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.

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.

Evidence Pertaining To The Origin And Deposition Of Ore Deposits, James Edward Mcgoughran

Bachelors Theses

"In looking over the evidence grouped in the foregoing tables it is at once evident that by far the greater number of the ore deposits are associated with igneous rocks, and that they have resulted from deposition from not solution. It appears that, relatively, deposition by segregation from an igneous magma is of much less importance than deposition from solution, in the formation of ore bodies. However, segregation is the only explanation possible in accounting for some very important deposits, but they are very few in number. In distinguishing between deposits resulting from hot ascending meteoric solutions and those resulting …

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.

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.

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 Cretaceous formations.

Bulletin No. 106 - A Study Of The Production And Movement Of Nitric Nitrogen In An Irrigated Soil, Robert Stewart, J. E. Greaves

UAES Bulletins

The problem of maintaining the nitrogen content in our agricultural soils is one of vital importance to the development of a permanent system of agriculture. Any investigation, therefore, which tends to throw any light on the conditions which are necessary for maintaining the maximum supply of nitrogen in our soils needs no apology for its institution.

Bulletin No. 104 - The Storage Of Winter Precipitation In Soils, John A. Widtsoe

UAES Bulletins

It has been found that the production of one pound of dry plant substance on soils of average fertility, requires in humid districts not more than five hundred pounds of water, and in arid districts like Utah about seven hundred and fifty pounds. This indicates that the average rainfall of Utah, which is about twelve inches, if properly conserved in the soil, is sufficient to produce annually, without irrigation, from thirty to forty-five bushels of wheat to the acre, or corresponding yields of other crops. The realization of this truth has changed greatly our views of irrigation practices. The beginning …

Skeletal Parts Of Moropus, Erwin Hinckley Barbour

Conservation and Survey Division: Faculty and Staff Publications

In the foregoing publication, it was announced that the skull of Moropus had been discovered. Heretofore the genus had been known chiefly by scattered teeth and fragments, mostly toe bones, but now that the collections of Hon. Charles H. Morrill, Nebraska State Museum, have the skeletal parts necessary for the restoration of this remarkable animal, it seems advisable to supplement the brief illustrated report concerning the skull of Moropus with a similar paper concerning its skeletal parts.

The Skull Of Moropus, Erwin Hinckley Barbour

Conservation and Survey Division: Faculty and Staff Publications

During the summer of 1905 the Morrill Geological Expedition of the University of Nebraska had the good fortune to discover early in July the skull of Moropus. Associated with it were mandible, atlas and other cervicals, and various skeletal parts.

Evidence Of Man In The Loess Of Nebraska, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

After careful investigation the writer stands ready to announce his belief in the occurrence of human remains in the loess of this state, and for this primitive type he has proposed the name Nebraska Loess Man. Such importance attaches to the discovery as to warrant a paper devoted to the geological facts connected therewith.

Biennial Report, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

The Nebraska Geological Survey as now constituted has been in operation since 1891, but it has enjoyed state aid during the past four years only. Considering the size of the commonwealth and the limited appropriations for geological work, unusual progress has been made. Since no report covering the work of the first biennium was prepared it will be included incidentally in this paper. Briefly stated the Nebraska Geological Survey during the past biennium has devoted especial attention to the industrial resources of the state, prepared ten o! twelve reports in manuscript form, published eight reports completing volumes I and II, …

Opening Of The Indian Territory, G. E. Condra

Conservation and Survey Division: Faculty and Staff Publications

The opening of Indian country has continued from Colonial days to the present. Usually it has resulted from force and treaty, the strong dispossessing the weak. As a result, the Red man has, in general, moved frontierward, ahead of industrial waves, remaining for a longer time only on reservations set aside for tribes. The Indian's struggle even on these reserves has been a losing one, resulting largely from war, disease, and the cupidity of whites. History shows that Indian life and Indian institutions have not prevailed against the white man's civilization and commerce. GATHERING THE TRIBES. The Indian Territory and …

Notice Of A New Miocene Rhinoceros, Diceratherium Arikarense, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

THE accompanying sketches represent the skull of a species of rhinoceros, Diceratherium arikarense, supposedly new, discovered by the geological expedition of 1905, sent from the University of Nebraska by the Hon. Charles H. Morrill to the Loup Fork beds at Agate, Nebraska, on the ranch of Mr. James Cook.

The genus Diceratherium was established by Marsh in 1875 on material from the Miocene beds near the John Day River in eastern Oregon, and two species, armatum and nanum, were recognized. A third species, advenum, was based on material from the Eocene (possibly Miocene) of Utah. Difference of horizon, …

Report Of The Tenth Geological Expedition Of Hon. Charles H. Morrill, Season Of 1905, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

The season of 1905 marked a renewal of paleontological activity in the University of Nebraska, since it so happened that for the first time in several years funds became available again for the prosecution of such work.

By virtue of the liberal support and patronage of Hon. Charles H. Morrill, of Lincoln, annual geological expeditions, essentially paleontological in character, had been maintained in connection with the state university since 1892. In 1901, though his interest in the work AS well as his good will continued, his patronage ceased. This was wholly due to the overcrowded condition of the state museum, …

The Morrison Formation And Its Relations With The Comanche Series And The Dakota Formation, T. W. Stanton

United States Geological Survey: Staff Publications

The beds now generally designated on U. S. Geological Survey maps as the Morrison formation have been a subject of interest and discussion since I877, when abundant remains of dinosaurs were found in them. The first extensive collections of the vertebrate fauna were obtained in the neighborhood of Morrison near Denver, -in Garden Park, near Canyon City, Colorado, and at Como, or Aurora, Wyoming. Since then the formation has been recognized by means of its fossils, its lithologic features, and its stratigraphic relations in the Black Hills, on the Laramie Plains, and elsewhere in Wyoming, in Montana, in western Colorado, …

Bulletin No. 89 - A New Centrifugal Soil Elutriator, P. A. Yoder

UAES Bulletins

Within recent years much has been done toward determining the agricultural significance of certain physical properties of the soil. The grade of fineness is the most important of these physical properties, in that it determines, to a large extent, other properties. The· mechanical analysis of soils has thus come to be considered of primary importance in soil investigations. Any improvements in the methods or apparatus for mechanical analysis will, therefore, doubtless be welcomed by agricultural investigators. Though this is a very recent line of work, still many devices have been introduced for the separation of soil on the basis of …

Present Knowledge Of The Distribution Of Daimonelix, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

Daimonelix when first discovered, in 1891, was thought to be confined to the elevated tablelands of central Sioux County, Nebraska. In the meantime its range has been extended and it is now known almost throughout the entire Arikaree formation, a tract probably about five hundred miles in diameter, situated in Nebraska, Kansas, South Dakota, Wyoming and Colorado. The more fibrous forms of Daimonelix constitute a character so constant as to justify the name Fibrous Arikaree for the upper half of the formation.
