100:00 The medicinal properties of B. are mainly those of a mild tonic and pungent aromatic stimulant, and hence they are serviceable as a stomachic, in cases of weakness of the digestive organs. The taste is at first sweetish, rapidly becoming hot, aromatic, and bitter, and the odour is rather pleasant. The Angelica root yields a larger amount of the bitter principle than Angelica seeds. Camomile flowers, coriander-seeds, and other vegetable tonics and stimulants, are occasionally employed in the preparation of bitters.

It is common in many parts of North America, migrating northward and southward, according to the season. The crown of the head is reddish brown, and the colours and markings of the plumage differ considerably from those of the common B.The LEAST B.

The head and upper parts generally are purplish brown, except the wings, which are buff, conspicuously freckled with brown; the throat, breast, and belly mottled brown and buff.
