There is a place in San Francisco
where the skins of dogs are made into
gloves, their hair is used in plaster, their
bones are ground for clarifying sugar
and their fat is manufactured into oil.
Jupiter is larger than all the other
planets and satellites of the solar sys-
tenn. The sun is little more than 1000
times larger than Jupiter But Arcturus
is $50, 900 times larger than the sun.
The apparent fattening of the vault
of the heavens has been found to have
an annual period, and to depend on
clouds. 1t seems least fiat with a misty
horizon, and less by night than by day.
The erosion of big guns is thought
to be largely due to igniting slow-burn-
ing powder at the base of the charge,
whereby the bore receives attrition
from the hard, unburnt portions of the
powder
"A recent order from an Australian
firm for twenty million feet of lumber
will require twenty-five large vessels to
carry it. Recent extensive develop
ments in mining interests in Central
and South America have led to large
| shipments of timber from this country.

The American red plum (prunas
Americana), instead of fruit, often bears
nothing but crop of bladders. This is
owing to the attack, in the earlier stage,
of a small fungus which is allied to the
fungus which causes the curl in the
peach leaf. The latter is called EX.
oascus defor mans: the plum bladder
fungus is Exoascus pruni.
Acting (British) Consul HoNie, at
Wenchow remarks in recent report
that it is not generally known that the
fruit of the Chinese tallow tree pro-
duces oil as well as tallow. Chinese
tallow is Il white, hard fat, formed on
the surface of the seeds. 1t is separ-
ated by process of steaming and press
ing through sieves 1t is from the hard
black kernels left behind that the
Chinese obtain what Mr.. Hosier de-
scribes as good lighting OIL of a
brownish-yellow color.
1t is well known that carbon exists
in three different forms-charcoal,
graphite and diamond-and that hither-
to every effort to transform the one
into the other has been in vain. 1t is
said, however, that charcoal has recent
ly been transformed in graphite by
passing cyanogen through a red hot
porcelain tube containing charcoal or
coke, sprinkled with powdered cryolite.
The carbon separates into bulky mass
of very slender filaments, which, after
being subjected to pressure, can not be
distinguished from graphite. Perhaps
some further experiments in the same
line may give the crystalline carbon or
diamond. New Orleans Picayune.
The village of Ludlowville, in
Tompl1ins county, n. V, has taken an
unexpected boom. Three years ago the
citizens of Ithaca contributed several
, thousand dollars to find out just what
was below the surface of Ithaca soil.
They hoped to find gas, but did not
strike itin paying quantity, but they did
find that Ithaca was over great salt
bed. short time ago some capitalists
began work there. At the depth OF
1,45O feet they struck salt, and after
drilling in solid salt seventy-fve feet
! they stopped work.
According to a recent estimate
S four-ffths of the engines now working
in the world have been constructed
e during the last twenty-five years. The
n steam engines of the world represent

e 1000, 900, 900 men, or more than double
: the working population of the worlc
: the total population of which is usually
estimated at 1,455, 923, 900 inhabitants
