solving the problem seems to be ny APP

may be brought about by inclining the

The new gold-from- sea water scheme
OF a British inventor consists In the
construction Of shallow reservoir on
a chalky coast A ball-yalve would
open at high tide allowing the water to
enter with such force as to secure the
bottom Of the reservoir and stir no the
sludge, and the discharge would be
gradual through an outlet just above
low-water mark. II IL claimed that the
gold would adhere to the sludge, set
Ting with 1t In the reservoir. AS eacn

from two 10 fye grains Of gold, II n

by fusion or dsselving the chalk In

Bricks of uuartziferous sand mixed
with a small proportion OF lime can be
made in many PLACES whore clay rs not
available, and they have the advantages
of being proof against water frost W
acids. a serious difficulty In their
manufacture has been the extreamely
variable quality caused by changes Of
the weather. BY mixing the sand and
lime In a vacuum With steam heat, and
admitting steam 10 supply the exact
amount Of moisture. necessary, Wilhelm
Schwar Of Zurich has overcome TINS
difficulty, thus perfecting an industry
that consul r. II. Warner, Jr. predicts
will prove OF great importance In all
countries. The process lnsures be-
ginning Of the combination OF SILICA
acid and lime before the moisture Is
pressed into molds and prevents all

atmosphere. The apparatus consists OF
a steam-tight mixing machine provided

attached to exhaust the air and draw
out excessive moisture and a tube inside
for admitting the exact amount OF
steam required Proper management OF
three valves ensures uniform product.
