Z! The city of Toronto, Ont, counts OF
getting 125,0O0 horsepower from
Niagara Falls. although its distance
from the great cataract is w miles.
The electric current Is to be carrled
the entire distance from the genera
ting plant. which will be constructed
on the Canadian side, by cables, sup
ported on double-Dole line. -"
A singular property Of gelatine. when
spread upon glass, has lately been ex-
Derimented with by the French chem
ist Cailletet. When a thick layer OF
strong glue, that has been allowed to-
dry upon a glass surface, is detached,
it carries off scales and leaves designs
resembling those Of frost on a win
dow-pane. Polished marble and
quartz are similarly attacked. WITH
glue containing six per cent. OF alum
Monsieur Cailletet produced tiVe de-
signs, resembling moss in texture.
Hyposulthite Of soda and nitrate and
chlorate Of potash, added - the glue,
produce analogous effects. The glue
while drying exerts a powerful
mechanical strain.
Count Zeppelin. whose experiments
with q gigantic air-ship over the Lake
of Constance attracted worldwide at
tention q few years ago, has. devised
O. novel form of propellers intended to
drive light-draft boats and launches.
Instead Of operating in the water,
Zeppelin's propellers like those used
to drive balloons, rotate in the atmos-
phere. They are specially intended
for use in very shallow waters, ana
in tropical rivers which contain so
many aquatic plants that the .propel-
lar of an ordinary boat becomes
clogged with them. Boats having very
slight draft can be skinned along
with such propellers at the rate OF
several miles an hour. =,
By taking advantage Of the diffrac-
ton disks formed by the waves Of light
about bright points, .Messrs. Sleden-
topf and Zsigmondy have produced,
with q microscope, magnlfyng
power of $4,000 diameters, and 1t is
estimated that the same method may
achieve a power Of 100000 diameters.
The objects experimental with were
particles of gold, which almost ap'
proach the minuteness Of molecules,
disseminated through ruby glass.
which were rendered virtually visible
by means Of their diffraction disks
that is to say, the disks being seen,
the particles could be counted and.
their true size determined, although
they were not themselves visible In

The project Of climbing the loftiess
mountain on the earth. Mount Everest.
In the Himalayas, whose tremendous
head rises, according to trigonometri-
cal measurements, 29,002 feet above
sea.level. has now reached a stage i'm
mediately santecedent to the actual at
tempt. A. party, led by Mr.. Ecken-
stein, an experienced climber. has set
out for the foot of the great peak.
Several celebrated mountain-cliL-oers
have expressed the opinion that the
feat is feasible, but only by the metnod
of gradual ascent, whereby the adven-
turers may become Injured to the ef-
fects of rare atmosphere. Months
and even years may be spent in as
cending to higher and higher levels.

considerable advance. The highest
ascent now on record is that of Aeon.

than a mile, less than the height OF
Everest.
