The fire had reached the tree tops in one section of the woods. Crouch called their attention to that particular area. It was a sight which would never be forgotten by either Bill or Bob. They were looking at one of the most terrifying of all kinds of forest fires—a crown fire. The flames seemed to be alive. They acted as if guided by some diabolical hand as they carried their destruction onward. They leaped from tree top to tree top with an incredible speed. At times their motion was almost too rapid for the eye to follow. A sheet of flames covered the tops of all the trees in that particular part of the forest so completely that the green foliage below was completely hidden.
