Report on investigations into the construction of a lock in the Arkansas River including results of model tests and recommendations.

From Introduction: "The first demonstration plant sponsored by the Office of Saline Water was located in Freeport, Texas, and came 'on stream" in 1961. The incoming sea water was deaerated since both Speller (6) and Uhlig (7) recognized that dissolved oxygen was usually the controlling factor in the corrosion of iron stream condensate at temperatures even as high 400 degrees F. The water was acidified prior to daeration with H2SO4 to decompose the carbonates which subsequently would cause scale when the water was heated. After the carbonates were removed, the pH was raised to the neutral point, again to provide a less corrosive environment."

From introduction: Much of the ground surface around Mount Rainier volcano is directly underlain by loose geologic deposits that veneer the hard rock formations. Examples of these deposits are sand and gravel bars along the rivers, ridges of loose rock debris beside the glaciers, and sloping aprons of rock fragments beneath almost every cliff. Even though they are generally thin and inconspicuous when compared with the rock formations, these surficial deposits are clues to geologic events that. have profoundly influenced the shape of the park's landscape. Thus, from the character and extent of glacial deposits one can judge the age and size of former glaciers that carved the cirques and deep canyons of the park; from the mudflows which streamed down nearly every valley one can infer the age and size of huge landslides of the past that helped determine Mount Rainier's present shape; and from the pumice deposits some of the volcano's recent eruptive activity can be reconstructed.

Report issued by the U.S. Bureau of Mines discussing regional and state supply and demand data. As stated in the introduction, "data for 1960 and 1965 have been presented in tabular form as supply-demand balances, showing the development of the total supply available for consumption and the disposition of that supply-demand by consuming sector for each state and region" (p. 2-3). This report includes maps, tables, and illustrations.

Report issued by the U.S. Bureau of Mines discussing state and regional supply and demand data. As stated in the introduction, "the primary purpose of this study is to provide, on a state-by-state basis, petroleum and natural gas liquids industry data that can be (1) integrated into state and regional energy balances by source, form, and consumer sectors, and (2) used to determine interstate and inter-regional energy flows" (p. 1). This report includes maps, tables, and illustrations.

From introduction: The ruins of the pueblos and missions of Pecos lie on the east bank of Glorieta Creek near its junction with the Pecos River at the south end of the Sangre de Cristo Mountains in north-central New Mexico. Here the Pecos River and Glorieta Creek have formed a broad rolling valley in which the red adobe walls of the mission church stand as a striking monument to a historic past.

The phase shifts for proton-proton scattering as calculated from the one-pion exchange contribution (OPEC) alone are of some interest because they describe the scattering correctly in the high angular momentum states, and because in the lower angular momentum states the deviation from the OPEC phases is an indication of the strength of the two-pion and higher exchanges processes. The attached table gives the proton-proton nuclear-bar phase shifts as calculated from OPEC. Phase shifts and mixing parameters are given in degrees, as function of the T, the laboratory kinetic energy of the incoming protons in Mev. Phase shift and mixing parameters are listed in the angular momentum states.

Report issued by the U.S. Bureau of Mines discussing coal mining production and waste disposal. As stated in the introduction, this circular discusses anthracite refuse disposal (removal and utilization) practices and their effectiveness. Attention is also directed toward the rate of growth of the material, costs of disposal, and problems involving ownership of the refuse" (p. 2). This report includes maps, tables, illustrations, and photographs.

The following report describes the design and intended function of the tolerance comparator device, a tool designed to aid those engaged in the manufacture and inspection of parts as defined by drawings using positional tolerances.

The following progress report describes the examination of elements removed in comparison to a previous study on the power facility reactor operations.

Abstract: "Recent request for new sites has prompted an overall review of the Pahute Mesa area. The criteria used in this review are that the geology must be favorable and that horizontal spacing of emplacement holes being developed should be 2.5 to 3 times hole depth. The review shows that current emplacement requirements have exhausted available explored sites and have effectively eliminated 90 percent of the blocks of ground geologically favorable for chambered sites."

Overview of the mammals of Maryland, including descriptions of the orders and maps depicting distribution of the mammals.

Abstract: In the Blue Ridge Province of northern Virginia, Maryland, and southern Pennsylvania, Lower Cambrian beds are underlain by a thick sequence of greenstone and interbedded sedimentary rocks known as the Catoctin Formation. An area near Luray, Va., was studied to determine the thickness of the formation, its relationship to overlying and underlying rocks, and the original nature of the lavas from which the Catoctin greenstone was derived. There the Catoctin Formation lies unconformably on granitic rocks. Its basal sedimentary layer ranges from a few inches to 150 feet in thickness and contains pebbles of underlying basement rocks. The erosion surface beneath the Catoctin is irregular, and in several places, hills as much as 1,000 feet high were buried beneath the Catoctin lavas. No important time break is indicated between the deposition of the Catoctin Formation and the overlying Cambrian sediments. The original Catoctin lavas were basaltic and were probably normal plateau basalts. Columnar joints, amygdules, sedimentary dikes, flow breccias, low-dipping primary joints, and other primary structures are well preserved.

From abstract: Small deposits of native gold are present along an anastomosing system of quartz veins and shear zones just east of Great Falls, Montgomery County, Md. The deposits were discovered in 1861 and were worked sporadically until 1951, yielding more than 5,000 ounces of gold. The vein system and the principal veins within it strike a few degrees west of north, at an appreciable angle to foliation and fold axial planes in enclosing rocks of the Wissahickon Formation of late Precambrian (?) age. The veins cut granitic rocks of Devonian or pre-Devonian age and may be as young as Triassic. Further development of the deposits is unlikely under present economic conditions because of their generally low gold content and because much of the vein system lies on park property, but study of the Great Falls vein system may be useful in the search for similar deposits elsewhere in the Appalachian Piedmont.
