“But they might have had to catch a ball any moment.”

“Nonsense!” exclaimed the professor. “It is an idle frivolous amusement, and I regret very much that you wasted your valuable time over it. After supper I want to hear you read some Virgil, and also do some problems in geometry. I was instructed by your father to see that your education was not neglected, and I must do my duty, no matter how disagreeable it is.”

Jack sighed. He had studied hard in class that day, and now to be made to put in the evening over his books he thought was very unfair.

But there was no escape from the professor, and the boy had to put in two hours at his Latin and mathematics, which studies, though they undoubtedly did him good, were very distasteful to him.

“You are making scarcely any progress,” said the professor, when Jack had failed to properly answer several of his questions. “I want you to come home early from school to-morrow afternoon, and I will give you my undivided attention until bedtime. I am determined that you shall learn.”

Jack said nothing, but he did not think it would be wise to go off playing ball the next afternoon, though the boys urged him strongly.

“Why don’t you write and tell your dad how mean old Klopper is treating you?” suggested Tom, when Jack explained the reason for going straight home from his classes.

“I would if I knew how to reach him. But I don’t know where he is,” and Jack sighed, for he was becoming more and more alarmed at the long delay in hearing from his father.

But Jack was destined to do no studying that afternoon under the watchful eye of Professor Klopper. He had no sooner entered the house than he was made aware that something unusual had happened.

“My brother is waiting for you in the library,” said Miss Klopper, and Jack noticed that she was excited over something.
