Improvement from accumulated expert

blades have been brought out, there
has been no tendency TO evolve an ac-
curate theory or scientific design Such
anomalies as the variable running OF
duplicate propellers are stlll unex.
planned. The lack Of progress is at
tributed to the reticence OF sea going
engineers, whose practical observations
seldom reach constructors.
The vomiting OF fishes from volcanoes
Is no new experience, and II seems more
startling than mysterious NJ. j. Girar-
din explains that in the interval be-
tween two eruptions- latter century or
more-the craters become filled with
fish stocked lakes, and the next erup-
ton blows out the water and It's con-

A French industry Is the conversion
OF old shoes into a paste which Is trans

Recently addressing British engineers
on "Electrons," Sir Oliver Lodge traced
the modern theory TO Clerk Maxwelrs
prediction in 1873 that a better ac-
quaintance with electric discharges In
rarefied gases would throw light on the
nature OF electricity as well as on that
OF gases and the medium filing space
Since then the study of such discharges
by Sir VIM. Crookes. Prof j. j. Thorn
son and others has gradually developed
the idea OF the electric atom, or cleo
iron. The electric atoms are solid par
ticles much smaller than atoms Of mat
ter, and they are supposed TO give cleo
tric currents by rapid motion, magnetic
fields by rotary motion, and the phe-
nomena called radiation BY the waves
they emit when In vibration. There
Is reason to believe that even matter
itself may prove to be an electrical
phenomenon. with atoms made up OF
aggregations OF electrons. These cleo
trio atoms exist In space, they produce
the aurora borealis and magnetic
storms. and their rapid passage gives
incandescence TO lamp filaments.
Comparing the maps Of Mars, from
that published by Beer and Nader In
1910 70 that published by himself In
1901. Mr.. Percival Lowell finds three
periods Of development In what We see
on thai planet. In 1910 to 1876. large
dark and light markings were shown;
in 1877 to 1892, canals" in bright re-
gions were seen. and in 1893 to 1902. the
canals" were detected also In the dark
regions. The maps. agreeing funda-
mentally, show a gradual detection OF
detail In surface markings.
Living organisms have resumed their
functions after enduring the cold OF
liquid air for six months. II is sug-
gested that the remarkable experiment
should be continued for years or a
generation, for our theories would be
greatly modified by an indefinite re-
tanning Of vitality. and probability
would be given Lord Kelvin's specula-
ton that life may have reached the
earth from space.
The red deer of New Zealand are es-
timated to number between 1000 and
5000 individuals, the offspring of two
stays and six kinds that were turned
out In 1865.
Individual struggle for existence is
not The leading factor OF evolution In
Prince Krapotkins view. His new
work seeks TO show that mutual aid
has played far more important part
and points out that most animal species
live In societies, uniting IN defence
against all unfavOrable natural condi-
tons, The most numerous, prosperous
and progressive animal species are
found TO be THOSE in which individual
struggle Is most reduced and mutual
aid most developed. Human progress
In arts and intelligence has depended
on mutual aid, and the periods when
this influence has been most active
have been those OF advancement in
science and industry.
In his balloon experiments, Mr.. ]. NJ.
Bacon has been able TO see the sea-
bottom under Clear water from height
OF 500 feet, all waves seeming to be
blotted out. with no apparent scattering
Of light from the surface. At 1000 feet
or higher. all water--whether deep or
not-seemed Opaque. Photographs taken
during the ascent on a clear day be-
came gradually blurred until at 1000
feet good pictures were made impossi-

Every animal II said to have its own
kind Of flea, sometimes several different
kinds. Many thousand specimens OF
these fleas have been gathered Ia the
unique museum OF Charles Rothschild.
