France owes its wonderful success in
gardening to this system, and In late
years Italy has spent over 500, 900, 900
for this purpose.
in Manitoba, Canada, there were
1881 farmers in 1891, each averaging
1876 acres under cultivation. The aver
age price of improved land is s10.s5 per
acre, of unimproved 1926, the percent
age of land taken up by settlers was
G2.7, and the percentage fit for cultiva-
ton 74.S.

gambler to the value of 81 5000 an

The frst manufacturing enterprise
started in America is said to have been
a glass factory, which was built in zoos,

from this was exported the first North

factory soon fell into decay; but another

making glass beads for the Indians.
colorado is usually thought of only
as mining state, but with the success
and spread of irrigation she is pushing
to the front as a fruit-producing state.
A very large crop of the most luscious
watermelons in the country is raised in

Swedish iron. which is soft, yet
strong and ductile, is almost free from
phosphorus and sulphur. 1t is held to
be practically inexhaustible, though
taken ont at the rate of about million
of tons year. 1t is found all through
1,a fhN,,n1 Cd oh inH 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 Paulscn, at Cod
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

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, So per cent;
nitrous products, Is per cent, and nitro
glycerine vapor in varying quantity.
The carbonic oxide, nitrous compounds
and nitro-glyccrine vapor are very dele
terious, and their formation should be
prevented. This NJ. Charon says, can
best be done by using more powerful
detonator, say one to thirteen gramme,
instead of one-half grainme of fulminite,
thus making the combustion more per-
feet. To counterfeit 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.
