the decayed serpentine on nitrates derived from buried organic
material.
About 75 yards eastward downstream a cold, mildly sulphureted
spring, called Milton Spring, issues from a crevice in a ledge of the
schist on the opposite side of the creek and several feet above it.
Water from this spring has been used for drinking. A few yards
farther north there is a small seepage pool of sulphureted ammoniacal
water, which has been used only slightly for drinking and for sham-
pooing. The following analyses represent water from the two
principal springs:

Both springs are essentially primary alkaline and saline in character.
The deficiency in acid radicles commonly found in water is especially
noteworthy. The water of the Milton Spring, though differing in
several particulars from that of the main spring, appears to have
the same origin. It is a water such as would be produced by diluting
water from the main spring with surface water.
There are benches of gravel along the canyon sides for half a mile or
more above and below the springs. Farther down the canyon some
gabbroid rock was noticed, but nearly to Cantara railroad station, 2
miles away, the canyon walls are mainly of light-colored lava,
probably andesitic, which at one place forms prominent cliffs.
