Read the excerpt from The Wind in the Willows by Kenneth Grahame.

Never in his life had he seen a river before—this sleek, sinuous, full-bodied
animal, chasing and chuckling, gripping things with a gurgle and
leaving them with a laugh, to fling itself on fresh playmates that
shook themselves free, and were caught and held again. All was a-shake
and a-shiver—glints and gleams and sparkles, rustle and swirl,
chatter and bubble. The Mole was bewitched, entranced, fascinated.
