"A telephone system. has recently
been patented by means of which barbed
wire fefces can be utilized between
railroad stations. farmers houses and
large ranches. The patent involves the
use of portable transmitter or tele-
phone, which can be attached to the
barbed wire at any point. and by which
messages can be received or sent to
places at which there arc regular tele-
phones
DR. Richardson, an English physi.
clan who has investigated the matter,
says that the men who work in the
Paris sewers are as healthy as the aver
age, and no other $50 men in Paris are
so free from zyinotic diseases. This
leads DIR. Richardson to ask: Do sewer
men gain an immunity from conta2ion
by their occupation, or are we at sea as
to the mode of communication of the
spreading discases?'
1T is found that a photograph can
easily be made luminous in the dark by
taking a white mount, and, after coat
ing it with starch paste, sprinkle over
it luminous powder. and press it down
firmly to make it adhere. All that is
now necessary is to make the un-
mounted silver print as transparent as
possible by coating it on the back with
castor oil, and wiping away the SUR
plus oil. BY placing this over the pre-
pared mounting card and exposing it to
daylight luminous positive is OBJ

Apples are a splendid nerve tonic.
German analysts say that the apple
contains a larger percentage of phos-
phorus than any other fruit or veyeta-
Bile The phosphorus is admirably
adapted for renewing the essential
nervous matter, lecithin, of the brain
and spinal cord. Also the acids of the
apple are of signal use for men of
sedentary habits whose livers are slug
81 h in action, those acids serving to
eliminate from the body noxious mat
ter. which, If retained, would make the
brain heavy and dull or bring about
jaundice or skin eruptions and other
allied troubles.
The startling announcement is
made that the whole range of the
Andes is slowly sinking into the carth's
crust. As proof of this La Gazette Geo
graphique says that Quito was 9,596
feet above the level of the sea in the
year 1745; in 1900 it was only $50: in
1881, 1867, having sunk 26 feet in the
fifty-fve years following 1745, and but
three feet during the thirty-one years
which interviewed between 1900 and 1881.
In 1868 the city's level had been reduced
to $500 feet above the level of the
Pacific Ocean. To sum up the total, we
find that Ecuador's capital has sunk IS
feet in l22 years. Antisana's Farm, the
highest inhabited spot on the Andes
$1,000 feet higher than Quito itself,
which is the highest real city on the
globe), ia said by the same authority
to he as feet lower than it was in l745.
