“Hallo!” I shouted.

“Can’t seem to get along here.”

I stopped to watch him, and then a cold shudder ran through me, for I could see that though he was swimming with his face toward me, he was slowly gliding away by the trees on the opposite bank.

“He has got into the current,” I thought; and I was going to shout a warning, but I had the good sense not to do so, for I felt that it would alarm him, and beginning to swim back, I cried—

“Turn in for the shore.”

“Eh?”

“Make for the shore.”

“Can’t, lad,” came back; and the cold chill I had before felt thrilled me; while feeling as if I dared not speak, I swam towards him, in agony all the time, for fear I should get into the current with which he was struggling.

“Don’t get much nearer,” he shouted, coolly enough, for he had not yet realised his clanger; and making an effort to speak as calmly, I raised my voice and shouted—

“Of course you don’t. Turn round and swim the other way, sloping for the bank.”
