in this fashion for several
hundred feet, when he was dragged beneath the surface.

I swam doggedly on, hoping that that was the last unattached shark.
But there was another. Whether it was one that had attacked the natives
earlier, or whether it was one that had made a good meal elsewhere, I do
not know. At any rate, he was not in such haste as the others. I could
not swim so rapidly now, for a large part of my effort was devoted to
keeping track of him. I was watching him when he made his first attack.
By good luck I got both hands on his nose, and, though his momentum
nearly shoved me under, I managed to keep him off. He veered clear,
and began circling about again. A second time I escaped him by the same
manoeuvre. The third rush was a miss on both sides. He sheered at the
moment my hands should have landed on his nose, but his sandpaper hide
(I had on a sleeveless undershirt) scraped the skin off one arm from
elbow to shoulder.

By this time I was played out, and gave up hope. The schooner was still
two hundred feet away. My face was in the water, and I was watching him
manoeuvre for another attempt, when I saw a brown body pass between us.
It was Otoo.

"Swim for the schooner, master!" he said. And he spoke gayly, as though
the affair was a mere lark. "I know sharks. The shark is my brother."

I obeyed, swimming slowly on, while Otoo swam about me, keeping always
between me and the shark, foiling his rushes and encouraging me.

"The davit tackle carried away, and they are rigging the falls," he
explained, a minute or so later, and then went under to head off another
attack.

By the time the schooner was thirty feet away I was about done for. I
could scarcely move. They were heaving lines at us from on board, but
they continually fell short. The shark, finding that it was receiving no
hurt, had become bolder. Several times it nearly got me, but each time
Otoo was there just the moment before it was too late. Of course, Otoo
could have saved himself any time. But he stuck by me.

"Good-by, Charley! I'm finished!" I just managed to gasp.

I knew that the end had come, and that the next moment I should throw up
my hands and go down.

But Otoo laughed in my face, saying:

"I will show you a new trick. I will make that shark feel sick!"

He dropped in behind me, where the shark was preparing to come at me.

"A little more to the left!" he next called out. "There is a line there
on the water. To the left,
