In 1924 Mars will come within about
100000 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 we're in 1909, when the planet last
appeared at 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 35,000,000 to 1884,
100000 miles, the wireless signals from
that planet. if there are any, will have
better chance to register in 1924
over the comparatively brief span of
100000 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
planet-wide 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

The MarcOni wireless communica-
ton 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 slleptics, but
the Marconi signals have more in
them to interest conservative scien-
lists than any of the previous types
There was a 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 perfect out
line, Mars showed slight excrescences
of light. These were calculated to
be from II to 80 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

of the mountains and the valleys are
still in darkness.
But Mars has no mountains, &C.
sording to general agreement among
observers. 1t was believed also to be
almost cloudless. The occasional
high lights, however, are now agreed
to have been clouds which are thought
to occur though somewhat rarely.
Electric currents which apparently
wander through eternity hit the earth
here and there, causing q mysterious

rents, called "strayS" or "atmosphe

preted as signals from Mars, when
Trey came with regularity that
seemed ito be directed by human
intelligence. But they have been
nected with sun spots.
The scheme, attributed to d. David
Todd of Amherst, well-known as
tronomer, of using great abandoned
mine shaft in Chileefor the making of
a colossal telescope, has been the sub
]ect of no little scientific discussion.
ms shaft, which is said to have u
W-foot diameter, is located near the
equator. 1t is therefore, in the plane
on which the earth and all the other
planets whirl round the sun. The
shaft telescope has the disadvantage
mat it could never be shifted, and
could only be used for that part Of
the heavens which passes over it. But
II is calculated that Mars will pass
sSIrectly over it when 1t becomes big,
