Photography has determined the
cause of the recent glacial avalanche in
the Alps. 1t was hydraulic pressure
beneath and behind the glacier, pro-
duced by masses of ice falling into con-
Meeting water above and at a consider

Indiana will make fine display at
the worlds fair of the results of manu-
featuring industries growing out of the
discovery of natural gas. Since Indiana
first began to use the gas in 1855. il is
claimed, the growth of manufactures
in the state has been greater than in
any other state in the Union.
The best lockwood comes from the
Caucasus hitherto Turkish territory,
but taken by Russia. Since 1872 some
OF the forests have been closed and
Others denuded of the tree. At that

Abasian lockwood, and as much as 5000
tons have, in some years been imported
from that country.
The only wild monkeys in Europe
are those which inhabit the Rock OF
Gihralter. They We're once numerous
and bold, but the constant persecution
of their human brethren has made them
quite shy and reduced their tribe to the
verge of extinction. The remaining rep
resentatives of the tribe-probably less
than score-are carefully preserved

Prehistoric human skeletons have
Been discovered in the excavation of a
cliff in Switzerland. These skeletons
are no nearer the ape than modern
ones. Nogt said recently that all the
races of men have been visited, and hui
man bones exhumed in all the coun-
tries, and yet not shadow of trace of
the missing link had been found.
Throughout all Japan there are
now open for traffic l,7l7 miles of rail-
way. The only section in the neigh
borhood of the capital which has been
opened during the past twelve months
is that stretching northward to Awo-
mou. This line, l2e miles in length.
was opened in the autumn of 1891, and
railway communication has thus been
completed to the most northerly coast
of the mainland of Japan toward liado-
date. The only other line in progress is
the filing up OF gap of five miles in
the line connecting Yokohama with the
northwest coast
Over 80, 900 pounds of beet sugar
have been produced at the Chino fac.
tory in San Bernardino, Cal, from this
years crop, showing an enormous
growth of this industry in the state
Four hundred thousand acres of beets
Were planted against 200 acres last
year. The growers have netted $3.50 a
ton. and one man, who bought twenty
acres of land and raised fifteen tons to
the acre, paid for this land with the
first beet crop. Since a bounty was
placed on beet sugar the farmers of
California have been quick to see the
profit in this industry.
The limit of size in object glasses
has not yet been reached. The maker
.or polisher) of the reflector for the
Lick observatory believes that he can
turn out perfect object glass five feet
IN diameter if some one gives him an
order for il. The chief difficulty in
constructing large refiectors is mechan-
zeal 1t is hard to cut glass disks of
great size perfectly free from defects.
Even if Instruments several times as
large as existing refiectors should be
made II is by no means certain that
their power of penetrating the mys-
terses of the heavens would be proper
