A new megaphone has been placed on

miles.
Two logs of curly poplar have been

Since certain sections of the tobacco
growing districts in the South have been
lighted by electricity, the ravages of the

AS ores can no longer be sent to the
United States, smelters will be built all
over Mexico. The gross bullion will
then be shipped for refining either in
England or Germany.
A new German water pipe is made of
glass covered with coating of aspsalt
and fine sand. The advantages claimed
are resistance to ground moisture and to
acids and alkalies, and impermeability
to gases.
The latest experiments made with car
rier pigeons in connection with various
European armies show that the normal
velocity of the carrier in calm weather
and for short distance is about 1910
yards minute.
The piece of crown glass, forty inches

NJ Jablockoff, of electric candle fame,
makes strong argument in favor of
going back to chemical reactions for the
production of electricity as motive
power. The dynamo machine does not
utilize more than ten per cent. of the
fuel, while more than ninety per cent. can
be obtained under favorable circum-
stances in electro chemical combinations.
This Hand Never Struck Me.
