He had been compelled to fight often for his life and again to flee for it from an enemy who reserved torture and death for the captured.

Dick felt that he must do as well, and the feeling increased his vigor and courage.
A little later he heard a note, low, faint and musical.

It was behind him, but he was sure at first that it was made by negroes singing.

It was a pleasing sound.

The negro had a great capacity for happiness, and Dick as a young lad had played with and liked the young colored lads of his age.
But as he walked on he heard the low, musical note once more and, as before, directly behind him.
