the breeding season, and obtain their living by following the shoals of fishes which approach the shallows to spawn, especially the herrings, sprats, &c. These they catch with, great ease and certainty by diving, pursuing their prey with swiftness beneath the surface. Dr. Richardson found the Northern Diver more abundant on the interior lakes of Arctic America than in the ocean; he says it destroys vast quantities of fish.

Its loud and very melancholy cry, like the howling of the wolf, and at times like the distant scream of a man in distress, is said to portend rain. Its flesh is dark, tough, and unpalatable."
The following interesting account of the manners of this species in captivity is given by Mr. Nuttall of Boston. "A young bird of this species which I obtained in the Salt Marsh at Chelsea Beach, and transferred to a fish-pond, made a good deal of plaint, and would sometimes wander out of his more natural element, and hide and bask in the grass.
