India within the past ten years, and
now excellent brands of her choice
tobaccos are known throughout the
worlds markets, except in the United
States.
Mr.. G.. BONNER, professor of botany |
ut the Paris Sorbonne, disputes the |
prevalent notion that the mistletoe Is |
injurious to the apple or other tree on |
which it grows. He maintains not only |
that this is not the case, but that it is |
actually beneficial to it's host. d.
A railway beginning at Belize and |
extending to the State of Guatemala, at
or near the town of Peten, is under
contract. 1t will open up extensive
areas of lands of the most fertile de-
scription and will afford access to the
mineral regions of British Honduras
which are now beyond the reach OF
transportation.
Mr. Boys, who has recently made
some valuable experiments in photo
graphing bullets during their fight
from gun, infers that the projectile
must have received about per cent. OF
its velocity after leaving the muzzle, at
which point the turning effort Of the
rifle must have necessarily ceased.
The foot of horse is one of the
most ingenious and unexampled pieces
of mechanism in the whole range Of ami
NAL structure. The outside. hoof IL
made up of series of thin, verticle
| lamine of horn, about five hundred in
number. Into this are fitted about five
| hundred more thin lamine, which be-
long to the coffin bone, both sets being
elastic and adherent.
Canada exports annually, $4,000
tons, and the United States $4,000 toni
of cheese, equal in quality to the Cru
yere cheese of France. This, together
with the Swiss cheese, competes with
that of French make to such an extent
as to create suffering among French
cheese makers, who wish legislation
for putting stop to, or limiting the
profits of merchant and middleman.
Now that rance culture has begun
seriously to engage the attention OF
planters in the tropics, 1t Is interesting
to learn on the authority of a foreign
journal that rance fiber, under great
hydraulic pressure, may be made to as
sumo the compactness of steel. 1t is
asserted that when SO prepared 1t will
be particularly serviceable for steam
pipe, as it will not be subject to contrac-
ton or expansion and also will not rust.
in 1912 Russian farmer conceived
the idea of extracting oil from the sun
flower. His schemes were considered
most visionary, but he persevered, until
now the industry Is one of enormous
proportions, there being 100000 acres
under cultivation in Russia. There are
two kinds: one with seeds that are
crushed for oil, and second species
which is consumed by the people in the
same way that peanuts are in this coun-
try.
In consequence of the enormous in
itial velocity of the bullet in the new
Mannlicher rife and the resulting fric-
ton and wear on the barrel, it has be-
come necessary to devise some method
preventing both of these evils. The
manager of the government laboratory
at Thun, Switzerland, has consequently
devised method of inclosing the leaden
bullet in a thin metallic covering, while
, over this he places wrapper, specially
, prepared oleaginous paper, which re
duces the wear of the rifle barrel to 6
/ minimum, without interfering with the
course of the bullet.
The April number of Natural Sci
. ence contains an interesting note upor
e the Australian mudfish, about which
$ less is known than about the African
t mudfish. The latter may be seen a
r present in the reptile house at the Zoo
S and is one of the most interesting Great
S ures on view there. Both these fishe
t declined some ages ago to move witt
the times. and have remained, in conse
S ouence, about half way between a fsl
t. and amphibian. Some OF the African
t. mudfshes when they arrived at the 10

The largest paper and pulp maxim

a owners. The company has signed
w lease for 3,OOO-horse power to be fu
