side of a branch of Putah Creek, and yield water at temperatures of
90°, 116°, and 120°, at a rate of 1, £, and 8? gallons a minute, respec-
tively. The property has been a resort for many years and the water
of the Iron and Sulphur springs is used in tub and plunge baths.
Buildings have been erected from time to time, so that in 1909 accom-
modations for about 200 people were provided by a hotel, a three-
story rooming house, 8 or 10 cottages, and a dozen tent houses. A
large building containing a gymnasium and dancing floor provides
means for entertainment. The waters of four springs at this place
have been analyzed. One of the springs, which was called the Mag-
nesia Spring, was originally of slight flow and is no longer important,
but the following analyses show the characters of the three others:

The water of the Sulphur Spring appears from the analysis to
be of mixed type and rather high concentration; its most note-
worthy peculiarity is the content of hydrogen sulphide. The
Iron and Arsenic springs are similar in concentration and character,
both possessing marked primary alkalinity as well as primary salinity
and secondary alkalinity. The relatively high proportion of magne-
sium is of interest and, in connection with the relative amounts of
