The purpose of this investigation was to determine the nature of the extractives from red alder bark in an effort to discover the materials which cause the red stain in red alder wood. Samples of bark and wood were obtained and successively extracted with hexane, benzene, ether, ethanol, and hot...
Fisheries Laboratory during 1952, in the rearing of the native Pacific Coast oyster, Ostrea lurida Carp., in small containers. The decline of the oyster fishery in Yaquina Bay, Oregon, has been attributed in part to the lack of adequate spat-falls. Investigations were begun in 1947 to devise methods of artificially...
An investigation of the fishes of the Willamette River and three of its larger tributaries was made during July, August, September, and November of 1951, to ascertain the possibility of using them as bio-indices of pollution. Thirteen stations were established on the Willamette River and tributaries. These stations were selected...
The purpose of this thesis was to evaluate two methods of estimating 1953 costs of producing strawberries. To accomplish this the following steps were taken: 1. To estimate production costs in 1953 by using 1947 input data and 1953 prices for those inputs, (Method 1); 2. To compare the results...
Turkey is an agricultural country where exchange and shipping of goods has been gravely hampered in the past by lack of highways. The railroads have large expanses of land between them, and highway construction in the past has been limited to strategic roads and connections of cities to railways. Unless...
This thesis presents the information collected on various phases of the life history of the sage grouse in the Hart Mountain area of southeastern Oregon during the period of April 8 to September 12, l954. The material was gathered in an attempt to compile information on reproduction, survival, and other...
History, topography, and nature of people have influenced the development of electric power in Greece quite substantially. The power production per capita in Greece is very low as a result mainly of continual wars and an uneven distribution of population. In 1948, electricity was being supplied in the country only...
More than one-fourth of the forest land in the Pacific Northwest is growing timber at reduced capacity as the result of brush encroachment. Increasing use of chemicals in brush control requires that more information be available regarding their use. Bigleaf maple, Oregon oak and vine maple are among the more...
The objective of this study was to estimate the bulk densities and points on the moisture-tension curves and to determine their associated variances for some of the selected mapping units in Central Oregon. These variances will produce informations concerning the precision of the mean and the optimum sampling schemes, for...

identified as Ephedra viridis Coville is reported of medicinal
value among the American Indian tribes and other
dwellers of that locality in various affections such as
venereal diseases, kidney and bladder disturbances, in
stomach ulcers and abdominal pains, in delayed menstruation,

The purpose of this thesis is to outline the principles involved in the reconnaissance, survey, and design of forest roads in the Douglas-fir Region. The reconnaissance survey is the most important element in road location. Poor reconnaissance often results in abandonment of the route at considerable expense. The ground slope...
The Oregon State Cooperative Seed laboratory uses two methods for testing the quality of Douglas-fir seed lots. The first of these is a straight-forward germination test without any pre-treatment of the seed, involving a period of 42 days in the germinator at alternating 20°C.-30°C. temperatures. The second method consists of...
A study was undertaken to account for and authenticate all mortality factors
affecting pronghorn antelope herds in Oregon. Work commenced in June, l954, and
terminated in July, 1956. Information pertaining to antelope mortality in other
states was also collected for comparison with Oregon conditions. Mortality factors
investigated and their importance...
Two soils representative of the coast and three representing the Willamette Valley have been studied for their general chemical
characteristics. Exchange capacity and exchangeable cations were
determined by the ammonium acetate and the BaCl₂-triethanolamine
buffer methods. Exchange capacity was also obtained from conductimetric
titrations which were run on each soil...
Scandinavian textiles have played an important part in the family life of the Nordic people. During the evenings, members of a family worked on textiles and wove colors and designs of the countryside and of the family life into their fabrics. Traditional motifs, techniques, and color combinations were developed and...
There are approximately 4,000,000 acres of cut-over and burned-over land in western Washington and Oregon which are either non-stocked or unsatisfactorily stocked with young forest growth. This brings about a great need for a quick and efficient method of land examination from which to plan reforestation measures and make up...
A taxonomic and ecologic study was made of the
vascular plants of a section of the Owyhee River Canyon
of Malheur County, Oregon. The particular study area is
known as Three Forks, and is located at the junction of
the North Fork of the Owyhee River, East Fork of the...
