SULPHUR SPRINGS. 275

The springs were long known locally as Chittenden Sulphur Springs,
but were not improved until 1909, when concrete basins were con-
structed around the springs and the property opened to the public
as Shale Sulphur Springs. Later the name was changed to El Pajaro.
The following analyses of water from the Railroad Spring and the
larger of the White Sulphur Springs show them to be secondary
alkaline, primary saline waters:

The first two samples were analyzed several weeks after they were
collected. In order to determine, if possible, to what extent change
had taken place in the unstable sulphur compounds between the
times of collection and analysis, a sample from the White Sulphur
Spring was later collected in a bottle containing iodine solution, so
that the sulphide constituent was at once precipitated as sulphur
according to the reaction H2S + 21 = 2HI + S and could be determined
independently of the sulphate radicle. The sulphide and sulphate
constituents were then determined within a few days of the time of
collection, with the results shown in the analysis by F. M. Eaton.
These results are not very satisfactory, however, for although the
