Whether I had spent the day in hard tramping or stalking in the jungle, or at my laboratory table trying to disentangle the whys and wherefores from the physical skein of my specimens, toward sunset I always went down to the cement floor of an orchid-house long fallen in decay. This was under the open sky, and from this spot on the highest hilltop in all this region, I watched the end of the day. No sunset should ever be described, and the Kalacoon sunsets were too wonderful for aught but wordless reverence. They were explosions of wild glory, palettefuls of unheard-of pigments splashed across the sky, and most bewildering because they were chiefly in the east or north. This evening on which I write was sealed with a sunset of negligible yellow, but the east was a splendor of forest fires and minarets, great golden castles and pale-green dragons and snow-capped mountains all conceived and molded from glorious tumbled cloud-masses, and ultimately melting back into them again. The moriche orioles met the beauty of the heavens with their silver notes, and as the sky cooled, there arose the sweet, trilled cadence of the little tinamou heralding the voices of night. The silvery collared nighthawks began their eternal questioning _who-are-you! who-are-you!_ and the coolness banished all thought of the blistering sunshine now pouring down upon the waters of the Pacific. Not until later, when the night-life was fairly under way, and all the beings of the sun hidden and asleep, did the deep bass rumble of the big toads commence, and the tinkling chorus of the little frogs. Last of all came the essence of the nocturnal--the sound furthest removed from day. All other voices seemed to become for an instant hushed, and the poor-me-one spoke--a wail which rose, trembled, and broke into a falling cadence of hopeless sighs. And now, with the crescent moon writing its heliograph cipher upon the water, a new sound arose, low and indistinct, lost for a moment, then rising and lost again. Then it rang out rich and harmonious, the full-throated paddling chanty of a gold-boat of blacks coming down river with their tiny pokes of glittering dust. It tore at the heart-strings of memory, and in its wildness, its sad minor strain, was strangely moving. The steersman set the words and in high, quavering tones led the chorus, which broke in, took up the phrase, different each time, and repeated it twice over, with a sweet pathos, a finality of cadence which no trained white chorus could reproduce.
