loaned to The Commoner by that pa
por. It says:
Tho editor of the Imperial Farmer

of a generation. He has seen River

and hopeless of deserts into one of tho

tops of tho mountains ho has seen

gated area of Southern California had
practically been doubled by water de
velopment as tho result of the drouth.
Ho was not surprised when it was sug
gested that tho great Colorado desert
bo moistened by the river of tho samo
name and that a district of something
like a million acres was to be wrested
from the hand of aridity. Nor was lie
surprised when an old friend recently
invited him to visit the Ostrich Farm
.at South Pasadena and behold how in
ventive genius had succeeded at last
in hitching an engine to the sun.
The Solar Motor is a success. It op
erates a compound engine and centri
fugal pump by means of steam, and
that steam is created with no other
fuel than the heat of the sun concen
trated upon a boiler, which is the focal
point in the center of a large reflector
lined with many small mirrors. We
have no idea that this device, which
thus eliminates all cost of fuel at a
single stroke, has reached the limit of
its possibilities. But already it has
recorded the following performance:
developed a steam pressure of 210
pounds; evaporated 192 pounds of wa
ter per hour under 150 pounds of steam
pressure; driven a ten-horse power en
gine and centrifugal pump; elevated
1,400 gallons of water per minute
(equal to a flow of 155 miners' inches)
twelve feet from an underground tank.
Wo do. not know why, if this can be
done with a single refle r, ten times
as much cannot be done when several
reflectors are grouped aboutr a central
eugine, since it is patent that the ef
ficiency of steam increases with the
size of the engine. Nor do we see any
reason why steam power generated by
solar heat will not serve all other in
dustrial uses as readily as it will pump
water. Apparently there are no in
superable obstacles to the storage of
this power so that it can be used
nights and cloudy days, though this
would necessitate tho generation of
electricity and use of storage batteries'
until other and cheaper methods shall
have been devised. It is easy to spin a
web of possibilities to come fronrthis
new invention, and if there are doubt
ers they need only be reminded of the
fate of all the other pessimists who
have been run over by he swift wheels
of events, in the west.
Tho prohibitive cost of . fuel . has
greatly retarded the growth of mining
districts in many places, compelled
communities of considerable size to do
without ice-plants, and deprived small
towns of domestic water and of electric
lighting systems. But most impor
tant of all, the cost of pumping has
kept millions of acres barren which
could not well be irrigated from reser
voirs or streams. If the Solar Motor
can be constructed cheaply enough to
meet these conditions there is certain
ly a wide field for it, and it may be
ono of the most potent influences in
the development of the west during
tho new century.
Tho accompanying illustrations will
give the reader a very fair idea of the
appearance and construction of this
device. But the pictures should be sup
plemented by a few facts touching di
mensions and materials.
Tho reflector measures 33 feet, 6
inches across tho top, and 15 feet
across tho bottom. It is lined with 1,
788 mirrors, each measuring 14x3

glass. The familiar principle of the
