170 SPRINGS OF CALIFORNIA.

CARBONATED SPRINGS ON RUSSIAN RIVER (MENDOCINO 29).
Carbonated water issues from gravel at the western edge of Russian
River, 2| miles north, of Hopland, in springs locally known as Human-
ity Springs. In 1907 an excavation was made at the place so that
the water was accessible, and it was considered to be of medicinal
value. During the summer of 1910 the springs were again rendered
accessible, and some of the water was bottled.
The following analyses represent water from two springs at this
locality that issued a few yards apart in 1907:

ORNBAUNS MINERAL SPRING (MENDOCINO 35).
Ornbauns Mineral Spring is located at the lower end of a small
meadow valley, 20 miles northwest of doverdale. The spring issues
near the southern side of the creek that runs through the meadow
from soft, shaly sandstone that has been exposed by removing the
thin layer of alluvium in order to obtain a rock drinking basin. The
water is moderately carbonated and has noticeably iron stained the
near-by surface.
In the summer of 1909 a hotel of about 20 rooms was built on the
edge of the valley.

CABBONATEB SPRINGS ON GABCIA RIVER (MENDOCINO 34).
About 3J miles southwestward, downstream from Ornbauns spring,
carbonated water seeps from the banks above Garcia River. One
spring of appreciable flow also issues near the water's edge but is
submerged during stormy periods. The springs are accessible by a
trail but are seldom visited. A small alkaline deposit from the water
makes the place a local deer lick. The rock from which the springs
