Sand Fulgurites From Nebraska Their Structure And Formative Factors, Abram E. Anderson

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

So much has been written during the past century on the origin, structure and occurrence of fulgurites, or lightning tubes, found in many parts of the world that it would seem as though little remains to be added to the literature on the subject; but the discovery of a considerable number of unusually large and complete specimens in Holt and Stanton Counties, Nebraska, which exhibit remarkable definition of the particular features that have occasioned so much controversy regarding their formative processes, has added an important type to the representatives of this phenomenon and afforded clearer interpretation of the origin of …

Skeletal Parts Of The Columbian Mammoth Elephas Maibeni, Sp. Nov., Erwin Hinckley Barbour

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

The skeletal parts of Elephas columbi are said to be unknown, although teeth, jaws, and skulls are common enough. Columbi is a mammoth of southern adaptation, hence its parts are found from Nebraska southward. Elephas columbi occurs abundantly throughout the State and many examples are preserved in the Nebraska State Museum, as will be seen in an accompanying list.

Tetrabelodon Abell, Sp. Nov., Erwin Hinckley Barbour

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

Brown County, Nebraska, which has been so prolific of long-jawed mastodons, has yielded another form which seems to be new and which may throw light on certain small tusks that occur where Tetrabelodon bones abound. Heretofore, we have considered these to be embryonic, but they show apparent wear, and in other respects they are enigmatic, and at best, atypical. Tetrabelodon tusks proper, however young, are typical, and are obviously tusks in miniature. The tusks in doubt are of varying lengths and about the diameter of one's thumb, but taper backwards, are worn to a bluntly oblique point, and are slightly …

Hackberry Conglomerate A New Nebraska Rock, Erwin Hinckey Barbour

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

In the cabinets of the Nebraska State Museum are several excellent rock specimens, which at first sight pass for pisolite, which they simulate. Scrutiny shows that they are hackberry seeds in sand, cemented by lime and clay into a firm, compact rock. The term hackberry conglomerate seems apropos.

Notes On Nebraska Fulgurites, Erwin Hinckley Barbour

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

Some six or eight years ago the writer contemplated a study of Nebraska fulgurites, both in the field and in the laboratory. In the meantime however, it proves to be superfluous for, after supplying Mr. A. E. Anderson, of the American Museum of Natural History, with certain material and data he proceeded in a masterful way on a technical inquiry, and it is with pleasure that, although delayed in publication, his findings follow in Bulletin 7 of the Nebraska State Museum. The present paper will deal as briefly as possible with the mode of occurrence and gross structure.

Manganese Fulgurites, Harold J. Cook

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

During August, 1924, while doing reconnaisance work near the head of Chugwater Creek, Wyoming, on the ranch of Mr. J. L. Jordon, the writer's attention was called to some unusual and interesting specimens found in a limited area, perhaps an acre or so, on the slope of the small butte flanking the Chugwater Valley. The hills of the region are of Tertiary age, the particular spot under consideration being Oligocene, the Brule stage, or Oreodon beds.

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 One: The Federal Land Grant, Robert Crawford

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

THE FEDERAL LAND GRANT

THE modern-day agricultural college with its four-year collegiate course, its high schools and short courses, its well-developed scientific research, and its extension activities, has been a development of hardly more than the last quarter century. Certainly fifty years will cover the outstanding accomplishments. After the passage of the Morrill Land-Grant Act of 1862 it was many years before the agricultural or industrial colleges (as they were often called) began to lay the foundations of agricultural education and research as they are known today.

Because the prosperity of the New World hinged to a large extent on …

Chapter Two: The Founding Of The University, Robert Crawford

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

A HISTORY of the Agricultural College of Nebraska is also a history of the University of Nebraska. From the earliest years to the present day the two have been inseparably connected. The Agricultural College was established as one of the colleges of the University, later, in 1877, being incorporated in the Industrial College, and still later, in 1909, again becoming a separate college of the University, the College of Agriculture.

The University and Agricultural College received their endowment from two sources. The Enabling Act of 1864, providing for the state's admission into the Union, declared that seventy-two sections) (46,080 acres) …

Chapter Three: Establishment Of The Agricultural College, Robert Crawford

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

ESTABLISHMENT OF THE AGRICULTURAL COLLEGE

IT IS here that we draw the dividing line and proceed with the history of the Agricultural College rather than that of the University. Having seen the University established with its integral college units, it is now fitting to devote our attention primarily to the College of Agriculture, with only such references to the University as occasion demands.

It will be recalled that one of the primary purposes of the Land Grant Act of -1862 was to offer industrial education to the people, or as the Act stated, "to teach such branches of learning as …

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 …

Chapter Six: The Crowning Years, Robert Crawford

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

THE years from about 1909 to 1923 were the crowning years in the history of the College of Agriculture. Could Professor Thompson, the first professor of agriculture, and those early residents of the state! who wagged their heads at agricultural education have stepped into the farm campus in 1923, Professor Thompson would have found his most sanguine dreams more than realized, while those who scoffed perhaps would have remained to learn. They would have found nine great buildings devoted exclusively to experimentation and instruction, among them the finest agricultural engineering building in the world, a dairy building famous thruout the …

These Fifty Years: A History Of The College Of Agriculture Of The University Of Nebraska, R. P. Crawford

Nebraska Agricultural Experiment Station: Historical Circulars

It seems especially appropriate at this time to publish a history of the College of Agriculture of the University of Nebraska. The year 1922 marked the fiftieth anniversary of the formal establishment of the college by the Board of Regents, while the year 1924 marked the fiftieth anniversary of the enrollment of the first students in agricultural subjects. It is hoped and intended that this little volume shall preserve for the future much valuable material that would otherwise soon be forgotten.

Further Studies On The Effect Of Environment On Potato Degeneration Diseases, R. W. Goss, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The identification of potato degeneration diseases in the field is extremely difficult owing to the number of diseases now described, their manifestation on different varieties, the combination of several diseases on the same plant, and the further splitting up of these combinations into separate diseases. The influence of environmental factors in intensifying or inhibiting the symptoms of these diseases also increases the difficulty of diagnosis. In the present investigation the effect of environmental factors has been studied with the purpose of determining the limiting factor or factors in the masking of the symptoms, in the hopes of simplifying a complex …

An American Fossil Giraffe Giraffa Nebrascensis, Sp. Nov., W. D. Matthew, E. H. Barbour

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

A fragment of the lower jaw of a large fossil mammal with two well-worn teeth was dug up in June 1918, at a depth of 20 feet, while digging a cess pool at Bradshaw, York County, Nebraska.

The Chromosome Number Of Maize, T. A. Kiesselbach, N. F. Petersen

Department of Agronomy and Horticulture: Faculty Publications

The wide-spread interest in the genetics of maize, coupled with the uncertainty as to the number of chromosomes occurring in this species prompted the investigation which is here reported. From a review of the literature it appears that Kuwada (1911, 1915, 1919) is the only worker who has reported extensive counts of maize chromosomes. His results are summarized in table 1. Variations were reported in the number of chromosomes both within and between varieties as well as between different cells of individual plants. He concluded that sweet varieties are usually characterized by having twelve chromosomes, and starchy varieties by having …

The Occurrence Of Starch And Erythrodextrin In Maize And Their Segregation In The Pollen Of Hybrids, T. A. Kiesselbach, N. F. Petersen

Department of Agronomy and Horticulture: Faculty Publications

A variety of maize (Zea mays) differing from other known sorts in the texture of its endosperm was described by Collins (1909). The type of endosperm of this variety was designated as “waxy” in contrast with the starchy and sweet types of other maize. It has since been shown by Weatherwax (1922) that the carbohydrate of this waxy endosperm is erythrodextrin which can be distinguished from other carbohydrates by its red color reaction with iodine. It has recently been reported by Demerec (1924) and Brink and MacGillivray (1924) that this carbohydrate is also present in the pollen of …

Better Sires -- Better Stock: Build Better By Breeding, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Economy and logic indicate that the most satisfactory method of obtaining higher-yielding dairy cattle is to breed them. Nebraska raises the feeds - corn, oats and alfalfa - that will grow dairy cattle and can raise them as cheaply as any region. The method is simple. Use purebred dairy sires on the present cows. By the use of good purebred dairy sires great improvement can be obtained in a single generation.

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 …

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 …

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 …

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.

Absorption Of Nutrients From Subsoil In Relation To Crop Yield, John W. Crist, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Investigations of the development of root systems of native and crop plants have been pursued for a number of years at the University of Nebraska. The gradual intensification of this work has led to a type of experimentation designed to discover the nature of the activities of roots at great depths in relation to absorption of water and nutrients. In the present investigation the effects of absorption of nutrients from deep levels upon quantity and quality of yield were determined. Studies on the amounts of water and nitrates removed by crops from various soil levels were begun in i919, but …

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 …

Effect Of Environment On Potato Degeneration Diseases, R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

During recent years much of the investigational work on the degeneration diseases of the potato has been directed toward the separation and identification of a number of diseases formerly grouped under the general names of mosaic, leaf roll, and "running out". Extensive studies have also been made on methods of transmission, host range, overwintering and the identification of the evasive causal factor. Investigations of this type, however, have progressed slowly because of the necessity of developing new methods of research, because of the complexity of the problem, and because of the lack of knowledge regarding the causal factors. Meanwhile there …
