Spraying As An Essential Part Of Profitable Apple Orcharding, R. A. Emerson, R. F. Howard, V. V. Westgate

University of Nebraska Historical Extension: Bulletin

It was therefore planned from the start not merely to demonstrate the possibility of controlling apple insects and diseases but also to determine whether they could be controlled profitably. To accomplish this it was necessary to know: exactly what it cost to spray, what sprayed fruit yielded, and what it was worth in comparison with unsprayed fruit from the same orchards. In every spraying demonstration the time spent in mixing and applying the materials and the quantity of material used were recorded. The cost of labor of men and teams per hour was taken at the orchard owners' estimates and …

The Present Methods Of Teaching Entomology, J. H. Comstock

Department of Entomology: Faculty Publications

The present methods of teaching entomology followed in the United States have been developed almost entirely by men now teaching this subject. A second generation of teachers has begun its work; but the first is still on the stage. We h3i¥e progressed far enough, however, to make it worth while for the teachers to compare methods, in order that each may profit by the experience of the others. In a conference of this kind the contribution of each to the discussion will be, naturally, at first, merely a statement of the methods evolved in our several widely separated institutions. Then …

Present Methods Of Teaching Entomology, H. T. Fernald

Department of Entomology: Faculty Publications

In teaching entomology, much depends upon the ultimate aim of the student. A course in introductory entomology, whether as a required or an elective subject is sure to include many students who will not continue the subject farther. It is at least probable, that these students will form over half of the class, and accordingly, the introductory treatment should be arranged on the basis of the greatest good to the greatest number. This will usually mean some slight knowledge of insect anatomy, particularly external anatomy, and a general survey of insects as a group, with special attention to the pests …

The Present Methods Of Teaching Entomology, Herbert Osborn

Department of Entomology: Faculty Publications

In a discussion of the methods of teaching entomology, it is almost necessary to take a hasty view of the growth of the subject and of the different methods of imparting knowledge in it during the past half century. We need scarcely go back of this, because for the United States, at least, the growth of the teaching of entomology as a subject included in a college curriculum has had its growth within that time. In fact, practically all of the development of the teaching outside of two or three localities has been within the last twenty-five' years. Naturally the …

Diese Art tritt in 3 verschiedenen Formen auf: 1. einer Frühjahrsgeneration mit dunklem Hinterleib, A. Trimmerana K., 2. einer Frühjahrsgeneration mit teilweise rotem Hinterleib, A. spinigera K., und 3. einer Sommergeneration, A. Rosae Pz. Der erste, welcher die Zusammengehörigkeit dieser 3 Formen oder Rassen erkannte, war Edward Saunders. In seiner Synopsis of British Hymenoptora, P. I. (Trans. Ent. Soc. 1882, p. 243) zieht er A. spinigera K. als Varietät zu A. Trimmerana K., und in den Hymenoptera Aculeata of the British Islands 1896, p. 237, werden die beiden genannten Formen als Varietäten zu A. Rosae Pz. gestellt. Meines Erachtens dürfen …

I make a new name for our species without hairs on the metanotum, not knowing whether it will include the typical Ageuia or not. The type of Melanaporus Ashm. is a two-celled form of P. argenteus or a close ally.

The Aspens: Their Growth And Management, William Grant Weigle, Earl Hazeltine Frothingham

Aspen Bibliography

The aspens, or "popple," as they are often collectively termed, occupy a peculiar position in the forests of North America. Growing up rapidly and in great abundance over areas which have been deforested, usually by fire, they attain only a small size, produce a soft, weak wood, extremely valuable for a limited number of uses, and die at a relatively early age.

Present Methods Of Teaching Entomology At The University Of Nebraska, Lawrence Bruner

Department of Entomology: Faculty Publications

'When our Secretary sent out his preliminary notification of this meeting and asked me to take part in a discussion of "present methods of teaching Entomology," the matter at first seemed of little importance so far, at least, as the speaker was concerned. However, after giving the subject some thought I have decided that it might be well at least to take the time and trouble to attempt to explain briefly a few of the methods by which the student in Nebraska is enabled to absorb some entomological information. In order to do this with an unbiased feeling it might …

Discussion And Correspondence Coupling Vs. Random Segregation, R. A. Emerson

Department of Agronomy and Horticulture: Faculty Publications

To the editor of science: The suggestion offered by Morgan, in SCIENCE of September 22, to account for the coupling and repulsion of factors for various characters in inheritance in such forms as Abraxas, Drosophila, fowls, sweet peas, etc., incites this note.

Briefly Morgan's hypothesis is (1) that the materials representing factors that couple are "near together in a linear series" in the chromosomes; (2) that, when pairs of parental chromosomes conjugate, "like regions stand opposed "; (3) that "homologous chromosomes twist around each other," but that the separation of chromosomes is in a single "plane"; (4) that, thereby the …

Botanical Teaching, Charles E. Bessey

Some months ago a suggestion was made that at this dinner we should ask ourselves the question: Why is it that with the enormous classes we are having in botany there is a marked dearth of properly trained men who can serve as instructors in colleges and universities?

New Elementary Agriculture, Charles E. Bessey, Lawrence Bruner, Goodwin D. Swezey

School of Biological Sciences: Faculty Publications

This is an agricultural nation. The products of the soil are the basis of her industries and her prosperity. The children of our great Commonwealths should be familiar with our crops, our grains and grasses, our flowers and fruits, our trees and shrubs and weeds, our domestic animals and birds and insects. Our children should have a practical knowledge of the management of a farm, of the composition of the soil, and of the adaptability of the farm and its soil for the cultivation of certain plants and the counter effect of such plant growth upon the soil. They should …

In the year 1905, Drainage Investigations were begun in the State of Utah by the Office of Experiment Stations of the United States Department of Agriculture, in co-operation with the Utah Experiment Station. Appropriations have been made by the Utah State Legislature for irrigation and drainage investigations on condition that the United 8tates Department of Agriculture contribute an equal amount, and that the work be conducted jointly by the Federal department and the experiment station of the Agricultural College of Utah.

Bulletin No. 113 - The Influence Of The Combined Harvester On The Value Of The Wheat, Robert Stewart, C. T. Hirst

UAES Bulletins

The extension of the dry-farming area in Utah and the bringing of many thousands of acres of virgin land under wheat cultivation, in large farms, has, in recent years, caused much improvement in the use of farm machinery. One great improvement has been the adoption of the Combined Harvester, which cuts, threshes and sacks the grain in one operation in the field at a minimum of cost. This has been an important factor in the success of the dry-farming movement.
