Cross-Bedding In The White River Formation Of Northwestern South Dakota, Dean E. Winchester Jan 1913

Cross-Bedding In The White River Formation Of Northwestern South Dakota, Dean E. Winchester

United States Geological Survey: Staff Publications

Rocks of White River (Oligocene) age have been known for many years to constitute numerous isolated buttes and mesas in the northwest corner of South Dakota, but no detailed study of their character and structural relations had been made until 1911, when, during an examination of the lignite area of that country, the writer had occasion to study the relation of the younger rocks to those containing lignite beds.

Todd, in 1895, recognized the White River formation in the Slim Buttes and called attention to the area in the following language:

3. Miocene beds, both White River and Loup Fork, …


Cement Manufacture In Nebraska, Erwin Hinckley Barbour Jan 1913

Cement Manufacture In Nebraska, Erwin Hinckley Barbour

Conservation and Survey Division: Faculty and Staff Publications

It is the purpose of this paper to briefly review the history of cement manufacture in the State, to call attention to certain promising exposures of cement rock, and to report upon the first modern cement mill in Nebraska. Not that this State has been slow in recognizing cement as one of the most important modern constructional materials; or slow to recognize the need of developing its natural resources; but due rather to a combination of circumstances. For at least twenty years, many Nebraskans have had in mind the importance of establishing cement plants in this State. Furthermore encouraging inducements …

Notice Of Newly Discovered Eurypterids In Nebraska, Erwin Hinckley Barbour Nov 1912

Notice Of Newly Discovered Eurypterids In Nebraska, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

A BED of Eurypterids has just been discovered by the Nebraska Geological Survey in the Carboniferous shales of southeastern Nebraska, and thus a new locality is added to the list for the United States. Such localities are somewhat rare, and notice of any and every new one must be acceptable.

The Carboniferous outcrops are confined to some eight or ten counties in the extreme southeastern corner of the state, and though covered heavily by glacial clays, bold exposures occur in proximity to the bolder streams, especially the Missouri River. About a mile south of Peru, on the Missouri River front, …


Bulletin No. 115 - The Movement Of Water In Irrigated Soils, J. A. Widtsoe, W. W. Mclaughlin May 1912

Bulletin No. 115 - The Movement Of Water In Irrigated Soils, J. A. Widtsoe, W. W. Mclaughlin

UAES Bulletins

This bulletin embodies a part of the data secured in the irrigation investigations of this Station. It aims to contribute something to our knowledge of the movement of water in irrigated soils . The science of irrigation can not well be built until the laws involved in the mutual relationships of waters, soils and crops are understood with fair accuracy. Much has been done by numerous investigators, during the last fifty years, to give a clearer comprehension of the movement of soil moisture; but the field experiments have dealt largely with saturated soils, and the laboratory experiments have seldom taken …

Bulletin No. 114 - The Movement Of Nitric Nitrogen In Soil And Its Relation To "Nitrogen Fixation", Robert Stewart, J. E. Greaves Dec 1911

Bulletin No. 114 - The Movement Of Nitric Nitrogen In Soil And Its Relation To "Nitrogen Fixation", Robert Stewart, J. E. Greaves

UAES Bulletins

In the spring of 1903, we commenced at the Utah Experiment Station a series of experiments, the purpose of which was to study the development and movement of nitrates in irrigated soil. The work was so outlined that it should give some very definite results, both as to the influence of water and the plant, upon the nitric nitrogen content of the soil.

Bulletin No. 109 - The Nitrogen And Humus Problem In Dry-Land Farming, Robert Stewart Aug 1910

Bulletin No. 109 - The Nitrogen And Humus Problem In Dry-Land Farming, Robert Stewart

UAES Bulletins

The effect of cultivation and the growth of crops upon the nitrogen and humus content of soils has been studied by various investigators, both in America and Europe. In general, the results of the various investigations indicate that cropping and cultivation are very destructive of the organic. matter and the nitrogen of the surface soil.

Coal In Nebraska, Roy V. Pepperberg Jan 1910

Coal In Nebraska, Roy V. Pepperberg

Conservation and Survey Division: Faculty and Staff Publications

Until February, 1906, Nebraska was termed "the state without a mine," and may still be called the state with but a single mine, and yet it would be impossible to tell how much prospecting has been done, or to estimate the number of thousands of dollars that have been spent in this state trying to develop paying mines from the thin beds of coal discovered throughout various parts of the state in the Carboniferous and Cretadeous formations.


Preliminary Notes On The Carboniferous Flora Of Nebraska, Roy V. Pepperberg Jan 1910

Preliminary Notes On The Carboniferous Flora Of Nebraska, Roy V. Pepperberg

Conservation and Survey Division: Faculty and Staff Publications

About the middle of July, 1907, while engaged by the Nebraska City Commercial Club in examining the geology of Nebraska City and vicinity, the writer was called b the farm of Mr. C. B. James to look at a bed of what was supposed to be fire clay. This proved to be a Carboniferous deposit of stratified micaceous sandstone, interstratified with a fine compact shale, both of which are yellow in color and very fragile when wet.
