“In the first place buy thyself an A.B.C. book of the kind which has a cock on the frontispiece: in the second, turn thy cart and thy two oxen into money, and get thyself some clothes, and whatsoever else pertains to medicine; thirdly, have a sign painted for thyself with the words, ‘I am Doctor Knowall,’ and have that nailed up above thy house-door.” The peasant did everything that he had been told to do. When he had doctored people awhile, but not long, a rich and great lord had some money stolen. Then he was told about Doctor Knowall who lived in such and such a village, and must know what had become of the money. So the lord had the horses put in his carriage, drove out to the village, and asked Crabb if he were Doctor Knowall? Yes, he was, he said. Then he was to go with him and bring back the stolen money.
