Citrus Notes-Handling The Orange-Riverside1909, Charles C. Chapman

Charles C. Chapman Citrus Speeches

This speech was presented to the Riverside Y.M.C.A. on April 13, 1909. Mr. Chapman discusses the necessity of careful handling of the orange, from the tree to the market, so that the oranges are not bruised or damaged. He delves into details such as using the right kind of clippers, placing the fruit in clean picking bags and boxes that are the right size, using the right kind of ladder, and wagons with springs to properly transport the oranges.

Oats, E. G. Montgomery

University of Nebraska Historical Extension: Bulletin

There is no more serious question confronting .the Nebraska farmer today than the oat problem. During the past few years, farmers generally believe they have lost money on the crop. It is necessary to grow some spring grain crop, and while many are looking for a substitute, such as barley, speltz, and spring wheat, yet none of these crops takes the place of oats in a satisfactory manner. While soil fertility must receive immediate attention, still our yields would be decidedly increased thru the. use of varieties best adapted to the region, with good preparation of the seed·bed drilling with …

The House Fly (Musca Domestica) And Allies, Lawrence Bruner

Department of Entomology: Faculty Publications

"Of what use are flies, anyway?" This and similar questions have frequently been asked of the writer by persons who seem to think that each and every living thing has been created solely for some special benefit to man.

Primarily the common house fly (Musca domestica), together with several of its allies which habitually frequent human habitations, are scavengers. In this role they assist in the removal of filth and litter of various sorts that too often are permitted to accumulate in the vicinity of our homes, schools, offices, and ' places of business or pleasure. These flies …

Bulletin No. 104 - The Storage Of Winter Precipitation In Soils, John A. Widtsoe

UAES Bulletins

It has been found that the production of one pound of dry plant substance on soils of average fertility, requires in humid districts not more than five hundred pounds of water, and in arid districts like Utah about seven hundred and fifty pounds. This indicates that the average rainfall of Utah, which is about twelve inches, if properly conserved in the soil, is sufficient to produce annually, without irrigation, from thirty to forty-five bushels of wheat to the acre, or corresponding yields of other crops. The realization of this truth has changed greatly our views of irrigation practices. The beginning …

The Sphegoidea Of Nebraska, Harry Scott Smith

University Studies (University of Nebraska) (1888–1984)

The following paper is the result of a study pursued by the writer at odd intervals during the past two years, and is based on the material contained in the collection of the University of Nebraska. Although the list is a fairly large one for a single state, nothing like systematic collecting has been done on the group, and it is expected that a great many additional species will be found in the near future. The only portion of the state that has been at all closely collected is Sioux county, where, during the past ten years, several zoological expeditions …

Histological Studies In The Artemisia Formation, Raymond John Pool

University Studies (University of Nebraska) (1888–1984)

Many investigators have written on the subject of leaf histology and morphology in general, and a few have, in addition, touched upon the physiological significance of structures found during the progress of the study. Among these writers are Haberlandt, Pick, Stahl, Bonnier, Wagner, Hesselmann, and Clements. Most of the work, however, has been purely histological or morphological with little or no reference to environic forces. But in these later days of the development of the new ecology those forces or factors which have been potent in the evolution of plants and which are moulding plants today have come under careful …

A Plea For The Protection Of Our Birds, Lawrence Bruner

Department of Entomology: Faculty Publications

The fact that insect depredations are increasing in extent each succeeding year makes it plain to us that something must be done to prevent it, and that quickly. We have found to our sorrow that, although we are continually making increased efforts to destroy these pests, our efforts avail but little and the destruction of our crops goes on. What, then, is to be done? How can we be released from this ever-increasing struggle for existence? The answer is plain. Heed the advice of the Naturalist who has made a study of the life-histories of the various other living creatures …

The Arrhenuri Of The United States, Ruth Marshall

School of Biological Sciences: Faculty Publications

The Arrhenuri comprise the largest genus of the Hydrachnidz, and one of the most highly differentiated and widely distributed. The genus is easily recognized by the following characters. The thick chitinous covering of the body is pierced by large pores. A circular furrow on the dorsal side marks off an area which is entirely enclosed in the female, in the male usually open onto the posterior extension of the body. The females are oval in form and much alike ; the males are smaller and vary greatly from each other and from the females. They are characterized by a posterior …
