SALMON

Loke saw that he now had only two chances of escape,—either to risk his life and swim out to sea, or to leap again over the net. He chose the latter, and made a tremendous leap over the top line of the net. Thor grasped after him and caught him, but he slipped in his hand so that Thor did not get a firm hold before he got to the tail, and this is the reason why the salmon has so slim a tail.
