hen the octopi struck with another weapon, in an effort to dull the spearing beams of white. Here and there from the mass of black an even blacker cloud began to emerge. It quickly settled over the whole scene, pervading it with a pitchy, clinging darkness that obscured each man from his neighbor.
"Ink!" cried one of them. It was sepia from the cuttlefish's ink sacs—the weapon with which these monsters of the underseas blind and confuse their victims.
"Faster!" the commander roared in answer. "And for heaven's sake, keep together!"
They huddled closer. Under the protecting cloud of ink the mass of octopi pressed nearer. The struggle became fantastic, unreal, as the brilliant beams of white bored through the utter blackness searching for eyes which the men knew were there, yet could not see until their rays chanced upon them. Snaky shadows milled horribly close to the little group of bulging yellow figures. Blacker and blacker grew the water; they could not always see the monsters as they drove them back on each side. Now and then a bold tentacle actually touched one of them for a moment before its owner was thrust, blinded, away.
Suddenly the dark cloud cleared a little as the fight moved into an unseen current. Their range of vision lengthened to ten or twelve feet; they could dimly sense the looming mass of cuttlefish: and it was less often that one of the monsters darted forward, daring the rays of white, and became altogether visible. When this did happen, half a dozen dazzling beams converged on the octopus' eyes and drove it back in writhing agony.
The men were the hub of a grotesque cartwheel, whose spokes were inter-crossing rays of white. They still forged onward along the groove, but moved more slowly now, and Keith Wells, tired to death, realized the combat could not go on much longer. Their advance was useless; a mere jest. The NX-1 had vanished. It would only be a question of time before their batteries gave out, or the swarms of octopi crushed in on the struggling crew. Their overwhelming numbers would tell in the end.... The men were silent, except for the occasional gasps which came from their laboring lungs.
