Circular No. 96 - Crickets And Grasshoppers In Utah, W. W. Henderson Nov 1931

Circular No. 96 - Crickets And Grasshoppers In Utah, W. W. Henderson

UAES Circulars

In the written history of Utah, especially that which is reflected in diaries and journals of the pioneer settlers and that found in the oldest publications, there is ample evidence that one of the most serious handicaps to progress in this "far-western" territory was the cricket and its near kinsman, the grasshopper. Three basic resources on which the first permanent settlers counted were: (1) Good soil suitable for raising crops to sustain life; (2) suitable climate to make possible the maturing of wheat, corn, and vegetables; and (3) sufficient water of good quality not only for home uses but for …

The Alkaloids, Felix F. Barre Jul 1931

The Alkaloids, Felix F. Barre

Electronic Theses and Dissertations

This thesis, presented for the degree of Bachelor of Science, provides a systematic chemical study of the alkaloids, a class of complex nitrogenous plant substances possessing basic properties. Barre opens by defining the alkaloids and surveying the various systems used to classify them, whether by natural versus artificial origin, chemical nucleus (pyridine, quinoline, or isoquinoline), volatility, or botanical family of origin, and outlines their general physical and chemical properties, including solubility, optical activity, and characteristic reactions with precipitating and color-test reagents.

The thesis details standard laboratory methods for the extraction and separation of alkaloids from plant material, including a step-by-step …


Circular No. 94 - Control And Eradication Of Bang's Abortion Disease, D. E. Madsen, W. H. Hendricks Jun 1931

Circular No. 94 - Control And Eradication Of Bang's Abortion Disease, D. E. Madsen, W. H. Hendricks

UAES Circulars

The seriousness of Bang's abortion disease in Utah has made it necessary to promote more definite plans toward its control and eradication. The economic losses encountered are brought about not only through the loss of the calves but by the lessened milk production and lessened sale value of the animals themselves. Breeding efficiency is lower and such cows are more subject to udder infections. Many states now require that cattle shipped into them be negative to the abortion test; indications are that more states will adopt similar regulations. The passage of such regulation by some states would seriously interfere with …


Bulletin No. 229 - Production Study Of 160 Dairy Herds: Wellsville, Utah, 1929, George Q. Bateman Jun 1931

Bulletin No. 229 - Production Study Of 160 Dairy Herds: Wellsville, Utah, 1929, George Q. Bateman

UAES Bulletins

The condensed milk plant located at Wellsville, Utah, could use more milk to an advantage. The dairymen of the section were anxious to supply this demand. The dairymen and manufacturers cooperatively planned a survey to determine by what means this demand could be brought about: Should the dairymen increase the size of their herds? If not, what could be done to increase dairy production?


Bulletin No. 230 - San Juan County Experimental Farm: Progress Report, 1925-30, Inclusive, James H. Eagar, A. F. Bracken Jun 1931

Bulletin No. 230 - San Juan County Experimental Farm: Progress Report, 1925-30, Inclusive, James H. Eagar, A. F. Bracken

UAES Bulletins

San Juan County, located in the southeast corner of the state, has a dry-farm area of approximately 600,000 acres extending from Monticello 26 miles south to Blanding and 6 miles north to Peter's Hill and stretching from the Blue Mountains east 30 miles to the Colorado line. One-fourth to one-third of this area is covered with timber consisting mainly of pinion pine, oak brush, and juniper commonly called cedar. Both the juniper and pinion are of value as fuel and building material, and the juniper has an additional value for fence posts. While small areas have been cleared of timber …


Bulletin No. 227 - Soft-Curd Milk, R. L. Hill Jun 1931

Bulletin No. 227 - Soft-Curd Milk, R. L. Hill

UAES Bulletins

Data on the early studies on the curd character of milk are found in Utah Agricultural Experiment Station Bulletin 207 and, therefore, are not included here. The key to research in this field came to light with the development of the "Hill Test," the results of which were first published in 1923. This test furnished a means of quantitatively measuring the difference in curd character of various milks.

The term "soft-curd" milk originated with R. L. Hill to describe milk which on coagulation with pepsin or rennin forms a curd that is soft and clabbery in consistency, differing widely from …


Microsporogenesis In Lilium Formosum, Marcella Alice Zeman Jun 1931

Microsporogenesis In Lilium Formosum, Marcella Alice Zeman

Bachelors’ Theses

Anthers of Lilium formosum were collected ranging from the very young to the mature. Anthers used for the writing of this paper were gathered around Easter time or early April. The anthers were removed from the bud and the ends were cut off. Each anther was cut into three or four parts at right angles to their respective lengths. After the washing, infiltration, and imbedding was completed, sections were cut from eight to ten micra in thickness. Before staining the sections were placed in a solution of hydrogen peroxide to bleach for three hours. Flemming 's triple stain, a combination …


The Rise And Development Of The Megagametophyte In Fritillaria Pudica And Fritillaria Atropurpurea, A Thesis Submitted To The Department Of Botany And The Graduate Council Of The Brigham Young University In Partial Fulfillment Of The Requirements For The Degree Of Master Of Science, Bertrand Fereday Harrison May 1931

The Rise And Development Of The Megagametophyte In Fritillaria Pudica And Fritillaria Atropurpurea, A Thesis Submitted To The Department Of Botany And The Graduate Council Of The Brigham Young University In Partial Fulfillment Of The Requirements For The Degree Of Master Of Science, Bertrand Fereday Harrison

Theses and Dissertations

The purpose of this thesis is to present the results of a morphological investigation of the megagametophytes of two species of Fritillaria. The author has attempted to present the data in sufficient detail to clearly picture the significant features in the histories of this gametophyte generation without unnecessary repetition. The data are presented as their chronological sequence dictates.


Circular No. 93 - Better Sugar-Beet Culture For Utah, George Stewart, D. W. Pittman Apr 1931

Circular No. 93 - Better Sugar-Beet Culture For Utah, George Stewart, D. W. Pittman

UAES Circulars

Utah was one of the first states to begin sugar-beet growing. The industry grew rapidly, favored by the climate, by the naturally productive soils, by the freedom from pests, and by the system of intensive irrigation agriculture. California and Utah were among the leading beet-producing states at the time of the World War, and under the stimulus of high prices they remained so until the great depression of 1920. After that, the frequent occurrence of curly-top and the rapid spread of nematode, together with the low price resulting from increased cane sugar production in the tropics and from other causes …


Bulletin No. 225 - Progress Report: Carbon County Experimental Farm, 1927-30, Inclusive, I. D. Zobell, George Stewart Apr 1931

Bulletin No. 225 - Progress Report: Carbon County Experimental Farm, 1927-30, Inclusive, I. D. Zobell, George Stewart

UAES Bulletins

The agricultural problems of the Carbon County Experimental Farm and of the locality which it serves are distinctly different from those of most of the farming localities of Utah. The low and uncertain winter rainfall, the comparative "rawness" of the soils, together with their almost infinite stickiness when wet, and the presence of considerable alkali throughout their body makes them peculiarly sensitive to time and manner of treatment and causes them to absorb water slowly and to erode readily.


Bulletin No. 223 - Feeding Value Of Alfalfa Hay Treated With Calcium Arsenate, H. J. Frederick Dec 1930

Bulletin No. 223 - Feeding Value Of Alfalfa Hay Treated With Calcium Arsenate, H. J. Frederick

UAES Bulletins

For a number of years many tons of sprayed or dusted hay have been fed successfully to livestock by stockmen interested in controlling the alfalfa weevil; nevertheless. the supposed cases of poisoning that have been reported naturally have caused concern among feeders.

Further confusion on this question has resulted from reports on studies designed to determine the effect of lead arsenate instead of calcium arsenate.

Whether the lead in lead arsenate has been a more injurious agent than the arsenic, of course, is difficult to state. Most of the experiments performed in the feeding of sprayed or dusted hay have …


Circular No. 90 - Swine Production In Utah, Harry H. Smith Nov 1930

Circular No. 90 - Swine Production In Utah, Harry H. Smith

UAES Circulars

During the last 20 years there has been a marked change in the type of hogs from the short-legged, wide-bodied or "hot-blood" type to a longer, somewhat more narrow-bodied, "leggier" type. For development of size in hogs they must have (1) length and depth of body, (2) length of leg, and (3) large but not coarse bones. The long-bodied rather "leggy" pig grows rapidly and makes the larger hog. While the modern hog is still a lard hog, it is not as thick and broad as were its predecessors. It is logical to assume that the hog of the future …


Bulletin No. 221 - Snakes Of Utah, Herbert J. Pack Aug 1930

Bulletin No. 221 - Snakes Of Utah, Herbert J. Pack

UAES Bulletins

For 17 years the late Dr. Herbert J. Pack, former Station Entomologist, made a study of the reptiles and amphibians of Utah. His original idea was to publish a comprehensive treatment of the snakes and lizards of his state, and whenever opportunity was afforded collected data on their distribution, habits, and economic importance. At the time of his death, on January 5, 1930, many notes and drawings of lizards were left; a manuscript on snakes, presented for his master's thesis to the Utah State Agricultural College in 1923, was also in his possession. Bulletin 221 contains essentially the information presented …

Underground Plant Development In Its Relation To Grazing, J. E. Weaver Jul 1930

Underground Plant Development In Its Relation To Grazing, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Grasslands or grazing lands are relatively dry lands. Drought, at least in the surface soil, is always imminent. The necessity for the seedling to make immediate and extensive contact with deeper, moister soil is apparent. The water relation is usually controlling, and the success or failure of the seedling largely depends upon its ability to develop an absorbing system adequate in extent and activity to furnish the necessary supply.


Circular No. 86 - Coccidiosis Of Chicken, D. E. Madsen Jun 1930

Circular No. 86 - Coccidiosis Of Chicken, D. E. Madsen

UAES Circulars

Coccidiosis is a highly contagious disease of chickens and other fowls which is widespread and destructive, especially to half-grown chickens. The heaviest losses occur in chicks from 2 to 10 weeks of age. Just prior to and during their first laying season, pullets sometimes become affected with the disease in a chronic form. The cause is a microscopic protozoan parasite, the oocyst form of which is present in the droppings of diseased birds in large numbers. At least three species of the parasite have been recognized in fowls. The severity of the outbreak is thought to be determined by the …


Bulletin No. 217 - Prices Of Farm Products In Utah, W. Preston Thomas Jun 1930

Bulletin No. 217 - Prices Of Farm Products In Utah, W. Preston Thomas

UAES Bulletins

The purpose of this bulletin is to indicate, by means of price data, the relative position of Utah's agriculture, the agriculture of the United states as a whole, and industrial enterprises. It Is the aim to analyze these price data in order to indicate the relationship existing between the various commodities and major enterprises. Through comparative price series an attempt has been made to present in tabular and graphic form a general picture of these enterprises for a series of years.


Bulletin No. 218 - The Alfalfa-Seed Chalcis-Fly In Utah: 1926-29, Inclusive, Charles J. Sorenson Jun 1930

Bulletin No. 218 - The Alfalfa-Seed Chalcis-Fly In Utah: 1926-29, Inclusive, Charles J. Sorenson

UAES Bulletins

During the past 10 or 15 years alfalfa-seed has constituted the major crop in western Millard County and in most of that portion of the Uintah Basin which is situated in Utah. In these sections of the state various natural conditions generally have been favorable for seed production. Within the last five years seed growers have thought that one of the principal limiting factors of the industry has been the alfalfa-seed chalcis-fly. Accordingly, a preliminary survey in the seed districts of the state was made in the fall of 1925 by the Utah Agricultural Experiment Station.

The greater part of …


Circular No. 87 - Raising Dairy Calves, George B. Caine Jun 1930

Circular No. 87 - Raising Dairy Calves, George B. Caine

UAES Circulars

Too much importance cannot be given to the number and kind of calves raised. The life of an average cow is 6.5 years. To maintain the present number of cows in Utah about 15,385 heifer calves should be raised annually. One-half of all calves born are males and are usually disposed of in a few weeks; the other 50 per cent are females from which selection must be made to maintain the herds. In many parts of Utah the number of dairy cows should be increased and probably the best way to accomplish this is to raise carefully selected calves.


Circular No. 85 - Chlorosis Yellowing Of Plants: Cause And Control, F. B. Wann May 1930

Circular No. 85 - Chlorosis Yellowing Of Plants: Cause And Control, F. B. Wann

UAES Circulars

Chlorosis is a disease of plants, the characteristic symptom of which is the yellowing of the leaves. The disease is of sporadic but widespread distribution in Utah and the aggregate losses caused by it are undoubtedly greater than those of any other one disease. Not only are many plants killed, or weakened to such an extent that only inferior crops are produced, but many areas of land which might otherwise support profitable orchards have been abandoned or planted to other crops because of the disease.


Propagation Of Aquatic Game Birds, W. L. Mcatee Jan 1930

Propagation Of Aquatic Game Birds, W. L. Mcatee

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

The propagation of aquatic game birds in the United States is a small but growing industry. Approximately 50,000 wild ducks and 5,000 wild geese constitute the present annual production. Some of these birds are bred by individual or organized sportsmen for their own use, some by fanciers because of their interest in the birds, and others by breeders for sale. The market for two species, the mallard duck and the Canada goose, demands birds for use in restocking, for decoys, and for food. Sale for food is the exception rather than the rule, and is to the better class of …


Homes For Birds, E. R. Kalmbach, W. L. Mcatee Jan 1930

Homes For Birds, E. R. Kalmbach, W. L. Mcatee

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Birds appeal strongly to the interest and affection of mankind. Not only do they charm by their graceful forms, harmonious colors, sprightly actions, and usually pleasing notes, but they have an even more important claim upon our esteem because of their great economic value.

Birds feed upon practically all insect pests. They are voracious, able to move freely from place to place, and exert a steady influence in keeping down the swelling tide of insect life.

For economic as well as for esthetic reasons, therefore, an effort should be made to attract and protect birds and to increase their numbers. …


Circular No. 82 - Lamb Slaughtering And Cutting, Harry H. Smith Nov 1929

Circular No. 82 - Lamb Slaughtering And Cutting, Harry H. Smith

UAES Circulars

The old saying that "the shoemaker's wife goes without shoes" might be changed to read "the lamb raiser and feeder of the west does not eat lamb." About three-fourths of the population of the United states is east of the Mississippi River, and about 90 per cent of all the lamb and mutton produced in the United states is consumed east of the Mississippi. It has been observed, both on the farms and in towns, that a large percentage of people in the sheep sections of the west have tasted neither lamb nor mutton.


Circular No. 81 - Beef Slaughtering, Cutting, And Curing, Harry H. Smith Nov 1929

Circular No. 81 - Beef Slaughtering, Cutting, And Curing, Harry H. Smith

UAES Circulars

Many farmers follow the practice of occasionally slaughtering a steer, a heifer, or a calf for home use. When this practice is followed the farmer is assured of getting meat of high quality. Experience has taught him that he is not always :able to get meat at a local market which equals in quality that which he slaughters on his own farm. The butcher is not at fault as he usually handles the quality of meat his customers desire and will accept.


Circular No. 80 - Domestic Slaughtering, Cutting, And Curing Of Pork, Harry H. Smith Oct 1929

Circular No. 80 - Domestic Slaughtering, Cutting, And Curing Of Pork, Harry H. Smith

UAES Circulars

The practice of slaughtering hogs on the farm is being followed rather extensively by the farmers of this state. It is an economic practice and should be more generally followed because by this practice a supply of meat is available throughout the year. In all ages meat has been the principal article of diet of the ruling races. It is a natural and necessary part of man's diet. The races of people who have not included meat in their diet are today numbered among the weaker and more backward nations.

Bulletin No. 212 - Studies On The Morphology Of The Beet Leafhopper, G. F. Knowlton Jul 1929

Bulletin No. 212 - Studies On The Morphology Of The Beet Leafhopper, G. F. Knowlton

UAES Bulletins

The beet leafhopper, Eutettix tenellus (Baker), is one of the most serious insect pests of western North America. Its chief importance is as a vector of the plant disease curly-top, which it transmits to beets, tomatoes, beans, melons, and many other agricultural plants. The virus apparently is introduced into the plant during the process of feeding, and is responsible for the frequent and often enormous losses to the sugar-beet growers and sugar manufacturers of the west. Apparently, the virus multiplies and remains active in the body of a leafhopper for some time, making it possible for the insect, after once …


Bulletin No. 213 - Food Habits Of Utah Farm Families, Almeda Perry Brown Jul 1929

Bulletin No. 213 - Food Habits Of Utah Farm Families, Almeda Perry Brown

UAES Bulletins

This report is merely an attempt to set forth the findings of the investigation without making claim to their being conclusive except for the families included in the study. While the study was carried into a relatively large portion of the state, the records are too few in number for any claim to be made that they represent community food conditions. It is believed, however, that the records which form the basis of this report are representative of the food situation in the homes from which they come.
