Type Of Farming Study Manual For The United States And South Dakota, C. R. Hoglund
Type Of Farming Study Manual For The United States And South Dakota, C. R. Hoglund
Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)
This pamphlet was prepared especially for teaching guide in farm management courses at South Dakota State College. It should help acquaint students with the geography of crop and livestock production in the states and regions of the United States as well as in the various counties of South Dakota. This material should also be of value to research and extension workers in agriculture. Vocational agricultural instructors may also benefit by studying the maps and other data presented. The concentration of specific crop and livestock production in the various areas of South Dakota and the United States is not due to …
Trypsin Inhibitor. V. Nutritive Value Of Treated Soybean Oil Meal And Some Characteristics Of The Trypsin Inhibitor In Soybeans, Raymond Borchers, W. E. Ham, R. M. Sandstedt, C. W. Ackerson, R. H. Thayer, F. E. Mussehl
Trypsin Inhibitor. V. Nutritive Value Of Treated Soybean Oil Meal And Some Characteristics Of The Trypsin Inhibitor In Soybeans, Raymond Borchers, W. E. Ham, R. M. Sandstedt, C. W. Ackerson, R. H. Thayer, F. E. Mussehl
Historical Research Bulletins of the Nebraska Agricultural Experiment Station
The marked improvement in the apparent nutritive value of soybean protein after heating has long been recognized. The fundamental cause of this improvement has never been fully understood. Furthermore, commercial soybean oil meal varies considerably in nutritive value although heat treatment is common in most processing plants. Since heating is generally regarded as deleterious to the nutritive quality of protein, the following investigations of various treatments of soybean oil meal are of particular importance in developing a soybean or soybean oil meal of maximum and uniform nutritive value.

A Preliminary Study Of A Physical Basis Of Bird Navigation, Henry L. Yeagley
A Preliminary Study Of A Physical Basis Of Bird Navigation, Henry L. Yeagley
Papers in Ornithology
The bird navigation theory as presented implies an organ or organs in the bird's physiology which are sensitive to the effect of its motion through the vertical component of the earth's magnetic field and to the effort exerted to overcome the coriolis force, due to the earth's rotation. Both these influences involve a set of lines which together form a navigational gridwork. By correlating its instantaneous land speed with the two above effects, a bird can fly to its home which is a unique point in this gridwork, or to related companion points existing in the gridwork at positions other …
Early Life History Of The Oyster Crab, Pinnotheres Ostreum (Say), Mildred Sandoz, Sewell H. Hopkins
Early Life History Of The Oyster Crab, Pinnotheres Ostreum (Say), Mildred Sandoz, Sewell H. Hopkins
VIMS Articles
The first and second zoeae of Pinnotheres ostreum have been described Hyman (1924). The five crab stages parasitic in the oyster (Ostrea virginica) have been described by Stauber (1945). The present paper is an attempt to plete the knowledge of the development of the oyster crab from the egg to the first crab instar. This work was done at the Virginia Fisheries Laboratory in summer of 1944, under the direction of Dr. Curtis L. Newcombe.
The first Pinnotherid larva to be described was the zoea of Pinnotheres pisum Leach, the British pea crab. This species has three or more zoeae. …
Chemical Utilization Of Aspen, Geo J. Ritter, Ralph L. Hossfeld
Chemical Utilization Of Aspen, Geo J. Ritter, Ralph L. Hossfeld
Aspen Bibliography
Chemical utilization of raw materials depends largely on the chemical composition and the chemical and physical properties of the raw materials under consideration. The utilization of wood is no exception to this principle. Thus, a wood having a low percentage of cellulose is uneconomical as a source of wood sugar or pulp for paper; and one of an excessively knotty character is undesirable for chemical conversion Woods having several undesirable characteristics generally fall within the classification of species little used for the purpose. Fortunate! aspen falls outside this class.
Aspen Lumber For Building Purposes, Louis W. Rees
Aspen Lumber For Building Purposes, Louis W. Rees
Aspen Bibliography
Recent shortages of lumber for building purposes make it desirable to seek out all possible supplies of additional lumber. Aspen, according to a study made in northern Minnesota during 1944, 1/ may be a source of lumber largely untapped. The results of that study are the main basis of this paper.

Killing, Dressing And Drawing Poultry, I. L. Williams
Nebraska Agricultural Experiment Station: Historical Circulars
The object of this circular is to acquaint poultry producers and poultry dressing plant operators with the more desirable methods for killing, dressing and drawing poultry. Dressed poultry is a highly perishable food, and any practice that will tend to retain the original high quality during the processing operation should be applied.
Seasoning Of Aspen, Harvey H. Smith
Seasoning Of Aspen, Harvey H. Smith
Aspen Bibliography
Aspen is nor; the major forest type in the Lake States, and extensive stands are reaching maturity. Increasing quantities are being cut, and much is nor; being put to new and more exacting uses that require better air - seasoning and kiln-drying practices. The recent favorable market for green aspen lumber appears to be falling off, and the time may soon come when operators are no longer able to move green aspen. Such a change can be met by manufacturing better-quality aspen lumber and by carefully seasoning it to the desired moisture content to make it more acceptable. This report …
Machining And Related Properties Of Aspen, Edward M. Davis
Machining And Related Properties Of Aspen, Edward M. Davis
Aspen Bibliography
Aspen occupies 20 million acres of Lake States timber land, or 39 percent of the total forest area. In 1945 there were 6 1/3 billion feet of aspen saw timber 9 inches d.b.h. and larger, and a larger cubic volume of smaller material. The cut of aspen lumber was 152 million board feet in 1946, and the forest could sustain a much larger annual cut.

Thinking Of Others At Christmas, Anna M. Wilson
SDSU Extension Circulars
A true gift is a joy to give and a pleasure to receive. Such a gift doesn't just happen, it grows. It takes thought and planning. Then it takes some doing. Gifts made at home will not stretch the purse strings too far, and they can be hand-tailored to the friend. The best gift may not be wrapped in tissue and ribbon-it might be an invitation to a Christmas tea party. Thinking of others will make Christmas the most joyous season of the year-as it should be.

Bakererpes Fragilis N. G., N. Sp., A Cestode From The Nighthawk (Cestoda: Dilepididae), Robert L. Rausch
Harold W. Manter Laboratory of Parasitology: Faculty and Staff Publications
The examination of an Eastern Nighthawk (Chordeiles m. minor (Forster)), collected September 25, 1945, at Marion, Ohio, revealed numerous, very small cestodes free in the lumen of the small intestine. About fifty specimens were found, but, because of the delicate strobila of this species, few were entire.
Although these cestodes were very thin and translucent, the preparation of well-stained whole mounts presented unusual difficulty. Best results were obtained with a mixture of Ehrlich's and Delafield's haematoxylin stains. Frontal and transverse serial sections, cut at 10 and 15 μm, were made.
This cestode clearly belongs in the sub-family Dilepidinae, but, …

Milling Of Aspen Into Lumber, C. J. Telford, F. B. Malcolm
Milling Of Aspen Into Lumber, C. J. Telford, F. B. Malcolm

In the manufacture of aspen lumber, the costs of stumpage and logging approximate 65 per cent of the total, and milling and sales 35 per cent. Milling efficiency is essential, but by itself it is not assurance of a profitable operation.
Aspen For Pulp And Paper, E. R. Schafer
Aspen For Pulp And Paper, E. R. Schafer
Aspen Bibliography
Although the use of hardwoods for pulp and paper manufacture has increased considerably during recent years in the Lake States, the pulpwood consumed in this region consists largely of softwood species of which about one quarter is obtained from foreign sources. The wood resource, on the other hand, is comprised to a large extent of hardwoods, predominantly aspen, with the maples, oaks, and several other species available in lesser amounts. The present stand of aspen in the Lake States is estimated at nearly 20 million acres with a total volume of merchantable timber of about 32 1/2 million cords. The …
