On the fourth morning there came a break in the clouds, and the sight of a high hill gave Leif the clue for his reckoning. The prows swung seaward, and the galleys steered for the broad ocean. That afternoon there sprang up the north-east wind for which they had been waiting. Sails were hoisted on the short masts,oars were shipped and lashed under the bulwarks, and the thralls clustered in the prows to rest their weary limbs and dice with knucklebones. The spirits of all lightened, and there was loud talk in the sterns among the Bearsarks. In the night the wind freshened, and the long shallow boats rolled filthily so that the teeth shook in a man's head, and over the swish of the waves and the creaking of the sheets there was a perpetual din of arms clashing. Biorn was miserably ill for some hours, and made sport for the seasoned voyagers.
