age products in the Argentine last year
did not fall short of sa02, 900, 600. and the
net proceeds are at least half this sum.
This, of course. includes what is used
in home consumption, as well as the
exported for products
In British Guiana no suitable agri-
cultural people have settled in the
colony, outside of the sugar planters,
while its agricultural capabilities arc
enormous There is plenty of good
land suitable for cocoa, coffee, cotton
and rice, the latter being imported in
large quantities from India
There was a falling off in the value
of both the imports and exports of
France during last year. The imports
were to the value of 4, 412, 800, 900 francs
against 4, 767, s67, 900 francs in 1891, and
the exports s, 562, 900, 600 francs, as COM
pared with 1860, 737, 900 francs in 1891.
The great durability of teak, the
most valuable of East India timbers, is
due in large measure to the presence
of an essential oil in the wood, which
is in only slight degree volatile while
in its original condition in the pores,
though somewhat more SO after being
extracted.
On single day recently the Sicily
islands sent to English markets ten and
half tons of flowers This striking
fact shows the amazing progress of an
industry which was unknown q dozen
years ago in the little archipelago. The
inhabited islands contain only between
three and four thousand acres alto
gether.

of the museum of Ghizeh, and now
professor at the Sorbonne Heliopolis

with it a twin city, with the Nile be-

On the reopening of an old mine at
Bangor, Cal, a few months ago. flies
were found in dry slope connecting
two shafts, all white except the eyes,
which were red, and white rattle
snake was killed. The animals had
lived in the dry passages, where they
had been supplied with air but not
with light A few of the flies, exposed
to light in glass case, recovered their
proper color within a week-Popular

A clever chemist has invented an
automatic sensitive paint, which is a
bright yellow at the ordinary tempera-
ture, but upon being brought into a
warmer atmosphere, it changes color
gradually, until at 220 degrees, it be-
comes a bright red. 1t returns to its
original color upon cooling and may be
heated with the same effect over and
over. 1t is suggested that this paint
may be used with advantage to detect
rise in the temperature of the frac-
tional working parts of machinery.
The twenty-six-inc h-lens, which has
long been the pride of the astronom-
ical circles of Washington, has been in
use for the past eighteen years, and
was at the time of its manufacture the
largest in the world. 1t was made by
Fell, the French optician, who had a
world wide reputation for his glass
castings, and was ground and polished
by Alvin Clark & Sons, the great Amer
lean instrument makers of Cam bridge,
Macs. There were made nineteen casts
before the perfect glass was secured,
and the Clarks were nearly three years
in grinding and polishing it after it was
received. Washington Post
There can be no doubt as to the OK
istence of diamond in meteoric iron
This is the first time that this precious
stone has been found in what may be
considered its primitive gangue. In all
the rocks where it has been hitherto
met with, even in the pegmatite OF
India, we may see that it has been in
troduced as such during the formation
of the rock. Here, on the contrary, the
very state of the diamond, which APP
pears as fine powder disseminated in
certain parts of the meteoric iron, seems
to indicate that it has taken its origin
on the spot, and has been formed during
the consolidation or the crSstalization
