A young man, a student in one of our universities, was one day taking a walk with a professor, who was commonly called the students’ friend, for his kindness to those who waited on his instructions．
　   As they went along, they saw   21   in the path a pair of old shoes, which they supposed to belong to a poor man who was employed in a field close by, and who had   22   finished his day’s work．
　The student   23   the professor, saying, “Let’s play the man a（n）   24  : we will hide his shoes, and we stay behind those bushes, and wait to see his  25   when he cannot find them.”
　  “My young friend,” answered the professor, “we should never  26   ourselves at the expense of the poor．You are   27  , and may give yourself a much greater pleasure by means of helping the poor man．Put a  28   into each shoe, and then we will hide ourselves and watch how the   29   affects him.”
　  The student did so,  30   they both placed themselves behind the bushes close by．
　  The poor man soon finished his work, and came   31   the field to the path where he had left his coat and shoes．While   32   his coat he slipped his foot into one of his shoes; but feeling something 33  , he bent down to feel what it was, and found the coin．
　  Astonishment and wonder were seen upon his face．He gazed upon the coin, turned it round, and looked at it again and again．He then looked around 34   on all sides, but no person was to be seen．He now put the money into his pocket, and went on to put on the other shoe; but his surprise was  35   on finding the other coin．
　  His feelings   36   him; he fell upon his  37  , looked up to heaven and let out a sincere thanksgiving, in which he spoke of his wife, sick and  38  , and his children without bread, whom the timely giving, from some unknown hand, would save from dying．
　  The student stood there deeply affected, his eyes filled with tears．“Now,” said the professor,
“Are you not much better pleased than if you had played your  39   trick?” The youth replied, “You have taught me a lesson which I will never forget．I feel now the  40  of those words, which I never understood before: ‘It is more blessed to give than to receive.’”
