Bachelors Theses

"The object of this thesis has been a systematic research based on the characteristic properties and reactions of mono-calcium phosphate, Ca H₄ (PO₄)₂, tending towards the development of a process for neutralizing the free phosphoric acid, H₃PO₄ formed during its manufacture"--page 1.


Wells And Windmills In Nebraska, Erwin Hinckley Barbour Jan 1899

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 Jan 1898

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 Jun 1895

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 Dec 1892

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 Apr 1892

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. May 1890

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 Jan 1890

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 Oct 1888

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 …

Some Impurities In Drinking Water, George Weitbrecht Dec 1880

Some Impurities In Drinking Water, George Weitbrecht

Journal of the Minnesota Academy of Science

The more we know about the causes of disease the more we are convinced that many of the ills that flesh is heir to come to us through germs that are transmitted through the air we breath, the water we drink and the food we eat. You are all familiar with the westward march of cholera among men and epizooty among animals. In surgical operations the danger is not from the operation, but from germs which are in the air and which get into the body through the wound, producing surgical fever, etc. Since Lester used the carbolic acid spray …

The Ancient Copper Mines Of Isle Royale, N. H. Winchell Dec 1880

The Ancient Copper Mines Of Isle Royale, N. H. Winchell

Journal of the Minnesota Academy of Science

Two papers were read in 1880, by Prof. Winchell, on the ancient copper mines of Isle Royale. After an account of the exterior phenomena of the mines, and an enumeration of the articles found in them, an inquiry was instituted as to the race that wrought them, and as to their relation to the Mound Builders, and to the Indians. As it has been admitted for several years that the Lake Superior miners were identical with the Mound Builders, the inquiry involved the examination of the relation of the Mound Builder to the present Indian. The characteristics of the Mound …
