But one does not drop off to sleep in this before a just and proper preparation. This presents complexities. First, the hammock must be slung with just the right amount of tautness; then, the novice must master the knack of winding himself in his blanket that he may slide gently into his aerial bed and rest at right angles to the tied ends, thus permitting the free side-meshes to curl up naturally over his feet and head. This cannot be taught. It is an art; and any art is one-tenth technique, and nine-tenths natural talent. However, it is possible to acquire a certain virtuosity, which, after all is said, is but pure mechanical skill as opposed to sheer genius. One might, perhaps, get a hint by watching the living chrysalid of a potential moon-moth wriggle back into its cocoon—but little is to be learned from human teaching. However, if, night after night, one observes his Indians, a certain instinctive knowledge will arise to aid and abet him in his task. Then, after his patient apprenticeship, he may reap as he has sowed. If it is to be disaster, it is as immediate as it is ignominious; but if success is to be his portion, then he is destined to rest, wholly relaxed, upon a couch encushioned and resilient beyond belief. He finds himself exalted and supreme above all mundane disturbances, with the treetops and the stars for his canopy, and the earth a shadowy floor far beneath. This gentle aerial support is distributed throughout hundreds of fine meshes, and the sole contact with the earth is through twin living boles, pulsing with swift running sap, whose lichened bark and moonlit foliage excel any tapestry of man's devising.

Perhaps it is atavistic—this desire to rest and swing in a hamaca. For these are not unlike the treetop couches of our arboreal ancestors, such a one as I have seen an orang-utan weave in a few minutes in the swaying crotch of a tree. At any rate, the hammock is not dependent upon four walls, upon rooms and houses, and it partakes altogether of the wilderness. Its movement is æolian—yielding to every breath of air. It has even its own weird harmony—for I have often heard a low, whistling hum as the air rushed through the cordage mesh. In a sudden tropical gale every taut strand of my hamaca has seemed a separate, melodious, orchestral note, while I was buffeted to and fro, marking time to some rhythmic and reckless tune of the wind playing fortissimo on the woven strings about me. The climax of this musical outburst was not without a mild element of danger—sufficient to create that enviable state of mind wherein the sense of security and the knowledge that a minor catastrophe may perhaps be brought about are weighed one against the other.

Special, unexpected, and interesting minor dangers are also the province of the hamaca. Once, in the tropics, a great fruit fell on the elastic strands and bounced upon my body. There was an ominous swish of the air in the sweeping arc which this missile described, also a goodly shower of leaves; and since the fusillade took place at midnight, it was, all in all, a somewhat alarming visitation. However, there were no honorable scars to mark its advent; and what is more important, from all my hundreds of hammock nights, I have no other memory of any actual or threatened danger which was not due to human carelessness or stupidity. It is true that once, in another continent, by the light of a campfire, I saw the long, liana-like body of a harmless tree-snake wind down from one of my fronded bed-posts and, like a living woof following its shuttle, weave a passing pattern of emerald through the pale meshes. But this heralded no harm, for the poisonous reptiles of that region never climb; and so, since I was worn out by a hard day, I shut my eyes and slept neither better nor worse because of the transient confidence of a neighborly serpent.

As a matter of fact, the wilderness provides but few real perils, and in a hammock one is safely removed from these. One lies in a stratum above all damp and chill of the ground, beyond the reach of crawling tick and looping leech; and with an enveloping mosquitaro, or mosquito shirt, as the Venezuelans call it, one is fortified even in the worst haunts of these most disturbing of all pests.

Once my ring rope slipped and the hammock settled, but not enough to wake me up and force me to set it to rights. I was aware that something had gone wrong, but, half asleep, I preferred to leave the matter in the lap of the gods. Later, as a result, I was awakened several times by the patting of tiny paws against my body, as small jungle-folk, standing on their hind-legs, essayed to solve the mystery of the swaying, silent, bulging affair directly overhead. I was unlike any tree or branch or liana which had come their way before; I do not doubt that they thought me some new kind of ant-nest, since these structures are alike only as their purpose in life is identical—for they express every possible variation in shape, size, color, design, and position. As for their curiosity, I could make no complaint, for, at best, my visitors could not be so inquisitive as I, inasmuch as I had crossed one ocean and two continents with no greater object than to pry into their personal and civic affairs as well as those of their neighbors. To say nothing of their environment and other matters.

That my rope slipped was the direct result of my own inefficiency. The hammock protects one from the dangers of the outside world, but like any man-made structure, it shows evidences of those imperfections which are part and parcel of human nature, and serve, no doubt, to make it interesting. But one may at least strive for perfection by being careful. Therefore tie the ropes of your hammock yourself, or examine and test the job done for you. The master of hammocks makes a knot the name of which I do not know—I cannot so much as describe it. But I would like to twist it again—two quick turns, a push and a pull; then, the greater the strain put upon it, the greater its resistance.

This trustworthiness commands respect and admiration, but it is in the morning that one feels the glow of real gratitude; for, in striking camp at dawn, one has but to give a single jerk and the rope is straightened out, without so much as a second's delay. It is the tying, however, which must be well done—this I learned from bitter experience.

It was one morning, years ago, but the memory of it is with me still, vivid and painful. One of the party had left her hammock, which was tied securely since she was skilful in such matters, to sit down and rest in another, belonging to a servant. This was slung at one end of a high, tropical porch, which was without the railing that surrounds the more pretentious verandahs of civilization, so that the hammock swung free, first over the rough flooring, then a little out over the yard itself. A rope slipped, the faulty knot gave way, and she fell backward—a seven-foot fall with no support of any kind by which she might save herself. A broken wrist was the price she had to pay for another's carelessness—a broken wrist which, in civilization, is perhaps, one of the lesser tragedies; but this was in the very heart of the Guiana wilderness. Many hours from ether and surgical skill, such an accident assumes alarming proportions. Therefore, I repeat my warning: tie your knots or examine them.

It is true, that, when all is said and done, a dweller in hammocks may bring upon himself any number of diverse dangers of a character never described in books or imagined in fiction. A fellow naturalist of mine never lost an opportunity to set innumerable traps for the lesser jungle-folk, such as mice and opossums, all of which he religiously measured and skinned, so that each, in its death, should add its mite to human knowledge. As a fisherman runs out set lines, so would he place his traps in a circle under his hammock, using a cord to tie each and every one to the meshes. This done, it was his custom to lie at ease and wait for the click below which would usher in a new specimen,—perhaps a new species,—to be lifted up, removed, and safely cached until morning. This strategic method served a double purpose: it conserved natural energy, and it protected the catch. For if the traps were set in the jungle and trustfully confided to its care until the break of day, the ants would leave a beautifully cleaned skeleton, intact, all unnecessarily entrapped.

Now it happened that once, when he had set his nocturnal traps, he straightway went to sleep in the midst of all the small jungle people who were calling for mates and new life, so that he did not hear the click which was to warn him that another little beast of fur had come unawares upon his death. But he heard, suddenly, a disturbance in the low ferns beneath his hammock. He reached over and caught hold of one of the cords, finding the attendant trap heavy with prey. He was on the point of feeling his way to the trap itself, when instead, by some subconscious prompting, he reached over and snapped on his flashlight. And there before him, hanging in mid-air, striking viciously at his fingers which were just beyond its reach, was a young fer-de-lance—one of the deadliest of tropical serpents. His nerves gave way, and with a crash the trap fell to the ground where he could hear it stirring and thrashing about among the dead leaves. This ominous rustling did not encourage sleep; he lay there for a long time listening,—and every minute is longer in the darkness,—while his hammock quivered and trembled with the reaction.
