Prof. Boutan has succeeded In making
snapshot photographs OF fish in the sea
AZ g depth OF about nine feet His plan
is to let down into the water a white
sheet, and then attract the fish in front
OF 1t by q judicious distribution OF
toothsome bait. The object Of the pro-
ceeding Is to increase our knowledge OF
the movements of fish when aot con-
strained by artificial Surroundings or
confinement. 1t has been proposed to
lower cameras two or three miles In the
sea and make photographs there by
flash-light, but the enormous pressure
at such depths would, 1t is objected.
crush the apparatus.
1t has been averred that but for the
saltpeter furnished by the Mammoth
Cave Of Kentucky and by some smaller
limestone caverns the United States
would have been unable successfully TO
wage the war Of 1872. Even during the
Civil War these cave supplies Of salt
peter were largely utilized for making
gunpowder. Recently the question OF
the origin Of cave saltpeter has been
discussed anew In the Journal of Geol-
ogy, and w. II. Hess, dissenting from
the view that the saltpeter deposits are
due to the formation of guano by bats,
holds that they have originated from
the evaporation of water which, as II
percolated through the roof Of the cav
ern, absorbed nitrates from the soil.
Russia authorities are displaying re-
markable energy in connection with the
utilization Of Popoff's wireless tele-
graphic system. All the lighthouses in
the Black Sea are to be provided with
this apparatus, and several stations are
to be erected on the shore, so thai COM
munication may be maintained between
the shore. lighthouses and the war
ships within the radius Of the electric
waves. Two hundred complete installa-
tons of the apparatus were recently
dispatched to VladivOstok and Port
Arthur, and the work of fitting out the
Russian wa-ships in the Pacific is to
be carried on with all possible celerity
The two ports are also to be connected
by the establishment Of intermediate
stations along the Korean coast.
