“Payin’ dues,” I says, quick.

“Havin’ somethin’ to eat,” Binney guessed.

“Naw,” Mark grunts, contemptuous. “The main thing about a secret society is the s-s-secret.”

We could see in a minute that he was right about that.

“So,” he went on, “if we’re goin’ to have a secret society the first thing is to git a s-s-secret to have.”

“I don’t know no secret,” Binney said, shaking his head hard.

“Nor me,” said Plunk.

I thought a minute, because I knew a couple of secrets, but they were secrets I didn’t calculate to tell anybody, least of all Mark and Plunk and Binney; so I just shook my head, too.

“We’ll make a secret,” Mark told us.

“How?” I wanted to know, because I didn’t see how you could go to work to make a secret, but I might have known Mark would find a way.
