The star. (Reynoldsville, Pa.) 1892-1946, 1903-09-02

The city Of Toronto, Ont, counts on
getting $4,000 horsepower from
Niagara Falls, although its distance
from tn. great cataract is 90 miles.
The electric current Is to be carried
the entire distance from the genera
ting plant, which will he constructed
on the Canadian side. by cables, sup.
ported ON a double-pole lire.
A singular property Of gelatine, when
spread upon glass. has lately been ex-
perimented with by the. French chem
ist, Cailletet. When thick layer OF
strong glue, that has been allowed to
dry upon a glass surface. is detached,
Il 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 five de-
signs, resembling moss In texture.
Hyposull .bite of soda and nitrate and
chlorate OF potash, added . the glue,
produce analogous effects. The glue
while drying exerts powerful
mechanical strain.
Count Zeppelin. whose experin ents
with a gigantic air-sbip over the Lake
of Constance attracted worldwide at
tention few years ago, has devised
novel form of propellers intended to
drive light-draft boats and launches.
Instead of operating in the water,
Zeppelln's propellers. like those used
| to drive balloons, rotate In the atmos-
phere. They are specially intended
| for use In very shallow waters. and
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 or
| several miles an hour.
By taking advantage Of the diffrac.
tion disks formed by the waves of light
about bright points, Messrs. Sieden-
| topf and Zsigmondy have produced,
| with microscope, magnifying
power of $4,000 diameters, and 1t Is
| estimated that the same method may
achieve n power OF 10000 diameters.
The objects experimental with were
particles Of gold, which almost mp
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
dependent of the disks.
| The project of climbing the loftiest
mountain on the earth, Mount Everest,
| in the Himalayas. whose tremendous
head rises, according to trlgonometri-
| cal measurements, 29,002 feet above
sea-level, has now reached a stage I'M
mediately antecedent 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-climbers
have expressed the opinion that the
feat is feasible, but only by the method
of gradual ascent, whereby the adven.
turers may become Injured to the eff
fects of rare atmosphere. Months
and even years may be spent in as
cending to higher and higher levels,
q long pause being made after every
| considerable advance. The highest
ascent now on record Is that Of Aeon
cagua, in the Andes. the elevation OF
which Is 230S0 feet, 1922 feet, or more
than mile. less than the height Of
