iains that odors are due, not to the ema-
nations, as such, of so-called odoriferous

Resin should not be used as a rem led
fer slipping belts. If IL is, it will pro-
duce immediate adhesion of tho belt to
the pVlley, acd the resin will soon be
ground into the leather, siiffen the

belt worse than it's first.
Aluminium united with some metals
produces a very remark able alloy of the
color % amber, vsrginR On gold, with a
very fine grain, exceedingly tough and
malleable, and susceptible of fne polish
which it retains, not being affected by
sulphur. It's castings are very sharp, and
stronger and tougher than Bessemer
steel.
DR.. j. A. Linter, the well known en-
tomClogist, says there are in the world
320009 species of insects, 25,000 of these
belong to the United States, and about
$4,000 prey upon the productions of man;
1909 of s 600 of these could be considered
IS being fruit pests. On the apple alone
no species are kEown.
Science has claimed the sponge fishery
Of the Mediterranean. The native divers,
who could stay under water not more
than two minutes, are being driven out
by men in regular diving arm0r, who can
work by the hour. A German professor

When a small grain of potassium, the

The force of s.eRm boiler explosions
can be illustrated by getting tube made
