jestic is the most economical coal burner |
of any of the Atlantic ''high flyers"
She burns 220 tons of coal a day, |
shows 19,500 horse power, and makes |
an average of over 90 knots, or % miles |
per hour throughout the Atlantic pass
age.
"A railway is to be built across En-
gland that will enable passenger to
make direct trip from the Mersey to
the shores of the North Sea. 1t will be
about $50 miles in length, and the ex-
pense of purchase and construction will
be at the rate of 100000 per mile

in 1885 the mica product of the
United States amounted to lat, 41O
pounds, worth S36S, 525, while that OF
1889 was but 49, 500 pounds, worth only
$50, 900. Since there is no decrease in
demand for this article this decline in
the home production can be attributed
to no other cause than the large guam
titles imported from Canada and other
i foreign countries.
The vastness of Names timber
wealth, says the Southern Lumberman,
| is not generally appreciated. Every
| year now 500, 900, 900 feet of logs are cut
in the state, about one-third of this
amount floating down the Penobscot,
and the quantity of manufactured lum-
Der that has been shipped from the
state since the first sawmill was started
is enormous beyond description.
"A novel cure for nervous diseases is
being practiced in Worishofen, Bavaria.
The treatment is the outcome of the
study of an old priest, and consists
chiefly in spraying water over the body
in various places, dressing at once with
out drying, and brisk walking immedi-
ately afterward. The diet is carefully
attended to, and thousands have been
cured of nervous troubles which had
defed all previous physicians.
"A gigantic tunnel, which is est.
mated to cost $3.50, 900 and require ten
years to finish, is being constructed in
the Leadville mining district for the
purpose of draining the mines. 1t will
be at least five miles long and will,
when completed, leave to easy access
millions of tons of good ore that cannot
now be properly got at and probably
never can be handled without the use
of proper drainage.
The respiration of insects has been
the subject of study by Mr. Contejean,
who has found that contrary to what
takes place in vertebrates, the move
ment of inspiration is passive and thai
of expiration active. The air is driver
from the body by contractile effort
Hence, when the insect is wounded, the
flow of blood occurs at each expiration
The respiratory movement is not inter
ruptea by cutting off the head, nor b.
the absorption of the curare, which pro
duces an immediate cessation in man.

which necessitates the employment O
thirty-six furnaces, which, togethe
with the mines, furnish work for 93
hands. A flask of quicksilver is pre-
duced at cost of $50. 81. The world
Q production of this article during the pas
decade is 1,O93,611 TASKS, the Unite
d States producing more of this amoun
y than any other one country on tn
