Behind him came his two men in a queer snakelike procession of plopping buoys and wriggling bodies. Ahead of them the seaweed stretched, apparently all the way to the schooner. As they worked their way through the scum of many seas, the noon sun broiled their backs into thin water blisters, and stewed saline odors out of the clammy life about them.
Once Madden's hand struck a yellowish line of algae and a score or two of little jelly-like insects writhed into the grass below. One of these things touched the swimmer's arm and gave the boy a stinging sensation. He knocked it off desperately and pushed on.
Presently his shoulder muscles ached and burned so keenly, he could no longer continue the overarm. Then he took the buoy in both hands, held it straight out, thrust it edge down into the oozy substance, used it as a kind of anchor and drew it to him. At first this technique seemed to advance him somewhat, but presently he appeared merely to disturb the viscous mass without going forward. He grew acutely discouraged; his back, shoulders, cramped, ached and burned. The brilliantly lighted schooner seemed to regress as he progressed. The sun was like an auger boring into the back of his head. His mind began to wander again, and a sudden fear came on him lest he should go insane out in this horrible slime.
A fiery burning on his right foot jerked him back out of his half delirium, and he knew that an insect of the same kind he had seen a few minutes before had stung him. He kicked it off convulsively, but the thrust of his foot brought a wash of new stings.
All of a sudden, his patience, endurance, pluck seemed to give out. This new torture made him as unreasonably frantic as a baby. He kicked furiously. He scraped the toe nails of one foot against the flesh of the other leg. As he did so the animalculae settled on the abraded skin, like streaks of melted steel. The boy doubled up, like a grub worm covered with ants, fighting, scraping, twisting, squirming. He writhed, beat, scratched, this great hundred and sixty pound animal fighting an enemy that would weigh about twenty to the gram.
He heard a shout from Caradoc, a question from Greer, then his insane struggles carried him under the surface of the clammy seaweed. The seaweed, infested with stinging insects, closed over his form like a wave of fire.
Only lack of breath stopped Leonard's mad struggles. Bursting lungs and the mere necessity to live at last made him disregard the attacks of these wasps of the Sargasso. He struck out for the surface again like a diver, reaching up arms, spreading legs with a stroke and a kick. But the gelatinous stuff simply quivered with his struggles and held him firm. He stuck like a fly in mucilage.
The sliminess of the element utterly destroyed the mechanics of swimming. A forward stroke in pure water displaces portions of the water and the return stroke sends the body forward. In this mass the forward stroke merely compressed the weed in front of the arm, and left a cavity through which the return stroke received no power.
Madden dared not open his eyes. In fiery blackness he kicked and struck in useless froglike movements. His heart was beating like a trip-hammer in his ears. Streaks of red fire played against the blackness of his eyelids. He knew that in a few more seconds his straining lungs would gulp in the stinging ooze, he knew his will could not prevent his drawing in some sort of breath.
He clung desperately to the control of his diaphragm, as a falling man clings to a ledge of rock. His great chest muscles gave convulsive jerks. His control was going, going.
