When he came home he put the necklace into the mortar, just as he had done the ring, and ground it up and ground it up until it was as fine as the dust on the shelf. There! he thought, that is an end of the Clever Student at any rate. Then he went back to his books, and it was not long before he found that he had been tricked again. “I can make no more changes,” said the Student, “for I am nearly at the end of my arts. The Black Master will be wanting your ear-drop when he comes, but, instead of giving it to him, throw it against the wall as hard as you can. After that we shall have to trust to good Mother Luck.” It was not long before the Master of Black Arts came with his basket on his arm, just as he had done twice before; he opened the basket, and there was a grey goose. “Only a grey goose!” you say? Wait a moment, and you shall see that it was not like any grey goose in our town! The Master of Black Arts stood the grey goose on the table; “Flickety-whickety!” said he. “Cackle! cackle!” said the grey goose, and every time it said “cackle” a bright diamond dropped on the table. When the king saw that he rubbed his hands and rubbed his hands, and could not say enough of thanks to the Master of Black Arts. And what would the Master have now? He had only to ask and it was his. “Oh!” says the Master of Black Arts, “the princess has a pearl ear-drop that I have taken a liking to; if I may have that I will be quite satisfied.” So the princess was sent for, and this time she was not so willing to let the Master have what he wanted. She wept and begged, and begged and wept; but it was all to no purpose; the Master of Black Arts wanted the pearl ear-drop, and the Master of Black Arts must have it—that was what the king said. So at last the princess took the pearl ear-drop out of her ear, but, instead of giving it to the Master, she threw it against the wall as hard as she was able, just as the Clever Student had told her to do. And then what do you think happened? Why, the Student turned himself into a ripe melon, so that when it struck the wall it burst open and the seeds that were inside were scattered all over the floor. But the Master of Black Arts knew a trick as good as that. He changed himself into a great red cock, and began pecking away at the seeds, gobbling them up as fast as he could. By and by he looked around, and not another seed could he see, whereupon he hopped up on a chair and, shutting his eyes and flapping his wings, he crowed “cock-a-doodle-do!” But listen! One melon-seed had rolled into a crack in the floor, and the cock had not seen it. That was a bad thing for him, for while his eyes were shut and he was crowing “cock-a-doodle-do!” the Clever Student changed himself from the melon-seed into a great fox. Up he jumped—snip! snap!—and off flew the cock’s head, and there was an end of it and of the Master of Black Arts.
