All of the Rover boys gazed eagerly at what was before them. They saw a large stone building, shaped almost in the form of a cross, the upper portion facing the river. It was three stories in height and contained not only the classrooms and mess hall of the institution, but also the dormitories for the boys. To one side was a small brick building which at one time had evidently been a private dwelling. This was now occupied by Colonel Colby and his family and the various professors. On the opposite side was a long, low, wooden building.

"That's our gym," explained Fatty. "You can go in there any time you want to, do a turn on the bars, and break your neck."

Down at the water's edge were several small buildings which, Spouter explained, were used for storing the boats belonging to the Hall and also as bathhouses. Behind the Hall were a stable and a barn, and also a garage. And still farther back were a vegetable garden and some farm fields, for Colonel Colby believed in raising as much stuff for the Hall table as possible.

"That's the Rick Rack River," explained Spouter, as they passed the stream. "We've some dandy times there swimming and boating."

"Don't you have skating in the winter?" queried Andy.

"Sure! And we have some great races, too."

In another moment the auto-stage drew up to the front door of Colby Hall, and one after another the boys and Captain Dale and the other teacher alighted.

"You new pupils may as well follow me right to the office," said the captain. "You can leave your suitcases in the hallway until you have been assigned to your rooms."

He led the way, and they followed through a large reception room and into an elegantly appointed office where Colonel Colby sat at a mahogany desk, writing.

"Some new pupils, Colonel Colby," announced the captain, and at once the colonel arose.
