The forests of Germany cover about
34,350, 900 acres, or one-fourth of the
whole area of the empire, of which
about 100000 acres are crown prop

munities AMI corporations and 17,000,>
900 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

THE Greenland whale never has
teeth but once, and that is when it is
born,' said a New Yorker who was
formerly a whaler. "Those teeth are
milk teeth, and when the young whale
is weaned they do not fall out like
baby's milk teeth but disappear by
absorption in the jaw, and instead of
being replaced by permanent teeth,
plates of beleen, or whalebone, are sub
stituted for them. IN. Y. Sun.
Japan produces an average of 49,
100000 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-
ton of barley averages 80, OO9 900 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 1892 the shipments
were 12,500,000 pounds less than in
1891. The reason assigned in the col
Uny 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,
then 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 a physician in cold blood has
observed that fully three per cent Of
the women are mustach I'd. What dc

Some extraordinary experiment
are reported from Berlin Of the eXplo
