“How did it happen, Andy?” asked Jerry, as he ran along.

“Yes, tell us more about it,” urged Bob.

“Is it the big reservoir dam that’s broken?” asked Ned. “If it is, there’ll be a lot of damage, and yet I don’t hear any great excitement,” and he paused a moment to listen if he could catch the roar of rushing waters. But there came no unusual sound from the direction of the river which bordered the town of Cresville, where the boys lived.

“I don’t know—didn’t see it!” panted Andy. “Old Pete Bumps told me—said it was the dam—terrible—everything washed away—come on—wow!”

“Oh, if it was old Pete Bumps, our hired man, who told you, it can’t be so bad,” returned Bob Baker. “Pete always makes a big fuss over everything. Let’s take it easy, fellows.”

“You can’t tell,” interposed Jerry. “Something must have happened. I see a lot of fellows running toward the river,” and he nodded toward a side street, through which could be had a glimpse of a thoroughfare parallel to the one on which our friends were, both extending to the stream. “Come on,” finished the tall lad. “We’ll see what it is,” and he increased his pace, his companions doing likewise.

While I have just a few moments before the boys reach the river, and in which time they are doing nothing but running, and wondering what has happened, I will take the opportunity to tell you something about the chums, and the various books, previous to this one, in which they have figured.

The first volume of the series entitled, “The Motor Boys,” told how the chums got together, and entered a bicycle race. Later on they got motor-cycles, and then an automobile in which they had many adventures. They took a long trip overland, got possession of a gold mine, and later went to Mexico, where they were in great danger. But they managed to escape, and, on a long trip across the plains they rescued the hermit of Lost Lake.

After these adventures, our heroes decided that motor boating would suit them, and they succeeded in getting a fine craft. In the volume named, “The Motor Boys Afloat,” is told how the lads cruised in the Dartaway, and succeeded in finding the robbers who had broken into Mr. Slade’s department store.

The lads liked motor boating so well that they took a cruise on the Atlantic, during which they solved the mystery of the lighthouse, and, later on, they went to the strange waters of the Florida Everglades.
