If Southern California are situated in
Los Angeles and Ventura counties, and
they occupy an area of $50, 900 acres.
This important product is rapidly be-
coming one of the most valuable in
Southern California, the yield for 1889
aggregating in value over 81, 100000.
The first consignment of fresh sal
mon from British Columbia to Europe,
which consisted of $4,000 pounds from
Frazer river, left New York the other
day for Hamburg in a cold storage COM
partment of German steamer. Frozen
salmon from Canada have often been
sent to England, but this is the first
cargo from the Pacific Coast, and if the
experiment proves successful very
large trade will result The rivers of
British Columbia yielded nearly 11,0Oo,-
900 pounds of salmon during 1891, ale
though it was reported as bad year

A few years Cgo it was suspected
that the latitude of places on the earth's
surface changes A number of astron-
omers agreed to make observations for
two years, and the result has just been
made public. Latitudes do change
Berlin, for example, was fifty feet
nearer the north pole in September
than it was in March. This change is
not, of course a shifting of any one
point on the earth's surface. 1t is
fitting of the axis of the earth.
1t would require the intellect of a
Babbage to wrestle with the statistics
of matches That so, 900, 900 are burned
every day in Europe seems below the
mark. Such firms as Messrs Dixon, at
Manchester, turn out 9, 600, 600 day, and
many in London 1900, 900 or 5000, 600.
The consumption of phosphorus for the
purpose in England and France shows
that about $50, 900, 900, 900 a year are
turned out in these two countries alone.
1t is we'll known that horses can
hear deep sounds which we cannot For
days previous to the earthquake in the
Riviera, the horses there showed every
symptom of abject fear, which continued
without any change of character till the
fury of the convulsion broke forth. But
not till few seconds before the earth be.
gan to quake did human beings hear any
sounds, while it is extremely probable
that the horses heard the subterraneaD

furious at their maximum time OF
growth, which corresponds with the
full of the moon; but when the moon
wanes, they become poor and often
poisonous. The poisonous quality ap.
parently results from the death of large
numbers of them at this time and the
putrefaction of their bodies yielding
ptomaines, which are absorbed by the
surviving mollusks.
The Railway Review tells of a
novel method of laying foundations in
swampy soil recently employed by ar
American engineer. The building tC
be supported was a low wooden one
which it was proposed to use for the
storage of machinery. Casks were SCI
in holes in the ground along the line o.
/ posts and were filed to the depth O.
: about one foot with iron turnings The
posts were placed in the casks. which
were then filed with iron turning'
compactly rammed in place. A solution
/ of salt and water was slowly pouret
over the turnings under the action o
which they solidified into hard mass
The heat of the oxidation of the iroI
was SO great that the posts wer'
> charred This also served to act as
preservative, and to that extent th'
I iron turnings are probably superior t.
