you can't tell how long a war like this will last. For all you
know the Germans may come right over here."

"I don't think they'll do that. They'll have their hands full fighting
in Europe."

"Well, they've sent their submarines over here already."

"I know that. But I don't think they've got enough submarines to
transport an army that way."

Since coming to Colby Hall the Rover boys had occupied four very
pleasant rooms on the second floor in a wing of the great building.
But instead of using the four rooms for bedrooms, the twins slept
together and all used one of the extra rooms, No. 20, for a
sitting-room.

"You fellows have got to hurry up or you'll be late for roll call!"
cried Randy, when he entered.

"Oh, I think they'll give us a little leeway on account of all the

cadets fell to with vigor. There was a constant clatter of forks and
knives, mingled with a flow of lively conversation, carried on,
however, in rather a subdued tone, for boisterousness of any sort in
the mess hall was against regulations. After each lad finished he
excused himself and left the hall, and soon all of them had scattered
in various directions.

"Bonfires to-night!" announced Andy gaily, as he turned a handspring
on the campus.

"I think we ought to have some sort of feast," said Fred.

"Great Caesar, Fred! didn't you get enough to eat at supper?" queried
Jack.

"Oh, you know what I mean--a little something to eat just befo
