Age, growth, and maturity of the longnose sucker Catostomus catostomus, of western Lake Superior
Merryll M. Bailey
1969, Journal of the Fisheries Research Board of Canada (26) 1289-1299
Studies of age, growth, and maturity were based on 1760 fish collected in western Lake Superior in 1964-65. The body:scale relation was curvilinear and the curve had an intercept of 1.65 inches on the length axis. The weight increased as the 2.85 power of the length. Some fish formed an...
Maturity and fecundity of walleyes from the eastern and western basins of Lake Erie
David R. Wolfert
1969, Journal of the Fisheries Research Board of Canada (26) 1877-1888
Of 2427 walleyes (Stizostedion vitreum vitreum (Mitchill)) examined from Lake Erie in 1964–66, no females were mature at ages below III and all were mature at age V. All male walleyes from the eastern basin were mature at age II, and those from the western basin at age III. Females from...
Saline water in southeastern New Mexico
W. L. Hiss, J.B. Peterson, T.R. Ramsey
1969, Chemical Geology (4) 341-360
Saline waters from formations of several geologic ages are being studied in a seven-county area in southeastern New Mexico and western Texas, where more than 30,000 oil and gas tests have been drilled in the past 40 years. This area of 7,500 sq. miles, which is stratigraphically complex, includes...

The determination of the acoustic parameters of volcanic rocks from compressional velocity measurements
R. D. Carroll
1969, International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts (6) 557-579
A statistical analysis was made of the relationship of various acoustic parameters of volcanic rocks to compressional wave velocities for data obtained in a volcanic region in Nevada. Some additional samples, chiefly granitic rocks, were also included in the study to extend the range of parameters and the variety of...
Geochemical maps of an area northwest of the Chulitna River, central Alaska Range
C. C. Hawley, Allen L. Clark
1969, Open-File Report 69-123
An area northwest of the Chulitna River in west-central Alaska Range locally shows local anomalous concentrations of gold, silver, arsenic, copper, zinc, and lead in stream-sediment samples. Most stream sediments showing anomalous concentrations of metals can be correlated with either known or newly discovered deposits or occurrences described in Circular...

Aging small Canada geese by neck plumage
K.F. Higgins, L.J. Schoonover
1969, Journal of Wildlife Management (33) 212-214
The neck plumage method, a new technique for separating immature from adult Canada geese (Branta canadensis) in the hand, was evaluated by comparison with the notched tail feather and cloacal examination methods. Two (1.4 percent) of 141 geese examined were misaged, resulting in a 6 percent error in the immature-adult...

Cliftonite: A proposed origin, and its bearing on the origin of diamonds in meteorites
R. Brett, G.T. Higgins
1969, Geochimica et Cosmochimica Acta (33)
Cliftonite, a polycrystalline aggregate of graphite with spherulitic structure and cubic morphology, is known in 14 meteorites. Some workers have considered it to be a pseudomorph after diamond, and have used the proposed diamond ancestry as evidence of a meteoritic parent body of at least lunar dimensions. Careful examination of...

Rapid determination of filterable residue in natural waters
Herbert E. Allen, Charles W. Bacon
1969, Journal - American Water Works Association (61) 355-356
The most widely used procedures for determining filterable residue (total dissolved solids) in water are macromethods given in Standard Methods. Although macromethods give good results, they require large amounts of water and long drying times. This report describes a microtechnique for determining filterable residue that requires only 0.05...
