The protozoan diseases of hatchery fish

Following the somewhat bleak picture painted in the consideration of the bacterial diseases of hatchery fish in the last number of The Progressive Fish Culturist, it is a relief to turn to another large group of fish diseases caused by small, single-celled parasitic animals known as the protozoa. To the hatcheryman, the protozoan diseases of fish are just as important as the bacterial diseases for

Water utilization in the Snake River Basin

The purpose of this report is to describe the present utilization of the water in the Snake River Basin with special reference to irrigation and power and to present essential facts concerning possible future utilization. No detailed plan of development is suggested. An attempt has been made, however, to discuss features that should be taken into account in the formulation of a definite plan of de

Zinc and lead ores occur in the northern counties of Arkansas, from the Arkansas-Oklahoma line on the west to the Coastal Plain, in Lawrence County, on the east, but are concentrated chiefly in Marion, Boone, Newton, Searcy, Sharp, and Lawrence Counties.  Lead ore was reported in the region as early as 1818, and small reduction plants were built in the vicinity of Lead Hill in 1851 or 1852.  The C

Field evidence about the viscosity of lavas

There appears to be surprisingly little definite information on the viscosity of lavas. With few exceptions writers content themselves with such general and indefinite terms as “mobile”, “viscous”, or “highly viscous”. Apparently the only attempts to actually calculate viscosity have been made on Hawaiian lavas. G. F. Beoker (Some queries on rook differentiation, Amer. J. Sci., 4th ser., v. 3, pp.

The Rôle of volatiles in the formation of Virginia titanium deposits

The feldspathic rock with which the titanium deposits of Virginia are associated appears to be an anorthosite, although the plagioclase is somewhat more sodic than in normal anorthosites. That is, this rock shows evidence of having been introduced as a mush‐like mass of crystals and intersititial magma, and of undergoing very thorough crushing during introduction. This rook was later very thorough

Relation of stream‐flow to ground‐water levels

In recent years the Water Resources Branch of the United States Geological Surrey has given considerable attention to the relation of ground‐water to stream‐flow. One locality in which this relation is being studied is about 13 miles from Washington, near Colesvllle, Maryland, where a Kinnison float‐gage is being maintained in a well In connection with the operation of a gaging‐station on the Nort
