"A South Carolina inventor will ex-
hibit q cotton-pickIng machine at the
Atlanta Exposition.
The recent discovery that cotton
seed oil Is q perfect and satisfactory sub
stitute for lard bids fair to create quite
. revolution in Southern household
economy.
Eastern tanners sometimes use the
fruit of the cypress tree in their tanning
operations, and 1t Is maintained that the
fruit and even the wood of this tree
makes very good tanning material.
Paper betting is used with success
in the machinery hall of an exhibition
now held in Japan. 1t is stated that the
betting made of paper has been tested
and found to be much stronger than that
made of ordinary leather. lra
AR. H. Chittenden is inclined to the
belief that In the stomach there are two
stages of digestion, separate one from
the Others first, in which the action of
the saliva can go on without hindrance,
and a second, in which pepsin alone is
active.
The canal across the Isthmus of
Corinth, begun by the Romans under
the Emperor Nero, but never finished
is likely TO be cut by the French, Gen.

AN inventor in Hartford, Conn.,,
has patented a belt which is made OF
iron wire, the selvages being brass and
copper. The weff is of cotton, several
threads being woven in without being
twisted together. A double fabric Is
made, between which, or inside of
which, q number of single heavy wires
are inelosed to taka tho tensile strain OF
the belt.
"A compound is described for the
preparation of what are termed safety
envelopes. That part of the envelope
covered by the flap is treated with a So
luton of chronic acid, ammonia, sui
phuric acid, sulphate of copper, and fine
white paper. The flap itself is coated
with solution of isinglass in acetic
acid, and when this is moistened and
pressed down on the under part of
the envelope q solid cement Is formed,
entirely insoluble in acids, alkalies, hot
or cold water, steam, etc.
"A new celluloid is said to be obtain
ed from well-peeled potatoes, which are
treated for thirty-six hours with solu-
ton OF eight parts OF sulphuric acid IN
100 parts of water. The mass is dried
between blotting-paper, and then press
ed. 1t is further stated that in France
smoking-p are manufactured out of
this new material which are quite equal
in appearance to the meerschaum. By
heavy pressure the material acquires
such q hardness that billiard-balls can
be manufactured from it.
2 Investigations into the cause of dis
ease in plants have been made on pear
and apple trees by Prof. 7. j. Burrill.
His paper in the July american Nata-
r,dlist opens up prospect that blight in
fruit trees can be combated successfully
by careful tests of the diseased parts and
the use of knife. He found the starchy
particles in the bark of diseased pear
trees full of bacteria, and succeeded in
inoculating healthy from diseased trees.
While cutting away infected parts the
greatest care has to be taken lest healthy
tissue become inoculated by the knife.
The yellows of the peach tree are of the
same nature, and the Lombardy poplar
and aspen suffer from q similar disease.
