SCIENCE AND INDUSTRY.

In the State OF Maine there are S4.-
900 pounds of ground wood fiber and
188, 200 pounds of chemical wood fiber
made daily.
The Mqaaufacturer and Builder de-
clares that there are at present no less
than 10000 electric motors in use
throughout the United States.
One of the most remarkable me-
chanical changes of the day is the set
ting aside OF steel and the readoption
of iron for some of the most important
parts of locomotives on many railroads.
1t is only comparatively a few years
since the change was made, on most
roads, from iron to steel.
The nettle is among the substances
which science has put to use during
the past few years. This weed is even
being cultivated in Germany, its fiber
having proven valuable for a variety
Of textile fabrics. In Dresden thread
is produced from it so fine that length
Of sixty miles weighs only two and one
half pounds.
According to Prof Sergeant, the
strongest wood in the United States is
that of the nutmeg hickory of the Ar
kansas region, and the weakest the
West Indian birch. The most elastic
Is the tamarack, the white or she'll
bark hickory standing far below it.
The least elastic, and lowest in specific
gravity, is the wood of the ficus aurea.
The highest specific gravity, upon
which in general depends value as fuel
Is attained by the bluewood of Texas.
The two acids, sulphuric and sui
ohurous, have been found in snow
which has freshly fallen, the amount
Increasing with great rapidity after it
mas lain on the ground for length OF
lime. In recently fallen snow seven
nillegrammes of the two acids were
found per kilogramme; the same snow,
after the lapse of two weeks, was found
20 contain ninety-two millegrammes OF
.he acids.
The Westinghouse Electric Com
pany has completed an incandescent
lamp which is expected to give better
results than any lamp now in use.
Formerly a lamp which burned 800
hours was considered good; but the
new one is sexpected to burn easily from
$500 to 5000 hours without discolora-
ton. Discoloration has been stumb-
ling-block in the way of incandescent
lamps ever since they were invented
Electrical ReUiew.
There are twenty blast furnaces in
and about Pittsburgh, thirty-hve roll
ing mills, thirty-nine steel works, fifteen
window-glass works, thirty-seven flint
glass works, and eleven green-glass
works. The blast furnace makes 900,-
900 tons of iron per year, the rolling
mills 575, 900 tons, steel works 1900
tons, plate-glass works $3.50, 900 square
teet, window-glass works 100000.
There are number of wooden mills
and knitting factories in operation in
Utah where hosiery, mittens, leggings,
ladies' knit skirts and mems knit un-
ierwear are turned out in large guam
| titles. These goods are exported
| throughout the entire mountain region.
In one of these mills the output is 1000
yards of material per day. Thousands
Of dozens of handmade scarlet and
mems gray hose are sent into Colorado
and Montana. Their carriage robes
and blankets find a ready market in
Chicago, and the orders for these goods
are often fully up to the capacity.
The coast of Maine is SO indented
| by bays and in1ets that the actual shore
line is fully 2,400 miles in extent.
Along this shore are many of the chief
cities, towns and important industries
Of Maine. One of the most important
Of these Industries is the catching,
transportation, canning and sale OF lob
sters This is an industry that has
grown in thirty years from business
that gave employment to few score
of hands. 1t now employs more than
1000 fishermen, nearly 1900 boats and
/ forty vessels, and distributes in various
ways more than 5000, 900 annually. The
business of lobster catching in general
requires two men to q boat. with 200
traps, at cost of about $500 for the
entire outfit.
