"Simply that they'd like to see you come to the hop and have nobody to dance with—for no girl will dance with a plebe, you know, I don't care who he is—and so have to go home feeling pretty cheap. Then you'd be the laughingstock of the corps, as the plebe who wanted to dance at the hop."

It was Chauncey's turn to be thoughtful then. And to his credit be it said that he recognized the truth there was in Mark's explanation of that surprising card. For Chauncey was no fool, even if he was dudish and aristocratic.

"I'm afraid that's it," said he. "I'm deuced glad I thought of asking you, Mark, ye know. I'll not go to-night. And we'll let the matter drop, bah Jove."

"Let it drop!" echoed Mark; and then he added, with emphasis, "Not much!"

"What'll ye do?"

"Do? What's the use of having a secret society for the purpose of avenging insults, if you don't avenge 'em? And don't you call it an insult that the yearlings should suppose us big enough fools to take that bait and go to their old hop?"

"It was rather insulting," admitted Chauncey.

"It was," said Mark. "And what's more, I move that we retaliate this very day. Let's go up and find the rest of the Seven, and by Jingo, perhaps we'll bust up their plaguey old hop!"

With which words Mark slammed his book to and arose to his feet and set out in a hurry for camp.

They entered Camp McPherson and hurried up the A Company "street" to their own tent. They entered without ceremony, and Mark scarcely waited to greet the rest before he plunged right into the subject in hand.
