Jupiter was known to the Chaldeans as
planet as early as B. G. 5000.
1t is said to be a geological fact that
gold strata underlie Philadelphia.
The planet Neptune has the longest
year, consisting of more than 10000 of
our days.
More than one.half of the street rail-
way-mileage in Massachusetts, is now op-
Grated in whole or part by electricity.
The moon gives out heat enough to
affect the thermometer and makes "a diff
ference of two degrees or three degrees.
The average weight of the Chinese
brains is said to be heavier than the av-
erage weight of the brain in any other
race.
On the Royal Sovereign, the new Eng
lish battleship, there are 800 electric
lights, connected by thirty miles of
wire.
Inventors are now turning their atten-
ton to devices for the utilization of
electric heating, especially for domestic
purposes.
The largest pumping plant in the
United States was that placed in mine
at Iron Mountain, Mich. 1t pumps A.
600, 900 gallons in twenty.four hours.
Genuine volcano dust has been found

To make glue water proof, dissolve of

Seventy. five miles an hour is ITO feet
q second, and the energy of 400 tons or

strong gun.
In the manufactures of Great Britain
alone the power which steam exerts is

From a rift in a great rock at
Santa Cruz (Cal. water spouts to
height of sixty feet. The waves that beat
on the shore near by have worn tunnel

A fine specimen of the egg of Epyor-
mis-, the extinct giant bird of Madagas-
car, snd obtained from southern Mada-
gascar, was exhibited at a recent meet
ing of the Geological Society of Lon
don. 1t will be remembered that this
egg is about thirteen inches long and of
the capacity of $50 hens eggs.
The captains of ships which carry
bricks have to be very careful. An or
binary brick is capable of absorbing a
pint of water. So with cargo of brick
in the hold serious leakage may quite
well go on undetected, for the water
that enters is sucked up as fast as it gets
in. If this should be the case, the con.
sequences are bound to be most serious.
Exploration is improving the popular
knowledge of the Sahara. Instead of
being largely below the sea, the greater
part of it is from 5000 to 5000 feet
above the level; instead of being rainless,
showers make il bloom and cover it with
green grass for few weeks every year;
large flocks and herds are maintained
upon its borders; the oases are depres-
,ions where the water can be collected
and stored and are villainously unhealthy
in hot weather because of this stagnant
water and the habits of the inhabitants.
