SCIENCE AND INDUSTRY.

Some estimate of the wonderful
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 305, 900 tons, exclusive of shellfish.
"A number of respectable Free State,
South Africa, farmers are trekking
(moving by wagon, as our own pioneers
did before the railroads were built into
British Bechuanaland, where they eX-
pect to better their condition by having
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 Dr.
Koenig, who made this discovery, is
highly elated, since no other meteorite
is known to contain stones of the kind.
The common mustard, Sinapis 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 a 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 the South is the 'screwmen"
of New Orleans. Their business is to
screw or tightly store cotton in YES
sells, to prevent shifting at sea and econ
omize space. There are / 1000 mem bers,
their dues amount to $50, 900 annually,
they own their Westinghouse, and have
$l25, 900 in bonds and securities. Their
wages are 81 day.
| When the atmosphere contains
eighty-five 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-five per cent. of hui
midity it does not mean that the atmos-
phere is only ten points away from sat
urated, but that it contains seventy-five
per cent. of the eighty-fve 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 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 a
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 fiue 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. G. M. 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 rapid de-
velopmept often occurs.

It produces pressure upon every spot
equal to the weight of the whole col.
umn above. The pressure amounts tc
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 column of air thai
will weigh 200 or 800 pounds. We are
not conscious of this, because there j!
an equivalent pressure underneath the
hand to support it. r.
The production of condensed mill
in Norway is annually increasing. Th'
value of last years exports is estimated
at about S542, 900. The following fig
ures show how steadily the export
have grown in the last twelve years
1879, 1925 pounds; 1880, 955, 75O pounds
1881, 963, ,94S pounds; 1852, 924, ,299 pounds
a slight falling off from the previou
year, but more than made up in 1888
when the export amounted to 1882, 10
pounds; 1884, 1884 $50 pounds; 1885,
1889, sos pounds; 1856, 2, 375, 797 pounds
1887, 3,797,659 pounds; 1888, 1858, 80
pounds, and 1885, 5,2S4, 702 pounds.
