1898 Excerpt: ...some conception of the appearance presented may be
formed. From the appearance of the country round Mount Hamilton as
seen from the observatory, it was possible to imagine that, as
viewed from a great altitude, this region, broken by canon, slope,
and ridge, would closely resemble the surface of the Martian seas.
During the observations the conviction seemed to force itself upon
the observer that he was actually looking down from a great
elevation upon just such a surface as that above which the
observatory was situated. It appears, therefore, that if water
exists at all upon Mars in the liquid form, it must be sought
elsewhere than in the so-called seas; and it is possible that, in
an observation made in 1894 by Mr. Lowell and Professor Pickering,
its place upon the surface of the planet was revealed for the first
time. During a careful study of Mars, when near its opposition in
that year, with the aid of a fine refracting telescope of 18 inches
of aperture, there appeared a dark belt forming a fringe to the
south polar cap. The belt first appeared after rather more than a
Martian month following the spring equinox of the planet. It was
estimated as being the darkest marking on the disc, and appeared to
be of a decidedly blue colour. As the polar cap dwindled, the belt
followed, clinging to its edge. At midsummer upon Mars it was
described as a barely discernible thread drawn round the minute
white patch, which was all that then remained of the enormous
snow-fields of some months before. Finally, when the cap vanished,
the spot, where its girdle, long since too small for detection, had
existed, had become one yellow stretch.1 That the belt seen upon
this occasion was water, or at any rate liquid formed by the
melting of the polar cap, appears a plausible s...
