Why Doesn't Such-And-Such A Game Bird Do Well In Nebraska?, Levi Mohler
Why Doesn't Such-And-Such A Game Bird Do Well In Nebraska?, Levi Mohler
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
Why doesn't such-and-such game bird do well in Nebraska? This is a question which is often asked field workers for the game department. The answer to such an inquiry varies with the bird in question, but in general the following applies: Since climate, topography, and natural foods vary so much from place to place, and since most individual species are not highly adaptable, nature has through the centuries evolved many species, or kinds, of birds, each species adapted to meet certain conditions. Some of these have extensive ranges; others are limited in their distribution. The conditions suited to one species …

This report represents a compilation, analysis and summarization of data collected on the South Platte Management Area and deals primarily with game bird data collected by personnel of Project W-37-R. History, general description, and methods of operation are discussed, and recommendations for future operations given.
Briefly, the South Platte Management Area is located in Logan and Sedgwick counties, comprising over 11, 400 acres of state-owned land in four separate segments. The largest segment (more than 12,000 acres of deeded and leased land) lies along the South Platte River from Proctor to Red Lion. This, and a second area of 240 …
Spring Prairie Grouse Census - 1955, Reuel Janson
Spring Prairie Grouse Census - 1955, Reuel Janson
Nebraska Game and Parks Commission: White Papers, Conference Presentations, and Manuscripts
The 1955 spring prairie grouse census was conducted during the period March 30 to May 4. Census data were obtained by means of a survey of dancing and booming grounds on 18 automobile transects.
An average population density of 4.77 sharptailed grouse, and 0.71 prairie chickens per square mile was found. Comparable data for 1954 and 1955 indicate a 10 percent decline in the combined prairie and grouse population. The prairie chicken population declined considerably more than the sharptail population.
The extreme northern portion of the grouse range, Corson and Perkins Counties, experienced population gains of approximately 50 percent which …

The Separation Of Grain By Projection, Robert Katz, E. P. Farrell, Max Milner
The Separation Of Grain By Projection, Robert Katz, E. P. Farrell, Max Milner
Robert Katz Publications
A device is described which effects a continuous separation of internally infested wheat from sound wheat, and which separates wheat into a number of fractions of different test weight. A stream of wheat, projected into still air by rapidly moving belts, is dispersed by the combined effects of air drag and gravitation into numerous fractions which are caught in a series of hoppers. Infested kernels fall short of sound grain and are thus separated. Test weight varies progressively and characteristically with distance from the point of projection.

The Separation Of Grain By Projection. Ii. Systematic Differences In Physical Properties And Composition Of Wheat Fractions, Max Milner, E. P. Farrell, Robert Katz
Robert Katz Publications
Analyses for test weight, 500-kernel weight, protein content, ash content, and hardness characteristics of fractions of 15 samples of hard red winter wheat, obtained by spectrometric separation, revealed high negative correlations in most cases between plumpness factors and protein and ash contents, and high positive correlations between plumpness factors and hardness, when the latter is determined with a single-stage instrument. The projection technique appears to provide a means for analyzing commercially mixed wheat for certain qualities of its components and it may be applied practically to separate either high protein fractions or high test weight fractions from ordinary commercial grain.
