Plan Of Development For Valley Gravity Project, Julius A. Krug, Michael W. Straus, Wesley R. Nelson
Lower Rio Grande Valley Curated Material
"The Valley Gravity Project Plan has been formulated to furnish an adequate and dependable irrigation water supply for fertile and productive area in the Lower Rio Grande Valley, Texas, It would also provide drainage works, which would remove the threat of destruction of the economy of the area due to effects of a high water table and salt accumulations. The project works would permit generation of the maximum practicable amount of electrical energy which otherwise would be required to operate irrigation pumping plants. Other incidental benefits include fish and wildlife conservation, recreation and flood control."

Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott
Fifty Years Of Achievement In Agricultural Investigation, R. T. Prescott
Nebraska Agricultural Experiment Station: Historical Circulars
In Nebraska, a hustling frontier state in 1887, the legislature hesitated not at all in taking advantage of the provisions of the Hatch Act, and now that fifty years have elapsed since the Station was founded, seventy-five years since the Land Grant College Act was passed and the U. S. Department of Agriculture established, and almost twenty-five years since the Agricultural Extension Service was added, it seems worth while to present a general summary of achievement within the state. The main object will be to show some of the important things that have been learned through the investigations of the …
Organization Of Geophysical Parties For Foreign Exploration, Charles Howard Dresbach
Organization Of Geophysical Parties For Foreign Exploration, Charles Howard Dresbach
Professional Degree Theses
"Special conditions encountered in much foreign work make it necessary to consider many factors which are not encountered in domestic programs of geophysical exploration for oil. Although extremely difficult working conditions are frequently met in domestic operations by company and contract crews, the large store of past experience, the availability of fresh supplies, replacement or new equipment, and the proximity of the helpful home office make their surmountal more or less a matter of routine. Contrariwise, foreign operations are frequently conducted under much more difficult conditions, supplies and equipment can be secured only after long and costly delays, and the …
Underground Stratigraphy Of Montana, Virgil R. Chamberlain
Underground Stratigraphy Of Montana, Virgil R. Chamberlain
Bachelors Theses and Reports, 1928 - 1970
The purpose of this thesis is to study the subsurface stratigraphy of the state of Montana from information acquired from well logs, composite logs, and measured sections. Underground stratigraphy is important for the intelligent prospecting for oil, gas, or water. A knowledge of the strata beneath us can be gathered only by measurements of numerous outcrops or by deep drilling with careful sampling or logging of the formations passed through.

Commercial Mineral Waters Of North-Central Texas, Shirley Alfred Lynch
Commercial Mineral Waters Of North-Central Texas, Shirley Alfred Lynch
Professional Degree Theses
"The great increase in demand for mineral water the past few years has lead to the development of a new industry, the making of mineral water crystals. Wells that were abandoned as unsuitable for water supply, due to their salinity, have been cleaned or redrilled, in a frantic effort to supply the ever increasing demand of the crystal plants. The inevitable result is that their waters are being used at an alarming rate of consumption. The popular conception is that there is no end to the amount of charged waters that may be obtained, and, as a result, within some …
The U.S.G.S. Topographic Map: Its Value And Method Of Construction, Daniel Kennedy
The U.S.G.S. Topographic Map: Its Value And Method Of Construction, Daniel Kennedy
Professional Degree Theses
"Topographic maps, which differ from the base map in that they show not only relative distance and direction but also the accurate shape of the earths surface, are not new, but represent the constant improvement in mans efforts to reproduce on paper all that he sees and knows of regions of the globe.
While history records the first maps known to man as being made by the Babylonians on clay tablets centuries before Christ, the first relief map was made by the Ninth Inca who died in the year 1191. The present method of showing relief by contours was employed …

The purpose of Part I of this report is to determine the origin of the bentonite deposits, also to locate them with reference to section corners in the vicinity and to determine their extent.
The field work for this report was done in the fall of 1933 and during the spring of 1934. The roads, geologic contacts, and culture in general were mapped with the use of an open sight alidade and plane table. Distances were determined on the roads by the speedometer on the automobile; the detailed survey in the immediate vicinity of the deposits was done with use …
Foundations For Aquatic Oil Wells, Henry Emmett Gross
Foundations For Aquatic Oil Wells, Henry Emmett Gross
Professional Degree Theses
"During the past decade, man has found the courage to drill for oil at those forbidding locations which were made inaccessible by several feet of water. Some of the major fields of the world have been developed by this new manner of work, and others might have been added had the stage been set for the play. The most spectacular marine oil field development occurred along the Santa Barbara Coast of California from 1929 to 1931. It was the writer's good fortune to have been an assistant to Mr. Hans E. A. Gude, the field engineer of Pacific Western Oil …
The Calcite Veins Of The Livingston Formation, John Moore Conrow
The Calcite Veins Of The Livingston Formation, John Moore Conrow
Bachelors Theses and Reports, 1928 - 1970
An interesting group of calcite veins occur near Livingston Montana in a zone about eight miles wide and forty miles long in the edge of the Plains region of Montana in front of the Main ranges. The zone extends from the Boulder River south of Big Timber, through Springdale and Hunters Hot Springs, to Potter's Basin just north of Wilsall in Park County. The group of veins is particularly interesting because they cut relatively flat lying strata, suggest a structural relationship to one another, and they are nearly pure calcite.
The present investigation was to determine the position of the …

The Chromite Deposits Of Stillwater And Sweetgrass Counties, Montana, Uuno Sahinen
Bachelors Theses and Reports, 1928 - 1970
In writing this report, two objects were kept in mind, (1) to explain, if possible, the origin of the chromite deposits found in Sweetgrass and Stillwater Counties, and (2) to bring up to date all information on these deposits which had thus far been available.
The work done consisted of study of the rocks and ores of the area under the microscope, both as thin sections and as polished sections, practically all of which was done at the Montana State School of Mines, during the school year of 1928 - 1929.
The rock specimens and much information as to their …
The Movement Of Ground Water And Its Relation To The Drainage Of Irrigated Lands, Ernest O. Larson
The Movement Of Ground Water And Its Relation To The Drainage Of Irrigated Lands, Ernest O. Larson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
One needs but to review the history of the irrigated projects of the West to see clearly the importance of drainage. Since the passing of the Reclamation Act in 1902, the construction of drainage work by the United States Reclamation Service on seventeen projects located in thirteen western states represents about 12 percent of the expenditures from the Reclamation Fund. The portion for drainage has been spent during the last few years. This work has required an annual expenditure of about $1,000,000 or a total of $8,000,000 to July, 1922(1). The work completed is estimated to have reclaimed …
Graphics And Its Application To The Progress And Cost Analyses Of A House Building Construction Company, Frank Lewis Leonard Wilson
Graphics And Its Application To The Progress And Cost Analyses Of A House Building Construction Company, Frank Lewis Leonard Wilson
Masters Theses
"In the graphical analyses of Stresses in Framed Structures, we study, by means of diagrams, the stability or equilibrium of structures and the relation between the external forces and the stresses created in the members of the frame. The principle involved is that we may represent any force both as to direction and intensity by a straight line, by considering the direction of the line to be identical with that of the force and adjusting its length according to any arbitrary unit adopted for the forces under consideration. By this means we can solve the stresses in framed structures with …
Mining Methods And Geology Of The Boston Consolidated Mine At Bingham, Utah, James Leonidas Boucher
Mining Methods And Geology Of The Boston Consolidated Mine At Bingham, Utah, James Leonidas Boucher
Bachelors Theses
"This thesis does not so much attempt a detailed report on the geology of the disseminates ores of Bingham Canyon as a more particular description of the underground methods of mining these ores as well as studies in drilling, sampling, etc. Steam shovel mining was studied to some extent but almost all the data for the following pages has been derived from the Boston Consolidated Underground Mine and the Old Utah Mine. The Boston consolidated, especially, has been studied for this mine is the largest and, at late date, was the only underground porphyry mine working, the Old Utah having …
Fluorspar Mining In Kentucky, Walter Coffran Richards
Fluorspar Mining In Kentucky, Walter Coffran Richards
Professional Degree Theses
"The mining of fluorite, or fluorspar in Western Kentucky is one of the chief mineral industries of that State. As the number of mines and prospects is very great, a thorough treatise on the geology, mines, and methods of this district would make a large volume. This thesis will deal, however, with only a small part of the district, in which the mine operated by the author is located. Before going into detail, it might be well to mention a few points relative to the fluorspar industry in general. To the average person, fluorspar seems to be unknown. In fact, …

Prospecting In Western Mexico, Theodore S. Delay
Prospecting In Western Mexico, Theodore S. Delay
Professional Degree Theses
"This article is dedicated and addressed to any man who contemplates a prospecting expedition in Mexico. I have made no attempt at a display of literary elegance, or scientific erudition. My aim has been to point out and explain such of the conditions of the business as are peculiar to Mexico. If any one, after having perused these pages, should find himself thereby the better able to cope with the difficulties of such an expedition, a rather unprofitable experience of the writer will have been not wholly fruitless"--page 31.
