SULPHUR SPRINGS. 269

PIEDMONT SPRINGS (ALAMEDA 1).
Piedmont Springs are in a recreation park on the hillside 3 miles
north of Oakland.
Two mineralized springs, which are known, respectively, as Sulphur
and Magnesia springs, rise in a ravine that extends through the prop-
erty. The springs have been curbed and covered, and the ravine has
been graded for a walk. The waters are piped about 100 yards
downstream into two drinking basins in a grotto-like spring house
that is built against a rock face at the side of the ravine. A third
basin in the spring house is supplied from the municipal water main.
The water of both springs is noticeably sulphureted, and that of the
Magnesia Spring also tastes distinctly alkaline. The following
analyses show the characters of the waters. Both have noteworthy
primary salinity and secondary alkalinity, but although the sulphur
spring is characterized by secondary salinity, the magnesia spring
has high primary salinity.

The second analysis is given by Anderson 1 as from an "iron
spring," but this is believed to be the same spring that is now known
as the Magnesia Spring.
