Assay Of Copper Matte For Gold And Silver, Walter E. Soest

Bachelors Theses

"Ores containing copper, and especially copper matte, have always been very annoying in assaying for the precious metals. In assaying copper matte, and ores containing much copper, by the usual method of scorification, the losses of silver an gold are considerable, owing to the fact that in order to obtain lead buttons, which are soft and free from copper, repeated scorifications are necessary, and moreover it is impossible to obtain lead buttons which are entirely free from copper"--page 1.

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 …

The Neocene Lake Beds Of Western Montana And Descriptions Of Some New Vertebrates From The Loup Fork, Earl Douglass

Graduate Student Theses, Dissertations, & Professional Papers

Since coming to Montana in the spring of 1894 I have spent rnuoh of ay time in studying the lake bed deposits in the western part of the state, and in collecting and studying the vertebrate fossils found in them. These deposits occur in nearly every large valley in the westem part of the state. I have myself observed them in the valleys of the upper Missouri (above the re-rrion of Helena), Gallatin, Madison, Jefferson, Beaverhead, Ruby, Big Hole, Hell Gate, and Bitter Boot rivers, and their tributaries.

An Application Of Interference Mmthods To A Study Of The Changes Produced In Metals By Magnetization, J. S. Stevens

Physics and Astronomy Faculty Scholarship

Problems which have for their object a study of the changes produced in metals when magnetized have, during the past fifty years, received attention from physicists. It is thought that if a thorough investigation of the subject could be made, much light would be thrown upon the phenomenon of magnetization, and even the theory of the constitution of matter. Historical notes relating to this problem may be found in the Physical Review, Vol. III, No. 15, and Vol. V., No. 5. The results of various investigators agree fairly well as to the maximum elongation of a rod or wire when …

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. 47 - The Climate Of Utah, James Dryden

UAES Bulletins

In reporting the meteorological observations of the Station for the years 1895 and 1896, it has been thought well to include for purposes of comparison records of temperature and precipitation at several other Utah points, as well as other data of climatological importance. The bringing together of all the known facts of our climate is a work of necessity that has been too long neglected. Observers have been patiently collecting data, some of them for a quarter of a century or more, and of the mass that has been collected very little is known outside of the periodical records of …

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.

The Occurrence In Nebraska Of Vireo Flavoviridis, Erwin Hinckley Barbour

A specimen of the Yellow-green Vireo, Vireo flavoviridis, shot at Long Pine, Brown County, has just been received by the Curator of the Museum of the University of Nebraska. This is the first one reported in this State. It is a rare Vireo for the entire United States having been reported, as far as the author can learn, from Texas, California, and Canada only.

A Two-Headed Tortoise, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

INQUIRIES from various quarters have been made so repeatedly for the sequel to the brief story of a young two-headed tortoise, Chrysemys picta, published in the American Journal of Science for October, 1888, that the author is led to believe that a public account thereof will serve more useful ends than many private ones. In order that the sequel may be more intelligible to all, a brief resume of the first paper will be given.

The young tortoise, hatched but a day or so, was found in the marshes bordering West River, New Haven, Conn. The carapace, which was somewhat …

Report Of The Geologist, Erwin Hinckley Barbour

THE PROBLEM OF OUR SOILS AND SOIL MOISTURE.

The soil survey of the state, which was begun by the author in November of 1892, has progressed to the point where it might be considered finished. That is, one or more samples of soils have been taken from every distinct soil region in the state-in fact, most of the separate counties are represented, and mechanical analyses of many of these have already been made. However, in consideration of the size of our counties, the work will not be declared complete until each is represented in the state museum by soil prisms …

Lincoln Salt Lake And The Occurrence Of Strepsilas Interpres, Erwin Hinckley Barbour

Department of Earth and Atmospheric Sciences: Faculty Publications

Local ornithologists are considerably interested in the occurrence of the Turnstone (Strepsilas interpres) in this State. Three were shot at Lincoln Salt Lake on the 25th of May of this year. These were secured by Mr. W. D. Hunter of the Department of Taxidermy, and were placed by him in the State Museum. This is the first authentically reported occurrence of this bird in Nebraska. So far as we can learn it is not reported for any of our neighboring States.

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 …
