The forests Of Germany cover about
"a, $50, 900 acres, or one-fourth of the
whole area of the empire, of which
about $4,000, 600 acres are crown prop
erty. 100000 acres belong to COM
munities and corporations and 17,000,-
200 acres are owned by private per.
sons.
American pig irons are gradually
displacing the English and Scotch
products in central and western Can
ada. AT Montreal, where the foreign
irons are landed, they have the ad-
vantage in price, but when the cost of
land transportation is added it becomes
impossible to sell it in competition with
American iron made in Ohio and Penn
sylvania.
1.-THE Greenland whale never has
teeth but once, and that is when 1t is
BORN" said New Yorker who was
formerly n whaler. s'Those teeth are
milk teeth, and when the young whale
is weaned they do not fall out like a
bnby's milk teeth, but disappear by
absorption in the jaw, and instead of
being replaced by permanent teeth,
stituted for them. IN. Y. Sun.
Japan produces an average of 49,
600, 900 bushels of wheat from 1000, 900
acres every year. Though it imports
very little wheat, yet the quantity is
gradually increasing, while the exports
are diminishing. The annual produc-
tion of barley averages 100000 BUSH
els, the imports in this case also show
ing tendency to increase and the ex-
ports to decrease.
1T looks almost as If the export of
frozen meat from New Zealand had
reached it's limit, at any rate for the
present, because in 1899 the shipments
were 12,5OO.OOO pounds less than in
1901. The reason assigned in the col
ony is that there has been such an un-
usual demand for live stock, to stock
new land that is being opened up, that
this trade has paid better than ship
ping for export If this be the case,
chen we may look for even heavier
shipments within few years.
"A learned German scientist makes
the astonishing announcement that
among women mustaches are COM
moner in the present day than they
used to be in the past, In Constanti-
nople one out of every ten women have
unmistakable evidences of down on
their upper lips. A similar proportion
of mustached women'is to be noticed
among ladies in Madrid. And in Phila-
delphia physician in cold blood has
observed that fully three per cent. OF
| the women are mustached. What do
these facts indicate? A certain Mr..
Mott thinks they indicate the improve
ment of the human race, for, according
to his theory, the race is destined
eventually to be completely covered
with hair.
Some extraordinary experiments
are reported from Berlin of the eXplo.
sive which is to replace the powder al
present in use in the German army
The new explosive is greasy sub
stance of brown color, of the consis
tency of frozen oil. 1t does not explode
by blows or shocks and if thrown on
the fire burns slowly with blush
flame. 1t only eXplodes by the intro
duction of certain substance, which
is the secret of the inventor. The re

effect is said to be nine times that o.
powder. A quantity not larger than {
poppy seed of the substance which
causes this explosion is sufficient, ant
it is inserted into the cartridge by
means of needle.
1t has often been proved that dogs
are able to track their masters through
crowded streets where it would be i'm
possible to attribute their accuracy tt
anything except the sense of smell
alone. A naturalist once made som,
interesting experiments as to thi
power as exhibited in his own dog. II
these tests the naturalist found tina
his dumb friend could easily follow il
the tracks of his master though he wa
far out of sight, and that. too, after nj
less than eleven persons had followed
stepping exactly in the tracks made b,
his master, it being the deliberate in
tention to confuse the senses of th
dog, if possible. Further experimen
proved that the animal tracked tn
boots instead of the man, for when tn
naturalist put on new footgear the do!
failed entirely.
