An Analysis Of Fishing In The Tva Impoundments During 1939, R. William Eschmeyer, Clarence M. Tarzwell
An Analysis Of Fishing In The Tva Impoundments During 1939, R. William Eschmeyer, Clarence M. Tarzwell
United States Environmental Protection Agency: Publications
An inventory of fishing on Norris, a storage reservoir, was begun in 1938. The following year it was extended to Wheeler, a run-of-the-river reservoir, and to the tailwater area below Wilson Dam. This inventory, therefore, covered each of the three general types of fish habitats created by the TVA dams. This discussion is a summary of the 1939 fishing data, together with recommendations for fish management based on the creel census information. The data collected totaled 34,270 usable fishing records, representing a catch of 98,495 fishes.

A Study Of A Carbonaceous Gold Ore, James S. Huckaba
Bachelors Theses and Reports, 1928 - 1970
The presence of graphite in the ore of the Missouri-McKee Mine has made its treatment by the methods now used quite unsatisfactory. The study was undertaken to develop a new flow sheet which would give a high recovery and yet be economical enough to handle low grade material.

A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz
A New Fossil Bovid From Nebraska With Notice Of A New Bison Quarry In Texas, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
An interesting and unique bovid skull was reported to the staff of the University of Nebraska State Museum in 1938 by Mr. Alvin McReynolds of Nehawka, Nebraska. The specimen was found in 1933 in a ravine north of Nehawka by Messrs. Merritt and Harold Dodson, brothers. Although the skull was not in place, it appears to have been washed out of a nearby Pleistocene clay deposit by floodwaters. The specimen is well preserved and is of a dark brown, almost black color. In 1938 it was loaned to the Museum for study and photographing but was not obtained as a …

The Ancestral Ursid, Hemicyon, In Nebraska, Edwin H. Colbert
Bulletin of the University of Nebraska State Museum (1924–2023)
During the summer of 1928, a University of Nebraska State Museum field party, composed of Dr. A. L. Lugn and the writer, made a collection of upper Miocene and lower Pliocene mammals in Brown and Cherry counties, Nebraska. This collection was sponsored and made possible by the generosity of the late Hon. Charles H. Morrill.

A Shovel-Tusked Mastodon, Arnebelodon Fricki, From Kansas, Erwin Hinckley Barbour, Claude W. Hibbard
Bulletin of the University of Nebraska State Museum (1924–2023)
Since the Amebelodontinae were first announced (Barbour 1927), a number of examples of the genus Amebelodon have presented themselves in various parts of Nebraska, Colorado, and in several places in Kansas. Thus its range has already been materially extended, many skeletal parts added, and the hope kindled that knowledge of this remarkable group of proboscideans is destined to be greatly enriched within the next few years. As may be seen in the accompanying lists of the known parts of Amebelodon preserved in various museums, there are already at hand the bones necessary for the assemblage of a nearly complete composite …
A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz
A New Species Of Sphenophalos From The Upper Ogallala Of Nebraska, Erwin Hinckley Barbour, C. Bertrand Schultz
Bulletin of the University of Nebraska State Museum (1924–2023)
The genus Sphenophalos was described by John C. Merriam (1909, p. 319-30), who based his description on a fragmentary horn-core (Uni. of Calif. No. 11887) from the late Tertiary deposits near Thousand Creek in northern Humbolt county, Nevada. Knowledge of Sphenophalos, however, is still confined to this single, fragmented type horn-core (Frick 1937, p. 472) and other fragmental specimens (Furlong 1932, p. 27-36).

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 …

Nebraska Tractor Tests
EXPLANATION OF TEST REPORT: John Deere AR
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.

Studies On The Quantitative Analysis Of Rhenium And Its Occurrence In The Products Of Molybdenite Processing, Walter Keith Dean
Studies On The Quantitative Analysis Of Rhenium And Its Occurrence In The Products Of Molybdenite Processing, Walter Keith Dean
Masters Theses
"There is at the present time no commercially developed source of the metal rhenium in the United States. Since this metal is known to exist in molybdenite, it was felt that a study of the products of the metallurgical processing of this mineral might reveal a source of rhenium that could e developed. The Climax Molybdenum Co. provided a number of samples from their smelter at Langloth, Pennsylvania. Although an improved method for the quantitative estimation of rhenium was recently published, its accuracy was not high and the procedure exacting and time-consuming. These combined factors led to the selection of …
