CARBONATED SPRINGS. 157
as 1878 the locality was resorted to for use of this water. In
1887 it was put on the market for table use, and since that time
the property has been extensively improved. There are extensive
grounds in which are grouped .several cottages, clubhouse, recep-
tion hall, and dining hall; and a bathhouse and a swimming plunge
have been erected beside the creek. The place is within an easy ride
from St. Helena by automobile stage, over a graveled and well-
graded road.
The Tunnel Spring is no longer used, but on the southern bank
of the creek two similar springs, known as the Summerhouse and the
American Ems, have been surrounded by cemented basins and pro-
tected by a spring house. The two springs that furnish the water
for bottling are situated in open land about 700 and 800 yards,
respectively, northeast of those at the creek, at places that were
formerly tule grown. The more distant is known as the Potassium
Spring and is the one whose water is chiefly bottled; the other is
called I-ador-a Spring.
The water of all five of the springs now used is carbonated, tastes
distinctly mineralized, and is noticeably thermal, but as they are best
known for their carbonated character they are more properly described
under this heading. Summerhouse and American Ems springs are the
warmest, their recorded temperature in 1909 being 92°. Analyses
of all the springs, including the Tunnel Spring, have been made,
and are here reproduced in standard form.
