The Preparation Of Laboratory Specimens As An Aid To The Diagnosis Of Animal Diseases, L. Van Es, L. V. Skidmore

Nebraska Agricultural Experiment Station: Historical Circulars

Many problems in connection with animal diseases require for their solution the application of methods which can only be undertaken in properly equipped laboratories. This ordinarily involves the collection, packing, and shipping of samples of specimens. The manner in which this is done is a most important factor and to a very large extent is responsible either for the success or for the failure of the undertaking. The discussion of the subject to which the following pages are devoted is taken in hand in the hope that it may provide guidance to the veterinarians and others who may have occasion …

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 …

The Spindle-Tuber Disease As A Factor In Seed Potato Production, H. O. Werner

Nebraska Agricultural Experiment Station: Historical Research Bulletins

The lines of experimentation that supplied the data herein reported, stated in very general terms, were as follows: (1) Tuber-line selection studies (2) Relation of environmental conditions to seed-potato production (3) Seed-potato strain trials of certified and uncertified stock (4) Spindle-tuber transmission experiments. Most of these general lines of experimentation will not be completely discussed as a unit in any one part of the bulletin. For the sake of clarity, consecutive thought, and elimination of repetition, data will be selected from any experiment for insertion and discussion under the most logical heading in any part of the bulletin. Unless otherwise …

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.

Ec26-129 Profitable Wheawt Production, P.H. Stewart, D.L. Gross

University of Nebraska-Lincoln Extension: Historical Materials

More profitable wheat production, rather than greater total production in Nebraska, is the object of this circular. The grower who has the largest acreage of wheat does not necessarily make the greatest profit. High yields per acre usually means a lower cost and a great profit per bushel. Wheat of high quality brings additional profits. High yield and quality are usually the combined result of good seed, disease prevention, crop rotations, a well-prepared seed bed, the proper time of seeding, and reasonable care in harvesting, threshing and storing.

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 …

A Study Of The Environmental Conditions Influencing The Development Of Stem Rust In The Absence Of An Alternate Host. Iv. Overwintering Of Urediniospores Of Puccinia Graminis Tritici. V. The Period Of Initial Infection Of Urediniospores Of Puccinia Graminis Tritici On Wheat. Vi. Influence Of Light On Infection And Subsequent Development Of Urediniospores Of Puccinia Graminis Tritici On Wheat, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

IV. In order to ascertain whether the urediniospores of Puccinia graminis tritici (Pers.) Erikss. and Henn. overwinter under the environmental conditions prevailing at Lincoln, Nebraska, a series of experiments was carried out extending over a period of 5 years. The results of this investigation are briefly presented. V. By the period of initial infection is meant the time required by a pathogen after it reaches a susceptible plant part to enter the tissues. To determine what the period of initial infection of urediniospores of Puccinia graminis tritici might be, experiments were undertaken during the season of 1923-24 using urediniospores of …

Winter Wheat Investigations, T. A. Kiesselbach

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Twenty years of wheat breeding, consisting chiefly of the isolation and testing of pure lines, has now been conducted at the Nebraska Agricultural Experiment Station. It is the purpose of this paper to report the conduct and results of this work. The resulting strains are compared with the best other wheats available from Nebraska and other sources. The effects of a number of cultural practices related to the preparation of seed, seeding, treatment of the growing crop, and harvesting are also presented. Some consideration is given to the experimental technique of the comparative tests.

Better Rations - More Eggs, F. E. Mussehl

Nebraska Agricultural Experiment Station: Historical Circulars

Well-bred and well-fed hens are conceded to be economical producers of a very wholesome food product, eggs, but our hens are not miracle workers and they insist on the right kind of raw material for building the egg. Nebraska poultry growers fortunately have all the natural feeds - corn, wheat, oats, barley, and dairy and packing house by-products - readily available at lower cash prices than prevail in most other states, and so our special problem is that of combining them so that eggs may be produced at the lowest cost per dozen.

A Study Of The Environmental Conditions Influencing The Development Of Stem Rust In The Absence Of An Alternate Host. Iii. Further Studies Of The Viability Of Urediniospores Of Puccinia Graminis Tritici, George L. Peltier

Nebraska Agricultural Experiment Station: Historical Research Bulletins

1. The influence of relative humidity and temperature on the viability of the urediniospores of two Physiologic Forms of Puccinia graminis tritici has been determined. 2. The same general relation between the viability of the urediniospores and the relative humidity and temperature was found, namely, that the lower the temperature the longer the spores retained their viability at all relative humidities, while at any stated temperature the spores were viable the longest at the medium humidities. 3. Urediniospores of Physiologic Form XXI held at 49.0 per cent relative humidity and maintained at a temperature of 5° C. when tested for …

Investigations On The Root Habits Of Plants, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Ten years ago, while studying the vegetation of semi-arid eastern Washington, interest in root studies was aroused because of the extensive root systems of the native species. Balsamorrhiza sagittata, the first plant excavated, is representative. The strong tap root reaches a depth of six feet, and very numerous branches run laterally to distances of about two feet. Further investigations in several other states showed that extensive root systems are the rule among grassland species. Andropogon haliji, with exceedingly well branched fibrous roots seven feet deep, is representative of many of the dominants. About ninety percent of the more …

Transect Method Of Studying Woodland Vegetation Along Streams, J. E. Weaver, Herbert Hanson, John Aikman

Department of Agronomy and Horticulture: Faculty Publications

In pursuance of an investigation of competition among certain shrubs (Rhus glabra, Corylus americana, Symphoricarpos spp.), and between these shrubs and Quercus macrocarpa, it became imperative, for a proper understanding of their behavior, to ascertain just how near the edge of their range they were growing. The station, which is located at Weeping Water, Nebraska, is on the Weeping Water River, a branch of the Missouri, I5 miles west of its mouth. This stream arises I 5 miles farther west, and in general its course parallels that of the Platte River about I 5 miles north. As is …

Some Marine Fish Trematodes Of Maine, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

During the summer of 1924 a study of marine fish parasites was made at the Mount Desert Island (Maine, USA) Biological Laboratory. The present paper represents a preliminary report on the trematode group. Three new species of trematodes are described. Only brief consideration is here given to species already known. A later paper will deal more completely with these and related forms.

Includes brief descriptions of Podocotyle atomon (Rud. 1802), Podocotyle olssoni Odhner 1905, Stephanochasmus baccatus Nicoll 1907, Lepidapedon rachion (Cobb.) 1858, Lepidapedon elongatum (Lebour 1908), Homalometron pallidum Staff. 1904, Steganoderma formosum Staff. 1904, Otodistomum cestoides (van Ben. 1870), Hemiurus …

Hardy Alfalfa For Nebraska, T. A. Kiesselbach, A. Anderson

Nebraska Agricultural Experiment Station: Historical Circulars

Comparative tests of varieties and regional strains of common alfalfa at the Nebraska Experiment Station have clearly indicated that winter hardiness is an important factor to be considered when purchasing alfalfa seed. Much of the seed sold in the United States has proved inferior in this regard for Nebraska conditions. The use of southern-grown domestic seed or seed imported from countries with a much milder climate than that of Nebraska should be avoided in this state. On the other hand, reliance may be placed on the seed of hardy varieties or hardy regional strains of common alfalfa grown in Nebraska …

Selection, Breeding, Methods Means More Milk, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Milk good cows. It pays if you know how. Good dairy cows will always make money. Scrub, poor, or common cows never bring a good profit and usually cause a loss. Why waste feed and labor on inefficient producers, the kind that never make a satisfactory profit? Join a cow testing association. Let the tester keep books on your cows and let the milk scale and the milk sheet point out the money makers. Improvement comes only from selection and breeding.

Feeding The Dairy Cow, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Circulars

Cows produce milk from feed and water only. Therefore feed in proper quantity and quality is usually the limiting factor governing a cow's production up to the limit of her capacity.

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 Chinch Bug And Its Control, M. H. Swenk

Nebraska Agricultural Experiment Station: Historical Circulars

During the last half century there have been five separated and well-marked chinch bug outbreaks, or periods of serious damage, in Nebraska, and we are now approaching the climax of a sixth such period. As to just how serious this present outbreak will be in 1925 no one can now say, because no one can exactly forecast the weather conditions of the summer, but the present situation is sufficiently menacing to make advisable the issuing of this circular, which aims to give the essential information concerning the chinch bug as a Nebraska pest, and the locally applicable means of control.

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 …

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 …

Tuberculosis Of Swine, L. Van Es

Nebraska Agricultural Experiment Station: Historical Circulars

The tuberculosis of swine constitutes a definite and very interesting section of the general problem of the tuberculoses of warm-blooded animals. No one section of this general tuberculosis problem can be adequately solved without regard to all the other sections into which it may be divided. The disease in swine is perhaps the most outstanding example which illustrates this point. This animal, extremely susceptible to tuberculous disease, but without a type of infection specifically its own, derives its infection by contact with any of the types of tuberculosis of warm-blooded animals.

Ec25-228 Farm Slaughter Of Hogs, Wm. J. Loeffel

University of Nebraska-Lincoln Extension: Historical Materials

Slaughtering hogs and curing the meat on the farm is a common practice which makes available a palatable and nutritious food. It utilizes labor at a season of the year when usually there is no great rush of work.

As a general rule, farm slaughter is not to be recommended until cold weather is a certainty, for warm weather is apt to cause heavy spoilage. Meat is a highly perishable food product, therefore absolute cleanliness should prevail in its handling. Contamination of meat by soiled hands, clothing, tools, or containers is not only insanitary but actually lowers the keeping quality …

Rb25-207 The Spindle-Tuber Disease: One Cause Of "Run-Out" Seed Potatoes, H.O. Werner

University of Nebraska-Lincoln Extension: Historical Materials

The spindle-tuber disease is one of the most prevalent potato diseases occurring in all parts of Nebraska. It has been found in all varieties tested. It does much damage to the potato crop, in that it reduces the yield and injures the market quality of the potatoes.

This 1925 publication discusses the spindler-tuber disease also known as "running-out" or degeneracy of seed potatoes; the distribution of the disease; effect upon yield and quality; symptoms of the different potato varieties; transmission of the disease and experiments; rate of increase of the disease; dry land versus irrigation in western Nebraska; straw mulching …

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 …

Front Matter: These Fifty Years, Robert Crawford

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

PREFACE

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.

To study back over fifty years of Nebraska education and agriculture and to choose the facts that should …
