Applying the correction factor of 1.44 to the 1927 silica values, it is found that
the silica content of the various streams ranged from 1.4 to 5.0 milligrams per liter.
In 1935, the silica values ranged from 5.0 to 13.0, and in 1936 they ranged from 4.0 to
15.0 milligrams per liter. In both 1935 and 1936, it was noted that the silica content
of the wa.ter of any one stream varied with the stream flow. In the summer months
of 1927 there was 1.6 times as much precipitation as during the same period in 1935,
and 3.4 times аз much ав in 1936; hence, the stream flow iu 1927 must have been con-
