New York.-The secret of Mars may
be read in 1924 when the red planet
makes its closest approach to earth,
although astronomers are skeptical Of
the theory of Marconi that the Mar
tians are signaling us by wireless,
and take no stock in the G0-fOot whirl-
Ing dish Of quicksilver which it is
promised will magnify the power Of
vision to 100000 times its normal
strength.
In 1924 Mars will come within about
B5.O0O000 miles of the earth. Be-
cause of its eccentric orbit compared
to the more nearly circular one of the
earth, Mars approaches that close only
once in fifteen years.
In 1924 observatories will be much
better equipped to study Mars than
they were in 1909, when the planet last
appeared ut its biggest and reddest in
our sky. In 1924 Mars will be the
cynosure Of telescopes all over the
earth. The 100-inch Hooker telescope
at Mt. Wilson, and the marvellous
instruments and methods for analyz-
ing light which are in use there. may
definitely solve the question whether
Mars is inhabited.
AS the distance of Mars from the
earth varies from 100000 to 2S4,-
100000 miles, the wireless signals from
that planet, if there are any, will have
a better chance to register in 1924
over the comparatively brief span of
B5,00O000 miles
Those Signals" From Mars.
For the last 20 years Mars has
been reported frequently to be at
tempting to signal to us by wireless
rays, by flashes of light, and even, ac-
cording to some imaginative specu-
latistS, by writing sign messages of
planetWide size over the ATTITUDES by
means of the Mars canal system. 1t
has even been suggested that we ac-
knowledge receipt by forming words
In vegetation over the blank of the
Sahara desert.
The MarCOni wireless communica-
tion theory is more plausible than
any of the others, because that great
inventor reports that he has picked
up wireless waves 100 miles long,
while the greatest produced on earth
by artificial means are about ten
miles long Many ways Of explain
Ing this have occurred to skeptics, but
the Marconi signals have more in
them to interest conservative sCien-
lists than any of the previous types.
There was sensation In 1900 when
1t was reported that signaling from
Mars had been detected at the Lowell
observatory at Flagstaff, Ariz This
was based on a misunderstanding of
a telegraph message concerning some
projected lights over the rim of Mars.
Instead of presenting a perfect out
line Mars showed slight excrescences
of light. These were calculated to
be from II to 30 miles above the sur
face of the planet.
Similar Projections From Moon.
Similar isolated projections of light
had been seen on the moon, but this
was easily discovered to be the sun
light tipping the mountain tops, an
effect visible on earth in mountain
Gus country when the rising sun gilds
the SUBMITS when the lower parts
Of the mountains and the valleys are
still in darkness.
But Mars has no mountains. ac-
cording to general agreement among
observers 1t was believed also to be
almost clOudless. The occasional
high lights, however, are now agreed

TO occur, though somewhat rarely.
Electric currents which apparently
wander through eternity hit the earth
here and there, causing a mysterious
kissing and cracking in wireless APP

man electrical contriyances, as the
great magnetic storm Of last May did
