From experiments made in Richmond,
VA, with electric heaters. it seems prob
able that passenger coach can be kept
warm at an expense of two cents an
hour, the current being supplied by
dynamo on the locomotive or tender.
a French storc-inason has discovered
cement which he claims to be stronger.
cheaper, and less liable to damage from
the action oil the weather than any pre-
paration now i'll use. 1t is not plaster,
but II heavy, viscous fluid, and is applied
with brush. It's composition is kept
secret.
Some experiments lately made ut the
Royal Polytechnic School ut Munich show
that the strength of camel's-hair beltin.
reaches 63l5 pounds per square inch,
while that of ordinary betting ranges
between 2230 and $3.50 pounds per square
inch. The camcl's-hair belt is unaffected
by acids.
sponge is point of coral rock by
the discharge of the carth's electric cur

a new shaping tool has been invented
"a machine in which two flat surfaces.

mechanical forms.
Among the latest American patents j.
one for process of obtaining dry feed
for animals from the refuse of starch and
glucose. The coarse refuse is first SUBJ
Jcctcd to pressure TO free ii from water,
and to it is added the tinc refuse, con.
tanning the glutinous heterogeneous parts
oil the grain. This combination is sub
iected TO pressure to express the greater
part OF the moisture, and finally placed
under the influence of heat, for the pur-
pose of evaporating the remaining moist
urc.
wonderful invention for rapid transit
Is attracting attention in New York.
The invention consists of an elevated
railway track of new design for a car
made OF demagnctizcd steel and running
upon single rail. The car will 60 a
distance OF 230 miles in M hour. The
invention will first be used for transport
ing small packages and mail matter, but
eventually will be adapted for the trans
portation of passengers. The cost is
trivial when compared to that of the
regular railroads.
Experts in house building have sug.
Scstcd that CRATES in second stories are
usually less safe than those below, as the
narrower joists give little room for the
boxing OF the hearth. 1t is also urged
that CRATES be examined carefully, to de-
terminc whether the back of Slc nuc is
simply of fouNinch wall, which is always
dangerous mt the back OF CRATE in
frame house. This can be determined
by measuring the distance the breast ex-
tends out from the wall, and, rs some
times the breast runs through flush with
the face of the wall in the next room,
the calculation is to be made accordingly.
