Bull. 9.
2. Main spring, Shaffer Hot Springs. Analyst. G. E. Colby (1909). Authority, owner of springs.
3. Honey Lake. Analyst and authority, F. M. Eaton (1909). Sample collected 75 yards from north-
east shore, where water was 18 inches deep.
Dana1 has made aclose examination of the calcareous tufa deposited
in the basin of Lake Lahontan. Three varieties are recognized,
which differ chiefly in physical characteristics. The variety at
Shaffer Hot Springs, which assumes mushroom shapes, is much the
commonest and is known as dendritic tufa. An analysis of the ma-
terial is here reproduced, because, though not strictly a hot spring
deposit, the crags near Shaffer Hot Springs are evidently closely
related to the presence of the hot water.
