OHMS SPRING (SONOMA 21).
About one-half mile southeast of Boyes Hot Springs is another
drilled well whose water was used to some extent in 1909 for bathing.
The property was open to the public under the name of Ohms Spring,
and accommodations were provided for about 20 guests.

AQUA CALIENTE SPRINGS (SONOMA 18).
About 1 mile northwest of Boyes Hotel a similar resort has been
built up at Agua Caliente Springs. A hotel and cottages here pro-
vide for about 300 people. A large swimming plunge and tub baths
are supplied by five flowing wells one-third of a mile southward.
The wells are drilled about 300 feet deep and the reported tempera-
tures of the waters range from 97° to 108°. In 1909 Agua Caliente
water was bottled and marketed, both carbonated and natural, for
table use. The following analyses represent the water from wells at
Agua Caliente Springs and Boyes Hot Springs:
