The quality and chemical composition of the water of a stream may affect its availability for use as a domestic supply, for boilers, manufacturing and other industries and for irrigation. In order to determine the fitness of the state's waters for these various uses, a chemical survey was undertaken by the Geological Survey. Daily samples have been collected at 24

points on 21 rivers in the State for a year, and analyzed in groups of 10 days.

In all 842 separate water analyses have been made in the laboratory at Salem. Of these 808 were for river waters and involved the search in each case for nine or more minerals in solution, in addition to the determination of color, turbidity and total solids.

A report embodying the results of the study will be available some time in 1913.
