that life exists on Mars and expect to
prove it with the novel telescope. What

LUweh Says Surface of Mars
Is Level and Undressing
Lowell has said that Mars ia level
and uninterestine, with no mountains
and only a few dried-up beds q shsl.
low seas to diversity its topography.
More than one-half of it s desert land
and the rest is only green when the
canals are bringing water from the
polar ice caps. Dust storms. which
blot out hundreds Of square miles Of
the planets surface from TIE view Of
scientific observers, sweep over its
equatorial section.
The physical conditions Of Mara ara
entirely different from those we know
on earth. The force Of gravity ex-
erted by Mars is only three-e ghths
that of the earth, while the atmospheric
pressure that is about fifteen pounds
to the square inch at sea level on orr
world is less than four pounds on Mara,
according TO scientists. The air Is
very thin and no known animal could
live on it. These conditions, however,
make it possible for great weights !"
be lifted with little effort.
Lowell computed tat .he Marsiafs
could DO seven times more work than
human beings could accomplish, with
the same amount Of effort. 4 human
