SCIENCE AND INDUSTRY.
The British war ONCE has devised
. new -se for bullets expended upon
target practice at rife ranges The
present market price for spent cupro
nickel bullets II about $50 per ton.
and contracts have been made for the
recovery and removal Of these used
bullets from the various ranges
According to English correspond
ence. an automobile battery has been
evolved abroad which threatens Q rev.
olution In horseless travel In going
down hill the motor is reversed and
the battery recharges itself. so that
II is much stronger at the bottom
than at the top. A trip of over "a
miles was made on an American
built wagon equipped with this motor
and battery. with no stop for recharg-
ing.
As a consequence of the increasing
demand for superior grades Of sugar
In Japan, attention Is being turned
toward improving the very primitive
methods of crushing now employed
at Tainan. and turning out q cleaner
and higher grade sugar. says The
Engineer. As . first step in this d.
rection four iron mills-crnshers-
we're introduced during the year to
replace old stone crushers. but as the
same motive power-bullocks-is
used as before. this improvement is
limited only to the extraction of .
larger percentage Of Juice. and the
quality of the sugar produced re-
mains much the same.
Commercial agent Johnson. of STAN
bridge. Quebec. has sent to the state
department q report on the discovery
of q new wood preservative. He
says: The sap is removed from tim
Der and at the same time it Is impreg-
mated with chemicals to render the
wood either nreproof or impervious
to attacks of insects or to decay in
salt or other waters. Beechwood can
be made suitable for railway sleepers
or for boot and shoe lasts. n neces-
sary the impregnating plant can be
used at the telling ground. The cost
Of impregnating IL about two cents
per cubic foot. The cost Of the
plant Is about $1,000"

for finer kinds of glass the compart-
