answer was perfectly correct and he added: "I feel very proud to know that one of the class has been so very diligent. I rejoice to think that this pupil is so modest, for he is not anxious to disclose his identity. The true scholar is always humble."
Again that day he set a new question, more difficult than the one set on the previous day. Again the same result ensued. The correct answer was written on the table opposite to the teacher's place. He again asked, "Who has written this answer!" The pupils were silent. For a third time a fresh problem was set. The teacher now determined to find out the intelligent and modest pupil whose answers had been so accurate. He bored a small hole in the wall and watched events from the next room. When all the students had left the class-room he saw a stranger leave the corner and advance to the table. He was dressed in threadbare garments and looked very famished. He saw him write out the answer and then return to the comer, where he fell asleep. The teacher had seen enough. He now knew why his own pupils had not been able to admit that one of them had written the answers to his questions.
Next morning he repeated his usual question, "Who has written this answer on my table?" Once more there was silence. He now requested the stranger to come forward. The latter immediately did as he was bidden.
"Did you write this answer to my question?"
