In this country 1000, 900 acres o.
land are being farmed by irrigation.
France owes it's wonderful success il
gardening TO this system, and in late
years Italy has spent over $500, 000,0
for this purpose.
In Manitoba, Canada, there were
1897 farmers in 1891, each averaging
7s.5 acres under cultivation. The aver
age price of improved land is s10s5 per
acre. of unimproved 1896, the percent
age of land taken up by settlers was
62.7. and the percentage fit for cultiva-
ton 74.s.
Gambler is the second largest vege-
table product of the Malay peninsula.
1t is most important tanning material,
is used as brown dye, as medicine
and in silk works England imports
gambler to the value of 81. 100000 an
nually, and our American imports are
close to 81, 100000.
The first manufacturing enterprise
started in America is said to have been
a glass factory, which was built in 1908,
about mile from Jamestown. Va, and
from this was exported the first North
American manufactured product This
factory soon fell into decay; but another
was built in 1921 for the purpose of
making glass beads for the Indians
Colorado is usually thought of only
as a mining state, but with the success
and spread of irrigation she is pushing
to the front as fruit-producing state.
A very large crop of the most luscious
watermelons in the country is raised in
Colorado, and the product is of such i'm
portance that watermelon day is spe-
cial holiday all over the eastern portion
of the state; the governor usually at
tends the festivities at the watermelon
growing center and excursionists at
tend in thousands. This year Colorado
has produced 100000 quarts of straw
berries.
strong and ductile, is almost free from
phosphorus and sulphur. 1t is held to
be practically inexhaustible, though
taken out at the rate of about million
of tons year. 1t is found all through
the country, though mined chiefly in
central Sweden, in the Dannemora dis
trict. Several of the heights as truly
deserve to be called iron mountains as
those in Missouri and there is one in
Gellivare, in Swedish Lapland beyond
the Arctic Circle, where the ore occurs
in four gigantic strata, that would sup
ply nearly all the iron that the country
would require in century. Minerals
Experiments made at the Royal
Danish Academy have demonstrated
approximately the height of the aurora
borealis NJ Adam Paulsen, at God
thaab, by means of two theodolites
situated four miles apart, found that
different aurora displays varied from
one to four miles in height Expert
ments near Cape Farewell showed the
height Of different auoras to vary from
one to ten miles. At Spitzenberg the
range of height was from one-third to
eighteen miles In some of the earlier
experiments in this direction the OBJ
servers concluded that the height of
auroras varied from ninety to five hun
dred miles.
In recent number of lie Genie
Civil, NJ. p. f. Charon says that the prod
ucts of combustion from charge of
dynamite have been found to be approx
imately: Steam, 10 per cent; carbonic
oxide and carbonic acid IS per cent;
nitrous products, Is per cent, and nitro
glycerine vapor in varying quantity.
The carbonic oxide, nitrous compounds
and nitro-glycerine vapor are very dele
terious, and their formation should be
prevented This NJ. Charon says, can
best be done by using a more powerful
detonator, say one to thirteen gramme,
instead of one-half gramme of fulminite,
thus making the combustion more per-
feet. To counteract the effects of the in
| furious fumes the author recommends a
draught of strong, pure coffee and the
inhalation of ammonia, sulphurous acid
or concentrated acetic acid.
