hich the systems of these creatures
differed from ours was in what one might have thought a very trivial
particular. Micro-organisms, which cause so much disease and pain on
earth, have either never appeared upon Mars or Martian sanitary
science eliminated them ages ago. A hundred diseases, all the fevers
and contagions of human life, consumption, cancers, tumours and such
morbidities, never enter the scheme of their life. And speaking of
the differences between the life on Mars and terrestrial life, I may
allude here to the curious suggestions of the red weed.

Apparently the vegetable kingdom in Mars, instead of having green
for a dominant colour, is of a vivid blood-red tint. At any rate, the
seeds which the Martians (intentionally or accidentally) brought with
them gave rise in all cases to red-coloured growths. Only that known
popularly as the red weed, however, gained any footing in competition
with terrestrial forms. The red creeper was quite a transitory
growth, and few people have seen it growing. For a time, however, the
red weed grew with astonishing vigour and luxuriance. It spread up
the sides of the pit by the third or fourth day of our imprisonment,
and its cactus-like branches formed a carmine fringe to the edges of
our triangular window. And afterwards I found it broadcast throughout
the country, and especially wherever there was a stream of water.

The Martians had what appears to have been an auditory organ, a
single round drum at the back of the head-body, and eyes with a visual
range not very different from ours except that, according to Philips,
blue and violet were as black to them. It is commonly supposed that
they communicated by sounds and tentacular gesticulations; this is
asserted, for instance, in the able but hastily compiled pamphlet
(written evidently by someone not an eye-witness of Martian actions)
to which I have already alluded, and which, so far, has been the chief
source of information concerning them. Now no surviving human being
saw so much of the Martians in action as I did. I take no credit to
myself for an accident, but the fact is so. And I assert that I
watched them closely time after time, and that I have seen four, five,
and (once) six of them sluggishly performing the most elaborately
complicated operations together without either sound or gesture. Their
peculiar hooting invariably preceded feeding; it had no modulation,
and was, I believe, in no sense a sig
