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. 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.
