Within few years past over 100,-
OO0, 900 of those little wire cork screws,
used in ink and medicine bottles, have
been sold. Machines turn them out at
the rate of sc, 900 per day.-Pharm. Era.
Exports of breadstuffs continue
enormous and show wonderful increase
in value. One State street circular
points out that for the eight months,
July, 1891 to March /, 1892, their value
was $4,000, 900, against $4,000, 900 for
the same period in 1S9O-91.-Boston Ad.

-Earwigs differ from all other insects
in both their origin and structure; they
are Matched from eggs, like chickens.
Naturalists often report seeing the ma
ternal earwig with her newly Matched
brood crowded under her like chickens
under hen.
The perpendicularity of monu-
ment is, although few may be aware of
it, visibly affected by the rays of the
sun. On every sunny day tall monu-
ment has regular swing leaning away
from the sun. This phenomenon is due
to the greater expansion of the side on
which the rays of the sun fall.
1t is said that engravers in Germany
harden their tools in sealing wax. The
tool is heated to whiteness and plunged
| into the wax, withdrawn after an in
slant and plunged in again, the process
| being repeated until the steel is too
cold to enter the wax. The steel is
said to become after this process almost
as hard as the diamond.
| The prospects of the Chinese tea
trade continue to grow more gloomy,

meeting of teamen recently held in one
of the Foochow districts it was stated
that during the last five years, the hun

According to Prof. Mer, in Complies
Rendus, starch is very abundant
through the bark and woody structure
of trees about the fall of the leaf. 1t is
gradually reduced in quantity till the
buds begin to swell in spring, when it
is rapidly formed again. BY the end of
April in France there was as much as in
the previous September. These results,
from apparently very carefully con-
dueted experiments, completely reverse
what has hithertoo been regarded as
the "solid truths of science"
