Proof against the poison gas, the hideous monsters were, and invulnerable to shot and shell. Divided and sub-divided, slashed into ribbons, blown to fragments by bombs, each of the pieces simply became the nucleus of a new organism, able, within a few hours, to assume the outlines of a dwarf man, and to seize and devour its prey. But the Argentine expedition had done worse than it at first dreamed of. _It had given the monsters a taste for human flesh!_ After that, the wave of devastation had obliterated life in every city clear up to the Amazonian forests. And then it had been discovered that, by feeding these devils human flesh, they could be rendered torpid and their advance stayed--so long as the periodical meals continued! At first criminals had been supplied them, then natives, then Chinese, obtained by periodical war raids. What would you have? The savage regions of the earth had already been depopulated, and a frenzy of fear had taken possession of the whole world. Now the Chinese had defeated the annual American invasion, and the Earth Giants were budding and swarming through the heart of Brazil. * * * * * "Man," said the Theosophists, "is the fifth of the great root-races that have inhabited this planet. The fourth were the Atlanteans. The third were the Lemurians, half-human beings of whom the Australian aborigines are the survivors. The second race was not fully organized into human form. Of the first, nothing is known. "These are the second race, surviving in the Antarctic valleys. Half-human objects, groping toward that perfection of humanity of which we ourselves fall very far short. As the Kabbala says, man, before Adam, reached from heaven to earth." Kay Bevan and Cliff Hynes had been working feverishly to perfect their Crumbler for use in the Chinese wars. Convinced, as were all fair-minded men, that these annual raids were unjustified, they yielded to the logic of the facts. Should America sacrifice a hundred thousand of her boys and girls each year, when human life was cheap in China? _Boys and girls!_ It had been discovered that the Earth Giants required the flesh of women as well as of men. Some subtle chemical constituent then produced the state of torpidity during which the advance and the budding of the monsters was stayed. During the ten past years their northward advance had been almost inappreciable. Brazil had even sent another army against them. But the deadliest gases had failed to destroy the tenacious life of these protoplasmic creatures, and the tanks, which had driven through and through them, had become entangled and blocked in the gelatinous exudations, and their occupants eaten.
