so the rich man was obliged to put his brother’s turnip in a cart and have it taken to his home. when there he did not know on whom to vent his rage and anger, until bad thoughts came to him, and he resolved to kill his brother. he hired murderers, who were to lie in ambush, and then he went to his brother and said, "dear brother, i know of a hidden treasure, we will dig it up together, and divide it between us." the other agreed to this, and accompanied him without suspicion. while they were on their way, however, the murderers fell on him, bound him, and would have hanged him to a tree. but just as they were doing this, loud singing and the sound of a horse’s feet were heard in the distance. on this their hearts were filled with terror, and they pushed their prisoner head first into the sack, hung it on a branch, and took to flight. he, however, worked up there until he had made a hole in the sack through which he could put his head. the man who was coming by was no other than a travelling student, a young fellow who rode on his way through the wood joyously singing his song. when he who was aloft saw that someone was passing below him, he cried, "good day! you have come at a lucky time." the student looked round on every side, but did not know whence the voice came. at last he said, "who calls me?" then an answer came from the top of the tree, "raise your eyes; here i sit aloft in the sack of wisdom. in a short time have i learnt great things; compared with this all schools are a jest; in a very short time i shall have learnt everything, and shall descend wiser than all other men. i understand the stars, and the signs of the zodiac, and the tracks of the winds, the sand of the sea, the healing of illness, and the virtues of all herbs, birds, and stones. if you were once within it you would feel what noble things issue forth from the sack of knowledge."
