A swinging ladder, whose foot was clear of the floor, led down into the recesses. A diver, having completed his task, ascended the treacherous staircase to escape, and found the hatch blocked up. A floating chest or box had drifted into the opening, and, fitting closely, had firmly corked the man up in that dungeon, tight as a fly in a bottle. From his doubtful perch on the ladder he endeavored to push the obstacle from its insertion. Two or more equal difficulties made this impossible. The box had no handle, and it was slippery with the ooze and mucus of the sea. The leverage of pushing only wedged it faster in the orifice. The inconstant ladder swayed from it as a fulcrum. Again and again by art and endeavor and angle of push he essayed, and the ladder made sport of it. It was deadly sport, that swing and seesaw on the slippery rungs in the immeasurable loneliness of the silent, shrouded cabin. It was no rush of air, sending life tingling in the blood made brilliant with carmine of oxidation, but the dense, mephitic sough of the thick wool of water. He descended and sat upon the floor to think. Feasible methods had failed, and the sands of his life were running out like the old physician's. Now to try the impracticable. There are heaps of wisdom in the wrong way sometimes, which, I suppose, is the reason some of us like it. The box was out of his reach, choked in the gullet of that life-hole. No spring or leap from floor or ladder could reach its slippery side or bear it from its fixture. The sea had caught him prowling in its mysteries, and blocked him up, as cruel lords of ancient days walled up the intruder on their domestic privacy. Wit after brute force: man and Nature were pitted against each other in the uncongenial gloom--life the stake. He groped about his prison, glutinous with infusoriae and the oily consistence of the sea. Here a nail, there a block or lever, shaped out mentally by the touch, theorized, studied upon and thrown down. Now a hatchet, monkey-wrench, monkey's-tail, or gliding fish or wriggling eel, companions of his imprisonment. At last the cold touch of iron: the hand encloses and lifts it; its weight betrays its length; he feels it to the end--blunt, square, useless. He tries the other end--an edge or spike. That will do. Standing under the hatch, guided by the ladder to the position, and with a strong swinging, upward blow, the new tool is driven into the soft, fibrous and adhesive pine bottom of the box. On the principle on which your butler's practiced elbow draws the twisted screw sunk into the cobwebbed seal of your '48 port, he uncorks himself. The box pulled out of the hatch, the sea-gods threw up the sponge, that zoophyte being handy.
