A method is described to determine the distribution of the bending stresses in a wood beam when some of these stresses exceed the proportional limit. This is used to calculate the position of the neutral axis and the bending strength of some Douglas-fir beams. The calculated values agreed with the...
An anemia of juvenile chinook salmon (Oncorhynchus tshawytscha) is described and stages of development separated by recognizable syndromes. A vitamin E-deficient diet of low rancidity produced a severe microcytic anemia with strong immature red cell response and granulocytosis occurring 2 to 4 weeks before a drop in hemoglobin and hematocrit...
Part I. To aid in the management of the Tillamook Bay commercial salmon fishery, a tagging program was conducted on the salmon and steelhead trout runs in 1953. General migration behavior, the minimum length of time the fish remained in the fishery, population sizes, and fishing mortalities were determined from...
Clatsop Beaches, characterized by flat beach-face slope (1:70) and small sandsize (0.2 mm.), have supported commercial and recreational fisheries for the razor clam (Siliqua patula) for many years. Tracing the linear growth of two year classes through more than one year following set led to a validation of the ring...
The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...
ENTOMOLOGISTS, BOTANISTS, and AGRICULTURISTS all
have occasion to concern themselves with bees. The en-tomologist is fascinated by their complex behavior pat-terns, the botanist needs to evaluate their significance infloral biology, and the agriculturist must take them into account as vital factors in crop production. Finally, the apiculturist often wishes to...

The mapped area is part of the middle Deschutes Basin of central Oregon, which lies in the northwestern corner of the High Lava Plains physiographic province, between the Cascade and Ochoco Mountains. It is underlain by Cenozoic lavas, tuffs and sediments of continental origin. The oldest rocks in the sequence...

This sequence was deposited in the ancestral Deschutes River Valley along the east flank of the Cascade Range during the...
Two intermediate cuttings were made in a Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stand on the Wilark forest management research area in northwestern Oregon. Age of trees in the stand varied from 47 to 62 years at the first cutting. Crawler tractors were used in both extractions. In the first cutting,...
Germination and survival of Douglas-fir on seedbeds of unburned,
lightly burned, and severely burned soil, charcoal, litter, and sawdust,
exposed to 100, 75, and 25 percent of full light, were studied on a
south-facing clearcutting in the Coast range of Oregon.
Irrespective of exposure to light, germination was best on...
Survival and growth during three years at 8 out-planting areas are reported for Douglas-fir from 14 sources of seed. Early survival was highest near Nimpkish on Vancouver Island. At most plantations, trees from the local seed source grew as well as did those from the best three sources. Trees from...
Planting techniques, size and age of seedlings, and protection
against animals were investigated for their influence on survival of
ponderosa pine at two sites in southern Oregon. Caging and mulching
with paper were the most effective measures for reducing mortality.
Preliminary trials prior to large-scale planting were recommended for
determining...
Correlation was sought between abundance of mycorrhizae on
Douglas-fir seedlings and their survival in field plantations.
One possible indication of dormancy desirable for lifting from
nursery beds could be the varying seasonal abundance of ectotrophic
mycorrhizae on roots of seedlings. No direct correlation between percentage
of mycorrhizae and survival in...
The effect of lifting Douglas-fir seedlings from the nursery bed
and replanting them, either immediately or after storage at 2 C for
periods up to six weeks, was investigated through a series of experiments
conducted in controlled-environment chambers and under field
conditions. Seedlings lifted prior to December, or after buds...
An investigation has been made of several physical parameters of the effluent plume of the Columbia River as it enters the Pacific
Ocean. Radioactive material in trace amounts enters the Columbia River from the Hanford nuclear reactors at Richland, Washington. One of these nuclides, chromium -51, has been used to...
The life history of juvenile sockeye salmon (Oncorhynchus nerka) resident in Chignik River, Alaska, represents a departure from the lacustrine, pelagic existence typical of juveniles of this species. For this reason, the distribution, relative abundance in different parts of the river, growth, and upstream and downstream movements of juvenile sockeye...

Bumpus samplers were used and stations ranged from 5-105 miles from shore along four hydrographic lines. Forty-six species of copepods were identified. The total adult population varied according to distance from...
Fifty-two one-meter plankton net samples from four stations off Newport, Oregon, were examined for composition and abundance of euphausiids and copepods. They provided data on dominance, species associations and environmental relationships. The euphausiid-copepod population off Oregon is composed of 12 numerically dominant species. These species occurred in most of the...
Chemical and microbial analyses were made at four seasonal intervals on soil horizons under red alder, conifers, and mixed
