214 SPRINGS OP CALIFORNIA.
Congress and Azule springs form a rather isolated group of car-
bonated springs, for'springs of this character are not common in this
part of the Coast Ranges. There was formerly a carbonated spring
about 200 yards east of the reduction works at the New Almaden
quicksilver mine, 15 miles southward from San Jose, but the crevice
or other source from which it received its carbon dioxide was cut
through by mining operations, and the spring has been dry for many
years. During the seventies its water was bottled and marketed as
New Almaden Vichy Water, and in later years it was also pumped
for bottling. An approximate analysis 1 showed that it contained
considerable sodium, calcium, bicarbonate, sulphate, and free carbon
dioxide.
MADRONE SPRING (SANTA CLARA 8).
Madrone Spring is situated on a tributary to. Coyote Creek, 14
miles east of Madrone station. There were several cottages and a
small hotel on the property as early as 1880, and in 1891 a larger
hotel was erected. In 1908 the place was conducted mainly as a
hunters' resort, with accommodations for about 50 people. A trail
leads southeastward over the hills 6 miles to Gilroy Hot Springs.
The spring issues at the southern edge of the stream channel,
beside a dancing pavilion that has been built over the creek. When
visited the water issued in a cemented basin that had no appreciable
overflow and was lifted to the level of the pavilion by a hand pump.
In 1892, and for a few years following, the water was taken in barrels
to San Jose and bottled. The analysis tabulated on page 215 shows
that the water is essentially primary and secondary alkaline.
On the slopes south of the hotel are two unused seepages that are
called "arsenic" and "iron" springs but do not appear to be notably
mineralized. A quarter of a mile westward, up the creek, a faintly
sulphureted spring that yields about one-half gallon a minute issues
at the southern edge of the stream; it has been protected by a box
curbing that forms a small drinking basin.
The carbonated spring rises from dark-colored shale which is ex-
posed along the creek for 50 or 75 yards above and below it. A little
farther downstream, thick-bedded sandstone is exposed, and eastward
from it, the sediments are siliceous and cherty. The series dips
nearly vertically northeast and strikes northwestward across the
creek.
GOES SPRING (SANTA CLARA 7).
In a ravine about 1J miles west of Madrone Spring, on the Coe
ranch, carbonated water rises in a stream channel, amid bowlders of
sandstone, and in 1908 a pipe conducted it from a small basin in the
