England imports annually about

sidered that this is a very small amount
compared with what might be the case
were tho enormous supplies fully or
even moderately realized. F e.s
Recent investigation has shown

amounted to 465, 1877, 1872 pounds, an in

Der of double stars known and recorded
by astronomers is something over TO-
600, far exceeding the total number of
stars visible to the naked eye in the

others are being frequently discovered
by the great telescopes now in existence.
DIR. PIE Smith says of the gout,
that not all drinks will produce it, for
1t Is rare Id Scotland. Not all wines
will produce 1t, for it is rare in Spain
and Italy. Not all malt liquors will
produce it, for it is rare in Vienna and
Munich. But it belongs to the most
civilized times and nations, to the
stronger sex, to the most vigorous
period of life, to the higher classes Of
society, and to the most able. ~.
Near Baku, the center of Russian
petroleum industry, is witnessed the
anomaly of water used for steam pur-
poses costing more than fuel. The
water is bad and dear, selling for about
fifty cents ton, while ton of astatki,
which Is the residuum of the distifia-
ton of naptha, and is the combustible
naturally utilized, is sold at price
equivalent to thirty-six cents per ton OF
coal.
Long distance photography is rem.
dered quite successful by new camera
with telescope objective, which con-
sists of a concave lens of short focus
and a convex lens of considerable length
of focus. These are put at q certain dis
tance apart, depending on the differ
ence of the two foci. By the laws OF
optics this arrangement projects an In
verted image of an object at long dis
tance from the lenses. s.IaA .s.
Brazil with $4,000 square miles
and 14,ooo,ooo people is the United
| States Of South America. Her foreign

divided between exports and imports.
England sells Brazil s47, 900, 600 worth
OF goods annually, and buys only %. .O0o,'
600. The United States last year took
from Brazil Ss3, 233, $3.50 worth of coffee
rubber, sugar, hides and skins. We
sold to Brazil S14, ,710,955 worth of oul
products, but this is double the amount
sold four years ago. st. Louis Globe

Sound travels by waves radiatine
from central point of disturbance
just as waves radiate when stone i
dropped into still water. So far as tht
hearing of each individual is concerned
these waves move in direct line from
the cause of the sound to his ear, thu
impact being the greatest in the ea1
nearest the source. This being the case
a person who has totally lost the sens'
of hearing in one car, although he may
imagine that the defect is of little con
sequence, cannot locate the direction o
sound to save his life, even when tn
center of disturbance is quite near.
