The galley[2] rode the waves with the bold freedom of her kind. Her keel was carved out of a single great tree. Her seasoned oaken timbers, overlapping, were riveted together by iron bolts, with the round heads outside. Where a timber touched a rib, a strip was cut out on each side, forming a block through which a hole was bored. Another hole was bored in the rib to match and a rope twisted of the inner bark of the linden was put through both holes and knotted. In surf or heavy sea, this construction gave the craft a supple strength. Calking was done with woolen cloth steeped in pitch. The mast, of a chosen trunk of fir, was set upright in a log with ends shaped like a fishtail. The long oarlike rudder was on the board or side of the ship to the right of the stern, called the starboard or steerboard. The lading was done on the opposite side, the larboard or ladderboard. There were ten oars to a side, and a single large triangular sail. Long and narrow, hardly ten feet above the water-line at her lowest, her curved prow glancing over the waves like the head of a swimming snake, she was no more like the tumbling cargo-ships than a shark is like a porpoise. When they were two days out, Nils said to Thorolf, "A Viking in such a galley would sail to the end of the world. By the way, did the Skroelings in Greenland understand that language the Wind-wife spoke?" "I was not there long enough to find out. I once asked a man who knows their talk well, and he said it was no tongue that ever he heard." The Greenland folk welcomed them heartily. Finding that the white men had not after all been forgotten by their own people, the natives drew off and gave them no more trouble. The Northmen spent the winter in sleep, talk, song, and hunting with native guides. Besides the old man in white fur, as the polar bear was respectfully called, Arctic foxes, walrus, whales and seal abounded. Many of the new-comers became skilful in the making and the use of the skin-covered native boats called Kayaks. Nils had some skill in carving wood and stone, and could write in the Runic script of Elfdal. In the long evenings when winds from the cave of the Great Bear buffeted the low huts, he taught Thorolf and Anders what he knew, and talked with the Skroelings. But none of them understood the runes of the Wind-wife. Their speech was quite different. Spring came with brief, hot sunshine, and the creeping birches budded on the pebbly shore. Encouraged by the reports from Greenland, new colonists ventured out, and house-building went on briskly. One day Thorolf was summoned to Knutson's headquarters. "Erlandsson," began the Chevalier, "they say that you have information about Vinland[3] and the Skroelings there, from an old woman who lived among them. What can you tell me?" Thorolf told the story of the Wind-wife. Knutson looked interested but doubtful.
