable grading, successful marketing is practically impossible, and without successful marketing, little profit may be expected. Whether the producer grades his own turkeys or has this done by a licensed grader, a familiarity with the grade descriptions and how the grades are applied will create a mutual understanding and be a source of satisfaction to producers, graders, and buyers. How to grade according to Government standards can be learned by any producer who makes a thorough study of the grade factors involved. This bulletin attempts to point out by description and illustration the most important of these factors." -- p. ii

Infectious anemia (which is also known as swamp fever) is a disease which afflicts horses and mules and results in significant financial losses for farms every year. This bulletin discusses the causes and forms of the disease, the accompanying anatomical changes in infected animals, the diagnostic process, and control measures which can be taken to prevent further spread of this serious illness.

Revised edition. "This bulletin aims to furnish, in concise form, information that will be of practical help to the amateur fruit grower. It deals with the widely grown temperate-climate fruits, such as the apple, pear, peach, plum, cherry, grape, and berries. Lists are given of varieties desirable for the different parts of the country. Because of the number of fruits considered and the territory covered, cultural directions are necessarily brief, but they cover the most important general points." -- p. 2
