Nebraska Tractor Tests
All tractors tested at the Nebraska Tractor Test Laboratory were certified by their manufacturers as being stock model machines, conforming to specifications filed with the application for test. No special or high-test fuels were used except as recommended by the manufacturer as necessary.
All results within the official tractor test report were actually attained in tests and are without correction or allowances for friction, temperature, altitude, etc. The results were initially accomplished with the tractor in charge of skilled operators employed by the University.
Unless otherwise noted, each tractor was apparently in good condition at the end of the testing …

Xx. The Term "Communal", Louise Pound
Department of English: Faculty Publications
I. The Doctrine of Communal Origins
The period following the French Revolution was deeply interested in "the people" as a mass conception, in all that belonged to them and all that they created. It was in this period that theorists on the origin of law, customs, religion, language, literature--particularly the folk-song and the folk-tale--liked to advocate the doctrine of spontaneous, unconscious growth "from the heart of the people," as the phrase went. Such conceptions of origin had their critics from the first; but they remained more or less orthodox throughout the nineteenth century, and they still have foothold in both …

Absorption Of Nutrients From Subsoil In Relation To Crop Yield, John W. Crist, J. E. Weaver
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 …
Direct Measurement Of Water Loss From Vegetation Without Disturbing The Normal Structure Of The Soil, J. E. Weaver, John Crist
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 …

The Hemotoxins Of Intestinal Parasites: A Critical Summary With Notes Of Some Cases, Joseph Mellick Leidy Ii
Harold W. Manter Laboratory of Parasitology: Library Materials
The mechanical and reflex disturbances produced by animal parasites in the intestinal canal and other organs of the body have long been recognized by pathologists and clinicians. The researches of economic parasitologists and the occasional reports by clinical observers indicate the presence of other factors deserving of further investigation. That certain parasitic worms secrete substances that effect the blood of their hosts deleteriously has been shown conclusively by the researches of Tallqvist, Schwartz, Schaumann and others. The broad tapeworm of man which is known to produce severe anaemia contains a hemolytic agent according to the experiments and researches of Schaumann …
Ice Cream Ingredients, H. P. Davis, B. Masurovsky, J. A. Luithly
Ice Cream Ingredients, H. P. Davis, B. Masurovsky, J. A. Luithly
Nebraska Agricultural Experiment Station: Historical Circulars
Ice cream is truly a frozen dairy product although other products than cream may enter into its make-up. The different ingredients that go into the ice cream mix exist in different qualities, grades, concentrations, and forms and it is desirable, therefore, for the ice cream maker to know something of them if a successful product is to be made.
A Study Of The Vegetation Of Northeastern Arizona, Herbert Christian Hanson
A Study Of The Vegetation Of Northeastern Arizona, Herbert Christian Hanson
University Studies (University of Nebraska) (1888–1984)
The State of Arizona is marked by a great series of cliffs that extend from the mouth of the Grand Canyon of the Colorado River in the northwestern part of the state southeastward into New Mexico. This line of cliffs, rising 1000 to 4000 feet above the desert plains forms the southwestern and southern boundary of the great physiographic province called the Colorado Plateaus. It is roughly circular and includes northeastern Arizona, northwestern New Mexico, western Colorado, and a large part of Utah. This province is subdivided by a number of deep canyons and high cliffs into numerous plateaus. The …

A Preliminary Report On The Nebraska State Museum, Erwin H. Barbour
Bulletin of the University of Nebraska State Museum (1924–2023)
The Nebraska State Museum has been established a sufficient number of years to make it widely known throughout the state, both by reputation and by personal visits. Incident to a growing clientele and an expanding correspondence, it is expedient that a concise circular letter be issued in bulletin form. Such a pamphlet can be promptly forwarded to inquirers and will offer obvious advantages over individual replies.
Root Behavior And Crop Yield Under Irrigation, Frank C. Jean, John E. Weaver
Root Behavior And Crop Yield Under Irrigation, Frank C. Jean, John E. Weaver
Papers of John E. Weaver (1884–1956)
More than half of the surface of the earth receives insufficient precipitation
for the most favorable growth of crops. The, best method of making up this deficiency is through the application of water by irrigation. Hence the economical use of irrigation water is one of the chief problems of agriculture in arid regions. Since much more land is available than can be irrigated by the supply of water, even when methods of greatest economy are employed, the welfare of these regions demands that the irrigation water be used as efficiently as possible (cf. Harris, 1916). It has been estimated that …

Size And Structure Of Leaves Of Cereals In Relation To Climate, William Edward Bruner, John E. Weaver
Size And Structure Of Leaves Of Cereals In Relation To Climate, William Edward Bruner, John E. Weaver
University Studies (University of Nebraska) (1888–1984)
Although a very large amount of work has been done on the variation in form, size, and anatomical structure of native plants grown under different conditions, relatively little attention has been given to similar studies of crop plants. As far as we are able to ascertain, no investigations have been made of variation in the leaves of cereal crops grown under widely different, measured environments.
During the past few years (1920-23), in connection with studies on the development and activities of the roots of crop plants (Weaver, Jean, and Crist, 1922), plant production as a measure of environment (Weaver, 1924), …
