Before Sam reached Harvard Square he caught sight of the college yard and the numerous buildings of brick and stone which had been erected within it for the accommodations of the students.

"It's a pretty big place," thought Sam. His ideas of a college were very vague. He had fancied that it consisted of one large brick building, like the New York public schools.

"I wonder what they want of so many buildings, anyway?" said Sam to himself. "There must be a lot of students."

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?"
