The adulteration of tin with lead
by manufacturers at the present day
is becoming matter of serious i'm /.
portance, since such vast amour,
of that material is being used in
making cans in which to preserve
fruits, jellies. vegetables, etc. to be
eaten by the human family. Lead
Is a well known poison, end to take
it into the stomach, even in small
quantities, is exceedingly dangerous.
10 detect lead 10 tin, rub your hand
hard and briskly over it. If your
hand is backened, lead predominates.
Good tin will blacken the hand q
very little. Good tin also has a
bright appearance while the adul.
terated has dull blue look. Fruits
containing acids. put up in these
lead cans will corrode aud pertake
of the poison, and the person eating
such fruit will certainly do SO at the
hazard, at least of his health, if not
his lite. Manufacturers palm of
this bogus tin on the public because
lead is cheaper than tin and by it's
use their profits are greatly increas-
ed. Some legislation is certainly
necessary and should be instituted
at an early day to put a stop to this
wholesale poisoning.

consists of an electric apparatus
which is placed under the seat of
the driver. A conducting wire run
ming throgh the reins connect the
apparatus with the bit. Should the
animal become manageable or

By means of system of irrigation
it is ascertained that the Algerian
Sahara, heretofore and still barren
desert, is susceptible of being made
a most fertile region. The ground
thus prepared has been found to
produce wonderful results, and IN.
der its operation a soil has been con.
stituted in which the inter-tropical
plants grow with great vigor. So
enthusiastic are those'engaged in
experimenting that a writer asserts
that, "henceforth it will be safe to
say that the Transformation OF the
Sahara into fertile region is only
question OF time, labor, artesian
wells, means OF communication and
security"
