Then had followed a trip out West, and another on the Great Lakes.

Later the youths had camped out in the mountains during the winter, shooting quite some game.
Then they had returned to school, to go into camp during the summer with the other cadets.
The boys by this time thought their adventures at an end, but more were soon to follow.

There came a long trip on land and sea, and then a voyage down the Ohio River, and soon after this the Rovers found themselves on the plains, where they had some adventures far out of the ordinary.

From the plains they went further south, and in southern waters--the same being the Gulf of Mexico--they solved the mystery of the deserted steam yacht.
"Now back to the farm for me!" Sam had said at this time, and all were glad to go back, and also to return to Putnam Hall, from which seat of learning they presently graduated with honors.

Then Mr.Anderson Rover got word of a valuable treasure, and he and the boys, with a number of their friends, went to Treasure Isle in search of it.
