Guided by this, I might enter into a new field of naturalizing and say to those who might, in excitement, be tempted to do otherwise, "Look at your traps before lifting them." But my audience would be too limited; I will refrain from so doing.
It is true that this brief experience might be looked upon as one illustration of the perils of the wilderness, since it is not customary for the fer-de-lance to frequent the city and the town. But this would give rise to a footless argument, leading nowhere. For danger is everywhere—it lurks in every shadow and is hidden in the bright sunlight, it is the uninvited guest, the invisible pedestrian who walks beside you in the crowded street ceaselessly, without tiring. But even a fer-de-lance should rather add to the number of hammock devotees than diminish them; for the three feet or more of elevation is as good as so many miles between the two of you. And three miles from any serpent is sufficient.
It may be that the very word danger is subjected to a different interpretation in each one of our mental dictionaries. It is elastic, comprehensive. To some it may include whatever is terrible, terrifying; to others it may symbolize a worthy antagonist, one who throws down the gauntlet and asks no questions, but who will make a good and fair fight wherein advantage is neither taken nor given. I suppose, to be bitten by vampires would be thought a danger by many who have not graduated from the mattress of civilization to this cubiculum of the wilderness. This is due, in part, to an ignorance, which is to be condoned; and this ignorance, in turn, is due to that lack of desire for a knowledge of new countries and new experiences, which lack is to be deplored and openly mourned. Many years ago, in Mexico, when I first entered the vampire zone, I was apprised of the fact by the clotted blood on my horse's neck in the early morning. In actually seeing this evidence, I experienced the diverse emotions of the discoverer, although as a matter of fact I had discovered nothing more than the verification of a scientific commonplace. It so happened that I had read, at one time, many conflicting statements of the workings of this aerial leech; therefore, finding myself in his native habitat, I went to all sorts of trouble to become a victim to his sorceries. The great toe is the favorite and stereotyped point of attack, we are told; so, in my hammock, my great toes were conscientiously exposed night after night, but not until a decade later was my curiosity satisfied.
I presume that this was a matter of ill luck, rather than a personal matter between the vampire and me. Therefore, as a direct result of this and like experiences, I have learned to make proper allowances for the whims of the Fates. I have learned that it is their pleasure to deluge me with rainstorms at unpropitious moments, also to send me, with my hammock, to eminently desirable countries, which, however, are barren of trees and scourged of every respectable shrub. That the showers may not find me unprepared, I pack with my hamaca an extra length of rope, to be stretched taut from foot-post to head-post, that a tarpaulin or canvas may be slung over it. When a treeless country is presented to me in prospect, I have two stout stakes prepared, and I do not move forward without them.
It is a wonderful thing to see an experienced hammocker take his stakes, first one, then the other, and plunge them into the ground three or four times, measuring at one glance the exact distance and angle, and securing magically that mysterious "give" so essential to well-being and comfort. Any one can sink them like fence-posts, so that they stand deep and rigid, a reproach and an accusation; but it requires a particular skill to judge by the pull whether or not they will hold through the night and at the same time yield with gentle and supple swing to the least movement of the sleeper. A Carib knows, instantly, worthy and unworthy ground. I have seen an Indian sink his hamaca posts into sand with one swift, concentrated motion, mathematical in its precision and surety, so that he might enter at once into a peaceful night of tranquil and unbroken slumber, while I, a tenderfoot then, must needs beat my stakes down into the ground with tremendous energy, only to come to earth with a resounding thwack the moment I mounted my couch.
The Red Man made his comment, smiling: "Yellow earth, much squeeze." Which, being translated, informed me that the clayey ground I had chosen, hard though it seemed, was more like putty in that it would slip and slip with the prolonged pressure until the post fell inward and catastrophe crowned my endeavor.
So it follows that the hammock, in company with an adequate tarpaulin and two trustworthy stakes, will survive the heaviest downpour as well as the most arid and uncompromising desert. But since it is man-made, with finite limitations, nature is not without means to defeat its purpose. The hammock cannot cope with the cold—real cold, that is, not the sudden chill of tropical night which a blanket resists, but the cold of the north or of high altitudes. This is the realm of the sleeping-bag, the joy of which is another story. More than once I have had to use a hammock at high levels, since there was nothing else at hand; and the numbness of the Arctic was mine. Every mesh seemed to invite a separate draught. The winds of heaven—all four—played unceasingly upon me, and I became in due time a swaying mummy of ice. It was my delusion that I was a dead Indian cached aloft upon my arboreal bier—which is not a normal state of mind for the sleeping explorer.
Anything rather than this helpless surrender to the elements. Better the lowlands and that fantastic shroud, the mosquitaro. For even to wind one's self into this is an experience of note. It is ingenious, and called the mosquito shirt because of its general shape, which is as much like a shirt as anything else. A large round center covers the hammock, and two sleeves extend up the supporting strands and inclose the ends, being tied to the ring-ropes. If at sundown swarms of mosquitoes become unbearable, one retires into his netting funnel, and there disrobes. Clothes are rolled into a bundle and tied to the hammock, that one may close one's eyes reasonably confident that the supply will not be diminished by some small marauder. It is then that a miracle is enacted. For one is at last enabled, under these propitious circumstances, to achieve the impossible, to control and manipulate the void and the invisible, to obey that unforgotten advice of one's youth, "Oh, g'wan—crawl into a hole and pull the hole in after you!" At an early age, this unnatural advice held my mind, so that I devised innumerable means of verifying it; I was filled with a despair and longing whenever I met it anew. But it was an ambition appeased only in maturity. And this is the miracle of the tropics: climb up into the hamaca, and, at this altitude, draw in the hole of the mosquitaro funnel, making it fast with a single knot. It is done. One is at rest, and lying back, listens to the humming of all the mosquitoes in the world, to be lulled to sleep by the sad, minor singing of their myriad wings. But though I have slung my hammock in many lands, on all the continents, I have few memories of netting nights. Usually, both in tropics and in tempered climes, one may boldly lie with face uncovered to the night.
And this brings us to the greatest joy of hammock life, admission to the secrets of the wilderness, initiation to new intimacies and subtleties of this kingdom, at once welcomed and delicately ignored as any honored guest should be. For this one must make unwonted demands upon one's nocturnal senses. From habit, perhaps, it is natural to lie with the eyes wide open, but with all the faculties concentrated on the two senses which bring impressions from the world of darkness—hearing and smell. In a jungle hut a loud cry from out of the black treetops now and then reaches the ear; in a tent the faint noises of the night outside are borne on the wind, and at times the silhouette of a passing animal moves slowly across the heavy cloth; but in a hamaca one is not thus set apart to be baffled by hidden mysteries—one is given the very point of view of the creatures who live and die in the open.
Through the meshes which press gently against one's face comes every sound which our human ears can distinguish and set apart from the silence—a silence which in itself is only a mirage of apparent soundlessness, a testimonial to the imperfection of our senses. The moaning and whining of some distant beast of prey is brought on the breeze to mingle with the silken swishing of the palm fronds overhead and the insistent chirping of many insects—a chirping so fine and shrill that it verges upon the very limits of our hearing. And these, combined, unified, are no more than the ground surge beneath the countless waves of sound. For the voice of the jungle is the voice of love, of hatred, of hope, of despair—and in the night-time, when the dominance of sense-activity shifts from eye to ear, from retina to nostril, it cries aloud its confidences to all the world. But the human mind is not equal to a true understanding of these; for in a tropical jungle the birds and the frogs, the beasts and the insects are sending out their messages so swiftly one upon the other, that the senses fail of their mission and only chaos and a great confusion are carried to the brain. The whirring of invisible wings and the movement of the wind in the low branches become one and the same: it is an epic, told in some strange tongue, an epic filled to overflowing with tragedy, with poetry and mystery. The cloth of this drama is woven from many-colored threads, for Nature is lavish with her pigment, reckless with life and death. She is generous because there is no need for her to be miserly. And in the darkness, I have heard the working of her will, translating as best I could.
