Earth Dams.


is, and it may be or may not be
crudely constructed; but certainly no
type of structure that man builds 10
confne water can compare in perma-
hence with the earth embankment.
Wood decays and metal corrodes.
Stone, In a longer or shorter time,
crumbles under the action of the
weather, Earth, however, has al
ready experienced all the changes
that the gnawing tooth Of time can
bring. II cannot disintegrate, for 1t
is already disintegrated. Temper
ature stresses, which cause the en-
gineer so much anxiety in other struc-
lures, have no terrorB for the earth
embankment. The only dangers to
which it is subject are overlapping
by floods, saturation of the mass by
water until the whole yields like a
semi-liquid to the pressure behind it,
and erosion of the side slopes. How
shall the earth dam be made water
tight? All kinds of earth are more
or less permeable to water. Through
gravel water flows rapidly, through
sand steady flow also occurs at
rate depending on the degree of fine
ness ard the percentage of voids. 1t
is orly earths containing clay or
vegetable loan which have the prop
erty of checking the passage of water
so greatly that the flow through them
is practically nothing. To build an
earth dam, therefore, the engineer Sc
lects from the earths available near
the site those of the most clayey
character and places them in the
center of the bank to form the puddle

Artificial Marble.
Tho lack of marble in Denmark has
led to many attempts to produce
substitute which would equal in
decorative effects the natural product.
A Danish master builder is producing
a stone of such delicate transition of
tints and play of color that it is i'm
possible to distinguish 1t from the
natural product. while as to cost of
manufacture, IL can compete with all
other artificial marbles. The imi-
tation of the more expensive species
does not exceed In cost that of the
cheaper ones.
The process of manufacture is
simple and the cost of the output
does not exceed sl75. The article
can be produced in any form desired
columns. plain or fiuted, and cap
itals-as readily as fiat slabs. Ii is
claimed that even pictures may be
made of this material. IL seems to
have the durability of genuine marble,
but Its cost Is only about one-tenth as
much.
AeetyIene Gas.
A new acetylene generator is
described as being much simpler in
construction than any yet placed upon
the market In its operation the fall
ing of the carbide into the water Is
automatically regulated by hollow
rubber ball which. as soon as 1t is
filed with gas, closes the valve be-
tween the carbide and the water.
When the volume of gas decreases.
the rubber ball contracts and the feed
valve again permits the carbide to
drop, The gas is stored partly in the
rubber bail and partly in the space
between the funnelshaped carbide
magazine and the water. II more
than toe normal amount of gas is
generated, IL secures more room by
forcing the water through valves into
the water jacket in the sides of the
apparatus. A separate gas tank is
therefore not needed. Should too
much gas be produced, both the water
and the gas escape through safety
valve. Common carbide Is used no
cartridges.
Electric Shocks.
Electric shocks cause death by pro.
ducing, IL Is said, a spasm of the dia.

Little can be done to help anyone who
has received a heavy shock of cleo,
tricity. The best-known way Is To

make the blood gravitate toward the
