The Mandibular Tusks Of Amebelodon Fricki, Erwin H. Barbour
The Mandibular Tusks Of Amebelodon Fricki, Erwin H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
The ponderous mandible of the great shovel-tusked mastodon, Amebelodon fricki, was figured and described before it was practicable to remove the plaster cinches. In the meantime, this rare specimen has lain on its sand table awaiting the time when sections and casts could be made before mounting it permanently. A rare specimen, especially if heavy, unwieldy, and fragile, is rarely dismantled for study after it is mounted and installed in its case. A gelatine cast of the alveoli has been made, and through the assistance of Mr. Murray Jerome Roper, a cast of the left mandibular tusk has just been …

The Frequency Of Somatic Mutation In Variegated Pericarp Of Maize, R. A. Emerson
The Frequency Of Somatic Mutation In Variegated Pericarp Of Maize, R. A. Emerson
Department of Agronomy and Horticulture: Faculty Publications
Some years ago (Emerson 1922) the writer announced that in F2 of
certain crosses of variegated with colorless pericarp in maize the heterozygous
individuals changed to self color more frequently than did the homozygous
individuals of the same cultures. No “explanation” of this phenomenon
was then apparent, but later results, though still far from affording
an adequate solution of the problem, have furnished at least a working
hypothesis. The original unpublished paper, with minor modifications,
is given below, under the heading. “Somatic mutations in heterozygous
and in homozygous variegated pericarp.”

A Research Delusion, George L. Peltier
A Research Delusion, George L. Peltier
Department of Plant Pathology: Faculty Publications
With the administrative heads of many of our educational institutions demanding a doctorate of every member of the permanent staff, as it is supposed to be a prerogative for research, and the issuing of a list of titles published each year by their staff, the urge for so-called research, namely, a list of titles, goes madly on. In fact publication sometimes becomes a sort of self-defense, for the absence of any titles over a brief period of years stamps one either as lacking the ability of doing research or inefficient. Likewise, such a policy has permeated the staff, so that …
Wild Birds Introduced Or Transplanted In North America, John C. Phillips
Wild Birds Introduced Or Transplanted In North America, John C. Phillips
United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications
The early history of the introduction of foreign birds into this country is mostly clothed in darkness. The records of many attempts, if such there were, have long since been buried in back numbers of local newspapers, and if any experiment was unsuccessful it was soon forgotten. Hence, one trying to get an accurate idea of what has happened soon realizes that he is following a hopeless quest. It is much the same with the transplanting of native birds, especially game birds, which have been carried about all over the country from west to east and from east to west …
The Structure And Development Of Corallobothrium With Descriptions Of Two New Fish Tapeworms (With Five Plates), Hiram Eli Essex
The Structure And Development Of Corallobothrium With Descriptions Of Two New Fish Tapeworms (With Five Plates), Hiram Eli Essex
Harold W. Manter Laboratory of Parasitology: Faculty Publications
Introduction
Representatives of the genus Corallobothrium from American fish have never been described. Marshall and Gilbert (1905) report two members of this genus taken from Ameiurus melas (black bullhead) caught in the lakes at Madison, Wisconsin. La Rue (1914) refers to an undescribed species of Corallobothrium encysted in the livers of A. melas and A. nebulosus (common bullhead) from the Illinois River. Ward (1918) noted the presence of a species of Corallobothrium in lctalurus punctatus (channel-cat) at Milford, Nebraska. Aside from these incidental references, the American literature contains no information on this interesting group of fish tapeworms.

The Pine Tipmoth In The Nebraska National Forest, M. H. Swenk
Nebraska Agricultural Experiment Station: Historical Research Bulletins
On May 8, 1911, Mr. Smith Riley, the District Forester, with headquarters at Denver, in a letter to Acting Supervisor Pierce at Halsey, requested that the Nebraska Agricultural Experiment Station take up energetically the investigation of the pine tipmoth in the Nebraska National Forest. This request being presented to the Department by Mr. Pierce later in the month resulted in the presentation of the problem to the Experiment Station Council as a proposed Station project. The project was approved on May 31, 1911, and the expenses of the investigations of 1911 and 1912 that are reported upon in this bulletin …

Some Ecological Aspects Of Agriculture In The Prairie, J. E. Weaver
Some Ecological Aspects Of Agriculture In The Prairie, J. E. Weaver
Department of Agronomy and Horticulture: Faculty Publications
It is of more than passing interest that the cereal crops, namely: corn, spring and winter wheat, oats, barley, sorghum, and millet, have their center of greatest production in that portion of the United States originally covered by grassland. In fact, some are grown almost entirely in the grassland region, and other crops, as alfalfa and flax, which are similar in growth habits to wild legumes, wild flaxes, etc., growing among the grasses, also have their greatest acreage in grassland. Likewise, the largest areas of fruit production, including such tree fruits as apples, peaches, pears, and bush fruits as blackberries, …
The Differential Reaction Of Strains Within A Variety Of Wheat To Physiologic Forms Of Puccinia Graminis Tritici, T. A. Kiesselbach, George L. Peltier
The Differential Reaction Of Strains Within A Variety Of Wheat To Physiologic Forms Of Puccinia Graminis Tritici, T. A. Kiesselbach, George L. Peltier
Nebraska Agricultural Experiment Station: Historical Research Bulletins
Black stem rust of wheat (Puccinia graminis tritici (Pers.) Erikss. & Henn.), which occurs in Nebraska and thruout most of the wheat producing regions of the world, is of a composite nature, in that it consists of a number of physiologic forms which can be determined by their action on different varieties of Triticum species, as shown by Stakman and Levine. The ordinary commercial variety of wheat may likewise be regarded as a mixture, in that it consists of numerous strains, which differ in some more or less important characteristics, as has been frequently indicated in the literature concerning …

The Natural Vegetation Of Ohio. Iii. Plant Succession, Paul B. Sears
The Natural Vegetation Of Ohio. Iii. Plant Succession, Paul B. Sears
Papers in Ecology
In the preceding papers of this series (1) it has been shown that within the glaciated area the physiographic results of glaciation offer the best general key to the pattern of natural vegetation. The results of glaciation, in turn, have been largely influenced by preglacial conditions.
In analyzing the composition of the natural vegetation of Ohio certain groups of associations were distinguished, to wit, Prairie, Ash, Oak, and Beech. Each group includes several related classical associations as described by Cowles (2) and others.
The Natural Vegetation Of Ohio Ii. The Prairies, Paul B. Sears
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 …

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
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.

The Tapeworms Of The Rhinoceroses, A Study Based On Material From The Belgian Congo, Horace W. Stunkard
Harold W. Manter Laboratory of Parasitology: Library Materials
During the course of my study on the parasitic worms collected by the Lang-Chapin expedition of the American Museum to the Belgian Congo, I have had the good fortune to examine abundant material of Plagiotaenia gigantea (Peters). This interesting species, the first reported from the rhinoceros, has been confused with other cestodes from rhinoceros hosts, has been assigned to no less than three different genera in addition to the genus Taenia, to which it was originally referred, and has been the source of much discussion and difference of opinion during the past seventy years. A review of the literature …

The Natural Vegetation Of Ohio, Paul B. Sears
Papers in Ecology
This map has been prepared by transcribing the species of bearing trees recorded by the original surveyors who traversed the Territory and State of Ohio before the destruction of the virgin forest by the hands of white men.
Surveying of Ohio was begun in July, 1786, (1) under The Geographer of the United States, Thomas Hutchins, employing for the first time his device of sections one mile square. This empirical device was hailed as a great American invention, although the State of Ohio has since been found to possess a curved surface in common with the rest of the earth. …

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 …

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 …
