The Prisoners of the Pitcher-plant

Previous

T the edge of a rough piece of open, where the scrubby bushes which clothed the plain gave space a little to the weeds and harsh grasses, stood the clustering pitchers of a fine young sarracenia. These pitchers, which were its leaves, were of a light, cool green, vividly veined with crimson and shading into a bronzy red about the lip and throat. They were of all sizes, being at all stages of growth; and the largest, which had now, on the edge of summer, but barely attained maturity, were about six inches in length and an inch and a quarter in extreme diameter. Down in the very heart of the cluster, hardly to be discerned, was a tiny red-tipped bud, destined to shoot up, later in the season, into a sturdy flower-stalk.

Against the fresh, warm green of the sunlit world surrounding it, the sarracenia's peculiar colouring stood out conspicuously, its streaks and splashes of red having the effect of blossoms. This effect, at a season when bright-hued blooms were scarce, made the plant very attractive to any insects that chanced within view of it. There was nearly always some flutterer or hummer poising above it, or touching it eagerly to dart away again in disappointment. But every once in awhile some little wasp, or fly, or shining-winged beetle, or gauzy ichneumon, would alight on the alluring lip, pause, and peer down into the pitcher. As a rule the small investigator would venture farther and farther, till it disappeared. Then it never came out again.

"AT THIS MOMENT A PASSING SHRIKE SWOOPED DOWN." "AT THIS MOMENT A PASSING SHRIKE SWOOPED DOWN."

On a leaf of a huckleberry bush, overhanging the pitcher-plant, a little black ant was running about with the nimble curiosity of her kind. An orange and black butterfly, fluttering lazily in the sun, came close beside the leaf. At this moment a passing shrike swooped down and caught the butterfly in his beak. One of his long wings, chancing to strike the leaf, sent it whirling from its stem; and the ant fell directly upon one of the pitchers below.

It was far down upon the red, shining lip of the pitcher that she fell; and there she clung resolutely, her feet sinking into a sort of fur of smooth, whitish hairs. When she had quite recovered her equanimity she started to explore her new surroundings; and, because that was the easiest way to go, she went in the direction toward which the hairs all pointed. In a moment, therefore, she found herself just on the edge of the precipitous slope from the lip to the throat of the pitcher. Here, finding the slope strangely slippery, she thought it best to stop and retrace her steps. But when she attempted this she found it impossible. The little, innocent-looking hairs all pressed against her, thrusting her downward. The more she struggled, the more energetically and elastically they pushed back at her; till all at once she was forced over the round, smooth edge, and fell.

To her terrified amazement, it was water she fell into. The pitcher was about half full of the chilly fluid. In her kickings and twistings she brought herself to the walls of her green prison, and tried to clamber out,—but here, again, were those cruel hairs on guard to foil her. She tried to evade them, to break them down, to bite them off with her strong, sharp mandibles. At last, by a supreme effort, she managed to drag herself almost clear,—but only to be at once hurled back, and far out into the water, by the sharp recoil of her tormentors.

Though pretty well exhausted by now, she would not give up the struggle; and presently her convulsive efforts brought her alongside of a refuge. It was only the floating body of a dead moth, but to the ant it was a safe and ample raft. Eagerly she crept out upon it, and lay very still for awhile, recovering her strength. More fortunate than most shipwrecked voyagers, she had an edible raft and was therefore in no imminent peril of starvation.

The light that came through the veined, translucent walls of this watery prison was of an exquisite cool beryl, very different from the warm daylight overhead. The ant had never been in any such surroundings before, and was bewildered by the strangeness of them. After a brief rest she investigated minutely every corner of her queer retreat, and then, finding that there was nothing she could do to better the situation, she resumed her attitude of repose, with only the slight waving of her antennÆ to show that she was awake.

For a long time nothing happened. No winds were astir that day, and no sounds came down into the pitcher save the shrill, happy chirping of birds in the surrounding bushes. But suddenly the pitcher began to tip and rock slightly, and the water to wash within its coloured walls. Something had alighted on the pitcher's lip.

It was something comparatively heavy, that was evident. A moment or two later it came sliding down those treacherous hairs, and fell into the water with a great splash which nearly swept the ant from her refuge.

The new arrival was a bee. And now began a tremendous turmoil within the narrow prison. The bee struggled, whirled around on the surface with thrashing wings, and sent the water swashing in every direction, till the ant was nearly drowned. She hung to her raft, however, and waited philosophically for the hubbub to subside. At length the bee too, after half a dozen vain and exhausting struggles to climb out against the opposing array of hairs, encountered the body of the dead moth. Instantly she tried to raise herself upon it, so as to escape the chill of the water and dry her wings for flight. But she was too heavy. The moth sank, and rolled over, at the same time being thrust against the wall of the pitcher. The ant, in high indignation clutched a bundle of the hostile hairs in her mandibles, and held herself at anchor against the wall.

Thoroughly used up, and stupid with panic and chill, the bee kept on futilely grappling with the moth's body, which, in its turn, kept on sinking and rolling beneath her. A very few minutes of such disastrous folly sufficed to end the struggle, and soon the bee was floating, drowned and motionless, beside the moth. Then the ant, with satisfaction, returned to her refuge.

When things get started happening, they are quite apt to keep it up for awhile, as if events invited events. A large hunting spider, creeping among the grass and weeds, discovered the handsome cluster of the sarracenia. She was one of the few creatures who had learned the secret of the pitcher-plant and knew how to turn it to account. More than once had she found easy prey in some trapped insect struggling near the top of a well-filled pitcher.

Selecting the largest pitcher as the one most likely to yield results, the spider climbed its stem. Then she mounted the bright swell of the pitcher itself, whose smooth outer surface offered no obstacle to such visitors. The pitcher swayed and bowed. The water within washed heavily. And the ant, with new alarm, marked the big, black shadow of the spider creeping up the outside of her prison.

Having reached the lip of the leaf and cautiously crawled over upon it, the spider took no risks with those traitor hairs. She threw two or three stout cables of web across the lip; and then, with this secure anchorage by which to pull herself back, she ventured fearlessly down the steep of that perilous throat. One hooked claw, outstretched behind her, held aloft the cable which exuded from her spinnerets as she moved.

On the extreme of the slope she stopped, and her red, jewelled cluster of eyes glared fiercely down upon the little black ant. The latter shrank and crouched, and tried to hide herself under the side of the dead moth to escape the light of those baleful eyes. This new peril was one which appalled her far more than all the others she had encountered.

At this most critical of all crises in the destiny of the little black ant, the fickle Fortune of the Wild was seized with another whim. An overwhelming cataclysm descended suddenly upon the tiny world of the pitcher-plant. The soft, furry feet of some bounding monster—rabbit, fox, or wildcat—came down amongst the clustered pitchers, crushing several to bits and scattering wide the contents of all the rest. Among these latter was that which contained the little black ant. Drenched, astonished, but unhurt, she found herself lying in a tuft of splashed grass, once more free. Above her, on a grass-top, clung the bewildered spider. As it hung there, conspicuous to all the foraging world, a great black-and-yellow wasp pounced upon it, stung it into helplessness, and carried it off on heavily humming wing.
