Twice, deeper in the jungle, we squatted and listened, and twice the silence remained unbroken and the air unmoved. Happening to look up through a lofty, narrow canyon of dark foliage, I was startled as by some sudden sound by seeing a pure white cloud, moonlit, low down, pass rapidly across. It was first astounding, then unreal: a bit of exceedingly poor work on the part of the property man, who had mixed the hurricane scenery with that of the dog-days. Even the elements seemed to have been laved with magic. The zone of high wind, with its swift-flying clouds, must have been flowing like a river just above the motionless foliage of the tree-tops. This piece of ultra-unnaturalism seemed to break part of the spell and the magic silence was lifted. Two frogs boomed again, close at hand, and now all the hound similitude was gone, and in its place another, still more strange, when we think of the goggle-eyed author far up in the trees. The sound now was identical with the short cough or growl of a hungry lion, and though I have heard the frogs many times since that night, this resemblance never changed or weakened. It seemed as if the volume, the roaring outburst, could come only from the throat of some large, full-lunged mammal. A sudden tearing rush from the trail-side, and ripping of vines and shrubs, was mingled with deep, hoarse snorts, and we knew that we had disturbed one of the big red deer--big only in comparison with the common tiny brown brockets. A few yards farther the leaves rustled high overhead, although no breath of wind had as yet touched the jungle. I began a slow, careful search with my flashlight, and, mingled with the splotches and specks of moonlight high overhead, I seemed to see scores of little eyes peering down. But at last my faint electric beam found its mark and evolved the first bit of real color which the jungle had shown--always excepting the ruby tail-light. Two tiny red globes gleamed down at us, and as they gleamed, moved without a sound, apparently unattached, slowly through the foliage. Then came a voice, as wandering, as impersonal as the eyes--a sharp, incisive _wheeeeeat!_ with a cat-like timbre; and from the eyes and voice I reconstructed a night monkey--a kinkajou. Then another notch was slipped and the jungle for a time showed something of the exuberance of its life. A paca leaped from its meal of nuts and bounced away with quick, repeated pats; a beetle with wings tuned to the bass clef droned by; some giant tree-cricket tore the remaining intervals of silence to shreds with unmuted wing-fiddles, _cricks_ so shrill and high that they well-nigh passed beyond the upper register of my ear out into silence again. The roar of another frog was comforting to my ear-drum.
