"Is there any boy here who knows anything at all about my collection?" demanded the doctor, sharply. "If so, let him stand up."
There was a pause, but nobody arose. The master of Oak Hall drew a long breath.
"If this is a joke, I want the collection returned by to-morrow morning," he went on. "If this is not done, and I learn who is guilty, I shall expel that student from this school."
He then passed on to the next classroom, and so on through the whole academy. But nothing was learned concerning the missing stamp collection, and the end of the inquiry left the worthy doctor much perplexed and worried.
"That is too bad," was Dave's comment, after school was dismissed. "That was a nice collection. I'd hate to have it mussed up, if it was mine."
"The fellow who played that joke went too far," said the senator's son. "He ought to put the collection back at once."
The matter was talked over by all the students for several days. In the meantime Doctor Clay went on a vigorous hunt for the stamp collection, but without success.
"Do you think it possible that somebody stole that collection?" questioned Dave of Phil one afternoon, as he and his chum strolled in the direction of Farmer Cadmore's place, to see if they could learn anything about the ram.
