It was nearly midnight. We traversed a broad trail of white sand, between lines of saplings of pale-barked rubber trees, flooded, saturated, with milky-gray light. Not a star appeared in the cloudless sky, which, in contrast to the great silver moon-plaque, was blue-black. These open sandy stretches, so recently etched into what had been primitive jungle, were too glowing with light for most of the nocturnal creatures who, in darkness, flew and ran and hunted about in them. And the lovers of twilight were already come and gone. The stage was vacant save for one actor--the nighthawk of the silvery collar, whose eerie _wheeeo!_ or more leisurely and articulate _who-are-you?_ was queried from stump and log. There was in it the same liquid tang, the virile ringing of skates on ice, which enriches the cry of the whip-poor-will in our country lanes. Where the open trail skirted a hillside we came suddenly upon a great gathering of these goatsuckers, engaged in some strange midnight revel. Usually they roost and hunt and call in solitude, but here at least forty were collected on the white sand within an area of a few yards. We stopped and watched. They were dancing--or, rather, popping, as corn pops in a hopper. One after another, or a half dozen at a time, they bounced up a foot or two from the ground and flopped back, at the instant of leaving and returning uttering a sudden, explosive _wop!_ This they kept up unceasingly for the five minutes we gave to them, and our passage interrupted them for only a moment. Later we passed single birds which popped and wopped in solitary state; whether practicing, or snobbishly refusing to perform in public, only they could tell. It was a scene not soon forgotten. Suddenly before us rose the jungle, raw-edged, with border zone of bleached, ashamed trunks and lofty branches white as chalk, of dead and dying trees. For no jungle tree, however hardy, can withstand the blasting of violent sun after the veiling of emerald foliage is torn away. As the diver plunges beneath the waves, so, after one glance backward over the silvered landscape, I passed at a single stride into what seemed by contrast inky blackness, relieved by the trail ahead, which showed as does a ray of light through closed eyelids. As the chirruping rails climbed among the roots of the tall cat-tails out yonder, so we now crept far beneath the level of the moonlit foliage. The silvery landscape had been shifted one hundred, two hundred feet above the earth. We had become lords of creation in name alone, threading our way humbly among the fungi and toadstools, able only to look aloft and wonder what it was like. And for a long time no voice answered to tell us whether any creature lived and moved in the tree-tops.
