One other accomplishment he acquired from Skipper Ed. He learned to swim. Even in midsummer these northern waters are icy cold. From the breaking up of the ice in summer until the sea freezes again in winter, the natives spend their time upon the water or near it, yet it is rare, indeed, that one of them can swim. And so it was with Abel. He had never in his life voluntarily gone into the sea. But Skipper Ed was a mighty swimmer, and under his instruction Jimmy had learned the art, and in the fourth summer after Bobby's arrival nothing would do but he, too, must learn. Much perseverance was necessary before Abel and Mrs. Abel gave their consent, but finally it was obtained, and in a little while Bobby was as keen for a dip and a dive and a swim as were Skipper Ed and his partner, Jimmy.
