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 …

The Articulated Skeleton Of Titanotherium, Erwin H. Barbour
The Articulated Skeleton Of Titanotherium, Erwin H. Barbour
Bulletin of the University of Nebraska State Museum
The skeleton of a titanotherium, stored since 1894, was installed in the west corridor of Morrill Hall, April 28, 1931. In the meantime the specimen has been visited by many citizens, women's clubs, and especially by delegations of school children, boy scouts, and like organizations, from various parts of the State and elsewhere. Repeated requests for a popular report on this particular specimen actuates the writing of this leaflet. Titanotheres were by far the largest creatures of Oligocene time in Nebraska. In point of size they are called gigantic, elephantine, and titanic. The titans of Greek mythology were giants, and …

The American Mastodon With Mandibular Tusks, Erwin H. Barbour
The American Mastodon With Mandibular Tusks, Erwin H. Barbour
Bulletin of the University of Nebraska State Museum
Mastodons and mammoths, represented by their relics, are so frequently exposed by shovel, plow, road grader, dredge, and rains, that they have become household words. They are plainly the commonest and best-known vertebrate fossils. They were fortuitously entombed, and are now accidently found. Their relics, though numerous, never represent the grand total that lived. Indeed, it was a rare individual that fell where circumstances favored rapid interment and consequent preservation; the grand majority fell in the open where their bones suffered rapid and complete decay. The American mastodon occupies a position between the long-jawed, long-skulled, four-tusked ancestor called Palaeomastodon, and …

A Morning's Consignment Of Proboscidean Freight, Erwin Hinckley Barbour
A Morning's Consignment Of Proboscidean Freight, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum
In the accompanying cut the array of great tusks outlined through their rough crates may lack attractiveness, nevertheless the assemblage is quite out of the ordinary, and seems worth recording in bulletin form. In all museums, and like institutions, freight and express deliveries are matters of daily routine; however, the morning's freight shown in the cut is unique. Herein is represented the more showy portion of the proboscidean freight received at the Nebraska State Museum in a single consignment, in the field season of 1930. The other boxes of mammoth skulls, jaws, and bones, received at the same time, are …
On The Trigonometric Expansion Of Elliptic Functions, M. A. Basoco
On The Trigonometric Expansion Of Elliptic Functions, M. A. Basoco
Department of Mathematics: Faculty Publications
The problem of expressing an elliptic function in terms of infinite sums of trigonometric functions has been treated by Hermite, Briot and Bouquet, A. C. Dixon and others. In the present paper we treat the same problem from the point of view of Cauchy's residue theorem in function theory, which is also Briot and Bouquet's starting point, but we differ from these authors in that the integrand we use leads to an expansion for an elliptic function which is valid in an arbitrarily wide, but finite, strip of the complex plane, and which contains certain classical results as special cases. …

The Milford Mastodon, Mastodon Moodie I, Sp. Nov. A Preliminary Report, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum
In developing the hydro-electric plant of the Iowa and Nebraska Light and Power Company, a number of dams were thrown across the Blue River and its branches. One of these, known as Dam No.7, was built across the West Blue, about nine miles southwest of Milford, Seward county, Nebraska. This dam raised the water well above the ordinary river level, and flooded fifteen or twenty acres of valley land. The impounded water soaked into, and washed against, the base of a twenty-foot bank of cross-bedded sand, until some time during the winter of 1931, a portion of the bank near …
A New Amebelodont, Torynobelodon Barnumbrowni, Sp. Nov. A Preliminary Report, Erwin Hinckley Barbour
A New Amebelodont, Torynobelodon Barnumbrowni, Sp. Nov. A Preliminary Report, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum
The subfamily of longirostrine mastodonts known as the Amebelodontinae have been so recently discovered and described that as yet they; are little known by the citizens of this state. They are most briefly and directly described as shovel-tusked mastodons. The first one found, namely Amebelodon fricki, was secured in April 1927, and was published June 1927. In the meantime, many other examples of Amebelodonts have been added to the Morrill Palaeontological Collections of the Nebraska State Museum. The exact number cannot be stated until the material shipped in from the field during the current season is unpacked, cleaned, and identified. …
Evidence Of Dinosaurs In Nebraska, Erwin Hinckley Barbour
Evidence Of Dinosaurs In Nebraska, Erwin Hinckley Barbour
Bulletin of the University of Nebraska State Museum
Nebraska has long been a collecting ground famous for its fossil mammals, but as yet no dinosaurian bones have been reported, nor have they been expected. The distal end of a finely preserved femur, however, has recently been brought to light, supposedly occurring in position in the Dakota formation of eastern Nebraska. It was discovered, collected, and donated by Mr. J. B. White, (University of Nebraska, Law, class of 1899) on his farm two miles south of Decatur, in northeastern Burt County, near the Missouri River. It was found in undoubted Dakota sand associated with many leaf impressions. This is …
Parametric Solutions Of Certain Diophantine Equations, T. A. Pierce
Parametric Solutions Of Certain Diophantine Equations, T. A. Pierce
Department of Mathematics: Faculty Publications
In this note parametric solutions of certain diophantine equations are given. The method of obtaining the solutions is derived from an equation involving the determinants of certain matrices. It will be recognized that the method is a generalization of the method of Euler and Lagrange which depends on forms which repeat under multiplication. The matrices used in this paper must be such that their forms are retained under matric multiplication and addition. When integer values are assigned to the parameters of our solutions we obtain integer solutions of the particular equation under consideration; however not all integer solutions are necessarily …

EXPLANATION OF TEST REPORT: John Deere GP
TEST A: The manufacturer's representative operates the tractor for a minimum of 12 hours using light to heavy drawbar loads in each gear.
This serves as a period for limber up, general observation and adjustments. Adjustments that are permissible include valve tappet clearance, breaker ,point gap, spark plug gaps, clutch and others of a similar nature. No new parts or accessories can be installed without having mention made of it in the report. No data' are recorded during this preliminary run except the time that the engine is operated.
