He got out at Harvard Square, and crossing the street entered the college yard, or campus, as it is sometimes more ambitiously called. There were very few students about, for it was Saturday, when there was a morning exercise only, and, the rest of the day being a holiday, many of the students were accustomed to go to Boston, or to visit their friends elsewhere. Sam knew nothing of this, and was surprised to see so few young men about. Now it happened that three sophomores, having nothing more important to occupy their attention, had made up their minds, by way of a lark, to play a trick on some freshman, who, from inexperience, looked like an easy victim. For convenience's sake I will call them Brown, Jones and Robinson. As these three young men were walking arm-in-arm in front of University Hall, they saw Sam approaching. Of course, where the classes are so large, it is impossible for all to be personally acquainted, which accounts for their instantly mistaking Sam for a freshman. "There's a fresh," said Brown. "He looks green enough for our purpose. Suppose we take him?" "All right," said Jones. "He'll do." Sam was rather surprised when the three college boys stopped and Brown addressed him. "What is your name, sir?" "Barker," answered Sam. "All right!" said Robinson, in a low voice. "There's a Barker in the freshman class. I've noticed his name in the catalogue." "I believe, Mr. Barker," said Brown, "that you belong to the freshman class." "That's a good joke," said Sam to himself. "I'll see it through." He was not a little flattered at being mistaken for a collegian, and nodded assent. "We have heard of you, Mr. Barker," said Jones, in the most favorable manner. "We belong to the senior class, and at our last meeting we elected you unanimously a member of the Alpha Zeta Society." "You don't say so!" exclaimed Sam, really astonished. "We have inquired of the faculty concerning your scholarship, and have been told that you are one of the best scholars in the class." "If that's so," thought Sam, "the class don't know much." "There are plenty that know more than me," said Sam, aloud. "All your modesty, Mr. Barker," said Robinson. "We are convinced that you are a first-class man, and will be an acquisition to our society." "What does it all mean?" Sam began to wonder. "We are a committee of the society appointed to initiate you by the usual impressive ceremonies," said Brown. "It is very fortunate we have met with you, for Saturday is our day for initiations." "Is it?" "Yes; have you any particular engagement for the next hour?" "Not as I know of." "Then we will at once proceed to the society room and take you to the initiation. Are you ready?" "I haven't made my will yet," said Sam, humorously. The three sophomores looked at each other doubtfully. Perhaps their intended butt was not as verdant as they supposed.
