A Comparison Of The Silver Losses Due To Cupellation Using Different Kinds Of Cupels, James A. Taggart, Anton Frederick Karte Jan 1911

A Comparison Of The Silver Losses Due To Cupellation Using Different Kinds Of Cupels, James A. Taggart, Anton Frederick Karte

Bachelors Theses

"In this thesis our object has been to ascertain the silver losses in cupellation with different kinds of cupel materials, thereby determining the efficiency of the various materials used for making cupels. When beginning this work we hardly expected to find such differences in behavior of the various cupels used. However we refer the reader to our curves to see what really happened"--page 2.


A Sanitary Study Of The Well Waters Of Rolla, Alexander Grosberg, Sam Paul Lindau Jan 1911

A Sanitary Study Of The Well Waters Of Rolla, Alexander Grosberg, Sam Paul Lindau

Bachelors Theses

"In undertaking the analysis of the well waters of Rolla, it was done with the hope that the factors governing the purity of well waters would be brought out. Such a study would also be of great help in determining the proper location and depth of the wells in the community"--Introduction, Page 1.


A Summary Of The Theories Of The Origin Of The Lake Superior Copper Ores, With Evidences Pertaining Thereto, Eva Endurance Hirdler Jan 1911

A Summary Of The Theories Of The Origin Of The Lake Superior Copper Ores, With Evidences Pertaining Thereto, Eva Endurance Hirdler

Bachelors Theses

"In each of the foregoing theories we obtain sound reasoning in connection with many facts. Therefore a correlation of these facts ought to give us enough material to deduct a sound theory. The most plausible supposition seems to be that all metallic ores are derived ultimately from the interior of the earth, from a great metallographic province, when they are delivered by igneous eruptives near or at the surface"--Conclusion With Reasons, page 29.


Evidence Pertaining To The Origin And Deposition Of Ore Deposits, James Edward Mcgoughran Jan 1911

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 Aug 1910

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.

A Comparison Of Various Methods Of Assaying Cyanide Solutions For Gold, Theodore Saunders Dunn Jan 1910

A Comparison Of Various Methods Of Assaying Cyanide Solutions For Gold, Theodore Saunders Dunn

Bachelors Theses

"Although there has been a great deal written on the different methods of assaying cyanide solutions and new methods are being devised constantly there has been very little said as to the relative merits of the methods in use. An attempt has therefore been made in this paper to compare several of the methods now used"--page 1.


A Study Of Some Problems In Cyaniding, Sidney S. Schmidt, Russell B. Caples Jan 1910

A Study Of Some Problems In Cyaniding, Sidney S. Schmidt, Russell B. Caples

Bachelors Theses

"The object of the following tests was rather to determine quantitatively the consumption of Potassium Cyanide and of Sodium Cyanide when agitated by compressed air, and when agitated by compressed air in the presence of iron pyrite and in the presence of iron filings, than to explain chemically the causes for this consumption"--Part One, page 1. "The following tests were made to study the rate of percolation of water, under certain conditions, through pure quartz. the information sought is of importance in the cyanide process. By "rate of percolation" we mean the distance traveled in a unit time, by water …

An Investigation Of Certain Methods For The Determination Of Gold In Cyanide Solutions, James Joseph Bowles

Bachelors Theses

"Some questions having been raised as to the reliability of the various methods for the quantitative determination of gold in cyanide solution, this work was undertaken with the view of determining the relative accuracy and convenience of these methods"--page 2.

Coal In Nebraska, Roy V. Pepperberg Jan 1910

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 Cretadeous formations.


Bulletin No 32 - Noxious Weeds And Poison Plants, Department Of Agriculture, Western Australia Jan 1910

Bulletin No 32 - Noxious Weeds And Poison Plants, Department Of Agriculture, Western Australia

Bulletins 1 - 2999

Many settlers, new to this State, find some difficulty in distinguishing those vegetable pests which are classed as noxious weeds, the eradication of which is made compulsory under the Noxious Weeds Act of 1904.

In order to facilitate the ready recognition of the plants which are the least familiar, the Department of Agriculture has prepared this Bulletin, giving illustrations of the several varieties which have been gazetted as noxious. these are: - Stinkwort, Bathurst Burr, Noogoorn Burr, Nut Bramble, Spanish Radish, Prickly Pear, Apple of Sodom, sweet Briar, Wild Bramble, Star Thistle (purple), Double Gee and Water hyacinth.

Preliminary Notes On The Carboniferous Flora Of Nebraska, Roy V. Pepperberg Jan 1910

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.


Bulletin No. 106 - A Study Of The Production And Movement Of Nitric Nitrogen In An Irrigated Soil, Robert Stewart, J. E. Greaves Dec 1909

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.
