Elephas Scotti A New Primitive Mammoth From Nebraska, Erwin Hinckley Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

On February 18,1922, the mandible of an unusually primitive mammoth was secured for the palaeontological collections of Mr. Hector Maiben by Mr. E. T. Engle. The specimen was found in Aftonian gravel on the farm of Mr. E. J. Hartman, five miles south of Staplehurst, Seward County, Nebraska. It is numbered 18-2-22 in the accession book of the Nebraska State' Museum.

Chapter Four: The Industrial College And The Experiment Station, Robert Crawford

These Fifty Years: A History of the College of Agriculture of the University of Nebraska

THE fifteen-year period from about 1875 to 1890 was marked by at least three important developments in the history of the College of Agriculture. One was the changing of the name of the Agricultural College to that of Industrial College and the consequent development of an engineering department within the Industrial College, as well as the reorganization of the work of the college. The second was the founding of the Agricultural Experiment Station with government funds supplied under the Hatch Act. The third important development was the erection of Nebraska Hall, a building to house the Industrial College, on the …

Scientific Discoveries Concerned With Pathogenic Micro-Organisms, Matilda Mary Steinbrecher

Bachelors’ Theses

Stand where you choose some calm night and look up into the great dome of the sky. Realize that those countless stars, once believed to regulate our destinies, have been proven by science to be other worlds more or less like ours. Let your thoughts wander on to objects near at hand. You see the rocks and soil and plants as did mankind for ages back; but where they not so long back saw nought else, you see rocks breaking into fertile soil and realize that minute living beings are responsible. You have come to understand that all the nitrogen …

How To Study The Western Birds, Grace Mccormac French

Jane Claire Dirks-Edmunds Documents

Originally a radio broadcast, this document explores the fraternal nature of bird watching. It was included in the papers of Dr. James A. Macnab, Dr. Jane Claire Dirks-Edmunds's mentor at Linfield College. The article mentions various books by bird-watching authorities and naturalists from around the Pacific Northwest.

Dirks-Edmunds, a 1937 graduate of Linfield, graduated from the University of Illinois in 1941; she returned to teach in the Biology department at Linfield from 1941-1974.

The Theory Of Spontaneous Generation, Arthur Thomas Kuesel

Bachelors’ Theses

The theories concerning the origin of life on this planet have been many and varied all down the ages. In the prescientific ages, if we may be allowed to designate those years as such, before science was as exacting and searching sit is now, practically all the theories advanced by the philosophers at the time have since been proven to be fallacies and all of them save one, the Theory of Spontaneous Generation have been discarded into the limbo of mistaken notions.

The Development Of The Seedling And The Tissues Of Pinus Monophylla, Irene Mary Keeley

Bachelors’ Theses

Considering plants as a whole, there are four principal divisions, the Tallophytes, the Bryophytes, the Pteridophytes and the Spermatophytes. The latter, or highest division of the plant kingdom, comprises two classes; the Angiosperms and the Cymnosperms, or seed-bearing plants. The Gymnosperms, of which there are four hundred living species, are the most widely distributed of any plants throughout the United States and tropical countries. We need not limit our knowledge to recent years for, Geologists tell us of their early discoveries of fossil representatives. This class is subdivided into different groups, the Coniferales being the most important and abundant. The …

The Compatibility Of Church And Science, John H. Casey

Bachelors’ Theses

The intellectual fashion, if such there be, obtained quite a few years ago to maintain that there was no such a thing as compatibility between religion and science. Like all fashions, it has passed out of vogue and the inherent and foolish fallacy behind it has been repeatedly an effectively exposed. However, it has exhibited another characteristic of all fashions by returning and finding favor in some quarters. Fortunately, its second inaugural is not so auspicious or general since the original style, while it caught the popular fancy, was too unmercifully denounced and derided to allow for a second successful …

Field Studies Of The Control Of The Sugar Beet Nematode. (1920-24). (Heterodera Schachtii Schmidt)., Alfred H. Bateman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The dire consequences of nematode invasion have been graphically depicted by Spiegler (1907), who says, the beet industry was at its heyday during the seventies. Nor satisfied with the land already in cultivation, the farmer plowed fertile lands along the border of the streams, wherein to grow beets, obtaining in some cases of 20 to 27 tons an acre.

A Contribution To Our Knowledge Of The Aphididae Of Utah, George Knowlton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are many groups of insects in Utah that have not been touched in a systematic way up to the present time, and to the knowledge of the author no systematic work has been done on the homopterous family Aphididae.

Due to the very common occurrence of the aphids, or plant lice, and the need for a simple key that would aid in the determination of these insects, this work was commenced in June 1923, continuous work being carried on in collecting, determining, drawing and describing, up to the present time.

Extreme Evolution Is Absurd And Moderate Evolution Is Not Yet Established, Marie Georgiana Blommer

Bachelors’ Theses

In the world of literature and science many records containing startling theories are to be found. Among these is the doctrine of Evolution. Many assure us that Science compels us to believe in Evolution. An explanation of the terms must be clearly understood to avoid a fallacious use of terms. Professor Huxley, who follows Hume, declares that Science is "nothing but trained and organized commonsense." The term is applied to physical science or "that whose province is the observation of phenomena and inferences directly deducible from them." The term "Evolution" is often differently understood. In its literal sense it is …

Critique Of Influence Of Mineral Manures Upon The Mineral And Nitrogen Composition Of Plants, Dan Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Variation in quality of plants of the same species has been known to exist for a long time. The influences bringing about such variation have been studied only comparatively recently. Quantity production has been given the greatest amount of attention as a rule, the beneficial results from the use of manures being judged by the quantity of produce. Some plants, however, varied so widely in composition, and the variations were of such paramount importance, that the influences affecting quality began to receive some attention. Of this type of plants may be mentioned sugar-beets and tobacco. There was also the hope …

Range And Pasture Management, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Sampson's range and pasture management is an excellent example of the application of the principles of ecology to the solution of economic problems. In grazing experiments it is of equal importance to know what is happening to the stock and to the vegetation. This emphasizes the fact, which ecologists are coming more and more to recognize, that animals, both wild and domesticated, have a proper place in the environment and that they play an important role in modifying the vegetational development. This volume consists largely of first-hand information obtained by the author during fifteen years of intensive pasture investigations for …

Direct Measurement Of Water Loss From Vegetation Without Disturbing The Normal Structure Of The Soil, J. E. Weaver, John Crist

Department of Agronomy and Horticulture: Faculty Publications

One of the most serious objections to the usual method of determining the water losses from plants is the almost universal use of containers which are quite too small to accommodate the normal development of the root system. But even where containers of sufficient size to overcome this obstacle are employed, the plants are grown in a mass of soil which has been at least fairly recently screened, mixed, aerated and watered and thus its structure is wholly unlike that which occurs in nature. This difference has been noticed for a number of years in connection with investigations of root …

Nursery Investigations With Special Reference To Damping-Off, J W. Toumey, T T. Li

Yale School of the Environment Bulletin Series

The object of this investigation is therefore fourfold: 1. To determine an effective means of control of damping-off in the School of Forestry Nursery. 2. To determine the effects of different soil sanitation agents on the germination and later growth of coniferous stock. 3. To determine the effects of different sanitation agents on the germination and growth of weeds. 4. To determine the effects of different sanitation agents on the physical characteristics of the soil.

Bulletin 119 - Take-All Of Wheat And Similar Diseases Of Cereals, W. M. Carne, J. G.C. Campbell

Bulletins 1 - 2999

This important disease, known also as Footrot, Blackleg, and Whiteheads, affects wheat principally, but also occurs on barley, rye, and certain grasses. In a very few instances it has been known to attack oats, but this is so rare that oats may be regarded for practical purposes as free from attack. Of the grasses attacked the most important, from a farming point of view in Western Australia, are Bailey Grass (Hordeum murinum), Silver Grass (Festuca bromoides and F. myuros), and the so-called Spear grasses (Bromus spp.). These annual grasses are very common in the wheat belt.

A Preliminary Report On The Nebraska State Museum, Erwin H. Barbour

Bulletin of the University of Nebraska State Museum (1924–2023)

The Nebraska State Museum has been established a sufficient number of years to make it widely known throughout the state, both by reputation and by personal visits. Incident to a growing clientele and an expanding correspondence, it is expedient that a concise circular letter be issued in bulletin form. Such a pamphlet can be promptly forwarded to inquirers and will offer obvious advantages over individual replies.

Root Behavior And Crop Yield Under Irrigation, Frank C. Jean, John E. Weaver

Papers of John E. Weaver (1884–1956)

More than half of the surface of the earth receives insufficient precipitation
for the most favorable growth of crops. The, best method of making up this deficiency is through the application of water by irrigation. Hence the economical use of irrigation water is one of the chief problems of agriculture in arid regions. Since much more land is available than can be irrigated by the supply of water, even when methods of greatest economy are employed, the welfare of these regions demands that the irrigation water be used as efficiently as possible (cf. Harris, 1916). It has been estimated that …

Trematodes From The Rat, Horace Wesley Stunkard, Chilson B. Haviland

Harold W. Manter Laboratory of Parasitology: Library Materials

Occasional examinations of rats for animal parasites have been carried on for over a hundred years. Later, knowledge of the importance of rats as reservoirs of infection and as agents in the transfer of parasitic diseases has led to the regular and careful examination of large numbers in various parts of the world. Among the more recent publications dealing with the parasites of rats may be mentioned Shipley (1908), Moll (1917), Chandler (1921), Balfour (1922), Baylis (1922), Stevenson (1922), Hegner (1923), and Lavier (1924). Notwithstanding the many investigations, only a single trematode parasite has previously been discovered and concerning it …

Control Of Flowering In Teosinte: Short-Day Treatment Brings Early Flowers, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

Attempts to force teosinte into flower in mid-summer, in order to facilitate hybridizing it with maize, have afforded considerable information concerning the flowering time of teosinte under diverse conditions. The possibility that some of this information may be of use to others suggests its publication. The paper is, therefore, to be considered as a help in the technique of teosinte and maize hybridization rather than a contribution ~to the solution of the physiological problems involved.

A Genetic View Of Sex Expression In The Flowering Plants, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

It seems a conservative statement to say that studies

of the past twenty years among animal forms have

tended increasingly to link the phenomena of sex inheritance

with the behavior of chromosomes. To this

result, cytology and genetics have contributed perhaps

almost equally. The number of forms in which

one sex is known to have a morphologically different

chromosome complex from the other sex are many.

That, with respect to the chromosomes, the female of

certain forms produces gametes of a single kind,

whereas the male produces two kinds, and that in

turn an egg fertilized by one kind of …

A Study Of The Environmental Conditions Influencing The Development Of Stem Rust In The Absence Of An Alternate Host. Ii. Infection Studies With Puccinia Graminis Tritici Form Iii And Form Ix, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Stakman and Levine have shown that Puccinia graminis tritici (Pers.) Erikss. and Henn. consists of a number of biologic forms, which can be determined by their action on different varieties of Triticum species. To date 37 such biologic forms have been identified by them through the parasitic action on 12 differential hosts chosen from a large number of varieties of Triticum species. To determine whether these biologic forms remain constant in their behavior under various environmental conditions, a detailed study of the host-parasite relation was undertaken with 2 of these forms. At the same time an opportunity was afforded to …

A Founder Of American Parasitology, Joseph Leidy, Henry Baldwin Ward

Harold W. Manter Laboratory of Parasitology: Library Materials

A biographical overview of American parasitologist Joseph Leidy and his work. bron September 9, 1823, Philadelphia, Pennsylvania, USA - died 1891.

Conclusion

A detailed study of his writing justifies the statement that no one has yet adequately presented or fully elucidated Leidy's contributions to helminthology and his writing will furnish rich lead to many future workers in this field. How monumental the task of preparing a record of the full life work of this extraordinary man who in the same breath as it were, in a single letter records discoveries of far reaching import on bacteria, amoebae, worms, and fossil …

Rammed Earth Walls For Buildings, U.S. Department Of Agriculture

Rammed Earth Collection (1923 - 1959)

Earth has been used for building dwellings from time immemorial. One method of use, superior to others, and which was known to the Romans has been preserved by tradition .t o modern times. This method consists of ramming slightly moist, specially selected earth, without the addition of straw or other material, between movable forms, and is known by itsFrench name, " pise de terre," which means "rammed earth." Pise de terre is a reliable building material when properly handled and is admirably adapted to structures on farms distant from transport routes. Little information has been published on rammed earth in …
