The use Of electricity for Slaughter
ing hogs is proposed. tits claimed that
the current will not only kill the hogs,
but will kill trichine at the same
time.
Experiments with the $4,000 candle
power search lamps show that vosseis

and that. by throwing tho light on the
clouds, signaling is possible at distance
OF fifty miles
M. IIegfroky, who recently, before
tho Hungarian Academy, read a paper
involving tho results OF five years study
of thunder storms, stated that he accept
ed Sohncke's theory that the electricity
of thunder storms is due to the friction
of water drops on ice.
The perfected target for firing at
the small-arm ranges is worked by elec-
tricity. by means of contact and bat
terry, there is communication with tho
indicating apparatus at the firing end OF
the range, showing which section OF the
target has been struck.

NIhe latest wonderful discovery Is
reported from Syracuse, n. Y. A man
there has discovered a bed OF what ho
calls electric rock, which, according
to his reports, is endowed with wonder
ful properties. 1t Will generate unlim-
tied power, and give any amount OF In
candescent light equal, II not superior,
to that produced by manufactured elec-
tricity, In addition to which IL Is cheap
or than Kerosene. ono small charge OF
400 pounds oil rock Will produce Light
and power enough Tor whole year
before losing its force and 1t is perfect
ly harmless, making insulation entirely
unnecessary.
The idea that electricity flows
through n wire somewhat as water hows
through a pipe is likely TO pass away,
as reasons appear for believing that the
energy is not transmitted by the wire
at all, but by the surrounding ether In
some experiments by Prof. j. j. Thom-
son, the velocity OF electric disturbances
along wiro surrounded by air was
nearly double tho velocity along the
same wire surrounded by sulphur ana
