within ten feet of him, but in the twilight did not notice him. It was
enough to make one quiver. Another passed a little later, and he, too,
failed to see the fugitive. But a third, if he came, would probably
see, and leaving the tumulus Ned ran to another where he hid again for
a few minutes.

It was the boy's object to make off through the neighboring forest after
