THERE are two locomotives on the
Pennsylvania Road, in daily service,
that, according to Pittsburgh papers,
have been run over one hundred and
ninety-nine thousand miles without re-
pairs of any description.
IT is an interesting sight to see the
great logs of poplar wood go through
the powerful machine at the Connecti-
cut River pulp mill at Holyokc Mass.
The wood, as it is brought to the mill,
is about the size of cordwood used for
fuel, and in this shape the machine
takes it and gnaws it up very fine. So
rapidly does this process go on that the
machine eats about seven and a half
cords of wood day, and this makes
between three and four tons of pulp,
After coming from the machine the
pulp is put into watts and reduced by the
action of chemicals. 1t is used for
the manufacture of news and book
paper.
HIDES have "riz," and leather has
"riz," and the tanning business gcner-
ally is in a very flourishing condition.
The market is firm and active. Since
spring hides have advanced about twen-
ty-five per cent, and leather of all
grades on an average about fifteen per
cent. For some years back stocks were
very heavy while the demand was light.
Now the stocks are very much dimin-
ished, owing to the scarcity Of hides in
great part, while the demand is much
improved. Hence, the tendency of
prices is upward. What Western man.
ufacturers have had to contend against
heretofore has been the excessive sur
plus at the East, which would make its
appearance hereabout whenever there
was the least opportunity for getting
rid of any portion of it.-Chicago Times.
The process of manufacturing gun
barrels has undergone wide change
during comparatively few years.
Formerly, an iron ''scalp," eighteen
inches long, six inches wide, half an
inch thick, and weighing ten pounds,
was thrown into furnace, heated and
curved in a rolling machine; it received
only two welding heats, but was
changed many times from the furnace
to the rolling machine, OF until it was
rolled to the proper size and extended
to the length of the barrel; in the roll
ing process, a cavity was preserved
with different sized steel rods, and,
while hot, the barrel was passed on a
rod into a Strengthening machine, then
annealed, cone-seated, bored, turned,
ground, milled, rifled and polished.
Now, however, the workmen start with
a steel bar eight or ten feet long and
about one inch in thickness; this they
cut into pieces six or eight inches long,
bore each piece, pass them into fur
mace on rod, then into the rolling ma
chine, and proceed as in the old process.

1T was long time, indeed, before
any one supposed that lump of soft
coal, dug from its mine or bed in the
earth, possessed any other value than
for fuel. 1t was next found that it
would afford a gas which was combus-
tible. Chemical analysis proved it to
be made of hydrogen. In process of
time, mechanical and chemical ingenu-
ity devised a method of manufacturing
this gas, and applying it to the light
ing of buildings and cities on large
scale. In doing this, other products Of
distillation were developed, until, step
by step, the following ingredients are
extracted from it: An excellent oil to
supply lighthouses, equal to the best
sperm oil, at lower cost; benzole, a
light sort of ethereal fluid, which evap-
crates easily, and, combined with vapor
or moist air, is used for the purpose of
portable gas lamps, so called; naphtha,
heavy fluid, useful in dissolving gutta
percha, India rubber, ETC.; an excellent
oil for lubricating purposes; asphalt
tum, q black, solid substance, used in
making varnishes, covering roofs, etc.;
paraffine, a white crystalline substance,
resembling white wax, and which is
made into beautiful candles.-M. y
