In Southern Arizona business of all
kinds is increasing in volume, and the
miniag and cattle industries are us
suming large proportions.

come from neighboring mines.

The beautiful wood mountain on

visited in the summer of last year by
Baron Won Toll, a Russian explorer.

OF the cephalopods, comprising the
cuttle fish, the octopus, or devil-fsh,
and their allies, thirty-two species new
to science were discovered by the Chal-
lengcr expedition, according to y report
just finished. Some of the ccphalopods
have Il length of sixty feet, and they
appear formidable as well as singular
creatures. -Arkansaw Trareler.
There are 90 blast furnaces in and
about Pittsburgh, IS rolling mills, 80
steel works, 10 window glass works, 81
flint-glass works and IL green glass
works. The blast furnaces make $780,
600 tons of iron per year, the rolling
mills $4,000 tons, steel works $50, 900
tons, plate glass works $, $1,000 square
feet, window glass works 100000
A remarkable proof of the protect
tive instinct of birds is reported from
South America. In Chilli the fruit of
the year is said to have caused the
death of many sheep and cattle when
fed to them in large quantities. The
birds, however, did not touch the fruit.
From this fact it is argued that the in
stinct of birds in respect to fruit may
well guide man in regard to eating it;
and the further suggestion is made that
the condition of the fruit crop of par
ticular season may have something to
do with outbreaks of epidemic disease,
such as cholcra.-N Y Ledger.
The corn-canning industries in
Maine is great one. Eighty factories
have been running there this year, and
over IA, 900, 900 cans of sweet corn have
been put up, besides large quantities of
apples, beans. tomatoes and other vcge-
tables and fruit. The sales amount to
upward of $2,000.000. most of which
goes into the pockets of the farmers
and workmen. The farmers make a
speciality of raising sweet corn, and its
said the Maine variety is much sweeter
than any other. Public Opinion.
The remarkable industrial and
commercial progress made in the South
err States during the past few years
has been widely noticed. An im-
portant feature of this is found in
the comparative freedom from labor
troubles, which in nearly every other
section of the country have caused So
much disturbance. Leading Southern
papers have recently called the atten-
ton of manufacturers and others TO
this as an inducement to embark in
Southern business enterprises, and this,
with natural advantage at the South,
has induced many to start in business
there. BrGdStreecs.
According TO recent experiments OF
MN. Hauriot and Richet, of which an
account has been given to the French
Academy of Sciences, the ventilation of
the lungs is increased by muscular
labor. In moderate work the vcntila-
lion is more than sufficient for the ex-
cretion Of the carbonic acid produced,
and above all for the absorption of the
necessary oxygen. In hard work the
: proportions of carbonic acid produced
and oxygen absorbed rise slightly the
harder the work; but it is chiefly the
proportion of carbonic acid which in
creases. During muscular exertion the
ratio of carbonic acid produced to
oxygen absorbed tends to become unity,
although normally it is less than unity.
