this world is still crowded with life, but crowded only with what they
regard as inferior animals. To carry warfare sunward is, indeed,
their only escape from the destruction that, generation after
generation, creeps upon them.

And before we judge of them too harshly we must remember what
ruthless and utter destruction our own species has wrought, not only
upon animals, such as the vanished bison and the dodo, but upon its
inferior races. The Tasmanians, in spite of their human likeness,
were entirely swept out of existence in a war of extermination waged
by European immigrants, in the space of fifty years. Are we such
apostles of mercy as to complain if the Martians warred in the same
spirit?

The Martians seem to have calculated their descent with amazing
subtlety--their mathematical learning is evidently far in excess of
ours--and to have carried out their preparations with a well-nigh
perfect unanimity. Had our instruments permitted it, we might have
seen the gathering trouble far back in the nineteenth century. Men
like Schiaparelli watched the red planet--it is odd, by-the-bye, that
for countless centuries Mars has been the star of war--but failed to
interpret the fluctuating appearances of the markings they mapped so
well. All that time the Martians must have been getting ready.

During the opposition of 1894 a great light was seen on the
illuminated part of the disk, first at the Lick Observatory, then by
Perrotin of Nice, and then by other observers. English readers heard
of it first in the issue of _Nature_ dated August 2. I am inclined to
think that this blaze may have been the casting of the huge gun, in
the vast pit sunk into their planet, from which their shots were fired
at us. Peculiar markings, as yet unexplained, were seen near the site
of that outbreak during the next two oppositions.

The storm burst upon us six years ago now. As Mars approached
opposition, Lavelle of Java set the wires of the astronomical exchange
palpitating with the amazing intelligence of a huge outbreak of
incandescent gas upon the planet. It had occurred towards midnight of
the twelfth; and the spectroscope, to which he had at once resorted,
indicated a mass of flaming gas, chiefly hydrogen, moving with an
enormous velocity towards this earth. This jet of fire had become
invisible about a quarter past twelve. He compared it to a colossal
puff of flame suddenly and violently squirted out of th
