A Study Of The Native Trees Of Amador County, Guy V. Towsley

University of the Pacific Theses and Dissertations

The region covered by this study reaches from the valley floor of the San Joaquin-Sacramento Valley, with an altitude of about 150 feet, to the top of the Sierra Nevada Mountains, whose peaks, in Amador County, reach to more than 9000 feet. Mokelumne Peak has an altitude of 9371 feet. The north and south distance, across the county at Ione, is 22 miles, while at Cook's Station, it is barely 5 miles. Amador County has an area of about 600 square miles.

Thus, a study of trees in this county, gives a fairly representative cross-section picture of the Sierras at …

Ichthyc Oil, John A. Riddick

Field and Laboratory

In the vicinity of Seefeld, in the Austrian Tyrol at an altitude of 1,000 meters lies a rock formation known geologically as Seefeld shale. It is found in veins varying in thick ness from 20 cm. to 100 cm. Enveloping this shale is the Gall enstein formation containing many fossil gastropods. The occurrence of this particular mollusk in large quantities dates the formation as Silurian. The Seefeld formation is a specific bituminous shale which yields a crude oil from which Ichtyhol is made. Centuries ago, the Tyrolian peasants would collect this shale, boil it with water in large pots, and …

A Century Of Scientific Exploration In Texas Part 1: 1820-1880, S. W. Geiser

Field and Laboratory

Science evolves and is perfected by the patient and criti cal labors of generations of investigators; and scientific progress is marked by an unending series of publications. To this fact, indeed, is due the perennial interest of the History of Science…. Texas has an almost unique place in the history of scientific exploration. This is probably owing to a number of singular coincidences.

Bulletin No. 270 - Soil-Management And Crop-Production Studies, I. D. Zobell

UAES Bulletins

Carbon County is the greatest bituminous coal-producing district in the state and ranks as one of the largest and best in the Intermountain West. In 1934 there were twenty-six operating coal mines from which approximately 5,000,000 tons of coal were mined each year. These mines create work for hundreds of men. Many people in this section farm in the summer and mine during the winter months. In 1934 but 20,000 acres of land in this section were under cultivation, with little possibility of reclaiming additional land. Prior to 1928 crops had been somewhat restricted on account of the limited water-supply; …

Relative Efficiency Of Roots And Tops Of Plants In Protecting . The Soil From Erosion, Joseph Kramer, J. E. Weaver

Papers of John E. Weaver (1884–1956)

An increasing realization of the importance of preventing or controlling soil erosion has resulted in numerous scientific investigations. Some of these are concerned with soil characteristics which promote or retard erosivity (Middleton, '30; Middleton et al., '34; Lutz, '34; and Bouyoucos, '35). Many have to do with engineering methods of reducing soil wastage (Bates and Zeasman, '30; Ramser, '30; Roe, '33; and Bartel, '35). But perhaps most were planned to discover the effects of plants in protecting and binding the soil, reducing runoff, and consequent loss of soil and subsoil (Sampson and Weyl, '18; Duley and Miller, '23; Lowdermilk, …

Bulletin No. 259 - Drainage Of Land Overlying An Artesian Groudwater Reservoir: Final Report, O. W. Israelsen, W. W. Mclaughlin

UAES Bulletins

This bulletin constitutes a final report of some phases of cooperative drainage studies in Cache Valley, Utah. The drainage problem in Cache Valley is typical, in many respects, of drainage problems in other irrigated valleys of Utah and the West in general. Application of the principles indicated by the problems will doubtless add materially to the productivity of the land in the several communities concerned and will also contribute to the advancement of public welfare in the general improvement of health, economic, and social conditions. Alkali and water-logging affecting large areas are causes not only of low productivity of the …

Gypsum - Its Value To Texas, May L. Whitsitt

Field and Laboratory

"Gyp" water is for many people the only means of acquaintance with gypsum. A grayish deposit in the tea­ kettle and the difficulties encountered when "gyp" water is used for laundering do not serve as a fitting introduction to the beautiful alabaster of the Taj Mahal. For alabaster is gypsum, too. There are still other forms of gypsum which are making this mineral increasingly important.

Relative Efficiency Of Roots And Tops Of Plants In Protecting The Soil From Erosion, J. E. Weaver

Department of Agronomy and Horticulture: Faculty Publications

Plant cover, soil and topography are the major factors concerned in the problem of erosion. During the earlier studies, conducted largely by engineers, chief emphasis was placed upon topography. Following extensive work by pedologists, it is now generally conceded that type of soil is an equally important factor. Intensive studies on the effect of plant cover reveal the extremely important role played by plants in holding the soil against the forces of erosion. In this preliminary account of the relative effectiveness of roots as compared to tops in holding the soil in place, the results are based on extensive experiments …

The Vitamin A Content Of Sour Cream Butter, Sweet Cream Butter, And Margarines, I. L. Hathaway, H. P. Davis

Nebraska Agricultural Experiment Station: Historical Research Bulletins

Nineteen samples of margarine were obtained from Illinois, Ohio and Nebraska. They were analyzed chemically and the vitamin A content of each one was compared with that of either sour-cream or sweet-cream butter. The fat content of the butter samples varied from 80.2 to 81.5 per cent, while the fat content of the margarine samples varied from 78 .3 to 89.2 per cent. From the results it was evident that these samples of margarine were very poor sources of vitamin A when compared with butter. One of the margarine samples caused an average gain of 10 grams per rat and …

Comparison Of Runoff And Erosion In Prairie, Pasture, And Cultivated Land, J. E. Weaver, Wm. C. Noll

Papers of John E. Weaver (1884–1956)

Soil erosion resulting from runoff water has come to be recognized as a national menace. The determination and evaluation of all factors influencing runoff and erosion are studies of fundamental importance, especially insofar as they may be made to yield information upon methods of control over this insidious tendency of washing away the land.

"Fully 75 per cent of the crop-producing and grazing areas of the United States is sloping enough to set in motion, moderately or violently, these wasteful processes of accelerated soil-removal and excessive runoff. That 35 million acres of formerly cultivated land have been essentially ruined by …

Quantity Of Living Plant Materials In Prairie Soils In Relation To Run-Off And Soil Erosion, J. E. Weaver, George W. Harmon

Papers of John E. Weaver (1884–1956)

The menace of soil erosion did not appear in the west until much of the prairie was broken for cropping or weakened by continuous overgrazing. The grassland sod is a great conserver of rainfall; the amount of run-off water is relatively small, and the soil is firmly held against the forces of erosion. This study is concerned with the role that the living underground plant parts play in promoting the absorption of water by the soil, and especially their importance in reducing run-off. Their holding of the soil against the forces of water erosion has been experimentally determined. A study …

Notes On The Owls Found In Lincoln County, Nebraska, Wilson Tout

Papers in Ornithology

During more than a quarter of a century I have been making notes and collecting information about the Owls of Lincoln county and it seemed an opportune time to put this information into print that it might be available to those who are interested in birds and serve as a basis for further study and amplification. Lincoln County is not usually considered a favorable place for Owls to reside on account of the absence of heavy timber over most of its area. But the nine varieties listed will probably be extended as more observations are made by those who are …
