"Well, we had a dandy time, in spite of the breakdown," remarked the young major.

"No. Why?"
"Somebody was mean enough to tamper with our bicycles," answered the young major, and gave a few particulars.
"Oh, you can bet it was the Ritter crowd, or Ritter alone," said Stuffer, quickly. "It would be just like them to do their best to spoil your fun."
