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 …

Bulletin No. 189 - Ridding The Land Of Wild Morning Glory, George Stewart, D. W. Pittman

UAES Bulletins

"Morning glory" is the common name for one of the worst weeds found in Utah. On account of its general resemblance to a cultivated plant spoken of as morning glory, the weed is frequently and more correctly known as the "wild morning glory." Since everyone who handles farm land knows the plant, a description of it is unnecessary. It may not be amiss, however, to mention that the name probably comes from the fact that the showy, funnel-shaped flowers are open only in the morning, being folded within the sepals after midday or earlier in hot, dry weather.

Bulletin No. 190 - Corn Silage In A Dairy Ration, W. E. Carroll

UAES Bulletins

In 1914 a study of the value of corn silage in the dairy ration was undertaken at this station. The first phase of the general question to receive attention was the effect of adding silage to a basal ration of alfalfa hay and grain.

Circular No. 52 - Rules And Regulations For The Utah Intermountain Egg-Laying Contest, Byron Alder

UAES Circulars

The contest will be located on a part of the Utah Agricultural College Farm near the experimental poultry yards. It will be managed by the Poultry Department with an experienced poultry raiser in direct charge of the feeding and care of the hens in the contest. It is hoped that the entry fee and the sale of eggs will pay for the expense of the contest. The buildings, ground, and fences will be built and furnished by the college.

Suggestions On The Incorporation Of Cooperative Livestock Shipping Associations Under The Laws Of South Dakota, M. R. Benedict, Turner Wright

SDSU Extension Circulars

The cooperative shipping of livestock form South Dakota points has become so general that nearly every farm is familiar with the workings of the Cooperative Shipping Association. During the early stages of this movement; that is, up to the present time, these organizations have been for the most part loosely formed, unincorporated associations of producers with no very permanent existence. Where they were well managed, they have accomplished fairly well the principal purposes of a livestock shipping association; namely, the narrowing of the handling margin at the local points, better grading of the stock shipped, and the elimination of excessive …

Western Yellow Pine Mistletoe, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

This bulletin gives the results of studies over a period of twelve years on the effect of mistletoe Razounzofskya cryptopoda (Engelm.) Cov. on the growth and seed production of western yellow pine. The intensive part of these studies was carried on near the San Francisco mountains in northern Arizona. " The parasite is the most widely distributed and one of the most serious enemies of the western yellow pine." On southern slopes and near the lower limit of the distribution of the pine, areas occur where 75 to 90 per cent of all trees above six inches in diameter are …

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.

Control Equipment For The Study Of The Relation Of Environment To Disease, George L. Peltier, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The investigation of certain plant disease problems in Nebraska has necessitated the study of the relation of various environmental factors to these diseases. The control of these environmental factors in the greenhouse studies has been obtained by the use of previously described apparatus or their modification and adaptation, along with new methods which have been devised to meet the needs of these investigations. In view of the widespread interest in the subject of environmental control for experimental studies, it was deemed advisable to present briefly the methods now in use in this department in the hope that the information may …

Bulletin No. 188 - Maintaining The Productivity Of Irrigated Land, D. W. Pittman

UAES Bulletins

It is almost universal history that in farming a newly developed region no attention whatever is paid to maintaining the fertility of the soil. This is natural for two very obvious reasons. In the first place the pioneer has other and more pressing problems in the "subduing" of the new land, and in the second place such virgin soils are generally blessed with a great abundance of native fertility. New lands in an arid or semiarid region are usually especially fertile because they represent a long-time accumulation of fertility which is not possible under humid conditions. Since in a humid …

Potato Wilt And Stem-End Rot Caused By Fusarium Eumartii, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The present study was undertaken to obtain more information regarding the pathogenicity of Fusarium eumartii and to compare its action with F. oxysporum, in order to distinguish between and to determine the relative importance of the diseases produced by these two organisms. An effort was also made to explain the many negative results of isolation studies reported by various investigators, as well as the inconsistent results often reported in studies of the transmission of wilt by infected tubers. Investigations dealing with the effect of certain environmental conditions on the occurrence of the disease were also undertaken. All of the …

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 …

Circular No. 51 - Foot-And-Mouth Disease, H. J. Frederick

UAES Circulars

The following is printed that the seriousness of the foot-and-mouth disease outbreak might be apparent to the farmers and ranchmen of Utah, that the importance of the quarantine regulations might be emphasized, that precautionary methods might be adopted by each individual concerned, that the disease might be recognized should it occur, and that each stock man of the state might see the importance of immediately reporting to the State Veterinarian or to a veterinarian in his locality or to the Utah Agricultural Experiment Station.

A Study Of The Effect Of The Age Of Parents On The Ability Of Dairy Cows To Produce Milk And Butterfat, J. Howard Maughan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The question of the possible effect of the age of parents on the quality of the offspring which they produce has long been a disputed one. It is held by some that the ages of both parents act together in determining the quality of offspring. There are others who maintain that the age of the dam only is a factor and still others who believe that only the age of the sire need be considered in this connection.

Loss Of Minerals In Cooking Vegetables, Sadie O. Morris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It has long been recognized that vegetables contain certain necessary substances which are essential to the human diet. Considerable attention has been given the different foods as to their economic value to human nutrition, however the information concerning the preparation of foods as to their nutritive losses is as yet inadequate. Considerable research work has been done in certain directions and some valuable data accumulated as to the economic losses contained in the waste or discarded portions of the food material. Several investigators have rather accurately determined not only the economic, but also the nutritive losses, especially those which occur …

The Effect Of Dry Heating On Alfalfa Seed And Adulterants, Ernest V. Staker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The relationship of artificial heating to the germination of seeds has been a subject of more or less interest for the last 75 years. Like other research work, experimenters first had their attention called to the problem largely as the result of innate curiosity. They were interested in the result as measured by germinative power, of the application to seeds of different amounts of heat for varying periods of time, consequently many divergent and sundry experiments were carried out. Seeds of a large number of plants have been subjected to tests and the results recorded. The investigations include the effect …

Qualitative Mendelian Inheritance In Wheat Hybrids, Aaron F. Bracken

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two methods of crop improvement are open to the plant breeder. Pure-line selection, which might be mentioned first, deals with the natural variability in plant populations. Thru selection, isolation, and comparative yield tests superior individuals are located. Nothing, however, can be added which the plant does not already have. Here hybridization provides a new starting point. Increased variation, new combination of characters, and thus greater opportunities are provided for improvement. The present investigation has for its purpose a study of the latter phase of this subject.

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.

Normal Spread Between Local And Terminal Market Prices For Sheep, Von T. Ellsworth

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The consuming world must look to eight nations for 68 per cent of its supply of sheep and sheep products, as shown by the accompanying chart and table No. 1. Australia leads other nations with 19 per cent, while the United states follows with 8. 7 per cent of the world's sheep population. The nature of the industry confines it to the more sparsely populated regions, and areas ranking high in cheap grazing lands.

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 Study Of Size Inheritance In Wheat, Peter Nelson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The results presented in this paper are from data accumulated by a study of the F3 generation of a cross between the two varieties, Sevier and New Zealand wheat. This cross was made during the summer of 1920 by Professor George Stewart with the object of combining the high-yielding power of Sevier with the strong straw of New Zealand. In the fall of 1922 the problem was assigned to me, at which time I selected about 150 superior plants, possessing the desired characteristics, at least so far as appearance was concerned. Since then these plants and the F3 generation have …

Inheritance Of Chaff Color, Head Shape, And Grain Texture In Wheat, Delmar C. Tingey

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The data presented in this thesis are the results obtained from a study of the F₂ and F₃ generations from a cross between the wheat varieties, Dicklow and Hard Federation. Toward the end of the summer of 1922 this problem was assigned to me by Professor George Stewart. The plants then growing in the field were in the F₂ generation, the cross having been made in 1920 by Professor Stewart. The chief purpose of the cross was to improve the grain quality of spring-irrigated wheat by the application of Mendelian principles in such a way as to …

Inheritance Studies In Kanred X Martin And In G-149 X Ridit, Myron T. Hansen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The studies here reported involve two crosses, one of which was between a pure line of Kanred and a pure line of Martin from a bunt resistant selection. The other was between a pure line of G-149, a rust-resistant segregate from Sevier x Dicklow, and a pure line of Ridit. These were both economic breeding projects made in an effort to combine the good commercial qualities of Kanred and G-149 with the high bunt resistance of Martin and Ridit, respectively.

These crosses also furnished, as a by-product, some good genetic data, as in each cross one parent was fully awned …

Hog Houses For Nebraska, O. W. Sjogren, I. D. Wood

Nebraska Agricultural Experiment Station: Historical Circulars

The material contained in this bulletin is a culmination of several years' study and investigation of the different types of hog houses used in Nebraska. It is realized that the plans given will not suit all conditions that may arise, but an effort has been made to bring out the essential factors so that the plans may serve as a guide in planning a house suited to particular conditions.

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 …
