But though he now had little more to learn in his craft, the Lad, when the shoe was made, picked it up in his pincers and flung it to the other end of the forge; yet the King now knew enough to know that few smiths could have made its equal. So he looked surprised; at which the Lad, controlling himself, said:
"When I pass your fourth shoe you will need no more masters—I forged a shoe like that one yonder when I was fifteen, and my father said of it, You will make a smith one day.'"
And on neither Tuesday nor Wednesday nor Thursday nor Friday could the King succeed in pleasing the Lad; the better his shoes the angrier grew his young master that they were not good enough. Yet between these gusts of temper he was gentle and remorseful, and once the King saw tears in his eyes, and another time the Lad came humbly to ask for pardon. Then William laughed and put out his hand, but, as once before, the Lad slipped his behind his back and said:
"It is so dirty, friend."
And this time he would not let William take it. So the King was forced instead to lay his arm about the Lad's shoulder, and press it tenderly; but the Lad made no response, and only stood hanging his head until the King removed his arm. All the same, when next the King made a shoe he was full of rage, and stamped on it, and ran out of the forge. Which surprised the King all the more because it was so excellent a shoe. Yet he was secretly glad of its rejection, for he felt it would break his heart to go away from that place; and he could think of no good cause for remaining, once Pepper was shod. So there he stayed, eating, sleeping, and working, while the thews of his back became as strong under the smooth skin as the thews of a beech-tree under the smooth bark; and his craft was such that the Lad at last left the whole of the work of the forge in his charge. For there was nothing he could not do surpassingly well. And this the Lad admitted, save only in the case of the fourth shoe.
But on Saturday, just before closing-time, the King set to and made a shoe so fine that when the Lad saw it he said quietly, "I could not make a better." Had he not said so he must have lied, or proved that he did know a masterpiece when he saw it. And he too good a craftsman for that, besides being honest.
Pepper instantly lifted up her near hind-foot.
"Upon my word!" exclaimed the King, "the world is full of stones, and Pepper has found them all. The wonder is that she did not fall down on the road."
"This is not a stone," said the Lad, "it is an opal."
And he displayed an opal of such marvelous changeability, such milk and fire shot with such shifting rainbows, that it was as though it had had birth of all the moods of all the women of all time.
