My mate and I were so pleased at that, we flew off a little way, chirping and chattering as we went. "Up and down, up and down," said Bobbie; "how prettily they fly." "Yes," said his mamma; "that is the way you can always tell a Goldfinch when in the air. A dip and a jerk, singing as he flies." "What other seeds do they eat, mamma?" presently asked Bobbie. "The seeds of the dandelion, the sunflower, and wild grasses generally. In the winter, when these are not to be had, the poor little fellows have a very hard time. People with kind hearts, scatter canary seed over their lawns to the merry birds for their summer songs, and for keeping down the weeds." THE GOLDFINCH. According to one intelligent observer, the Finches are, in Nature's economy, entrusted with the task of keeping the weeds in subjection, and the gay and elegant little Goldfinch is probably one of the most useful, for its food is found to consist, for the greater part, of seeds most hurtful to the works of man. "The charlock that so often chokes his cereal crops is partly kept in bounds by his vigilance, and the dock, whose rank vegetation would, if allowed to cast all its seeds, spread barrenness around, is also one of his store houses, and the rank grasses, at their seeding time, are his chief support." Another writer, whose study of this bird has been made with care, calls our American Goldfinch one of the loveliest of birds. With his elegant plumage, his rhythmical, undulatory flight, his beautiful song, and his more beautiful soul, he ought to be one of the best beloved, if not one of the most famous; but he has never yet had half his deserts. He is like the Chickadee, and yet different. He is not so extremely confiding, nor should I call him merry. But he is always cheerful, in spite of his so-called plaintive note, from which he gets one of his names, and always amiable. So far as I know, he never utters a harsh sound; even the young ones asking for food, use only smooth, musical tones. During the pairing season, his delight often becomes rapturous. To see him then, hovering and singing,--or, better still, to see the devoted pair hovering together, billing and singing,--is enough to do even a cynic good. The happy lovers! They have never read it in a book, but it is written on their hearts: "The gentle law that each should be The other's heaven and harmony."
