"And George Granbury is going up to the Thousand Islands with his folks," put in Tom. "We might ask Songbird Powell," came from Dick. "I don't believe he is going anywhere in particular." "Yes, we ought to have him by all means, and Hans Mueller, too. They would be the life of the party." "I should like to have Fred Garrison along," said Sam. "He is always good company. We can--" Sam broke off short as the roll of a drum was heard on the parade ground outside the tent. "Dress parade, for the last time!" cried Dick Rover. "Come, get out and be quick about it!" And as captain of Company A he caught up his sword and buckled it on in a hurry, while Tom, as a lieutenant of the same command, did likewise. When they came out on the parade ground of the encampment they found the cadets of Putnam Hall hurrying to the spot from all directions. It was a perfect day, this fifth of July, with the sun shining brightly and a gentle breeze blowing. The camp was as clean as a whistle, and from the tall flagstaff in front of the grounds Old Glory flapped bravely out on the air. To those who have read "The Rover Boys at School," and other volumes in this series, Dick, Tom, and Sam need no special introduction. When at home they lived with their father and their aunt and uncle at Valley Brook farm, pleasantly located in the heart of New York State. From this farm they had been sent by their uncle Randolph to Putnam Hall military academy, presided over by Captain Victor Putnam, to whom they became warmly attached. At the academy they made many firm friends, some of whom will be introduced in the pages which follow, and also several enemies, among them Dan Baxter, the offspring of a criminal named Arnold Baxter, who, after suffering for his crimes by various terms of imprisonment, was now very sick and inclined to turn over a new leaf and become a better man. A term at school had been followed by a remarkable chase on the ocean, and then a journey to the jungles of Africa, in a hunt after Anderson Rover, the boys' father, who was missing. Then had come a trip to a gold mine in the West, followed by some exciting adventures on the Great Lakes. On an island in one of the lakes they unearthed a document relating to a treasure hidden in the Adirondack Mountains, and next made their way to that locality, in midwinter, and obtained a box containing gold, silver, and precious stones, much to their satisfaction.
