He went below. In a few minutes he re-appeared, his face deadly pale. “Blowhard,” he said, “the ship is sinking. One of the pirates (sheer accident, of course, I blame no one) has kicked a hole in the side. Let us sound the well.”

We put our ear to the ship’s well. It sounded like water.

The men were put to the pumps and worked with the frenzied effort which only those who have been drowned in a sinking ship can understand.

At six p.m. the well marked one half an inch of water, at nightfall three-quarters of an inch, and at daybreak, after a night of unremitting toil, seven-eighths of an inch.

By noon of the next day the water had risen to fifteen-sixteenths of an inch, and on the next night the sounding showed thirty-one thirty-seconds of an inch of water in the hold. The situation was desperate. At this rate of increase few, if any, could tell where it would rise to in a few days.

That night the Captain called me to his cabin. He had a book of mathematical tables in front of him, and great sheets of vulgar fractions littered the floor on all sides.

“The ship is bound to sink,” he said, “in fact, Blowhard, she is sinking. I can prove it. It may be six months or it may take years, but if she goes on like this, sink she must. There is nothing for it but to abandon her.”

That night, in the dead of darkness, while the crew were busy at the pumps, the Captain and I built a raft.

Unobserved we cut down the masts, chopped them into suitable lengths, laid them crosswise in a pile and lashed them tightly together with bootlaces.

Hastily we threw on board a couple of boxes of food and bottles of drinking fluid, a sextant, a cronometer, a gas-meter, a bicycle pump and a few other scientific instruments. Then taking advantage of a roll in the motion of the ship, we launched the raft, lowered ourselves upon a line, and under cover of the heavy dark of a tropical night, we paddled away from the doomed vessel.
