The English school at.Athens has

Gortys, in the Peloponnesus, and the
ancient theater of Eretria, in Eubea-
highlands boast that the south
African gold mines would out-produce
all the gold mines of the United States
has not been verified. The yield for
1890 was ss,655, 900, less by over a mil
lion than California's product for that
year-N. Y. Saturday Globe.
The greatest railway mileage in
any state of the Union will be found in
Illinois, namely, 10, 1877 miles. The in
debtedness against this mileage is 81, $685.

There are now under vine culture
in America 100000 acres, of which
about 3OO,0 acres are bearing. The
estimated value of the vineyards and
wine cellars is Sl55, 900, 900. In Califor-
MIA there are $50, 900 acres under vine
culture, and large proportion OF the
grapes produced are made into wine.
Most of the grapes grown in New York
state are sold for food. The total pro-
auctions of wine in the United States
during the past year is about 10000, 600
gallons.

porary, civilian Isaac, of Scitoria nn-
earthed portion of skeleton which
is reminder of the wondrous forms OF
animal life represented in ancient
times. The bones and teeth were found
imbedded in solid clay at distance OF
Atty feet from the top of the bluff. The
teeth measure across the end fifteen
inches, and weigh twenty-five pounds
apiece. The bones found are proper

The silver imported in Mexican lead
ores in 1890 is given by the director OF
the mint as 1889, 442 ounces, or about
252. 900 ounces more than in 1889. The
smelters and refiners' returns of produc-
ton of silver exceed those made by
them for 1889 by 7,s4l,526 ounces. 1t
would appear from the mint reports
that the production of gold is nearly
stationary, while our silver output is
increasing rapidly, 4, 500, 900 ounces from
our domestic ores as by the mint figures,
and a total of about 7,S41, 900 ounces, in
GLIDING all sources, as returned by the
smelters and misunderstanding and

The first sign of the Matching of a
snake, according to DR.. Walter Sibley. is
the appearance of a slit at a part of the
eggshell which happens to be uppermost.
The young reptiles snout appears at
the crack, and after a time the head
protrudes, and may remain thus several
hours before the body and tail are
Matched. If disturbed, the head is with
dawn into the shell, while fully
hStched snakes often seek their shells
al safe retreat. These infants are
sIlooth and velvety to the touch, with
eyes open from the first, and begin to
hiss at the age of few days.
| Yin Switzerland Sunday law has

haze fifty-two days off yearly, and
sefenteen of these must be Sundays
| M reduction in wages is to be made fol

The curious experiment of making
lens of ice to light pipes and cigars
has been tried with success by skaters
in London. The experiment was first
brought to notice by Dr. Scaresby, when
in the polar regions, to the great aston
ishment of his companions. who did moi
understand why the ice did not freeze
the solar rays. Prof. Tyndall, when 9
tutor in the Royal Institution. on sew
eral occasions set fire to little heaps OF
gunpowder with the rays from an cleo
trio arc concentrated upon the powder
by lens of ice. His explanation was
that, although ice absorbs rays of Ger
tain waves of light, and is gradually
melted thereby, other waves are not
absorbed, and these latter produce the
heating effect at the focus of the lens
1t is wholly question of the relativ'
motions of the molecules of frozer
water and the motions of the waves O.
