"There is the bridge!" burst out another, pointing ahead. "Oh,
Heavens, boys, we are lost!"

All strained their eyes ahead to see what he meant, and then every face grew pale. The bridge was torn up completely, not a single plank of the flooring remained.

CHAPTER II

SOMETHING ABOUT THE ROVER BOYS

The Rover boys were three in number, Dick being the oldest, Tom coming next, and Sam the youngest. In their younger days they had resided with their parents in New York, but after the death of their mother and the disappearance of their father they had gone to live with their uncle, Randolph Rover, and their Aunt Martha, on a farm called Valley Brook, near the village of Dexter Corners, on the Swift River.

Those who have read the previous volumes of this series, entitled respectively, "The Rover Boys at School." "The Rover Boys on the Ocean," and "The Rover Boys in the jungle," know that our three heroes had already passed through many trying experiences and thrilling adventures. From home they had been sent to Putnam Hall, a military academy of high standing, and here they had made many friends, including those already mentioned, and several enemies, among the latter being one Dan Baxter, who was known as the school bully, and John Fenwick, better known as Mumps, the bully's toady. They had also made a bitter enemy of Josiah Crabtree, the headmaster of the Hall.

But since those first days at the school many things had happened and many changes had occurred. It was discovered that Dan Baxter was the son of one Arnold Baxter, a rascal who had, years before, tried to swindle the Rover boys' father out of some valuable mining property in the West, and that the son was little better than his parent. Dan had left the school in a hurry, and soon after this his father had been arrested in Albany for a daring office robbery, and was now in jail in consequence.

The disappearance of Dan, and Josiah Crabtree's yearning for wealth, had led to further complications. Near Putnam Hall resides the widow Stanhope and her pretty daughter Dora, and Crabtree, who exerted a sort of hypnotic power over the widow, tried to get the lady to marry him, so that he might obtain the fortune she held in trust for her daughter. But how the Rover boys fooled the grasping teacher, and how Dora was saved from the plot Crabtree and Dan Baxter hatched up against her, has already been told in "The Rover Boys on the Ocean."

Anderson Rover had gone to Africa to locate certain mines in that country, and when many years passed and no word came from him the three boys grew worried and wanted to go in search of him. At last came a strange letter written by a sea captain, containing some important information, and acting on this the Rover boys, accompanied by their Uncle Randolph, set out for the heart of the Dark Continent to find the long-lost. On the way they fell in with one Alexander Pop, who had formerly been a waiter at Putnam Hall, who proved a valuable friend when it came to dealing with men of his own ebony hue. In this hunt they likewise ran across Josiah Crabtree, who was out with an exploring party from Yale, and with Dan Baxter, and both of these rascals tried to do them much harm. But the schemes of the rascals fell through, and Crabtree only escaped after a severe whipping at the hands of Dick Rover, while Dan Baxter fared little better. Soon after this Mr. Rover was found, as a prisoner of a savage African tribe, and rescued, and then the entire party returned to the United States. Alexander Pop remained in the employ of the two elder Rovers, and the three boys returned to finish the term at Putnam Hall.

These are a few of the things that had happened. But there were countless others, which space will not permit being mentioned here. There had been many contests, in baseball, football, and other sports, and jokes that seemed to have no end, and there had also been a disastrous fire, which none of the Putnam Hall cadets were likely ever to forget—a fire as thrilling as the scene now being enacted on the road. But I am afraid I have already left the boys in the runaway stage too long, so we will return to them without further delay.
