value of the fishing industry of Great
Britain can be gained from the state
ment that the total catch of fish on the
coasts of England and Wales in 1890
was 3o5, 900 tons, exclusive of shellfish.

South Africa, farmers are trekking

British Bechuanaland, where they ex-

more room and pasture for their sheep,
and other advantages.
| One of the two massive meteorites
found recently by Prof. Foote, of Phila-
delphia, in the Canon Diabolo, Ari., was
discovered to contain cavity, in which
were several small diamonds. DIR.
| koenig. who made this discovery, is
highly elated, since no other meteorite
is known to contain stones of the kind.
The common mustard, Snaps nj
gra. takes possession of abandoned
fields, and soon crowds out everything
else So vigorous is it there that it is
frequently tall enough to hide horse
with it's rider California could supply
the world with mustard seed only for
the black aphis, which everywhere COW
ers flower buds and fruit.
One of the strongest labor organ
izations in che South is the "screwmen"
of New O leans. Their business is to
''scrcw" or tightly store cotton in YES
sells, to prevent shifting at sea and econ
| omiZe space There are 1000 members,
their dues amount to 5000 annually,
they own their Westinghouse and have
| Sl25, 900 in bonds and securities. Their
wages are 81 a day.
When the atmosphere contains
eighty-fve per cent. of moisture it is
saturated; the amount of humidity is
calculated on the eighty-fve per cent
scale, so that when we are told that
there is seventy-fve per cent. of hui
Nudity it does not mean that the atmos-
! phere is only ten points away from sat
uratcd, but that it contains seventy-fve
per cent. of the eighty-five per cent of
humidity necessary to saturate it.
There is no doubt but the form of
roof has much to do with the draught
! of a chimney. The fat roof offers no
resistance to the passage of air, but as
the pitch is increased the current is
more and more disturbed, until, with T.
high pitched and many-gabled roof it is
broken into innumerable eddies, some
OF which are sure to curl down and force
the smoke and gases in the flue into the
rooms below. Chimneys on such roofs
should be built higher than ordinarily.
The preliminary results of some in
vestigations upon the growth of the
face are stated by Prof. e. NJ. West, in
| Science. The values obtained in the
case of measurements of the female face
point to the existence of three distinct
periods of growth: the first ending at
about the seventh year, and the third
| beginning at about the age of fifteen.
| The abrupt transition from one period
to the next is indicated by the very slow
growth of some children until the ages
of eight or fourteen, when a rapid de-
velopment often occurs
The height or distance ~ the at
mosphere from the earth, TO which it
extends is not definitely known. 1t is
variously estimated at 100 to 500 miles,
1t produces pressure upon every spot
equal to the wei .ht of the whole col
umn above The pressure amounts to
about fifteen pounds upon every square
inch. Since the pressure of air is evenly
balanced upon all sides we are not con-
scious of it. Upon the outstretched
hand there rests a column of air that
will weigh 200 or 300 pounds. We are
not conscious of this, because there is
an equivalent pressure underneath the
hand to support it.
The production of condensed milk
in Norway is annually increasing. The
value of last years exports is estimated
at about $542, 900. The following fig
ures show how steadily the exports
have grown in the last twelve years:
1879, 1928 pounds; 1880, 955, 80 pounds;
1881, 963, 946 pounds; 1882, 924 ,299 pounds,
slight falling off from the previous
| year, but more than made up in 1883.
when the export amounted to 1882, 159
pounds: 1854 1851, $50 pounds; 1885,
1,7S9 sos pounds; 1886, 2,375, 797 pounds;
1887, 3,797,G59 pounds; 1855, 1858, 800
pounds and 1889, 5,2S4, 7O9 pounds.
