counted only 18 appreciable springs. Spring houses protect the
three that are most used for drinking. Water from another spring
supplies the evaporating trays. Two other springs rise in cemented
reservoirs about 15 and 20 feet in diameter. Gas from one of these,
which is called the Natural Gas Spring, is piped to a tank higher
on the hillside for use at the hotel, and water from the other, which
is named Fountain Spring, supplies the baths. The other springs
rise in bricked and cemented basins along the banks of the drainage
channels. All of the springs are within 250 yards south to east of
the hotel, which is on higher ground overlooking them. Most of
them are of inappreciable flow, but all are strongly mineralized.
Some are strongly sulphureted as well as saline., and for this reason
the locality is marked on Plate III (in pocket) as one of sulphur springs.
The following analyses indicate that they are primary saline waters
remarkably uniform in composition for springs of such high mineral
content, the chief difference being in the high sulphate content of
spring No. 1. The remarkably high potassium content in all but
the Natural Gas Spring is notable. It is not unlikely that the pro-
portion of potassium is about the same for all the springs and that
the apparent difference is due to differences in analytical methods
or calculation.
