“What’s the matter?” asked Bob, of a boy running past the house.

“Railroad collision! Lots killed! Down near the cut crossing!” the lad exclaimed.

“Come on!” Jerry shouted. “Let’s go!”


[CHAPTER II]
THE RAILROAD WRECK

The boys grabbed up their hats, raced down the steps, and along the street in the direction of the railroad. While they are on their way, the reader may care to ascertain a little more about the three chums, and something of their doings, which have been set forth in previous volumes of this series.

Jerry Hopkins was the son of a well-to-do widow, Bob Baker the offspring of a rich banker, while Ned Slade’s father owned a large department store.

The first volume of the series, entitled “The Motor Boys,” told how the lads took part in bicycle races, and how one of them won a fine motor cycle. They incurred the enmity of Noddy Nixon, a town bully, and his crony, Bill Berry. The chums had many experiences on their motor cycles, and in a race they won a fine touring automobile. Their adventures, and exciting ones they were, which followed the acquisition of the car, were told of in the second volume, “The Motor Boys Overland.” They went west to search for an old mine, of which a prospector they had befriended had told them. They found the claim, with the aid of Jim Nestor, though they had a close race with Noddy Nixon and Bill Berry to get formal possession.

On their western trip the boys had become acquainted with an old man, Professor Uriah Snodgrass, a naturalist, and he told them of an ancient buried city in Old Mexico. The boys resolved to search for it, and how they succeeded was set forth in the third volume, “The Motor Boys in Mexico.” They had several fights with the Mexicans and Bob was kidnapped, but escaped. The ancient city was found, very unexpectedly, as the auto sunk down through a concealed road and coursed along an underground passage. There many strange things occurred, including the discovery of the disappearing reservoir, and a valuable box of jewels.
