warehouse, which is in the ravine 100 yards below Deadshot Spring,
issues through a pipe that has been set into the bank, and yields
perhaps 3 gallons a minute of cool, fresh water that is used for a
table supply at the hotel.
The rocks of this locality seem to be the older sediments and
associated metamorphics that compose the coastal ranges. Witter
Hotel stands on shale and sandstone, and the usual more siliceous
rocks that accompany these sediments are exposed eastward on the
hillsides. Deadshot Spring emerges from a dark siliceous phase
of the sandstone. About 30 yards southwest of the hotel, however,
a ledge of serpentinous rock outcrops, and crosses the creek between
the Iron Tonic and Magnesia springs. It forms the boundary between
a small valley above it and the steep, narrow rapine below. Its
relation to the Deadshot Spring and probably also to the Magnesia
Spring suggests that it is the source of their unusually high magnesium
contents.
SARATOGA SPRINGS (LAKE 18).
Saratoga Springs are on the side of a wide, brushy drainage ravine
about 2 miles in a direct line southeast.of Witter Medical Springs.
The property has been a resort since the seventies, and in 1910,
accommodations for 250 people were provided by a hotel, annex,
and 16 cottages, in an oak grove in a small flat along the creek.
There are 12 small mineral springs on this property, 11 of them being
on the slopes 100 to 150 yards east of the hotel. Six of these rise in
cemented basins in a circular building 15 feet in diameter, known as
the Roundhouse. They have been given such descriptive names as
Appetizer and Digester. All are carbonated and deposit small
amounts of calcium and iron, but they probably differ somewhat
in the relative proportions of the solids in solution. Their combined
flow is perhaps \\ gallons a minute. Ten yards southwestward
there are two other similar springs, and 20 yards to the west there is
one known as the Magnesia Spring. The water of the Magnesia
Spring is less noticeably carbonated than that of the others, but it
has a ferruginous taste and deposits considerable iron in its basin.
About 50 yards south of the Roundhouse there is also a carbonated
iron spring whose water deposits notable amounts of iron. In the
bank near it there is a small exposure of lime carbonate and of iron-
stained ocherous earth. All of the 10 springs thus far mentioned
rise in cemented basins at the bases of small banks that expose
crushed shale and sandstone. Their discharge is collected in a tank
and supplies water for bathing. About 75 yards north of the Round-
house a sulphur spring issues at the base of a bank of dark crushed
shale. It yields peihaps 1 gallon a minute of strongly sulphureted
water and because of its presence the locality is shown on Plate III
