1t appears, from an article in a
French scientific Journal. that analyses
have been made of articles found in
Egypt which show that bronze was in
use in that country more than two
thousand years before the Christian era.
What is expected to be the second
largest bagging and cordage factory in
the United States is soon to be located
in Galveston, Tex. 1t will contain fifty
looms, and most of the machinery will
be obtained from this country, although
the spinning and carding machines will
come from England.
1t is believed by writer for the

indicate that the sanitary condition of
locality depends on its volume of
ground water; that is, on the amount
of water contained in the ground. 1t
is stated that 1.-THE years in which there
has been large quantity of ground
water present have invariably been the
healthiest years, while those IN which
there has been small quantity have
invariably been the most unhealthy
periods. IN 7. Ledger.
According to Professor S. P. Lang
ley. the well-known American astron-
omer, the temperature of the sunlit
surface of the moon has been commonly
over-estimated and probably does not
exceed fifty degrees centigrade. Mr..
Richard A. Proctor, in his elaborate
work on the moon, says that during
| the lunar day, the surface of the moon
burns, one may almost declare. with a
heat of some five hundred degrees
Fahrenheit. if the differences of our
most skillful physicists and the evidence
obtained from our most powerful means
of experiments can be trusted.
Chemically considered, man is COM
posed of thirteen elements-tive being
gases and eight solids. In man
weighing 154 pounds tho oxygen, &C
cording to French authority, weighs 81
pounds, chlorine about &c ounces, and
fuorine 81 ounces. He is therefore
made up chiefly of gases, which in
free state would occupy about 1000
cubic feet of space. Carbon and calci-
UNI represent the bulk of the solids; the
phosphorus, sulphur, potassium, sod-
UNI, and iron weighing only from II to
&c ounces each. -ArkansaW Traveller.
The shipments of iron ore from the
Lake Superior ports during the season
just closed aggregate 4,372, 1877 tons, as
compared with 3,443,6 72 tons in 1886
By ranges the shipments have been as
follows: Marquette range, 1855, 754
tons; Menominee range. 1882, Gil tons;
Gogebic range, 1.091, 335 tons: Vermil-
ion range, 800, ACT tons. The Marquette
Mining Journal presents statement of
the shipments by lake from twelve of
the larger producers among the mines
of the Marquette, Menominee and
Gogebic ranges, total being 2,377, 166
gross tons.
German scientists are studying the
boomerang with view of discovering
the secret of its curious course of flight.
AT an exhibition of boomerang throw
ing at Munster, by party Of native
Australians, some extraordinary facts
were developed. The boomerang was
jerked up into the air. and when it had
assembled about a hundred yards it flew
away in a straight line, then turned to
the left and returned in q curved line
back to the thrower, whirling around
constantly and whizzing unpleasantly.
One boomerang, owing to some fault in
the thrower, went astray, and coming
in contact with a spectators hat. cut it
in two as cleanly as q razor could have
done" This alarmed the scientists, as
it was seen that any one of them might
possibly have his head taken off by a
misdirected boomerang. y Ledger.
