154 NATURAL HISTORY IN ANECDOTE, the whole space is occupied. Frequently a struggle ensues between two males for the possession of the same female, and both seizing her at once, pull her in two, or terribly lacerate her with their teeth. When the space is all filled, the old male walks around complacently reviewing his family, scolding those who crowd or disturb the others, and fiercely driving off all intruders. This surveillance always keeps him actively occupied.” After the birth of their young which takes place towards the end of July, the old males who have been four months without food, go to some distance from the shore to feed, teaching the young to swim on their return, “By the last of October the seals begin to leave the islands in small companies.
