But the scent of the giant armadillo eluded us. When we waded through some new, strange odor I looked back at Nupee, hoping for some sign that it was the one we sought. But that night the great armored creatures went their way and we ours, and the two did not cross. Nupee showed me a track at the trail-side made long ago, as wide and deep as the spoor of a dinosaur, and I fingered it reverently as I would have touched the imprint of a recently alighted pterodactyl, taking care not to spoil the outlines of the huge claw-marks. All my search for him had been in vain thus far, though I had been so close upon his trail as to have seen fresh blood. I had made up my mind not to give up, but it seemed as if success must wait for another year. We watched and called the ghostly kinkajous and held them fascinated with our stream of light; we roused unnamable creatures which squawked companionably at us and rustled the tree-top leaves; we listened to the whispered rush of passing vampires skimming our faces and were soothed by the hypnotic droning hum which beetles left in their swift wake. Finally we turned and circled through side trails so narrow and so dark that we walked with outstretched arms, feeling for the trunks and lianas, choosing a sloth's gait and the hope of new adventures rather than the glare of my flash on our path. When we entered the Convict Trail, we headed toward home. Within sight of the first turn a great black limb of a tree had recently fallen across the trail in a patch of moonlight. Before we reached it, the branch had done something it should not have done--it had straightened slightly. We strained our eyes to the utmost but could not, in this eerie light, tell head from tail end of this great serpent. It moved very slowly, and with a motion which perfectly confounded our perception. Its progress seemed no faster than the hour hand of a watch, but we knew that it moved, yet so close to the white sand that the whole trail seemed to move with it. The eye refused to admit any motion except in sudden shifts, like widely separated films of a motion-picture. For minute after minute it seemed quiescent; then we would blink and realize that it was two feet higher up the bank. One thing we could see--a great thickening near the center of the snake: it had fed recently and to repletion, and slowly it was making its way to some hidden lair, perhaps to lie motionless until another moon should silver the jungle. Was there any stranger life in the world?
