SALINE SPRINGS. 295

situated on the sides of the wide drainage channel of San Roque
Creek, about three-quarters of a mile northward from the ocean.
The principal springs are on the western side of the creek, but water
from about 12 springs, half of which are on each slope of the drain-
age channel, has been piped to collecting tanks in a warehouse at
the principal springs. As the yield of the springs is small and the
bottled product consists of the combined flow from a number of springs
whose composition probably varies with the season, differences in
any two analyses of the water would be expected. The remarkably
high content of magnesia shown by the analysis on page 296 seems to
have been produced by concentration of the material from the ocean
water by some means which is not clearly understood but which prob-
ably involved the evaporation of the water of lagoons to a bittern.

BYTHENIA SPRINGS (SANTA BARBARA. 4).
Bythinia Springs issue in a gully on the hillside, half a mile north-
west of Veronica Springs. The water has been piped to a bottling
house below them and marketed as a medicinal water, but the com-
mercial value of the springs has not been so great as that of the
others to the southeast.

SANTA BARBARA SPRINGS (SANTA BARBARA 5).
Santa Barbara Springs are about three-fourths of a mile northeast
of Veronica Springs, near the top of the mesa land overlooking Santa
Barbara. Their water, like that of the other strongly mineralized
springs in the locality, has been marketed to some extent for medi-
cinal use. Pipes from several small springs supply a bottling plant.
The following analyses of waters from the three groups of springs
last described show that they all are primary and secondary saline
waters, secondary salinity being dominant in Veronica and Bythinia
springs.
The flat-topped hills on whose flanks the springs issue are com-
posed of shales of late Tertiary age that probably belong to the
Fernando formation, which has been described by Arnold.1 The
mineralized water is said to seep from a yellow clay of the consist-
ency of cheese.
