“Freight train ahead, off the track,” announced Tom.  “We ran into the last car.”

“Let us go up front and see how bad it is,” returned Dick.  “Maybe this will tie us up here for hours.”

“Oh, I hope not,” cried Sam.  “I want to get to the college just as soon as possible.  I’m dying to know what it’s like.”

“We can be thankful we were not hurt, Sam,” said his older brother.  “If our engineer hadn’t stopped the train as he did we might have had a fearful smashup.”

“I know it,” answered Sam soberly, and then the boys walked forward to learn the full extent of the damage done and what prospects there were of continuing their journey.

To my old readers the lads just mentioned will need no special introduction, but for the benefit of those who have not read the previous volumes in this “Rover Boys Series” let me state that the brothers were three in number, Dick being the oldest, fun-loving Tom coming next and Sam the youngest.  They were the sons of one Anderson Rover, a rich widower, and when at home lived with their father and an aunt and an uncle on a beautiful farm called Valley Brook.

From the farm, and while their father was in Africa, the boys had been sent by their Uncle Randolph to school, as related in the first book of the series, called “The Rover Boys at School.”  At this place, called Putnam Hall, they made many friends and also a few enemies and had “the time of their lives,” as Tom often expressed it.

A term at school had been followed by a short trip on the ocean, and then the boys, in company with their uncle, went to the jungles of Africa to rescue Mr. Rover, who was a captive of a savage tribe of natives.  After that came trips out West, and to the Great Lakes, and to the mountains, and, returning to school, the lads went into camp with the other cadets.  Then they took another long trip on land and sea and led a Crusoe-like life on an island of the Pacific Ocean.

“I think we’d better settle down now,” said Dick on returning home from being cast away, but this was not to be.  They took a house-boat trip down the Ohio and the Mississippi rivers, had a number of adventures on the plains and then found themselves in southern waters, where they solved the mystery of a deserted steam yacht.

They returned to the farm and to Putnam Hall, and for a time matters went along quietly.  On account of attending to some business for his father, Dick had fallen somewhat behind in his studies, and Tom and Sam did their best to catch up to him, and, as a consequence, all three of the youths graduated from Putnam Hall at the same time.

“And now for college!” Sam had said, and all were anxious to know where their parent intended to send them next But instead of settling this question Mr. Rover came forward with a proposition that was as novel as it was inviting.  This was nothing less than to visit a spot in the West Indies, known as Treasure Isle, and made a hunt for a large treasure secreted there during a rebellion in one of the Central American countries.
