"A frozen soap bubble broken ia
two and floating like an irridescent
transparent egg she'll on the surface OF
a vessel of liquid air was one of the
most marvellous sights shown by Prof.
Dewar recently in a lecture at the Royal
Institution, London, on the effects ot
intense cold.
OF total of 100000 acres in
South Carolina, 5000, 900 are improved,
while the remaining s,0OO,0OO are un-
improved. In Georgia out of $4,000, 900
acres, only 9,5O0,000 are improved.
Either of these states probably contains
a greater percentage of unimproved
land than any other in the Union.
The dragon fly. with 10000 lenses
In his eye, darts from angle to angle
with the rapidity of a flashing sword,
and as rapidly darts back, not turning
in the air, but with clash reversing
| the action of his four wings and instan-
taneously calculating the distance of
the objects, or he would dash himself
| to pieces But in what conformation
of the eye does this power consist? No
one can answer.

| seventy-three will not come to San
Francisco until the fall of 1894. The 9th
ers produced 1853, 900 pounds, and there
is on hand Al 900 pounds. Taking off the
amount sold the visible supply is reclS-
oned at 36i, 900 pounds, as against 402,-
| 800 pounds at the same time last year,
| at which date the bone was selling at
81 to So per pound.
Agricultural statisticians estimate
| that since 1910 the worlds production
of meat has increased 81 per cent,
while that of grain has increased 420
per cent. In 1855 the worlds total pro-
| duction of wheat was only 500, 100000
bushels, whereas now it is 100000, 900
bushels. Beerbohen, the noted English
authority on the grain trade and cereal
crops of the world, estimates the yield
OF wheat at about 104, 900, 900 less than
the crop harvested last year.
Advantage is taken of every ex-
pedient to utilize the heat of coal un-
der boilers The most important step
| in this line is to secure the ends of
angle iron bars to the interior of the
boilers heating surface and projecting
them through the water, and also pro-
| jecting similar bars through the fire
chamber. whereby the heat is taken up
by the bars and conveyed directly to
the water within. A test made on n
boiler thus constructed showed an
added efficiency of IS per cent. in the
heating capacity, which is certainly
remarkable advance.

grains, hops, yeast and water, the nor

all displaced. Glucose and glycerine
take the place of malt. For hops are
used beef oil, aloes, quassia, absinthe,
gentian, Cologne, salacine, island moss,
orange and lemon peel and various
other substances. Alum is used to clear
it. The color is improved by caramel,
chicory and various manufactured mix
lures.
Everybody knows that the earth
makes one complete revolution on its
axis once every twenty-four hours. But
few. however, have any idea of the
| nlgh rate OF Speeu necessary W accom-
plish that feat. The highest velocity
ever attained by a cannon ball has
been estimated at 1926 feet per second,
which is equal to a mile in SO seconds.
The earth, in making one revolution in
twenty-four hours, must turn with a
velocity nearly equal to that OF a can
non ball. In short, the rate of speed at
the equator has been estimated al
nearly 1,5OO feet per second, or a mile
every thirty-siX seconds, or seventeen
miles minutes.
