"There's the 'Marie,'" he cried. Phil raised his voice in a good lusty howl for help, but none heard him. He could see the lights of the steamboat and they appeared to be far away.

"There is only one thing left for me to do, and that is to strike out for the shore. I wonder which way the shore is?"

Once more he raised himself in the water, for an instant, and gazed toward the rapidly disappearing lights of the 'Marie.'

"She is going downstream, so if I swim to the left I should reach shore after a while," decided the lad.

He did not know that the boat had in the meantime made a sharp turn to her right and that in turning to the left he would be swimming downstream, making his attempt to reach shore a difficult one indeed.

The lad struck out manfully, swimming with long, easy strokes, aided considerably by the current which was sweeping him downstream much faster than he thought.

"I'm glad I have only my pajamas on," decided the lad. "If I had all my clothes on I fear I should have a pretty tough fight. It's bad enough as it is."

Talking to himself, in order to keep up his courage, he swam steadily on, now and then pausing to swim on his back to rest himself. He had gone on for nearly an hour when the lad began to wonder why he had not reached shore.

"Surely the river cannot be so wide at this point. I must have drifted downstream considerably. Perhaps I haven't been going in the right direction at all."

He tried to find out which way the drift was, in order to make up his mind as to the direction in which the shore lay. In the darkness, however, he was unable to determine this, so he began swimming again, trusting to luck to land him on something solid, sooner or later. He knew that this must occur, but whether his strength would hold out that long he could not say.
