SCIENCE AND INDUSTRY.

The people of Kansas, under the
forestry laws of that State, have planted
%, 500 acres in trees. The cotton wood
Is the most abundant, as it grows the
most rapidly. About 5000 have been
planted in black walnut, and will make a
handsome return in eight or nine years.
The Scientific american pictures and
describes an instrument called the gas
troscope, by which it Is possible to IL
Illuminate the interior of the stomach,
aud see the condition Of its lining men,
brane. 1t is an ingenious, delicatN and
probably very costly instrument, and is
more interesting as showing what can
be done than what is likely. to be done
frequently.
by means of series of very inter-
esting experiments regarding the mus
cular power of insects, NJ. F. Platesu
has discovered that while horse can
not exert a stress beyond the sixty-sev-
enth of its weight, cockchafer can
times its weight, and bee can draw q
little wagon twenty times heavier than
itself.
Silk Culture Association in Philadelphia,
prize of $500 for the best cocoons, which
counted 157 to the quarter-pound and
yielded 1-S ounces of silk and 27-S
ounces of waste. Mrs. Taylor lives at
Kennett Square, Delaware County, Pa.
and Is the mother of the late Bayard
Taylor. She is eighty-two yesrs of age.
Sixteen American inventions Of
worldwide adoption-are the cotton gin,
the planting machine, the telegraph, the
mower and reaper, the rotary printing
press, steam navigation, the hot air en-
gine, the sewing machine, the India
rubber industry, the machine manufac-
tire of horse-shoes, the sand blast for
carving, the gauge lathe, the grain ele-
vator, artificial ice making on large
scale, the electric magnet, and the tele-
phone.
Another car-brake has been invent
ed, designed for braking all the cars of
train at the same time by o single op-
Grafton, this object being accomplished
by the application of the device to q
common form of brake at present in use,
which brakes cars independently of the
other. The mechanisms consists in q
number of extensible connecting rods
attached to each car, which themselves
actuate pulleys upon each car and wind
up chains which govern the brakes. BY
this form of construction, the ordinary
form of brake attachment is not inter-
fered with, so that either can be applied
at will. The arrangement is such that
it can be operated by the engineer or q
man in the rear car, and, by drawing
upon the rods on different sides, both
can operate it at once.
The impression that the Northeast
ern coast of the American continent is
slowly rising-the estimate of the rate
Of emergence in progress being over q
foot, and perhaps as much as three feet
IN century-has recently been contro-
verted by eminent scientific authorities,
among these being DIR. Mitchell of the
Coast Survey, who states that the salt
marshes are still, as they were in the
time Of the early explorers, at ordinary
high water level, and that the rocks on
our coast, long notorious as dangerous
to navigation, have not risen since they
were discovered. Ancient maps and
documents are cited, and the conditions
Of the various rocks are considered in
detail, with the result just named. But
eastward of longitude 64 deg. IS min,
and especially in Newfoundland, great
changes present themselves in the COM
parison of charts, the depth appearing
to be at some points less and at other
points greater now than formerly.
