Egg Coolers For Better Eggs, Boyd J. Bonzer, Louis Lubinus Jun 1949

Egg Coolers For Better Eggs, Boyd J. Bonzer, Louis Lubinus

SDSU Extension Circulars

A recent study by the Research and Marketing administration showed that. South Dakota farmers are marketing only about 40 percent top quality eggs at the produce stations or first buyers. South Dakota is an egg exporting state and has to depend on Eastern and West Coast markets to buy three of every four eggs it produces. The consumers on these export markets are demanding a high quality egg, which leads to a great deal of discrimination against the low quality Midwestern eggs. Nearly all eggs are of top quality when they are laid. A very high percentage of the eggs …

Pink Rot Of Potatoes Caused By Phytophthora Erythroseptica Pethyb., R. W. Goss Jun 1949

Pink Rot Of Potatoes Caused By Phytophthora Erythroseptica Pethyb., R. W. Goss

Nebraska Agricultural Experiment Station: Historical Research Bulletins

During the summer of 1943 reports were received of rotted tubers occurring in fields of early potatoes in central Nebraska. An estimated 10 per cent of the tubers were found rotted in some fields on August 5. In November and December of the same year the late-producing area of western Nebraska reported the occurrence, at harvest and in storage, of tuber rots differing from those previously recorded for that area. Specimens appeared similar to those observed during the summer in central Nebraska. Isolations were made and pathogenicity tests were conducted both on tubers and growing plants to study the influence …

Notes On Winter Feeding Habits Of North Texas Bobwhites, Fred H. Wagner Jun 1949

Notes On Winter Feeding Habits Of North Texas Bobwhites, Fred H. Wagner

Field and Laboratory

From the viewpoint of the field biologist, Dallas is advantageously situated; for within a radius of less than a hundred miles one may reach six different principal soil types, each the result primarily of its underlying geological formation…. The problem of which this paper is the partial result, was an attempt to note differences or similarities in the feeding habits of bobwhites in these different regions (as affected by the soils through plant relationships.)


William D. Moore (1824-96), Amateur Geologist Of Mississippi, S. W. Geiser Jun 1949

William D. Moore (1824-96), Amateur Geologist Of Mississippi, S. W. Geiser

Field and Laboratory

It is now nearly ninety years since William D. Moore, then professor of English at the University of Mississippi, collaborated with Eugene W. Hilgard on his famous geological report of that State. The archivists and historians have lost Moore from their records (if, indeed, they ever sought seriously for information of him), so that what was written five years ago of W. D. Moore (in another connection) remains as true as it was then: "No record of whence he came, or whither went (when the University closed in 1861), is to be found at the Univer­sity." Since the present writer …


The Disappearance Of Plant Species From The Range In Texas, V. L. Cory Jun 1949

The Disappearance Of Plant Species From The Range In Texas, V. L. Cory

Field and Laboratory

My study of the range began in 1923. Since then, under conditions of continuous (and often excessive) grazing, I have observed that certain palatable species of range plants have disappeared, and others have been severely reduced in abundance. Doubtless other species vanished before 1923, when I began my observations.

Marketing Of Aspen, Zigmond A. Zasada Jun 1949

Marketing Of Aspen, Zigmond A. Zasada

Aspen Bibliography

The Lake States timber industry did a creditable job of producing and using considerable volumes of aspen during the war years. At that time it was shown that aspen could fill a variety of uses satisfactorily. However, improved marketing techniques are needed if present aspen stands are to be fully and profitably utilized. The aim of this paper is to call the attention of owners and producers of aspen to some of the points to be considered to improve marketing.


Aspen For Excelsior, Hereford Garland Jun 1949

Aspen For Excelsior, Hereford Garland

Aspen Bibliography

The use of aspen for the manufacture of excelsior is well established in the Lake States. The properties of the wood make it suitable for this general use, and there are adequate supplies available for increased productive capacity. The process of manufacturing excelsior is relatively uncomplicated, and the production equipment is simple and relatively low in cost. That the industry is not more extensive is obviously due to limitations in markets for excelsior. Expansion of the industry depends primarily upon the development of new uses and new products having excelsior as a base.


A Study Of Saponification Rates As Characteristic Of Esters, Thomas F. Mitchell Jr. Jun 1949

A Study Of Saponification Rates As Characteristic Of Esters, Thomas F. Mitchell Jr.

Bachelors’ Theses

The saponification of esters has been the subject of considerable study, and the technology of manipulation of the reaction well defined. As a result, the reaction has become a quantitative standard for ester analysis. However the comparison of the rates of this reaction with various esters as charaeteristic of them has received little consideration compared to the course of the reaction. The work of Mr. F. E. Adler on the adaptation of fat constants to waxes suggested the problem. The thesis will attempt to ascertain any significant differences in the saponification rates of various esters with regard to their characterization.


A Critical Study Of North American Cestodes Of The Genus Andrya With Special Reference To A. Macrocephala Douthitt, 1915. (Cestoda: Anoplocephalidae), Robert L. Rausch, Everett Schiller Jun 1949

A Critical Study Of North American Cestodes Of The Genus Andrya With Special Reference To A. Macrocephala Douthitt, 1915. (Cestoda: Anoplocephalidae), Robert L. Rausch, Everett Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Eight species of cestodes belonging to the genus Andrya Railliet, 1883, have been described from North American rodents. To the present time, 6 of these have been considered valid (A. primordialis Douthitt, 1915; A. macrocephala Douthitt, 1915; A. neotomae Voge, 1946; A. microti Hansen, 1947; A. sciuri Rausch, 1947; A. ondatrae Rausch, 1948). The genus Andrya was separated by Kirschenblatt (1938) into two subgenera, depending upon the presence or absence of a prostate gland. Of the North American species, only one (A. primordialis) possesses a prostate gland. Since we are concerned essentially with the other 5 closely-related …

A Study Of Fleas Of Rodents In The Albuquerque, New Mexico, Area, Lelia Ann Williams May 1949

A Study Of Fleas Of Rodents In The Albuquerque, New Mexico, Area, Lelia Ann Williams

Biology ETDs

In spite of the fact that Pasturella pestis, the the etiological organism of plague, has been reported from fleas and rodents in eleven counties of New Mexico, our knowledge of the fleas of the State has remained very incomplete and extremely meager. Recognizing the marked deficiency regarding our information of the Siphonaptera of New Mexico, I began in the spring of 1948 an investigation that has resulted in adding considerable information to our knowledge of the flea population of our State.

The present study includes a report of 36 species and subspecies of fleas recovered from several nests and by …


A Bioecological Study Of Pinyon Pine-Juniper Association At Juan Tabo In The Sandia Mountains Of New Mexico, Robert Hallett Parker May 1949

A Bioecological Study Of Pinyon Pine-Juniper Association At Juan Tabo In The Sandia Mountains Of New Mexico, Robert Hallett Parker

Biology ETDs

A survey of literature shows that no community or bioecological study has ever been made of the pinyon pine-juniper association as it occurs in the Upper Sonoran Life Zone in New Mexico and southern Colorado. This deficiency of knowledge relative to the pinyon pine-juniper community is in direct contrast to several studies that have been made of the same community in Arizona and Utah by the presence of dominant trees of entirely different species. Relative to the association in New Mexico, one of the dominant tress, the pinyon pine (Pinus edulis Engelm), has been investigated, but no bioecological and …

The Determination Of Choline Esterase Activity In Whole Brains Of Developing Rats, Charles Joseph Metzler May 1949

The Determination Of Choline Esterase Activity In Whole Brains Of Developing Rats, Charles Joseph Metzler

Biology ETDs

It is the purpose of this paper to report the results of quantitative investigations of the choline esterase activity in the rat in various states of its life cycle. Some work has been done on the acetylcholine content (Welsh and Hyde, 1944) in rats of various ages, but there is no reference in the literature to complete the quantitative determinations of the choline esterase activity in the whole brain of the rat throughout its life cycle.
