Two of the seniors presently came in. They settled with pennies. Then came Laura Bentley and Belle Meade. Their pennies were laid on the principal's desk. "Why, all pennies, so far!" exclaimed Mr. Cantwell. "I trust not many will bring coins of such low denomination." A look of bland innocence rested on Laura's face. "Why, sir," she remarked, "you asked us, Friday, to bring pennies. "Did I?" demanded the principal, a look of astonishment on his face. "Why, yes, sir," Belle Meade rattled on. "Don't you remember? You laughed, Mr. Cantwell, and asked each one of us to bring fifteen pennies to-day." "I had forgotten that, Miss Meade," returned the principal. Then, as the sophomore young ladies turned away, a look of suspicion began to settle on the principal's face. Nor did that look lessen any when the next six students to come in each carried pennies to the desk. Twenty more brought pennies. By this time there was a stern look on the principal's white face. During the next few minutes after that only two or three came in, for Dick had thought of a new aspect to the joke. He had sent messengers scurrying out through the street approaches with this message: "We're not required to be in the assembly room until eight o'clock. Let's all wait until two minutes of eight---then go in a throng." So the principal had a chance to catch up with his counting as the minutes passed. So busy was he, however, that it didn't quite occur to him to wonder why so few of the student body had as yet come in. Then, at 7.58, a resounding tread was heard on the stairs leading up from the basement locker rooms. Some two hundred boys and girls were coming up in two separate throngs. They were still coming when the assembly bell rang. As fast as any entered they made their way, with solemn faces, to the desk on the platform. As Mr. Cantwell had feared, the pennies still continued to pour in upon him. Suddenly the principal struck his desk sharply with a ruler, then leaped to his feet. His face was whiter than ever. It was plain that the man was struggling to control himself against an outburst of wrath. He even forced a smile to his face a sort of smile that had no mirth in it. "Young ladies and young gentlemen," Mr. Cantwell rasped out, sharply, "some of you have seen fit to plan a joke against me, and to carry it out most audaciously. It's a good joke, and I admit that it's on me. But it has been carried far enough. If you please---_no more pennies_!" "But pennies are all I happen to have, sir," protested Dave Darrin, stepping forward. "Don't you want me to pay you for the music, sir?" "Oh, well," replied the principal, with a sigh, "I'll take 'em, then."
