It is sweet to see how soon a spring becomes a rill, and a rill runs on into a rivulet, and a rivulet swells into a brook; and before one has time to say 'what are you at?' - before the first tree it ever spoke to is a dummy, or the first hill it ever ran down has turned blue, here we all have airs and graces, demands and assertions of a full grown river.
