Among the insects while the perfect
state is generally limited to few
months, certain Of the bees live for a
few years. and the same Is probably
true Of the ants.
The SUMS heat raises from the earth
thirty seven million tons of water
minute. TO do the same work arti-
ficially. a cube Of coal two hundred
miles deep high and wide would have
to be burnt every second.
Consumption Of ice in Brazil is con
stantly increasing. This is due prin-
oipally to the demand for ice in restau-
rants, hotels and other public places.
Foreigners are most insstent in their
calls for Ice Our consul at Santos IS
Of the opinion that an Ice company
would prove profitable undertaking
in that place, the use of Ice being prac-
tically unknown In the fish, vegetable
and meat markets. lie also thinks the
American refrigerator would sell well
in Brazil.
The Metropolitan and District rail
ways Of London have suffered severely
owing to the competition Of the omni-
buses and the Central London railway.
They have been losing at the rate of
$1,000 a week for the last half year and
the District railway has decided to
adopt electric traction The change

in short time. The directors have
been given full power to raise addi-

Some two years ago a resident of
Boston, Mass, devised a new spinning
machine which he took with him to
Bradford, the center of the spinning
Industry of Great Britain. There.
aided by local engineers and experts,
he improved his appliance, which is
now in active operation. 1t is capable
of spinning a variety Of materials,
such as asbestos and peat moss, as
easily and as readily as wool, and
when completed 1t is difficult to deter
mine the original nature of the fabric.
An instance Of the transformation by
scientific means of deleterious into
a useful substance is furnished by a
process recently invented in Germany,
in connection with the manufacture of
superphosphate fertilizer where apa-
lite Is used. The large volumes of
hydrOhuorlc acid that are given off
seriously contamlnate the atmosphere,

recovered in the form of fiuosilicic
acid, which Is used in the manufac-
ture of artificial stone for hardening
soft limestone and sandstone, and for
other purposes.
Fishing is one of the leading indus
tries on the eastern coast Of Siberia,
and ON account of the rlgor of the eli
mate and the poverty of the soil in
some parts of the Amur country, 1t is
the only means of obtaining food. Many
of the Russian settlers moving into
that region are compelled to take up
fishing for a livelihood. Fortunately
in place where they are so sorely
needed, fish are extremely abundant
and the sea along the coast teens with
them. The gathering Of seaweed is an
other important industry OF eastern
Siberia, but It is carried ON almost ex-
clusively by the Chinese.

An English inventor, Cecil Varlcas
has constructed a submarine torpedo
which can be steered by means of ether
waves transmitted as in wireless tel
egraphy. The torpedo, in addition to
the usual explosive apparatus. carries
Il Marconi coherer, in circuit with h re-
lay and battery. SO arranged that it
governs the movements of the ruddor.
A fine wire, attached to metal float,
keeps the torpedo, when submerged,
In communication with the air and
consequently with the ether waves.
BY means OF a wireless telegraph
transmitter the apparatus in the tor
pedo is actuated from the shore, or
from a battleship, and the torpedo's
movements are thus controlled A
test Of this device was recently made
in the English Channel, and the tor
pedo was caused to describe a compli-
Gated path and return to the starting
point.
