"Well, this settles the snowball fight for us," put in Stanley, as he looked up and down the road. "The freshies and sophs are clear out of sight. Let us go back to the campus and celebrate our victory;" and then, as Belright Fogg drove away in his cutter, the students walked over the hill in the direction of Brill.

To my old readers the youths already mentioned in these pages will need no special introduction. For the benefit of others, however, let me state that Sam Rover was the youngest of three brothers, Dick being the eldest and fun-loving Tom coming next. They were the sons of one Anderson Rover, a rich widower, and had for years made their home with their Uncle Randolph and their Aunt Martha at a beautiful farm called Valley Brook.

From the farm, and while their father was in Africa, the three Rover boys had been sent by their uncle to school, as related in the first volume of this series, entitled "The Rover Boys at School." This place was called Putnam Hall Military Academy, and there the lads made many friends, and likewise several enemies, and had "the time of their lives," as Tom Rover often expressed it.[*]

[*] For particulars regarding how Putnam Hall Military Academy was organized, and what fine times the cadets there enjoyed even before the Rover boys came on the scene, read "The Putnam Hall Series," six volumes, starting with "The Putnam Hall Cadets."—Publishers.

The first term at school was followed by an exciting trip on the ocean, and then another trip into the jungles of Africa, where the boys went looking for their parent. Then came a trip to the West, followed by some grand times on the Great Lakes and in the Mountains. Then the boys returned to Putnam Hall, to go into an encampment with their fellow-cadets.

This term at Putnam Hall was followed by a never-to-be-forgotten journey on Land and Sea to a far-away island in the Pacific. Then they returned to this country, sailing down the Ohio and Mississippi rivers. After leaving the Father of Waters, they took an outing on the Plains, and then went down into Southern Waters, where they solved the mystery of a deserted steam yacht.

After so many exciting adventures the three brothers had been glad to journey to the home farm for a rest, after which they returned to Putnam Hall, settled down to their studies, and graduated with considerable honor.

"Now for college!" Dick Rover had said. But before setting out for Brill, a fine institution of learning located in the Middle West, the boys had become involved in a search for a fortune left on Treasure Isle.

During their days at Putnam Hall the Rover boys had become well acquainted with Dora Stanhope, who lived near the school with her widowed mother, and also with Nellie and Grace Laning, Dora's two cousins, who resided a short distance farther away. It had not been long before Dick and Dora showed a great liking for each other, and at the same time Tom often paired off with Nellie and Sam was frequently seen in the company of Grace.

A few miles away from Brill College was located Hope Seminary, an institution for girls, and when the Rover boys went to Brill, Dora, Nellie and Grace went to Hope; so that the young folks met almost as often as before.
