A New Longisrostral Mastodon From Cherry County, Nebraska, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

During the season of 1914, field work in the fossil regions was pushed less vigorously than usual owing to lack of funds. Nevertheless some interesting and valuable material was obtained by the Nebraska Geological Survey, notably the great mandible of a new longirostral mastodon from Cherry County, together with associated tusk and bones.

A New Longisrostral Mastodon From Cherry County, Nebraska, E. H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

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 …

Two New Fossil Dogs Of The Genus Cynarctus From Nebraska, Erwin H. Barbour, Harold J. Cook

Conservation and Survey Division: Faculty and Staff Publications

The genus Cynarctus was founded by Dr. W. D. Matthew on a nearly complete pair of lower jaws from the Pawnee Creek Beds (Middle Miocene) of Colorado, found in 1901. Since that time no new material pertaining to this genus has been reported. Dr. Matthew referred the genus to the subfamily Amphicyoninae, and to a position intermediate between the primitive bear Ursavus, and the Canidae, with primitive characters retained from its Oligocene ancestors.

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.

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

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

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 …

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.

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.
