Running into the garden, Dick made out a dim form in the distance, on the path leading to the lake.

"There he is!" he cried. "Come, Tom, we must catch him, if we can!"

Josiah Crabtree branched off onto the road leading into Cedarville.
Then of a sudden the shadows of a patch of woods hid him from view.
