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.

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.

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.

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.

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.

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 …

A Workable Bed Of Coal In Nebraska, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

ALTHOUGH for years past the state legislature of Nebraska has offered a bounty amounting to four thousand dollars for the discovery of a twenty-six-inch bed of workable coal, and five thousand for a thirty-six-inch bed, it is only within the past few days that any one has filed with the governor legitimate claims for the bounty. The bed of coal recently exposed, near Peru, Neb., extending some forty-two feet along the sides of a tunnel back from the banks of Honey Creek, seems to be fully thirty-four inches in thickness, as measured by the writer. This is known as the …

A New Miocene Artiodactyl, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

AMONG several discoveries made in the Daimonelix beds (Loup Fork) of Sioux County, Nebraska, the most striking one of the season seems to be that of a new four-horned ancestral antelope, Syndyoceras cooki, the skull of which is herein figured and briefly described. The discovery was made by Mr. Harold G. Cook, a former Lincoln student and a member of the Morrill geological expedition of 1905.

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 …

Wells And Windmills In Nebraska, Erwin Hinckley Barbour

United States Geological Survey: Publications

SIR :

I have the honor to transmit herewith a manuscript entitled "Wells and Windmills in Nebraska," prepared by Erwin Hinckley Barbour, professor of geology in the University of Nebraska and acting State geologist. The data for this manuscript were obtained by Professor Barbour incidental to his studies of the geology of the State, and have been rounded out by special work carried on under his direction. The original manuscript as prepared consisted of two parts the first upon wells, and the second upon homemade windmills but owing to delays in printing the first part, it has been considered advisable …

Bulletin No. 52 - The Chemical Composition Of Utah Soils (Cache And Sanpete Counties), John A. Widtsoe

UAES Bulletins

The soils of the State [Utah], as found by the Mormon pioneers of 1847, were virgin in the fullest sense of the word. As far as man knows, only a few patches in Southern Utah had ever been cultivated. For untold centuries the atmospheric forces, unhindered by man's intervention, had been allowed to weather and make fit for agricultural purposes the rock fragments that, washed down into the valleys from the mountain ranges, constitute the soils of the State. For a long period, also, long before human tradition begins, there had not been enough water in the Utah valleys to …

Bulletin No. 46 - Earthen Dams, Samuel Fortier

UAES Bulletins

According to the last census, 92 1/2 per cent of the Utah farms are irrigated. The advancement of agriculture in this State mainly depends upon the water, the available supply of which, in many of the older settled localities of the State, is already wholly utilized during the irrigation period. The future reclamation of new lands in such localities must, therefore, wait on the development of new sources of supply from storage reservoirs, sub-surface supplies, or from a more economical use of the summer flow of the available streams.

From estimates and measurements made by the hydrographers. of the United …

Is Daemonelix A Burrow?: A Reply To Dr. Theodor Fuchs, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

Dr. Theodor Fuchs, criticises at considerable length the nature of Daemonelix as described by the author, in the University Studies, of the University of Nebraska, Vol. I, No. 4, July, 1892, under the title, 'Notes on a New Order of Gigantic Fossils.' When the criticism first appeared it seemed so fraught with errors that they were counted its own best rebuttal, and no attempt to frame a reply was thought of. However, the author has several times of late been reminded that these errors might pass muster and become fixed in the minds of those, at least, who place too …

Notice Of The Occurrence Of Nyctale Richardsoni, Richardson's Owl, In Nebraska, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

THE occurrence in this region of Richardson's owl, Nyctale Richardsoni, seems to be entirely established by the recent capture of one in Lincoln. This is a long distance below its southern limit, and its appearance is something of a surprise.

Attempted Extermination Of The Pocket Gopher, Geomys Bursarius, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

The ravages of the pocket gopher extended very generally throughout the State of Iowa, but came under my own personal notice in the rich and fertile farm lands of Poweshiek County and surroundings. The annual loss they occasioned became a matter of such serious moment to the farmers of this county that on Jan. 8, 1890, an unusually liberal measure was voted by the board of supervisors, to the effect that "a bounty of ten cents a head be paid on gopher scalps taken in Poweshiek County, subject to the same laws and conditions that pertain to the payment of …

The Winnebago County (Iowa) Meteorites, George F. Kunz, Erwin Hinckley Barbour, Joseph Torrey Jr.

Department of Earth and Atmospheric Sciences: Faculty Publications

A remarkable meteor, or meteoric shower, passed over this State at 5.30 P.M., Friday, May 2. In spite of the brightness of the sun, shining at the time in a nearly cloudless sky, the light of the meteor was very noticeable. Its great size, powerful illumination, discharge of sparks, comet-like tail three to five degrees in length, and the great train of smoke which marked its course for a full ten minutes after its passage, made a strong and lasting impression on the minds of all who saw it. Unfortunately the clamor over an exciting game of ball prevented the …

Remains Of The Primitive Elephant Found In Grinnell, Iowa, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

The one alluded to was found in 1884, while breaking ground for the Eagle Block, on the north-east corner of Main Street and Fourth Avenue. This animal, a large adult male, is represented by a tusk (eight feet long and nine inches in diameter), several grinders, lower jaw, and part of zygomatic arch, preserved in the museum of Iowa College. These bones occurred about five feet below the surface, and were in an exceedingly soft and perishable condition, as similarly situated remains usually are; but, owing to the skill of Professor H. W. Parker, the tusk and teeth especially were …

On A Young Tortoise, Chrysemys Picta, With Two Heads, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

THE following is a brief description of a young two-headed tortoise, Chrysemys picta, which is a remarkably interesting specimen from the very perfection of its imperfection. It was found in the marshes bordering West River in New Haven, Conn., by Master Leighton Foster, the first part of June, and from appearances had been hatched but two or three days. The single body, with the usual four legs and a tail, carries two equal, and in every respect, normal and well-developed heads and necks, which are throughout entirely free and distinct. The two heads see, hear, eat, drink, sleep, breathe, and …
