And as though it had been foreseen, and a policy arranged to meet it, the white army no longer fought in the open, but lined up along the walls to defend the immovable caves. They avoided the working jaws of the other kind, which certainly needed no garrison, and drifting slowly in the eddies, fought as they could, with decreasing strength and increasing death-rate. And thus it happened that our conservative non-combatant, out in midstream, found himself surrounded by a horde of black enemies who had nothing better to do than attack him.
And they did. As many as could crowd about him closed their wicked jaws in his flesh. Squirming with pain, rendered trebly strong by his terror, he killed them by twos and threes as he could reach them with his tail. He shook them off with nervous contortions, only to make room for more. He plunged, rolled, launched himself forward and back, up and down, out and in, bending himself nearly double, then with lightning rapidity throwing himself far into the reverse curve. He was fighting for his life, and knew it. When he could, he used his jaws, only once to an enemy. He saw dimly at intervals that the white monsters were watching him; but none offered to help, and he had not time to call.
He thought that he must have become the object of the war; for from all sides they swarmed, crowding about him, seeking a place on which to fasten their jaws. Little by little the large red-and-gray creatures, the non-combatants, and the phosphorescent animals were pushed aside, and he, the center of an almost solid black mass, fought, in utter darkness, with the fury of extreme fright. He had no appreciation of the passing of time, no knowledge of his distance from the wall, or the destination of this never-pausing current. But finally, after an apparently interminable period, he heard dimly, with failing consciousness, the reverberations of the thunder, and knew momentary respite as the violent cross-currents tore his assailants away. Then, still in darkness, he felt the crashing and tearing of flesh against obstructing walls and sharp corners, the repetition of thunder and the roar of the current which told him he was once more in a large tunnel. An instant of light from a venturesome torch showed him to his enemies, and again he fought, like a whale in his last flurry, slowly dying from exhaustion and pain, but still potential to kill—terrible in his agony. There was no counting of scalps in that day's work; but perhaps no devouring white monster in all the defensive army could have shown a death-list equal to this. From the surging black cloud there was a steady outflow of the dead, pushed back by the living.
Weaker and weaker, while they mangled his flesh, and still in darkness, he fought them down through branching passages to another network of small tunnels, where he caught a momentary view of the walls and the stolid white guard, thence on to what he knew was open space. And here he felt that he could fight no more. They had covered him completely, and, try as he might with his failing strength, he could not dislodge them. So he ceased his struggles; and numb with pain, dazed with despair, he awaited the end.
But it did not come. He was too exhausted to feel surprise or joy when they suddenly dropped away from him; but the instinct of self-preservation was still in force, and he swam toward the wall. The small creatures paid him no attention; they scurried this way and that, busy with troubles of their own, while he crept stupidly and painfully between two white sentries floating in the eddies,—one of whom considerately made room for him,—and anchored to a projection, luckily choosing a harbor that was not hostile.
"Any port in a storm, eh, neighbor?" said the one who had given him room, and who seemed to notice his dazed condition. "You'll feel better soon. My, but you put up a good fight, that's what you did!"
He could not answer, and the friendly guard resumed his vigil. In a few moments, however, he could take cognizance of what was going on in the stream. There was a new army in the fight, and reinforcements were still coming. A short distance above him was a huge rent in the wall, and the caves around it, crushed and distorted, were grinding fiercely. Protruding through the rent and extending half-way across the tunnel was a huge mass of some strange substance, roughly shaped to a cylindrical form. It was hollow, and out of it, by thousands and hundred thousands, was pouring the auxiliary army, from which the black fighters were now fleeing for dear life.
The newcomers, though resembling in general form the creatures they pursued, were much larger and of two distinct types. Both were light brown in color; but while one showed huge development of head and jaw, with small flippers, the other kind reversed these attributes, their heads being small, but their flippers long and powerful. They ran their quarry down in the open, and seized them with outreaching tentacles. No mistakes were made—no feints or false motions; and there was no resistance by the victims. Where one was noticed he was doomed. The tentacles gathered him in—to a murderous bite or a murderous embrace.
At last, when the inflow had ceased,—when there must have been millions of the brown killers in the tunnel,—the great hollow cylinder turned slowly on its axis and backed out through the rent in the wall, which immediately closed, with a crushing and scattering of fragments. Though the allies were far down-stream now, the war was practically ended; for the white defenders remained near the walls, and the black invaders were in wildest panic, each one, as the resistless current rushed him past, swimming against the stream, to put distance between himself and the destroyer below. But before long an advance-guard of the brown enemy shot out from the tributaries above, and the tide of retreat swung backward. Then came thousands of them, and the massacre was resumed.
"Hot stuff, eh?" said his friendly neighbor to him.
