Distribution Of The Herpetofauna Of Kentucky., Symoine Kamin Laufe
Distribution Of The Herpetofauna Of Kentucky., Symoine Kamin Laufe
Electronic Theses and Dissertations
Although the herpetofauna of Kentucky is extensive and varied. it has received much less attention than that of most other states. Many herpetologists have reported on various phases of the state's amphibians and reptiles, but for the most part these reports are discrete, either pertaining to a collection, or a generic or specific study. Hence, there is no single adequate work which aptly describes the herpetology of Kentucky as a whole. When one realizes the keystone position of Kentucky in relation to northern and southern forms, the need of a zoogeographical summary of the state becomes even more apparent. Therefore, …

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 …
Brief Short-Title List Of Published Works On The History Of Science, Samuel W. Geiser, Bessie T. Geiser
Brief Short-Title List Of Published Works On The History Of Science, Samuel W. Geiser, Bessie T. Geiser
Field and Laboratory
The present brief list was compiled primarily for the use of students in a course on the History of Science offered by the senior author at Southern Methodist University. It is far from complete: scholars conversant with the field will note omission of works they consider of primary importance, and the inclusion of others, to them of secondary interest. We are not sure that in every case our omissions and inclusions are fully defensible; but it is believed that this bibliography includes a very large proportion of the best works on the subject in hand.

Plan Of Development For Valley Gravity Project, Julius A. Krug, Michael W. Straus, Wesley R. Nelson
Lower Rio Grande Valley Curated Material
"The Valley Gravity Project Plan has been formulated to furnish an adequate and dependable irrigation water supply for fertile and productive area in the Lower Rio Grande Valley, Texas, It would also provide drainage works, which would remove the threat of destruction of the economy of the area due to effects of a high water table and salt accumulations. The project works would permit generation of the maximum practicable amount of electrical energy which otherwise would be required to operate irrigation pumping plants. Other incidental benefits include fish and wildlife conservation, recreation and flood control."

Influence Of Food Plants On Fecundity, Larval Development And Abundance Of The Tuber Flea Beetle In Nebraska, Roscoe E. Hill
Influence Of Food Plants On Fecundity, Larval Development And Abundance Of The Tuber Flea Beetle In Nebraska, Roscoe E. Hill
Nebraska Agricultural Experiment Station: Historical Research Bulletins
Laboratory and field tests were conducted to determine the effects of different food plants on fecundity, adult longevity and larval development of the tuber flea beetle, Epitrix tuberis Gentner. All food plants tested were those upon which the overwintered beetles commonly feed in the spring following emergence from hibernation.

Dr. Ernst Kapp, Early Geographer In Texas, S. W. Geiser
Field and Laboratory
Because of its geographic position midway between Mexico and the old Louisiana Purchase, Texas has a fauna and flora that show in many respects transitional forms. The further fact that Texas was for ten years an independent republic, open to free immigration, brought into the new country citizens from diverse European lands, with their old cultures, who mixed with the preponderating immigrants from the United States. As a consequence, Texas came to be known to scientific men the world over as a new and interesting country to be explored…. Among the geographers, the most notable were William Bollaert, Thomas Falconer, …

Collectors Of Pleistocene Vertebrates In Early Texas. I. William P. Huff (1811-86), S. W. Geiser
Field and Laboratory
Much of the ·work of exploration for Pleistocene vertebrates has been done in the last sixty years; but some was done at a period as remote as the first days of the Republic of Texas. William P. Huff, merchant of San Felipe, the summer of 1837 found proboscidean and other remains at the shoals of the Brazos, a few miles below San Felipe. He built up a collection.
Bulletin No. 316 - Marketing Fruits And Vegetables In Utah, W. Preston Thomas, George T. Blanch
Bulletin No. 316 - Marketing Fruits And Vegetables In Utah, W. Preston Thomas, George T. Blanch
UAES Bulletins
During the period from 1920 to 1941 the fruit industry in Utah and other areas or the west went through a period of adjustment. Previous to and during World War I, growers received high prices for fruit which resulted in increased production. However, following the sudden drop in prices of 1920, fruit growers had a hard time to market the large tonnage produced. Returns were low. During this period keen competition for the sale of fruits developed between individual growers and various producing areas. Although the problems of adjustment were severe in most fruit areas of the west, the marketing …

Racer's Storm (1837), With Notes On Other Texas Hurricanes In The Period 1818-1886, S. W. Geiser
Field and Laboratory
Recently, while gathering material on the life of Elijah H. Burritt (early American astronomer and engineer, leader of an emigrant-company to Texas (1837) from New Britain, Conn.) I unearthed many data on our first notable Texas hurricane. The Racer Storm of Sept. 26-Oct. 10, 1837 was on the Texan coast from Oct. 2 to Oct. 6. It was especially destructive at the mouth of the Rio Grande, as also at Galveston Island where a settlement was in process of forming.

William Douglas Wallach, Pioneer Hydrographer Of Texas, S. W. Geiser
Field and Laboratory
A recent issue of the Southwest Review gives an account of some phases of the life of William Douglas Wallach (1812-71), noted editor of the Washington Evening Star (1853-67), and at an earlier period (1838-45) surveyor and newspaper editor in Texas. To an historian of scientific work and exploration in Early Texas, the career of Wallach is of especial interest. Almost the first hydrographic work on inland coast-wise waters of the State was done by Wallach in his survey of part of Matagorda Bay, 1839 (at the request and expense of the Board of Aldermen of Matagorda.

Bulletin No. 304 - Phosphate Reserves Of Utah, J. Stewart Williams, Alvin M. Hanson
UAES Bulletins
To supplement the work reported by the senior author in Bulletin 290 of the Utah Agricultural Experiment Station, the writers have visited the phosphate outcrops in Weber, Morgan and Salt Lake Counties, as well as those in the Park City District of Summit County and others west of Midway in Wasatch County. These areas were found to contain considerable phosphatic shale of 25 to 35 percent grade, but no rock of 40 percent grade, the minimum quality included in the estimates in Bulletin 290. However, the data recorded for the sections visited are valuable in showing the leanness of these …
