A New Longisrostral Mastodon From Cherry County, Nebraska, E. H. Barbour
A New Longisrostral Mastodon From Cherry County, Nebraska, E. H. Barbour
Conservation and Survey Division
During the season of 1914, field work in the fossil regions was pushed less vigorously than usual owing to lack of funds. N evertheless some interesting and valuable material was obtained by the N ebraska Geological Survey, notably the great mandible of a new longirostral mastodon from Cherry County, together with associated tusk and bones.
The mastodon constituting the basis of this paper was found in the exposnres bordering the Snake River in section 33, range 30 west, and township 32 north. The talus slope was strewn with fragments of the tusk and bone of a mastodon. This led the …

A Working Plan For The Woodlands Of The New Haven Water Company; Prepared After Five Years Of Forest Practice, 1908 To 1912, Ralph C. Hawley
A Working Plan For The Woodlands Of The New Haven Water Company; Prepared After Five Years Of Forest Practice, 1908 To 1912, Ralph C. Hawley
Yale School of the Environment Bulletin Series
Soon after the establishment of the Yale Forest School in 1900, the necessity developed for finding forest lands near the city of NewHaven upon which to conduct field work. It was found that many of the most accessible and best timbered tracts were owned by the New Haven Water Company....about 250 acres near the Maltby Lakes were placed under the management of the Yale Forest School. ...a written plan is desirable. The plan is divided into two parts: the first, descriptive of present conditions and passt accomplishments; the second, treating of the policy to be pursued.
Studies On The Relation Of The Nonavailable Water Of The Soil To The Hygroscopic Coefficient, F. J. Always
Studies On The Relation Of The Nonavailable Water Of The Soil To The Hygroscopic Coefficient, F. J. Always
Nebraska Agricultural Experiment Station: Historical Research Bulletins
These experiments were carried out in connection with and subordinate to various soil investigations, the object being to determine the relation of the final water content of the soil to the hygroscopic coefficient and to determine to what extent the moisture was removed from the different portions of the subsoil not penetrated by plant roots.
Cross-Bedding In The White River Formation Of Northwestern South Dakota, Dean E. Winchester
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, …
Bulletin No. 122 - The Nature Of The Dry Farm Soils Of Utah, John A. Widtsoe, Robert Stewart
Bulletin No. 122 - The Nature Of The Dry Farm Soils Of Utah, John A. Widtsoe, Robert Stewart
UAES Bulletins
Successful farming in Utah is dependent upon two main factors: First, the economic use of irrigation water upon the lands lying under the irrigation ditch, and second, upon the correct practice of the principles of dry farming upon those lands not susceptible to irrigation. Dry farming in Utah is, therefore, of great importance and it becomes essential to learn something of the nature of the dry farming soils of the State.
Bulletin No. 121 - The Soil Of The Southern Utah Experiment Station, John A. Widtsoe, Robert Stewart
Bulletin No. 121 - The Soil Of The Southern Utah Experiment Station, John A. Widtsoe, Robert Stewart
UAES Bulletins
The soil of the Southern Utah Experiment Farm is a very interesting type: it is highly charged with gypsum and thereby presents a condition unique in reported studies of the soils of America. Gypsiferous soils are characteristic of a large portion of Southern Utah; many of them are derived from shale, others from sandstone, impregnated with gypsum.

Cement Manufacture In Nebraska, Erwin Hinckley Barbour
Cement Manufacture In Nebraska, Erwin Hinckley Barbour
Conservation and Survey Division
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
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
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
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.
