Their slow reptilian natures cared nothing for wounds, and the springs of their lives, with no special brain center but scattered throughout their spinal cords, could not be tapped by any modern weapons. The most that we could do was to check their progress by distracting their attention with the flash and roar of our guns, and so to give both the natives and ourselves time to reach the steps which led to safety. But where the conical explosive bullets of the twentieth century were of no avail, the poisoned arrows of the natives, dipped in the juice of strophanthus and steeped afterwards in decayed carrion, could succeed. Such arrows were of little avail to the hunter who attacked the beast, because their action in that torpid circulation was slow, and before its powers failed it could certainly overtake and slay its assailant. But now, as the two monsters hounded us to the very foot of the stairs, a drift of darts came whistling from every chink in the cliff above them. In a minute they were feathered with them, and yet with no sign of pain they clawed and slobbered with impotent rage at the steps which would lead them to their victims, mounting clumsily up for a few yards and then sliding down again to the ground. But at last the poison worked. One of them gave a deep rumbling groan and dropped his huge squat head on to the earth. The other bounded round in an eccentric circle with shrill, wailing cries, and then lying down writhed in agony for some minutes before it also stiffened and lay still. With yells of triumph the Indians came flocking down from their caves and danced a frenzied dance of victory round the dead bodies, in mad joy that two more of the most dangerous of all their enemies had been slain. That night they cut up and removed the bodies, not to eat--for the poison was still active--but lest they should breed a pestilence. The great reptilian hearts, however, each as large as a cushion, still lay there, beating slowly and steadily, with a gentle rise and fall, in horrible independent life. It was only upon the third day that the ganglia ran down and the dreadful things were still.
Some day, when I have a better desk than a meat-tin and more helpful tools than a worn stub of pencil and a last, tattered note-book, I will write some fuller account of the Accala Indians--of our life amongst them, and of the glimpses which we had of the strange conditions of wondrous Maple White Land. Memory, at least, will never fail me, for so long as the breath of life is in me, every hour and every action of that period will stand out as hard and clear as do the first strange happenings of our childhood. No new impressions could efface those which are so deeply cut. When the time comes I will describe that wondrous moonlit night upon the great lake when a young ichthyosaurus--a strange creature, half seal, half fish, to look at, with bone-covered eyes on each side of his snout, and a third eye fixed upon the top of his head--was entangled in an Indian net, and nearly upset our canoe before we towed it ashore; the same night that a green water-snake shot out from the rushes and carried off in its coils the steersman of Challenger's canoe. I will tell, too, of the great nocturnal white thing--to this day we do not know whether it was beast or reptile--which lived in a vile swamp to the east of the lake, and flitted about with a faint phosphorescent glimmer in the darkness. The Indians were so terrified at it that they would not go near the place, and, though we twice made expeditions and saw it each time, we could not make our way through the deep marsh in which it lived. I can only say that it seemed to be larger than a cow and had the strangest musky odor. I will tell also of the huge bird which chased Challenger to the shelter of the rocks one day--a great running bird, far taller than an ostrich, with a vulture-like neck and cruel head which made it a walking death. As Challenger climbed to safety one dart of that savage curving beak shore off the heel of his boot as if it had been cut with a chisel.
