“Will you lend me your hat, Mr. Clinton?” he asked presently, of the dude.

“Certainly, professor,” drawled the young man.

The professor took it, and tapped it.

“Are you sure there is nothing in it?” he asked.

“I am sure of it. Really, I don’t carry things in my hat, don’t you know.”

“What do you say to this, then?” and Professor Hemenway drew out of the hat half a dozen onions, a couple of potatoes, and a ship biscuit.

“My dear sir, I think you are mistaken,” he said. “I see you carry your lunch in your hat.”

All present laughed at the horrified face of the dude.

“On my honor, I don’t know how those horrid things came in my hat,” he stammered.

“Are you fond of onions, Mr. Clinton?” asked Harry.
