1t is believed that shooting stars are
small, solid bodies, revolving round
the sun. AS they are travelling in a
contrary direction to the earth the
velocity with which they enter our at
mosphere is very great, on an average,
about thirty miles a second.

the United States during the twelve
months which ended January 81 last
was S9SS, ,O53, against 1864 1920, ,901
during the preceding twelve months.
The total value of our imports in the

during the twelve months preceding.
For nearly half a century Mt. Ever
est, or Gaurisacker las it is known in
Europe and Asia) was thought to be the
apex of the world. In 1881, however,
Capt. Lawson, sent out by the British
Geographical society, discovered peak
on the Isle of Papna, which is 49,
feet in height. He named it Mt. Her
culeS.
AT Grenoble, France, 1900, 900 dozen
pairs of gloves are manufactured an
nually. This represents value of ST.
1000, and gives employment to $4,000
workpeople of both sexes. There are
1000 men and 21 900 women residing in
rayon of thirty-eight miles around
Grenoble who live by this work.
The mineral output of Colorado for
| 1891 foots up $50, ,54S, 1884, an increase
over 1890 of SO ,66s, 200. Tie average price
of silver for 1890 was $1.041, while for
| 1891 it was only 9S.55. Colorado now
has 4,57S, ,S66 acres of land subject to ir-
rigation by bitches and canals, the
number of miles of which amount to
| 1896. Great confidence is felt in Col
orado for good yield this year.
Mr.. Bent, an English archeologist,
is now in Lisbon, and expects from an
examination of the archives there to
trace the remarkable people who cen

Mashonaland. At the Zimbabye ruins

at Mazoe workings a ring of very an
tique design, which is now in the pos

"A German chemist has patented a
|
for photographic purposes. The method
pursued consists in coating the glass
with bichromatized gelatine and then
transferring the Photographic print to
the sensitive surface. After metallic
| powder is busted over the parts it is ex-
posed to the sunlight, and the exposed
parts of the gelatine washed away with
| turpentine The glass can then be
deeply etched with fouric acid.
Prof. Nicholas Tesla has already sue
ceeded in producing in a room an cleo
trostatic field, into which, if a glass
tube exhausted of air is carried, the
tube will glow with light and illuminate
the room like a lamp. 1t now appears,
as Prof. Crookes says, that 'a true flame
can be produced without chemical aid
"a flame which yields light and heat
without the consumption of material
and without any chemical process" :"
Those who have studied the chemistry
of the candle will appreciate what this
means.
"A number of plants have the sin
gular power of living long time with
out water, and without any connection
with the earth. DIR. Torrey found a
root with some signs of life in a herb
arium long after it was collected, and
hence we have LeWisiG rediUiUa. The
Rose of Jericho is plant not distantly
related to the wild carrot, which draws
itself out of the ground and rolls into a
ball, driven by the winds and then
spreads, roots and grows under the first
rainfall. In Mexico, Arizona and Texas
is club moss (Selaginella IepidophyIla),
which also dries into ball, and is sold
In curio stores as the Resurrection
plant" It develops in earth or water
after six months drying, just as well
as if nothing had happened.
