rising flood tore at them and carried away great portions with a splash
and a gurgle.

"The island's much smaller than when we landed," said the accurate
Swede. "It won't last long at this rate. We'd better drag the canoe
close to the tent, and be ready to start at a moment's notice. _I_ shall
sleep in my clothes."

He was a little distance off, climbing along the bank, and I heard his
rather jolly laugh as he spoke.

"By Jove!" I heard him call, a moment later, and turned to see what had
caused his exclamation; but for the moment he was hidden by the willows,
and I could not find him.

"What in the world's this?" I heard him cry again, and this time his
voice had become serious.

I ran up quickly and joined him on the bank. He was looking over the
river, pointing at something in the water.

"Good Heavens, it's a man's body!" he cried excitedly. "Look!"

A black thing, turning over and over in the foaming waves, swept rapidly
past. It kept disappearing and coming up to the surface again. It was
about twenty feet from the shore, and just as it was opposite to where
we stood it lurched round and looked straight at us. We saw its eyes
reflecting the sunset, and gleaming an odd yellow as the body turned
over. Then it gave a swift, gulping plunge, and dived out of sight in a
flash.
