Mexico buys So per cent OF all her I'M
ports from the United States, n sells
so per cent of all her exports to the n
ted States.
In Liverpool alone there are four
shops that sell American boots and
shoes exclusively, and half a dozen 9TH
ers that make a specially of them.
Bricks in Cape Town cost $50 a thou
sand for a quality so poor that they
have to be covered with plaster to keep
them from being disintegrated by the
weather.
A violin without a sounding-boX has
been invented by Mr.. Stroh, an eminent
scientist, of London, a diaphragm n
trumpet being used to give volume to
the sound.
The soil of Ecuador is so friable n
rich that rice is planted in holes made
with a machette, there being no pre-
vious preparation nor subsequent cul-
t"ivation of the ground.
Completed interurban electrical roads
in the States of Ohio and Indiana are
now averaging $4,975 per mile per
annum. The cost of operating them Is
stated as 90 per cent OF the gross re-
ceipts.
The most surprising property Of
aluminium is it's newly discovered pow
er Of giving a fine, razor-like edge to
steel cutlery. Magniied a thousand
times, the knife edge produced on the
ordinary milestone appears rough and
jagged, while that welded by the
aluminium sharpener is straight and
smooth.
A remarkable magnetic focus in the
Hebrides, at the entrance of Loeb Roag,
Lewis, has been surveyed by Captain
A. NJ. Field. The area Of disturbance
Is small, and the maximum deviation Of
the compass needle is eleven degrees
west, over one hundred feet Of water.
Contrary to what is usually true in
northern ATTITUDES, however, the north
point Of the needle is repealed from the
apparent magnetic line instead of be-
ing attracted towards it.
Following out the suggestion offered
by the friction wheels Of coming and
paper-making machines, Ludwig Maui
rer has, after many years of effort, sue
cessfully applied the friction principle
In the transference Of power in auto
mobiles. The vehicles, manufactured
in old toy-making Nuremberg, in which
Maurer's invention is used, can be run
with u%nchanging speed on a level or
up a hill by merely manipulating a fric-
tion wheel, sliding upon a shaft, which
presses against the face Of the fly
wheel supplying the power. The motor
being run at uniform speed, the speed
of the vehicle is governed by shifting
the position of the friction wheel.
For twenty years the assertion of DR..
Aitken, based on a series Of beautiful
experiments, hat clouds cannot form
In the air without dust particles to
serve as nuclei for condensation, has
been accepted, but now DR.. Aitken
himself has made a little sensation by
d%isprOving his own previous statement.
He has found that certain gases, such
as hydrogen peroxide, sulphureted by.
drogen and chlorine, when present in
the atmosphere, are converted by the
action Of sunlight into nuclei, upon
which cloudy condensation can take
place. Accordingly, although dust is
ordinarily necessary for cloud forma.
tion, yet clouds may form in dustless
air miles above the earth. 1t should be
added that when his original conclusion
was published DR.. Aitken admitted the
possibility that sunshine might create
gaseous nuclei, but he has only recently
established the fact that it does.
