-Hhe total production of white lead
in the world is about $50, 900 tons per
annum. of which the United States pro
duces about one-third.
The old theory that the deepest
place in the ocean will be found to cor
respond almost exactly with the height
of the highest mountain has been dis
proved by measurements taken within
a year, which show ocean depths 10, 900
feet deeper than the highest mountain
peaks.
An experiment of Marcy's proves
that mastication will accelerate the
flow of blood through the carotid artery
and serves to show the wisdom of an
editor who used to eat figs while writ
ing a leading article, and even of those
who INDUCED in the practice so dis
agreeable to their neighbor of chewing
tobacco
The difference in the height of the
perpetual snow line is due to tempera-
ture. The western slopes are warmed
by warm winds from the Pacific Ocean,
the eastern slopes by land winds, hence
the difference. In the Himalaya noun
tains the difference in the altitude of
the snow line on the two slopes is still
more apparent
The potato crop in Jersey has not
been as profitable to growers this year
as last The average crop for ten years
past has been 2,072, 900 bushels, worth
1850, 900 annually. The 1892 crop was
2,4S4, 900 bushels, only 1880 less than
in 1891, but its value to farmers was
81, $50 900, as compared with 81, 44o, 900
for the 1891 crop.
In British Guiana magnificent tim
Der covers thousands of square miles
some of the woods being very handsome
and suitable for best cabinet work.
while others are very valuable for
works of public character. There is
plenty of good land suitable for cocoa,
coffee and cotton, and no agricultural
industry is carried on except sugar
culture.
The hair on the ordinary doll Is
made from the hair of the Angora goat;
this product is controlled by an English
syndicate and is valued at $40, 000, 900 n
year. After the hair is prepared it is
sent to Munich and made into wigs by
girls, who receive twenty cents dozen
wigs Human hair is used only for
what are known as the last dolls"
that is, dolls for big girls, who like to
do up their dolls hair in the latest style.
In Queensland, there are 1000 acres
of land under cotton cultivation, and
farmers everywhere are turning their
attention to it's further growth. Owing
to excessive rain the season has been
against them, but in some cases a ton
of cotton per acre was secured, the
quality being pronounced excellent by
local experts in the colonies, who also
claim that it is much superior to ordi-
nary American cotton.
To form some idea of the largeness
of this earth, one may look upon the
landscape from the top of an ordinary
church steeple, and then bear in mind
that one must view 900, 900 similar land
scapes to get an approximately correct
idea of the size of the earth. Place 500
earths, like ours side by side, yet Sat
urn's outermost ring could easily en-
close them. Three hundred thousand
earth-globes could be stored inside Of
the sun, if hollow.
"A Mons. Moricourt has invented a
process for metalizing textile fabrics,
whereby it is claimed that they are
rendered proof against the attacks of
microbes. The materials, wool, flannel,
calico, etc, are immersed for about an
hour in an ebullient bath composed of
kilogrammes of sulphate of copper,
kilogramme of sulphate acid and 1000
liters of water. On removal from
the fluid the fabric is calendcrcd
and dried. The finish thus obtained
will, it is said, bear two or three wash
ings before it is again required to sub
| ject the cloth to the metalizing opera

Bees are very fastidious in the mat
ter of smells; they appear to object
to the human breath, especially
that of persons recovering from illness;
therefore, TO approach hive with
safety be cautious how you breathe.
1t is probably chiefly by the sense of
smell that bees and ants recognize
their friends-that is, the members Of
| the same hive or colony-for bees
sprnkled with scented sirup and then
introduced into strange hive will not
be molested, as other intruders invaria-
