These two waters are of about equal concentration and both are
primary in character. However, primary salinity is the dominant
property in the Radium Sulphur Spring, whereas primary alkalinity
predominates in the Bimini Hot Spring. The addition of calcium and
magnesium sulphates to Bimini spring water would change its char-
acter to approximately that of the Radium Sulphur Spring.
The well at the Radium Sulphur Spring was drilled to a depth
of 1,000 feet or more in the oil formation. A strong flow of water
was encountered, which was with difficulty shut oft", but several years
prior to 1908 the well ceased to flow.

PASO ROBLES HOT SPRINGS (SAN LOTS OBISPO 2).
Thermal waters issue at a number of places near Paso Robles, in
the upper portion of Salinas Valley. As early as 1865 a warm sul-
phureted spring in the southern part of the town was improved for
bathing, the spring being cemented and covered by a large masonry
dome, and a swimming plunge being constructed. Another spring
near by was also inclosed by masonry walls and made use of for bath-
ing. These springs have been abandoned for several years, however,
apparently because they have nearly or entirely ceased to flow.
Hotel El Paso de Robles was built about 1888. It is situated in
the western part of town, within extensive grounds that also inclose
