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 …

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.
