a number of small volcanic craters, and the surface is partly covered
with fragments of pumice and obsidian. At the vapor vents the rock
has been extensively altered by solfataric action and reduced to a
siliceous sinter, but a mud similar to that at the Coso Springs was not
observed. This difference is probably due partly to the fact that
there is not sufficient water at the vapor vents to form a mud, and
partly because they issue through lava, which does not become kaolin-
ized as readily as does the granitic rock at Coso Hot Springs.

SUMMARY OF HOT SPRINGS.
The foregoing descriptions, comprising 149 springs or groups of
springs, include 9 resorts at which there are no natural springs, so
that the total number of hot-spring groups is 140. As several springs
that have been described separately may be considered geographically
to form only one group they have been gathered in the following list
into 98 general localities, which have been arranged (1) according to
the absence or presence of a notable spring deposit; (2) according to
the absence or presence of lava near by, and (3) according to the char-
acter of the material from which the water issues, this arrangement
having been adopted in order to show clearly the formation of depos-
its by hot springs, the relation of hot waters to lava areas, and their
general geologic features.
