Bulletin No. 344 - The Nutritive Value Of Range Forage As Affected By Vegetation Type, Site, And State Of Maturity, C. Wayne Cook, Lorin E. Harris

UAES Bulletins

Native ranges of Utah are extremely heterogeneous. Pronounced variations exist in soil, seasonal rainfall, temperatures, and altitude on most grazing areas. Rough topography and micro-climates on even individual grazing allotments present variable vegetation types and site conditions. Such variations account for the comparatively large number of species and variable nutritive content found in range forage.

Methods Of Fiber And Paraffin Recovery From Waste Waxed Paper, Donald L. Huyser

Paper Engineering Senior Theses

Waxed paper is being used more and more every day in many ways. Its principle purposes are as wrappers or containers either to keep moisture out or in. Its uses vary from bread wrappers and drinking cups to metal parts wrappers.

For the most part, after the paper is used for its original purpose it is discarded and not salvaged like other waste paper. Also at the wax coating mills, the broke cannot be reworked with fresh stock. In most cases it is taken out and burned - not only being a total waste of stock but also a waste …

Observations On A Cyclic Decline Of Lemmings (Lemmus) On The Arctic Coast Of Alaska During The Spring Of 1949, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The importance to the biotic community of various species of lemmings in arctic and subarctic regions has long been recognized, but there is little known about the ecology of these mammals. of the two species that occur on the Arctic Slope of Alaska, namely, the collared lemming, Dicrostonyx groenlandicus rubricatus (Richardson), and the brown lemming, Lemmus trimucronatus alascensis Merriam, during the spring of 1949 the writer had the good fortune to observe a cyclic decline in the population of the brown lemming on the Arctic Coast of Alaska. Observations were made during the peak density preceding this decline and were …

Farmer's 1950 Income Tax, Agricultural Extension Service, South Dakota State College

SDSU Extension Circulars

Every person whose gross income during the year is $600 or more MUST file a return even though no tax is due. Gross income is total income (subject to tax) before any expenses are deducted. If at least two-thirds of your gross income is from farming and your business year starts January 1, you have two choices. Either, (a) File your return and pay the tax on or before January 31, 1951; or (b) File an estimate of your tax and pay this amount by January 15, 1951, then file your return and pay any balance due by March 15, …

Osteology Of The Skull Of Phrynosoma Cornutum (Harlan), Arthur J. Detrie

Field and Laboratory

The horned lizard, Phrynosoma cornutum, was first desscribed by Harlan as Agama cornuta; in 1831, J. E. Gray transferred the species to the genus Phrynosoma. Much work has been done on the species. Many of the references to Phrynosoma cornutum are of a taxonomic nature, while references to its morphology are few and the material in the papers is scant. Description of the osteology of the skull are lacking.

The Trichoptera Or Caddis Flies Of Dallas County, Texas, Clarence C. Hall Jr.

Field and Laboratory

Major contributions to our knowledge of American Trichoptera have been made (1934-47) by H. H. Ross, Cornelius Betten, and D. G. Denning. Their investigations, while concentrated in the eastern states, included some of the central states. Betten's work (1934) has been the basis for many recent studies. We know little, however, of the distribution of this order in Texas, even though it occurs abundantly in waters of the State. Most of the records for Texas were made in 1939 by H. H. Ross. In his report (1944), he recorded seven families and thirty species from Texas, ten of which were …

Farm Building Plans, Agricultural Extension Service, South Dakota State College

SDSU Extension Circulars

Buildings are a necessary part of each farm unit. They are used to provide shelter and facilities for farm family living, to house livestock, for storage and processing of food and feed, and for utility storage or service. Most farm buildings are designed to be used for many years. A carefully planned, well-located building carefully adapted to the use for which it is intended, is a profitable investment and a source of satisfaction. On the other hand, a poorly planned and improperly built structure may prove both costly and unsatisfactory. Every building on the farm represents a longtime investment and …

Bulletin No. 341 - Rambouillet And Columbia-Rambouillet Lambs On The Range And In The Feed Lot, T. Donald Bell, Milton A. Madsen, James A. Bennett, Louis L. Madsen, D. Clarence Schmultz

UAES Bulletins

Sheep of predominately Rambouillet breeding have been most popular on southern Utah ranges because of their hardiness and wool-producing ability. In the early years of sheep production in Utah a major portion of the income was derived from the sale of wool. This situation has gradually changed over the past years and now income from the sale of lambs is greater than that from fleeces. Rambouillet rams with improved mutton qualities have been used by some range operators to increase the mutton producing abilities of their ewes. Other operators have used Corriedale, Panama, Columbia, and other white faced crossbred-type rams …

Aircraft In Agriculture, N. E. Shafer, J. D. Furrer, J. W. Lomax

Nebraska Agricultural Experiment Station: Historical Circulars

Airplanes were first used in agriculture shortly after the close of World War I. They proved valuable for locating mosquito breeding areas, for forest fire patrol work, as an aid in locating outlaw cotton fields in the campaign against pink bollworm, and for surveying damage caused in large forested areas by the spruce budworm.

A Preliminary Note On Trichinosis Investigations In Alaska, P. J. Brandly, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Trichinosis in the arctic regions of the world has received considerable attention during recent years, particularly since the work of Roth (1948) in Greenland. In Connell's (1949) review of arctic trichinosis some Alaskan and Canadian records were included but, until now, little has been known of the status of the disease in Alaska. Information available at the present time indicates that the incidence of trichinosis is high in circumpolar carnivores and that marine mammals have a definite place in its epizootiology. Present knowledge cannot explain the survival of trichinosis in marine mammal populations, but it is evident that they may …

Distribution Of Mayfly Nymphs (Ephemeroptera) In Streams Of Dallas County, Texas, Louis E. Moore Jr.

Field and Laboratory

Although mayflies are of common occurrence in the Southwest, but little work has been done here on them. Most investigations on this group of insects have been done in New York, the Great Lakes Region, and Canada. Some work has been done in the Rocky Mountain area, and also along the Atlantic coast. Berner (1950) has published an extensive work on the mayflies of Florida. This is the first major work in this field since the book, Biology of Mayflies, by Needham, Traver, & Hsu (1935). Besides these, many minor papers on this group have appeared; but for Texas only …

4-H Project Guide : Swine Production, Clifford Iverson, James O'Connell

SDSU Extension Circulars

Choosing a Breed: The question "Which breed shall I raise" confronts every purebred hog producer. He may have a personal preference which will assist him in choosing a breed. If he has no such preference, it would be well worth while to consider the most popular breed in the community. This procedure will help the breeder to gain popularity, in establishing a reputation, and in attracting more buyers into the community. Each breeder may believe he has the best breed because of size, feeding qualities, higher dressing percentage or some other factor; but there is more difference within breeds than …

Bear River: A National Wildlife Refuge, Vanez T. Wilson, Rachel Carson

United States Fish and Wildlife Service: Publications

In the autumn of 1824 a buffalo-hide canoe drifted down the Bear River to its mouth in the Great Salt Lake of Utah. Within sight of that vast inland sea, Jim Bridger must have paused in amazement. Everywhere he looked-in the sky, on the open water, over the marshy borders of the lake-there were birds. It is said that the famous explorer of the western wilderness brought back reports that he had that day seen "millions of ducks and geese."

The Bear River marshes were soon to know years when their waterfowl were numbered, not by millions, but by thousands; …
