It was after this army had been lost in the black shadows of the forest floor, that I remembered those others who had come with them--those attendant birds of prey who profit by the evil work of this legion. For, hovering over them, sometimes a little in advance, there had been a flying squadron of antbirds and others which had come to feed, not on the ants, but on the insects which had been frightened into flight. At one time, three of these dropped down to perch on my hammock, nervous, watchful, and alert, waiting but a moment before darting after some ill-fated moth or grasshopper which, in its great panic, had escaped one danger only to fall an easy victim to another. For a little while, the twittering and chirping of these camp-followers, these feathered profiteers, was brought back to me on the wind; and when it had died away, I took up my work again in a glade in which no voice of insect reached my ears. The hunting ants had done their work thoroughly. And so it comes about that by day or by night the hammock carries with it its own reward to those who have learned but one thing--that there is a chasm between pancakes and truffles. It is an open door to a new land which does not fail of its promise, a land in which the prosaic, the ordinary, the everyday have no place, since they have been shouldered out, dethroned, by a new and competent perspective. The god of hammocks is unfailingly kind, just, and generous to those who have found pancakes wanting and have discovered by inspiration, or what-not, that truffles do not grow in back-yards to be served at early breakfast by the maid-of-all-work. Which proves, I believe, that a mere bed may be a block in the path of philosophy, a commonplace, and that truffles and hammocks--hammocks unquestionably--are twin doors to the land of romance. The swayer in hammocks may find amusement and may enrich science by his record of observations; his memory will be more vivid, his caste the worthier, for the intimacy with wild things achieved when swinging between earth and sky, unfettered by mattress or roof. X A TROPIC GARDEN Take an automobile and into it pile a superman, a great evolutionist, an artist, an ornithologist, a poet, a botanist, a photographer, a musician, an author, adorable youngsters of fifteen, and a tired business man, and within half an hour I shall have drawn from them superlatives of appreciation, each after his own method of emotional expression--whether a flood of exclamations, or silence. This is no light boast, for at one time or another, I have done all this, but in only one place--the Botanical Gardens of Georgetown, British Guiana. As I hold it sacrilege to think of dying without again seeing the Taj Mahal, or the Hills from Darjeeling, so something of ethics seems involved in my soul's necessity of again watching the homing of the herons in these tropic gardens at evening.
