Ec32-134 Sweet Clover Management, P.H. Stewart, D.L. Gross

University of Nebraska-Lincoln Extension: Historical Materials

Sweet clover has made a phenomenal growth in popularity and acreage during recent years. In Nebraska, the production increased from 30,000 acres in 1920 to 1,126,000 acres in 1930, an expansion of over one million acres in a 10-year period. Just a few years ago, when sweet clover was classified as a weed, it was the subject of proposed state legislation to prevent its production and spread. Today sweet clover has a recognized place among standard crops and in rotation systems. The acreage of sweet clover in Nebraska is now practically equal to that of alfalfa and is more than …

Rb32-266 Cooling Milk On Nebraska Farms, P.A. Downs, E.B. Lewis

University of Nebraska-Lincoln Extension: Historical Materials

The desire of Nebraska people to continue the improvement of living conditions and to secure more healthful foods has been responsible for many changes in methods of caring for milk. One of the important factors in keeping milk sweet and of good quality is the process of cooling and keeping it cool until used. Three of these processes are as follows: placing containers of warm milk in any quantity of still water or still air at temperatures ranging from freezing to within a few degrees of the temperature of the milk, placing the containers in such positions that air or …

The Morphology Of The Seminal Vesicles, Accessory Glands, And The Ejaculatory Canal Of Melanoplus Differentialis (Thomas) And An External Morphological And A Histological Study Of The Seminal Vesicles, Accessory Glands, And Ejaculatory Canal Of This Grasshopper, Wilbur T. Reierson

Electronic Theses and Dissertations

The purpose of this thesis is to record the results of an investigation, by the writer, upon the reproductive system of Melanoplus differentialis (Thomas) with special emphasis placed upon the external morphology and the histological study of the seminal vesicles, accessory glands, and the ejaculatory duct; and also to record conclusions as to the probable function of these organs.

Some Effects Of A Constant Temperature And Different Relative Humidities Upon Egg Laying Of Melanoplus Bivittatus Scudder., Millard Jewell Hatten

Electronic Theses and Dissertations

Of the various species of grasshoppers occurring in rather extensive numbers year after year in the northwestern plains states, Melanoplus bivittatus is one of the most prevalent and destructive. It was thought that a study of the influence of different temperatures and relative humidities upon the reproductive potential of this species might reveal some information and that this information might be of some value in an attempt to forecast the abundance of this grasshopper in years following others in which the factors of temperature and relative humidity were known.

Farm Mortgage Experience Of Life Insurance Companies Lending In South Dakota, Harry Allan Steele

Electronic Theses and Dissertations

Life insurance funds play an important part in supplying farm mortgage credit. This source of credit has increased rapidly during the last twenty years and is now one of the principal sources of farm mortgage loans in the United States. Because of the nature of the institution of life insurance, its investments should be conservative. It is with this view in mind that the state insurance laws are designed to regulate the investments of the life insurance companies. Investments of the well established life insurance companies have generally been made on a conservative basis.

Anatomical Study Of Water Shoots And Ordinary Twigs, Dorothea I. Bingham

Electronic Theses and Dissertations

Water shoots or long shoots are those which appear low on the trunks of trees, or about stumps of trees recently cut down. The ordinary twigs are those found at the ends of branches. Interest in the cooperative study of water shoots and ordinary shoots on trees was aroused by the very marked differences, even in a single years growth, in length and the diameter of two types. The former is greater in diameter , much longer, and with more nodes, longer internodes and longer leaves than the twigs which grew ordinarily at the ends of branches. The object of …

Microfossils In An Arkansas Peat And Their Significance, Paul B. Sears, Glenn Couch

Papers in Ecology

This is an extension of a series of studies by one of the authors and his associates (1) on fossil pollen in peats of the North Central States. The purpose of such studies has been to secure information concerning the general trend of climate in postglacial time, as an aid in interpreting present vegetation.

These previous studies have indicated that postglacial climate has been largely of continental type, cool at first and later warm. Separating the cool dry from the warm dry period there appears to have been a definite although brief period of greater humidity, relative if not absolute. …

The Composition Of Soil Colloids In Relation To Soil Classification, Horace Byers, M. S. Anderson

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

For a period of approximately fifteen years investigators in the Bureau of Chemistry and Soils have been engaged in the accumulation of scientific data concerned with colloid material of the soil. During this period a large volume of accurate information has been secured which has been published in the form of bulletins and journal articles. So far as the Bureau publications are concerned, but little has appeared concerning theoretical aspects of the composition of the colloid. They have concerned themselves, for the most part, with methods of isolation and estimation, and determination of general physical and chemical characteristics.

A Study Of Poverty And Dependency In Phelps County For 1931, Arthur Royal Powell

Masters Theses

"The Ozark Region of Missouri is rapidly undergoing a definite social and economic change. thru markedly improved methods of communication and transportation the eighteenth century culture of this region is being metamorphosed into a twentieth century culture. Where the Ozarker of a generation ago was a strongly individualistic frontiersman in his outlook on life, he is now in the process of becoming a citizen of a larger and more complex society. The telephone, the radio, and the concrete highway, together with the cheap automobile, have made the customs and many of the folkways and mores of the Ozark people obsolete, …

The Ethnobotany Of The Acoma And Laguna Indians, George R. Swank

Biology ETDs

The Indian lives close to nature and utilizes the plants which grow about him, and these uses differ among various tribes. In order therefore to understand the ethnobotany of any group of Indians it is necessary to know something of their history, customs, mythology, religion and medicine. Hence in treating the ethnobotany of the Acoma and Laguna Indians the above phases of their culture will be discussed as they relate to these two pueblos.

Worm Parasites Of The Brown Rat (Mus Norvegicus) In The Philippine Islands, With Special Reference To Those Forms That May Be Transmitted To Human Beings, Marcos A. Tubangui

Harold W. Manter Laboratory of Parasitology: Library Materials

Summary

Besides the role that they play as carriers and reservoirs of bubonic plague and other bacterial as well as spirochretal infections, rats often harbor parasitic worms, some of which are also a menace to human health. In view of this and because of the fact that the helminthic fauna of rats has never been studied extensively in the Philippine Islands, it seemed desirable to undertake a systematic examination of these animals for the purpose of finding out if they are infested with parasites that are transmissible to man.

The examination of nine hundred fifty rats (Mus norvegicus) …

Circular No. 96 - Crickets And Grasshoppers In Utah, W. W. Henderson

UAES Circulars

In the written history of Utah, especially that which is reflected in diaries and journals of the pioneer settlers and that found in the oldest publications, there is ample evidence that one of the most serious handicaps to progress in this "far-western" territory was the cricket and its near kinsman, the grasshopper. Three basic resources on which the first permanent settlers counted were: (1) Good soil suitable for raising crops to sustain life; (2) suitable climate to make possible the maturing of wheat, corn, and vegetables; and (3) sufficient water of good quality not only for home uses but for …

Who's Who Among The Prairie Grasses, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

For many years I have lived on the prairie, where I became familiar with the grasses. Each spring I have been delighted with their renewal of growth in watching the brown landscape of rolling hills become carpeted with green. Year after year, with the progress of the season, I have seen the changing aspects, which, with the coming of autumn, end in the wonderful coloration of the prairie grasses. But the prairie as a whole has seemed a somewhat elusive thing, difficult to visualize, not easy to describe, indefinite and extremely variable in its composition. This vagueness of understanding, I …
