SCIENCE AND INDOSIHI.
In the State of Maine there are 84,-
600 pounds OF ground wood fiber and
1850 pounds of chemical wood fiber
made daily.gr 6'Nt -
"A nowgvegetable fiber, called ''ga-
lnootic," is imported from Cclibes into
Holland, and is made to- take the place
OF moss and hair in upholstery
The Manufacturer and Builder de-
clares that there are at present no less
than 10000 electric motors In use
throughout the United States. LIZ
'--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
paris, ,,of locomotives on many railroads.
1t Is only comparatively a few years
sincc 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, It's fiber
having proven valuable for variety
of textile fabrics. In Dresden thread
is produced from 1t so fine that length
of sixty miles weighs only two and one
half pounds. ft~
According to Prof. Sargeant, 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
phurous, have been found in snow
which has freshly fallen, the amount
increasing with great rapidity after it
has lain on the ground for a length OF
time. In recently fallen snow seven
millegrammes of the two acids were
found per kilogramme; the same snow,
after the lapse of two weeks, was found
to contain ninety-two millegrammes OF
the acids.
The Westinghouse Electric Com
pany has completed an incnndescent
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 expected to burn easily from
90 to 5000 hours without discolora-
on. Discoloration has been q stumb-
ing-plock in the way.of incandescent
lamps ever since theyswere invented. =

There are twenty blast furnaces in
and about Pittsburgh, thirty-tive 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 SIS, 900 tons, steel works, 750, 900
tons, plate-glass works 3 3.250, 900 square
feet. window-glass works 100000.
: There are a number of wooden mills
and knitting factories in operation in
Utah where hosiery, mittens, leggings,
iduleS hIlU SkifbS anu ul5NS RnlU un-
derweaS are turned out in large guam
titles. These goods are exported
throughout the entire mountain region.
In one of these mills the outpnt is ZOO
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 inlets 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 abusiness
that gaves employment to a few score
of hands. 1t now employs more than
1900 fishermen, nearly 1000 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 a boat, with 200
traps, at a cost OF about $500 for the
entire outfit.
