March 16.—Fine, clear, dazzling morning, the sun an hour high, the air just tart enough. What a stamp in advance my whole day receives from the song of that meadow lark perch'd on a fence-stake twenty rods distant! Two or three liquid-simple notes, repeated at intervals, full of careless happiness and hope. With its peculiar shimmering slow progress and rapid-noiseless action of the wings, it flies on a way, lights on another stake, and so on to another, shimmering and singing many minutes.
