Stanley was the first of us to recover from the shock of this spectacle. He faced about and raised his voice in shouts of warning to the resting Zyobites. For other glass encased monsters had appeared beside the first, now.
One by one, in single file like a line of enormous marching insects, they crawled down the wall and humped along on their tentacles--around the ditch and toward us!
The deadly infallibility of that second attack!
The Quabos advanced on us like armored tanks bearing down on defenceless savages. Their glass helmets, in addition to containing water for their breathing, protected them from our knives and axes. We were utterly helpless against them.
They marched in ranks about twenty yards apart, each rank helping the one in front to carry the cumbersome water-hoses which trailed back to the central water supply in the tunnel.
Their movements were slow, weighted down as they were by the great glass helmets, but they were appallingly sure.
We could not even retard their advance, let alone stop it. Here were no suffocating, faltering creatures. Here were beings possessed of their full vigor, each one equal to three of us even as the Professor had conjectured. Their only weak points were their tentacles which trailed outside the glass cases. But these they kept coiled close, so that to reach them and hack at them we had to step within range of their terrific clutches.
The Zyobites fought with the valor of despair added to their inherent noble bravery. Man after man closed with the monstrous, armored Things--only to be seized and crushed by the weaving tentacles.
Occasionally a terrific blow with an ax would crack one of the glass helmets. Then the denuded Quabo would flounder convulsively in the air till it drowned. But there were all too few of these individual victories. The main body of the Quabos, rank on rank, dragging their water-hose behind them, came on with the steadiness of a machine.
Slowly we were driven back down the broad street and toward the palace. As we retreated, old people and children came from the houses and went with us, leaving their dwellings to the mercy of the monsters.
A block from the palace we bunched together and, by sheer mass and ferocity, actually stopped the machinelike advance for a few moments. Miscellaneous weapons had been brought from the houses--sledges, stone benches, anything that might break the Quabos' helmets--and handed to us in silence by the noncombatants.
