He stood motionless in an agony of fear.

His breath whistled between his teeth.

The perspiration ran down his face and body in little streams.
Something big, black, and heavy came crashing through the swamp close to him, and with a yell of utter panic Freckles ran--how far he did not know; but at last he gained control over himself and retraced his steps.
His jaws set stiffly and the sweat dried on his body.

When he reached the place from which he had started to run, he turned and with measured steps made his way down the line.

After a time he realized that he was only walking, so he faced that sea of horrors again.
