Very soon the forest lay all about them, with the birds singing over their heads, and with numberless tiny feet scurrying through the underbrush on all sides.

Just out of sight a brook babbled noisily of its delight in being alive; and away up in the treetops the morning sun played hide-and-seek among the dancing leaves.
And David leaped, and laughed, and loved it all, nor was any of it strange to him.

The birds, the trees, the sun, the brook, the scurrying little creatures of the forest, all were friends of his.

But the man--the man did not leap or laugh, though he, too, loved it all.

The man was afraid.
He knew now that he had undertaken more than he could carry out.
