Bulletin No. 336 - Utah Agricultural Experiment Station Biennial Report, 1946-1948, R. H. Walker

UAES Bulletins

During the past biennium there has been a general expansion in the research program of the Agricultural Experiment Station. This was made possible through increased state legislative appropriation and through federal funds made available by the Agricultural Research and Marketing Act which passed Congress in August 1946, although funds were not available until August 1947. Grants-in-aid by state and private agencies have also made other research possible.

Notes On Texas Compositae-I, Lloyd H. Shinners

Field and Laboratory

In the introduction to the unabridged edition of his Study of History (1933), Toynbee comments on the invasion of the field of scientific investigation by the Industrial System: the working up of raw materials ("data") by many individual workers ("scientists") into finished products ("papers," or as so commonly designated, "the literature"), according to more or less standardized methods of mass production ("Research"). Toynbee leaves it an open question whether this is not after all the best manner in which scientific investigation should be conducted in the present stage of development of western science. Certainly the magnitude of the task makes …

Rapid Methods For Killing Planaria And Lumbricus In An Extended Condition, Ottys Sanders, Nina S. Brown

Systems Of Producing Fat Yearlings For South Dakota, William Clark Mccone

Electronic Theses and Dissertations

About twelve billion pounds of dressed beef and veal were produced in the United States in 1947 through the conversion of grassland crops into meat by cattle and these cattle lead all classes of American livestock in the consumption of grass and grassland crops. Grass usually represents the principal and cheapest feed for beef cattle. They utilize about one third of the permanent pastures and three fourths of the range areas. Pastures may be regarded as a costly source of feed only on highly productive farm lands, but their use in rotation with cultivated crops on such land is certain …

The Apparent Digestibility By Sheep Of Prairie Hay Harvested At Three Stages Of Maturity, Robert Manseau Jordan

Electronic Theses and Dissertations

Grass is the greatest asset of the Northern Great Plains. Grass does and must serve as the basic feed for the flocks and herds of this area. Without grass, much of the Northern Great Plains would be waste land with little or no value. In the states of North and South Dakota, Nebraska, Colorado, Wyoming, and Montana, about 67 per cent of the total land is in pasture and hay. Seventy five to 95 per cent of the total feed needed by cattle and sheep in the Northern Plains states is furnished by pasture and roughage. With an ever-increasing demand …

Injurious Effects From Contacts With Millipedes, Bruce W. Halstead, Raymond Ryckman

Medical Arts and Sciences: A Scientific Journal of the College of Medical Evangelists

Millipedes are probably among the least mentioned of the so-called "medically important arthropods." Perusal of a number of the more common texts dealing with the entomological aspects of medicine (Belding, 1942: 600, Craig and Faust, 1940:511, Herms, 1946: 539, Mackie, Hunter, and Worth, 1945:515) revealed the concept, which is commonly believed, that millipedes are not capable of producing injurious effects. A recent experience of the senior author and additional investigation by both writers have prompted the writing of this paper in an effort to broaden scientific thinking regarding the medical significance of this animal.

A Study Of The Heel Flies, Hypodermia Lineatum Devillers And Hypoderma Novis Degeer, In South Dakota, John A. Lofgren

Electronic Theses and Dissertations

The heel flies or ox-warble flies and their larvae, commonly called cattle grubs or warbles, are among the most troublesome and costly insect pests of livestock producers in South Dakota. These parasites attack cattle almost exclusively although they may occur at times in other domestic and in wild animals. Infestations in man have been recorded, but these cases are quite rare. This work deals only with the occurrence of the parasites in cattle.

The Lemming Vole, Synaptomys Borealis, In Northern Minnesota, Ralph M. Wetzel, Harvey L. Gunderson

University of Nebraska State Museum: Mammalogy Papers

Lemming voles of the subgenus Mictomys have never been recorded from north-central United States, although they might be expected to occur there judging from records of the species Synaptomys (Mictomys) borealis from southern Manitoba. Recently, examination of specimens in the collection of the Minnesota Museum of Natural History reveals that Synaptomys borealis does occur in north-central United States for we have found the following specimens referable to that species: one immature female (No. 951, MMNH) from Williams, Lake of the Woods County, Minnesota, collected by Gustav Swanson, August 5, 1932; one adult male (No. 2552, MMNH) from Warroad, Roseau County, …

The Effect Of Age Of Gilt On Size Of Litter, Clifford Inman Iverson

Electronic Theses and Dissertations

Size of litter is an important consideration in determining the profits from a swine production enterprise. Basic information concerning factors affecting litter size is, therefore, pertinent to the swine production industry. This study was conducted to ascertain the effect of age of gilt on the size of their first litters.

Drug Plants Of California, Frederick Louis Beauchamp

University of the Pacific Theses and Dissertations

Many books and articles have been written covering the flora of California. Few, however, have dealt specifically with those plants yielding drug principles used in the materia medica of the medical and pharmacy professions. Over one thousand different species of native and introduced drug plants are growing in the state. Many of these, it is true, have fallen into disuse, either because of lack of medicinal value, or substitutes have been found in the laboratories of the chemist.

The development of the drug farming industry will not only give employment to the state’s increasing population, but will enable our nation …

4-H Club : Clothing Project "B" Plan, Anna Walker

SDSU Extension Circulars

How the teen-age girl can cover all the necessities of the wardrobe plus the · very special articles of clothing every girl loves might be answered by the slogan "sew your own, and select with care." For school the teen-ager needs clothes that are comfortable and easy to wear as well as smart. Most girls agree that Jeans and Sloppy Joes go for picnics but when it comes to school and occasions where she is out among folks; and wants to look her best it is important to be dressed in "girl's clothes."

Effects Of Weather, Sanitation And Chlorinated Chemical Residues On House And Stable Fly Populations On Nebraska Farms, Martin H. Muma, Ephriam Hixson

Department of Entomology: Faculty Publications

Since L. O. Howard's (1906) early report on house flies many entomologists have conducted research on these insects. Their reports range from notes on the hibernation of house flies, Musca domestica L., to lengthy papers on the biology and control of house flies and stable flies, Stomoxys calcitrans (L.). Early control studies stressed the importance of sanitatioll, screening and the use of mist type contact insecticides. These standard control measures have not, however, received much attention in the United States since Wiesmann (1943) reported on the pro-longed effectiveness of a new insecticide "Gesarol." Scores of other workers have also published …

Mechanical Transmission Of A Plant Tumor Virus To An Insect Vector, Karl Maramorosch, Myron K. Brakke, L. M. Black

Department of Plant Pathology: Faculty Publications

Most plant viruses transmitted by leafhoppers have not been demonstrated to be infective in extracts. The virus dealt with in this paper causes tumors in certain susceptible plants, is carried by leafhoppers, and like others in that group has proven difficult to detect in extracts. It is our purpose to recount briefly the variety of methods that failed to transmit the virus and to report on the success of insect-to-insect transmission by injection.

Evidence For A Tryptophane Cycle In Neurospora, Francis A. Haskins, Herschel Mitchell

Department of Agronomy and Horticulture: Faculty Publications

The work of Snell on lactic acid bacteria provided the first evidence that anthranilic acid may act as a precursor to tryptophane in vivo. Since the strains of bacteria which utilize anthranilic acid in the place of tryptophane also use indole, it was not possible to establish the order in which these two precursors occurred. In 1943 Tatum, Bonner and Beadle found that anthranilic acid was accumulated in the culture medium by a Neurospora crassa mutant, strain 10575, which required either tryptophane or indole for growth. It was therefore indicated that anthranilic acid is a precursor to indole in …

The Occurrence Of Platynosomum Illiciens (Braun, 1901) In A North American Hawk., J. Fred Denton, Robert Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A series of 160 hawks of 12 species from ten states and the Province of Manitoba has been examined for dicrocoeliid trematodes. Only one species of dicrocoeliids was found in them indicating the infrequency with which North American hawks are infected with trematodes of this group.

Of the 160 hawks examined 4 were broad-winged hawks. Buteo platypterus, 2 of which, collected in Ohio and Wisconsin, harbored in their bile ducts 3 and 8 specimens respectively of a trematode of the genus Platynosomum. These specimens, after comparison with both the original and the recently expanded description by Travassos (1944, …

Some Observations On Cestodes Of The Genus Paranoplocephala Luehe, Parasitic In North American Voles (Microtus Spp.), Robert Rausch, Everett L. Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Although cestodes of the genus Paranoplocephala Luehe, 1910, are common parasites of voles and certain other rodents in North America, their taxonomic status to the present time has been much confused. It is the purpose of this paper to clarify the situation in regard to those species parasitic in voles of the genus Microtus Schrank.

While certain of the cestodes considered here occur in hosts of other microtine genera, they are by far more abundant in the various species of Mi· crotus. At least two are also common in geomyid rodents. With the possible exception of Paranoplocephala brevis Kirschenblatt, …

Studies On The Parasitic Helminths Of The North Central States. Ii. Helminths Of Voles (Microtus Spp.) Preliminary Report, Robert L. Rausch, Jack Tiner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The helminths of North American mouse-like rodents have received little study. Previous work has been based on low numbers of animals examined, and there has been little reference to the ecology involved. The purpose of this paper is to present data resulting from the examination of over 600 voles, with special reference to host-parasite relationships

A Survey Of The Adult Trematodes From Fishes Of The Pacific Marine Station Area, William Franklin Johnson

University of the Pacific Theses and Dissertations

An effort is here made to assemble all of our knowledge of all adult trematodes which have been found in the fishes of the Pacific Marine Station Area. This includes publications, unpublished material such as graduate theses, and specimens herein described for the first time. It is hoped that this endeavor will facilitate further investigation in trematodology and that this paper will be an aid in identification of trematodes subsequently discovered.

Studies On Larval Trematodes From Tomales Bay, California, Leroy H. Fisk

University of the Pacific Theses and Dissertations

Very little is known of the development, life history, economic importance, of biological relationships of larval trematodes, especially in their molluscan and arthropod hosts on the Pacfic Coast. The comparatively few contributions to our knowledge have been from scattered and fragmentary observations. The purpose of this study was to expand our knowledge and to lay a foundation for further work on trematode life cycles in marine organisms. The area selected for special investigation was Nick's Cove, Tomales Bay, California.

Nebraska Agricultural Experiment Station: Historical Circulars

Tests conducted during the past four years at the Nebraska Agricultural Experiment Station have shown that when seeds are planted in cold, wet soils, better stands of vigorous seedlings are generally obtained when the seeds are treated before they are planted.

Preliminary Geomorphological Studies Of The Lime Creek Area & Preliminary Report On The Lime Creek Sites: New Evidence Of Early Man In Southwestern Nebraska, C. Bertrand Schultz, Gilbert C. Lueninghuener, W. D. Frankforter

Bulletin of the University of Nebraska State Museum (1924–2023)

PALEONTOLOGICAL and archaeological discoveries were made near Cambridge, Nebraska, by the University of Nebraska State Museum field party in the spring of 1947 (Schultz and Frankforter, 1948, pp. 279-280) . Fossils and artifacts were found in situ at the base of a fifty-foot terrace on Lime Creek (University of Nebraska State Museum Localities Ft-41 and Ft-42) and on Medicine Creek just below the mouth of Lime Creek (Ft-50). Lime Creek is located (Fig. 1) in southwestern Nebraska in the southeastern part of Frontier County. It is a tributary of Medicine Creek which in turn is a tributary to the Republican …
