The miners convention at Paris
represented 100000 men.
Cuba, it is said, seems destined to
supplant Bermuda as the truck garden
for this country "Iler potatoes and
onions have already taken precedence
over those of bermuda, and now her
tomatoes are taking first prize" This
market gardening in Cuba is being
largely directed from New York
"A deposit was recently discovered
! in Citrus, Fla, which is believed to be
very rich in potash. If the analysis of
the chemist confirms the belief of this
information the discovery will be a
boom exceeding in value that of any
phosphate deposit, on account of the
scarcity of the article and the magni-
tnde of this deposit.
Natural gas has been discovered in
the Argentine Republic. DIR. Arta, a
local chemist has by analysis found it
| to be quite as rich in heating and light
ing power as that found in the United
States As the lack of fuel for manu-.
featuring purposes has been one of the
greatest drawbacks in the Argentine
Republic, this is considered of the very
greatest Importance.
| There is really but one place in the
world where violins are made extern
| sively. That place is Markneukirchen,
| with its surrounding villages. There
! are altogether about $1,000 people liv-
! ing there who do nothing else but make
violins. The inhabitants, from the lit
| tie urchin TO the old gray-hcaded man,
the small girl, and the old grand
mother, all are engaged in making some
| part of a fiddle.
| "A trainer who has had thirty
years experience observing lads and
men training, declares running in the
! open air to be the best of all exercises.
| He recommends "all around" work,
such as boxing, hand-ball, jumping and
| single and parallel bar exercises; these,
in his Judgment, being adapted to most
| naturally develop the body as whole,
and normally develop the exterior mus
cles, while at the same time benefiting
the vital organs.
The biggest of fresh water fishes,
| the 'arapaima" of the Amazon in South
America, which grows to six feet in
length, has teeth on its tongue, so that
d
as such. Some kinds of trout also have
the same popularity. Fishes that swal-
low their prey entire have their teeth
| so supported on flexible bases as to bend
backward, but not forward, in order
that their victims shall not escape after
they have been seized
AT last fish has been caught in
the Great Salt Lake. 1t was captured
near Buffalo Park, and is one and five
eighths inches long. 1t is different from
anything ever seen here before, having
| large head, body something like
! trout, while it is almost transparent,
except the dark outlines of the verteb bra,
which is as well formed as if of full
! grown fish, and is dark. There were
/ two of these small fish swimming to-
gether, and they We're so lively that
only one could be caught.
Prof. Barnard has invented trap
not to catch rats or any earthly thing.
but those tailed monsters of infnity
known as comets. He has fastened
| prism in the object glass of his tele-
scope. When the light passes through
! the prism it is decomposed, of course,
and if the light is that from a comet,
certain rays pass through Sits and fall
upon a selenium cell which connects
with battery and an alarm. Selenium
is exceedingly sensitive to light, and
when struck by the rays it lets the bat
terry know it in a hurry. The telescope
is made to sweep the heavens by auto
matte machinery.
The discussion by physicians of the
distribution of diphtheria has developed
some very interesting and curious facts.
The distribution of diphtheria is alto
gether peculiar, and it's mortality is
not apparently regulated by the same
causes that influence the general NOR
tality. Density of population is not a
factor of primary Importance in the
production of fatal diphtheria. On the
contrary, its prediction for scattered
rural populations and for exceptionally
! healthy districts, and the striking tend
ency which the disease has shown of
late to invade cities and towns, are
well-llnown and remarkable facts.
