Bulletin No. 198 - Report Of The Director: For The 18-Month Period From January 1, 1925, To June 30, 1926

UAES Bulletins

In the following report of the Utah Agricultural Experiment Station for the past eighteen months, record has been made in as much detail as space would permit. The text is intended to give the present status of the projects under consideration and to record the changes and additions since the last report.

The Immediate Effect Of Gametic Relationship And Of Parental Type Upon The Kernel Weight Of Corn, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

This investigation to determine the relation of the kernel weight of corn to the source of pollen with which it was fertilized has been made to answer several questions of both practical and technical interest: (1) To what extent is kernel weight affected in the current crop by the "breadth of breeding" or the gametic relationship? (2) What is the relation of the diversity of parental type to the immediate effect of foreign pollen upon the kernel weight of corn? (3) Is the immediate effect of cross-fertilization upon the kernel weight of sufficient importance to justify the annual mixing of …

Alfalfa Investigations, T. A. Kiesselbach, Arthur Anderson

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The purpose of these alfalfa investigations has been to determine the relation of variety, source of seed, and cultural practice to the yield and quality of hay produced. Due to the high initial cost of seeding, the inconvenience and wastefulness of losing a stand prematurely, and the superiority of properly-made hay, an understanding of these relationships is very important.

The Segregation Of Carbohydrates In Crosses Between Waxy And Starchy Types Of Maize, T. A. Kiesselbach, N. F. Petersen

Department of Agronomy and Horticulture: Faculty Publications

The purpose of this paper is to report the Mendelian segregation of waxy and starchy carbohydrates in both the sporophytic and gametophytic generations of maize. This is of especial genetic interest because the counts of segregate waxy kernels have very commonly been short of the expected numbers, although this character appears to be a simple Mendelian recessive. Collins (1909) was the first to point out the physical difference in the endosperm of waxy and ordinary starchy varieties.

While the exact difference in their chemical nature has not been established, Weatherwax (1922) considered that the waxy carbohydrate was erythrodextrin because of …

Turkey Production, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Whatever problems turkey production presents, lack of demand for roast turkey is not at this time one of them. Turkeys rate so high in popular esteem that very rarely indeed do prices fall below that of dressed chickens and usually the best grades are 12 to 15 cents per pound higher during the holiday season. The world of commerce has become quite complex but the consuming public still has one clear way of speaking to producers. In the language of the dollar we are apparently being asked to raise more turkeys.

Bulletin No. 195 - Field Studies Of Sugar-Beet Nematode, George Stewart, A. H. Bateman

UAES Bulletins

The sugar-beet nematode has now become of importance in Utah. It occurs in spots in practically all of the older beet-growing districts and in a few parts of the state in much larger areas. The intensity of infestation varies from mere traces to nearly complete occupation. One of the areas of severe infestation in Utah on a large area is in the Lewiston district, of northern Cache Valley. The survey here reported was undertaken in order to find the extent of nematode infestation in Cache Valley and the possibility of its control by ordinary cultural practices.

The Natural Vegetation Of Ohio Ii. The Prairies, Paul B. Sears

Papers in Ecology

It is well known that many treeless areas existed in Ohio before white settlement. These areas, of various ecological character and usually restricted in size, were in a few cases fairly extensive—embracing from fifty to one hundred square miles. The term "prairie" was rather generally applied to them, although more exact terms were not wanting. Like the various forest associations, these treeless areas have played an important role in influencing industrial and cultural phases of human life in Ohio (1). The present paper is an attempt to reconstruct such areas, now destroyed or obscured by secondary successions induced by white …

Correlation Studies In Wheat, Joseph Reed

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Considerable work has been done by plant breeders and investigators in the study of individual plant characters, but only a few have attempted to work out correlations between characters in crop plants. One reason for this seems to be, that many investigators have felt that correlation studies were of very little practical value. This attitude was due perhaps to the interpretation given correlation data, especially the nature of the casual agency or agencies to which the correlation was attributed. Most of our plant breeders however, have been too busy working on experiments with single characters and have given little or …

Distribution And Structure Of The Forests Of Eastern Nebraska, John M. Aikman

University Studies (University of Nebraska) (1888–1984)

This paper is a study of the distribution and structure of the forests of extreme eastern Nebraska. The Missouri river, which forms the eastern boundary of the state, has so greatly modified the climate, that along its course an arm of the deciduous forest extends far into the grassland. Most of the trees and shrubs composing this forest are at the extreme western limit of their range. The range, grouping, and behavior of the several dominants and subdominants, under the environmental conditions imposed upon them, and the transition of forest to grassland are the subjects of this investigation. This region …

Directory Of Certain Alumni The Department Of Geology And Geography The University Of Nebraska, E. F. Schramm

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

In the Department of Geology and Geography, The University of Nebraska, there have been over 10,000 registrants between the years 1891 and 1926. So many inquiries have been received concerning alumni and their addresses that it seems advisable to publish this directory. The list is necessarily incomplete since many of the alumni have not informed the Department respecting their addresses and change of positions. Out of the total number of those who have pursued professional vocations the following have kept in close touch with the Department.

Archidiskodon Maibeni, Erwin H. Barbour

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

Archidiskodon maibeni was first described in Bulletin 10 of the Nebraska State Museum under the title" Skeletal Parts of the Columbian Mammoth, Elephas Maibeni." * Dr. Henry Fairfield Osborn finds it expedient to found a new genus, Archidiskodon, to include the earlier and more primitive mammoths. Hence the change in the generic name. t'Mammoths and modern elephants have long been grouped together under 'the genus Elephas. Subdividing the genus does not necessarily do away with this convenient and rather familiar old arrangement.

Factors Determining Natural Reproduction Of Longleaf Pine On Cut-Over Lands In Lasalle Parish, Louisiana, Herman H. Chapman

Yale School of the Environment Bulletin Series

The original ' pine forests, of the southern states covered from 125 to 130 million acres of land, about two-thirds of which was Longleaf pine. Four-fifths of this area had been cut over by 1920, leaving about 230 million acres, one-half of which is Longleaf pine. Of the cut-over lands, 31 million acres have not restocked. The Longleaf pine has thus been the principal tree crop on about 85 million acres of land, of which 11% million acres remained' in 1920, giving a cut-over area of nearly 73 million acres, or 114,062 square miles. This area is nearly half the …

An Ecological Study Of Timpanogos Creek From Aspen Grove To Wildwood, Marion L. Harris

Theses and Dissertations

Ecology may be oonsidered as one of the vital parts of botany, since there are two ultimate facts in this science; namely, the plant and its habitat . The habitat is made up of the physical factors that control function. At Timpanogos there are so many different habitats, that the chief problem is not that of finding a problem to study, but rather that of selecting one from the many. The purpose of this paper is to point out some of the interesting features that are found in a study of Timpanogos Creek from Aspen Grove to Wildwood.

Dairy Calf Care And Management, H. P. Davis, R. F. Morgan

Nebraska Agricultural Experiment Station: Historical Circulars

Calf raising begins before the calf is born. A cow that is healthy and in good physical condition will, in all probability, drop a strong, vigorous calf. The feeding and care of the cow before calving is therefore of the greatest importance for the future development of the calf.

The Effect Of Hydrogen Ion Concentration Of Solution Upon The Absorption Of Water By The Hard Seed Of Alfalfa, A. L. Starr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The hard seed coat found on some seeds has long been an object of interest to experimentors in seed germination and a great deal of work has been done on various phases of the problem. Some have attacked it with the idea of hastening germination, while others have been interested in determining the nature of the seed coat and isolating the factors which make it impermeable under ordinary favorable germination conditions.

Figure 1 shows the location of the project with respect to Salt Lake, Ogden, Brigham City, Logan, and Cache County. Cache County, with a population in 1920 of 27,000 people, is located in the north-central part of the state and occupies the greater part of the fertile Cache Valley. Cache County Water Conservation District No.1 includes 8490.78 acres (of which 7373.38 acres are allotted water) and extends from Bear River and its …

An American Fossil Giraffe, 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. This unique specimen, accessioned 7-7-18, was brought to the Nebraska State Museum by A. Archie Dorsey, and was donated by C. B. Palmet, both of Bradshaw. It undoubtedly occurred in loess, which is thickly as well. as extensively developed in this region. It is a ruminant jaw, the teeth preserved being P4 and m1. The characteristic pattern of the premolar excludes reference to …

Prosthennops Xiphodonticus, Sp. Nov.: A New Fossil Peccary From Nebraska, Erwin H. Barbour

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

During the field season of 1915, while collecting, a mile or two west of Valentine, Cherry County, Nebraska, Messrs. A. C. Whitford and J. B. Burnett secured for the Morrill-Maiben Palaeontological Collections, The Nebraska State Museum, The University of Nebraska, a finely preserved jaw of a small fossil hog, or peccary, belonging to the genus Frosthennops, accessioned No. 85-11-8-15B. & W.

The mandible under consideration was preserved in fine sand and is without blemish save that the condyle and coronoid are wanting. The dentition is perfect. In allusion to the sword-like tusks, which are unduly large, the species name xiphodonticus …

Bulletin No. 192 - Biennial Report Of The Director: For The Years 1923 And 1924

UAES Bulletins

No report (either annual or biennial) of the work of the Utah Agricultural Experiment Station has been published separately since 1906. There has been so much inquiry regarding the present status of research projects that a brief report at this time is considered opportune. The report is an attempt to give the reader a brief but concise and comprehensive survey of the research work now under way at the Utah Agricultural Experiment Station as well as a brief description of the work being attempted on each of the experimental farms.

Chapter Five: Agriculture Comes Into Its Own, Robert Crawford

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

IT MAY be said that it took eighteen years to lay the foundation of agricultural instruction and research in Nebraska, and another eighteen years to build on this foundation. The eighteen years beginning about 1890 marked a period of great development for the Industrial College as well as the University itself. A School of Agriculture was early established and in a comparatively few years began to number its students in the hundreds. What the agricultural department of the Industrial College had heretofore lacked in numbers, this secondary school supplied. For the first time, the college farm began to be regarded …

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.

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 …

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.
