The Middle Ordovician Section In East Central Missouri, Morris James Ingerson, Josiah Bridge

Masters Theses

"One of the most serious difficulties confronting anyone working on stratigraphic problems in the Ozark area is the lack of detailed faunal lists of the various formations. A great deal of general work has been done, but very few detailed faunal studies have ever been published, and correlation of the Missouri section with sections in adjoining states is often difficult.

In a recent paper, Dake has discussed the origin and correlation of the St. Peter sandstone. In this study he found considerable difficulty in correlating the various formations above the St. Peter, and at his suggestion, the present study was …

Bulletin No 81 - The Improvement Of Pastures With Notes On The Pasture Trefoils In Western Australia, E. A. Mann, D. A. Herbert

Bulletins 1 - 2999

Agriculture can be roughly divided for practical purposes into two large divisions, those of animal husbandry and vegetable husbandry. It is with the former that this pamphlet is chiefly concerned and its object is to contribute, it possible, in some small measure towards the problem of how to increase time stock carrying capacity of our natural pasture lands. it is unnecessary to dwell upon the importance of this question, especially in relation to the remarkable developments which are taking place in time wool-growing industry in the Southern and more coastal areas of Western Australia.

Rules For Official Tractor Tests, Nebraska Tractor Test Lab, Agicultural Experiment Station

Nebraska Tractor Tests

The Nebraska Tractor Law known as House Roll 85, 37th session, which became effective July 15, 1919, was enacted to encourage the manufacture and sale of imporved types of tractors and to contribute to a more successful use of the tractor for farming.

It was thought that the best method of accomplishing these objects would be to require a tractor of each model sold in the State to be tested at the State University and to have the results of these tests made public. These tests will give reliable information on the power capacity and fuel consumtion of each tractor …

Classification Of Springs, Kirk Bryan

United States Geological Survey: Staff Publications

Among the common phenomena of nature, springs are notable because of their high usefulness. Since the earliest times the homes of men have clustered around them. In arid regions their number and size may limit the population. In many humid regions springs are so numerous and similar that distinctions between them are not recognized, yet they may be caused by so many principal and minor factors or by so many combinations of these factors as to make the origin of any one spring exceedingly complex or obscure. An interesting account of the many erroneous notions held by the ancients regarding …

A Theorem On Semi-Continuous Functions, Henry Blumberg

Department of Mathematics: Faculty Publications

Recently G. C. Young and A. Denjoy have communicated theorems—those in Denjoy's memoir are of an especially comprehensive character—dealing, in particular, with point sets where the four derivatives of a given continuous function are identical. It is the purpose of this note to treat an analogous problem that arises when "derivative" is replaced by "saltus." However, instead of confining ourselves to "saltus," we prove a more general theorem that applies essentially to all semi-continuous functions. We preface the proof of this theorem with the following

Some Chemical Problems In Geology, Reginald Scott Dean

Masters Theses

"This thesis is in the main a compilation of the views held at this institution in regard to the problems discussed as interpreted by the author. No claims for originality are made except in the manner of presentation as the material used has been obtained by conference and class room work with Professor V. H. Gottschalk and Professor G. H. Cox and also to some extent with H. A. Buehler, State Geologist. On the other hand the material is an expression of these ideas as assimilated by the author and hence may in certain cases differ radically from the views …

Nebraska Green Quartzite An Import Ant Future Industry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

ln southern Harlan and Franklin counties, there occur many acres of green quartzite which must be of commercial consequence when made available. It is a neglected resource upon which important industries are sure to be based. With the development of this bed in view, the Nebraska Geological Survey has examined this area. and through this leaflet wishes to place the results before possible investors.

Nebraska Minerals Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

The Minerals, Rocks, and Fossils of Nebraska, which Excite Common Inquiry, are treated brefly in leaflets numbered 37, 37a, 37b, respectively. These are intended to serve as circular letters to correspondents. Possibly they may prove to be acceptable and helpful in a measure to teachers and others who conduct parties of school children on field excursions.

Nebraska Fossils Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

This paper must not be mistaken for a report on the fossils of Nebraska. It is merely a circular letter to correspondents describing and figuring those fossils only which occasion frequent comment. In two recent papers of the Survey consideration was given to the common minerals and rocks of Nebraska, and it seems opportune to briefly discuss our fossils in a like manner. Probably no other State can boast of such a well-preserved and varied fauna.

Nebraska Rocks Which Excite Common Inquiry, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

This leaflet it intended to serve as an answer to correspondents who make inquiry about the rocks of Nebraska¹. Unfortunately for those interested in such matters, the rocks of the State are few in number, and are deeply buried from view by sand and soil, so there are thousands of square miles in which even a pebble is a rarity. That our rocks are level and undisturbed is practically true. Still there are some surprisingly interesting folds and faults.

A New Longisrostral Mastodon From Cherry County, Nebraska, Erwin H. Barbour

Conservation and Survey Division: Faculty and Staff Publications

During the season of 1914, field work in the fossil regions was pushed less vigorously than usual owing to lack of funds. Nevertheless some interesting and valuable material was obtained by the Nebraska Geological Survey, notably the great mandible of a new longirostral mastodon from Cherry County, together with associated tusk and bones.

A New Longisrostral Mastodon From Cherry County, Nebraska, E. H. Barbour

During the season of 1914, field work in the fossil regions was pushed less vigorously than usual owing to lack of funds. N evertheless some interesting and valuable material was obtained by the N ebraska Geological Survey, notably the great mandible of a new longirostral mastodon from Cherry County, together with associated tusk and bones.

The mastodon constituting the basis of this paper was found in the exposnres bordering the Snake River in section 33, range 30 west, and township 32 north. The talus slope was strewn with fragments of the tusk and bone of a mastodon. This led the …

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.

Cross-Bedding In The White River Formation Of Northwestern South Dakota, Dean E. Winchester

United States Geological Survey: Staff Publications

Rocks of White River (Oligocene) age have been known for many years to constitute numerous isolated buttes and mesas in the northwest corner of South Dakota, but no detailed study of their character and structural relations had been made until 1911, when, during an examination of the lignite area of that country, the writer had occasion to study the relation of the younger rocks to those containing lignite beds.

Todd, in 1895, recognized the White River formation in the Slim Buttes and called attention to the area in the following language:

3. Miocene beds, both White River and Loup Fork, …

Cement Manufacture In Nebraska, Erwin Hinckley Barbour

Conservation and Survey Division: Faculty and Staff Publications

It is the purpose of this paper to briefly review the history of cement manufacture in the State, to call attention to certain promising exposures of cement rock, and to report upon the first modern cement mill in Nebraska. Not that this State has been slow in recognizing cement as one of the most important modern constructional materials; or slow to recognize the need of developing its natural resources; but due rather to a combination of circumstances. For at least twenty years, many Nebraskans have had in mind the importance of establishing cement plants in this State. Furthermore encouraging inducements …

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 …

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 …

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.
