SCIENCE AND INDUSTRY.
There are in Russia 312 match man
ufactories, with an aggregate production
of 1870, 7O4, 900 matches OF these works n
per cent manufacture PHOSPHORUS
matches.
The wheat exports of India in 1891
were 4s, 800, 900 bushels, as against a.
404, 116 bushels in 1890. The 1891 ex-
ports were the largest ever known, the
next highest being 7,75S, 1873 bushels In
1886. The crop of 1892 is promising bet
ter than was formerly reported, owing to
good rainfalls coming late in the season.
British India has revolutionized the
worlds trade in cinchona bark and tea
by beginning the cultivation OF these
two products until the Indian yield has
nearly doubled the worlds supply. The
government of Ceylon has now begun
the cultivation of the Indian rubber tree.
-Photographing under water has
actually been carried out, 40 it is said.
Experiments were made in 1889 in the
Mediterranean to ascertain how far
daylight penetrated under water. In
very clear water near Corsica, and
eighteen miles from land, the limit OF
daylight was found by means of photo
graphic plates to be 1850 feet.
Europe has IL. 600, 600 beehives, and
produces 3O7, 0o0, 900 pounds of honey,
| while the United States has 100000
hives, and produces 61,0S0, 900 pounds
of honey. The largest apiarist in the
world is NJ Harbicon, OF California,
who has 5000 hives, yielding 100000
pounds of honey yearly. 1t is estimated
that bee must visit 21s, $50 flowers for
each ounce of honey gathered.
The United States is fast crowding
| Switzerland out of the watch market,
and there is no part of the world, no
matter how remote, where the tick OF
the American watch cannot be heard.
To-day American factories turn out 81,
900 watches a week. Almost the only
time-pieces imported are reporters,
stop-watches and those having special
movements, which bring high price
