at first in getting the materials to

pipes which conduct tho water up the

tho schooner Parallel went ashore and

motor Vas completely wrecked. A

stone weighing $50 ions fell mi had
to be removed. The motor ia a very
simple contrivancc and still is capable
of excrting a great power.
Across u c,unsm in the rocks just
north of Parallel point a bridge Of
heavy timbcrs was built. Suspended
from this is a huge fan or paddle OF
oak timbcrs. with the spreading por-
ton downward. This is fastened to
the bridge by immense hinges which
allow it, when in operation, to swing

an elevation of $50 feet above the tide
level.
Should this motor prove rs success
full as the projectors seem confident 1T
will, several others will DO built in
the same ncighborhood aud an im-
| mcnsc reservoir built on the hill to
contain tho water.
This one motor, with its twelve
inch plungcr, is capable of raising
1000 cubic feet of water $50 feet
high in every twcnty-four hours. The
uses to which the water will be put
arc various. A thirty-siX inch pipo
will be conducted to the city and water
will be supplied to all branches of ike
dustry where machinery is used.
Bathing houses will also be supplied
with salt water and sewers flushed
where it is necessary.
The first work performed will DO
begun in about ten days, and an eight
inch pipe is now being laid for the
purpose.
Tho last mentioned rApe is for
Adolph Sutro and is to be utilized in
sluicing away a large amount of drift
ing sand from the heights just back
of the aquarium. This work is ren-
dcred necessary to prevent the sand
from washing back on the beach and
retarding the work there.
The immense fan of tho motor gem
crates II large amount of energy
which is not used in working tho
pump, and when everything is in
shape electric dynamos will be erected
to utilize this energy for heating pur-
poses and the like.
