rowed it out into the middle of the river.

"Now I guess we can talk without being overheard," said Bart, when they
were well out from shore, and rowing up stream. "What's up, Sandy?"

"The Upside Down boys have a plot on foot to spoil the dinner."

"What dinner?" asked Bart, wishing to see just how much Sandy knew.

"Oh, the dinner the baseball nine is going to have. It's all over. Some
one must have talked. I heard of it late Saturday night, but it wasn't
until last night that I heard of the conspiracy."

"What are they going to do?" asked Bart.

"That I can't tell," Sandy replied. "You know that, though I'm in the
first-year class, I don't belong to the society. I didn't join. One of
the members thought I was in and before he knew what he was doing he had
blurted out something about their going to take the dinner stuff from
Fenn's barn. Then he found out I wasn't a member, and a lot of 'em got
around me and made all sorts of threats if I told. I wouldn't promise not
to, but I can't find out any more, except that they're going to make a
raid on the place just before it's time for the dinner."

"How many?" asked Bart.

"About fifty of 'em."

"Whew!" exclaimed the captain of the nine.
