under water, the tube serving as a
practically stationary pston.rod, and
the pump cylinder has a maXimum
stroke equivalent to ten feet. This
apparatus delivers water-for driving
turbines or other purposes with Il
pressure equivalent to that of a fall of
fully 800 feet. Among the many uses
for which it is believed this motor will
prove valuable is that of automatic fog
horns, kept in constant action by air
compressed by the pumps, and that of
light buoys, or beacons, lighted cleo
trlcally from n small power stationed
on the buoy itself. II is estimated that,
with wave oscillation OF only one
foot thirty times minute, each of the
eight-ton buoys so numerous on Brit
ish coasts should yield 80 horse power
for driving machinery.

the mortar. Herr Gunther. however,
finds that the disColoration is most
liable to result from pyrites in the
clay or chemical interaction between
bricks and mortar. Most clays con-
tain pyrites, which give rise to imme-

Sulphates-and not nitrates, as has
been suggested-are usually the dis

would bind the sulphuric acid, forming
