While rare with us, this animal sometimes appears in the northern waters in immense shoals, following in the wake of the mackerel, which constitutes its selected food. In this condition it does not hesitate to enter the pounds and weirs, or to nav- igate between the piles of wharves, darting with the swiftness of an arrow into the midst of its prey, and pouncing upon the neck of a selected victim.
