The earth is the world of their greatest affection. There they are born, there they love; thither, when wounded, they retire to die. Thither they take their pregnant females, form for them their beds of sea-weed, and provide them with fish. They are very affectionate, good neighbors, mutually defending each other; only at their season of amours they are a little apt to fight. Each male has two or three females that he finds a home for on some mossy rock of sufficient extent. That is his estate, and he suffers no intrusion upon it. He knows how to maintain his right of proprietorship. The females are gentle and defenceless. If ill treated, they weep, are agitated and cast despairing glances upon the assailant. They are parturient during nine months, and nurse their young during five or six months, teaching them to swim, fish, and select the best food. No doubt they would keep them still longer, but the husband is jealous of his own progeny, fearing that the too weak mother will give him a rival. No doubt this brevity of education has limited the progress which the Seal would otherwise have made. Maternity is only complete when we come to the Sea Cow, an excellent family in which the parents have not the sad courage to drive away their young. The mothers nurse them for a long time; even while suckling a second, the mother still keeps by her the eldest, which, though it be a male, the father never ill treats, but seems to regard him with a love only second to that of the mother. This extreme tenderness, peculiar to that species, is exemplified in the physical progress made in the organization. In the Seal, a great swimmer, and in the heavy and clumsy sea Elephant the arms still continue to be fins; closely attached to the body are incapable of extension. But at length the Sea Cow, the _Sea Mama_ as the negroes call her, accomplishes the miracle. All extend and becomes pliant by a continuous effort. Nature exerts all her ingenuity upon the fixed idea of holding, pressing, caressing the young. The ligaments yield and extend, the fore arm appears and by and by appears the hand. And then the mother has the great, the supreme pleasure to press her young one to her breast. Here, then, are two things which may enable these amphibious creatures to make great progress. Already they have the hand, that organ of industry, that essential instrument of future toil. It must be supplied, must aid the work of the teeth as with the Beaver, and the Ant, will commence, at the outset, with building a home for the family. On the other hand, education, also, has become possible. The young one rests on the maternal bosom and, slowly drinking in her life, remains there a long time, and to an age when he can learn every thing,--all this depends on the kindness of the father who protects the innocent rival. And it is that which allows of progress.
