Crushed steel--made BY crushing in a
stamp-mill high carbon steel auenched
in cold water from an excessively high
temperature--is being used for cutting
stone. 1t is very hard, and cheaper and
more effective than emery.
lncandescent lamps placed near tho

An important innovation has been in.
PRODUCED in the shape of machine for
preparing molds for casting. The ma.
chine is designed to produce complete
mold at one operation, and thus to re-
place skilled hand labor in making molds
from pattern plates. tits claimed that
lad can operate the machine with the as
sistance of laborer, and is able to ram
and mold as many as 1000 boxes per

By means of an electric wire OF Do
meme, France, the power of waterfall
is transmitted three and quarter miles
from Its source, to paper mill, and
there utilized to the extent of two hun
ared horsepower. In the winter, when
the deep snow for about two months
prevents any but electric communication
between the generating works and the
mill, the power is sent as usual, and the
machinery of the paper mill is kept in
motion.
