So the boy thanked her, and he fastened on the Shoes of Swiftness, and turned to say good-by to the young man and the lady. But, behold! they had vanished, he knew not how or where! Then he leaped in the air to try the Shoes of Swiftness, and they carried him more swiftly than the wind, over the warm blue sea, over the happy lands of the south, over the northern peoples who drank mare’s milk and lived in great wagons, wandering after their flocks. Across the wide rivers, where the wild fowl rose and fled before him, and over the plains and the cold North Sea he went, over the fields of snow and the hills of ice, to a place where the world ends, and all water is frozen, and there are no men, nor beasts, nor any green grass. There in a blue cave of the ice he found the Three Gray Sisters, the oldest of living things. Their hair was as white as the snow, and their flesh of an icy blue, and they mumbled and nodded in a kind of dream, and their frozen breath hung round them like a cloud. Now the opening of the cave in the ice was narrow, and it was not easy to pass in without touching one of the Gray Sisters. But, floating on the Shoes of Swiftness, the boy just managed to steal in, and waited till one of the sisters said to another, who had their one eye: “Sister, what do you see? do you see old times coming back?” “No, sister.” “Then give _me_ the eye, for perhaps I can see farther than you.” Then the first sister passed the eye to the second, but as the second groped for it the boy caught it cleverly out of her hand. “Where is the eye, sister?” said the second gray woman. “You have taken it yourself, sister,” said the first gray woman. “Have you lost the eye, sister? have you lost the eye?” said the third gray woman; “shall we _never_ find it again, and see old times coming back?” Then the boy slipped from behind them out of the cold cave into the air, and he laughed aloud. When the gray women heard that laugh they began to weep, for now they knew that a stranger had robbed them, and that they could not help themselves, and their tears froze as they fell from the hollows where no eyes were, and rattled on the icy ground of the cave. Then they began to implore the boy to give them their eye back again, and he could not help being sorry for them, they were so pitiful. But he said he would never give them the eye till they told him the way to the Fairies of the Garden.
