"Oh, I'm going to cram my head full of learning this trip," answered
Tom with a grin.
"Take care of yourselves and don't get sick," was Aunt Martha's warning. "If you do, get a doctor right away." And then she gave each of the boys a warm, motherly kiss and a hug. She thought the lads the very best in all this wide world.
The train came and the boys were off. After a two hours' ride they had to change to the main line and got into the parlor car already mentioned. Then they had dinner in the diner and went back to the other car to read and to look at the scenery. Thus several hours slipped by, when of a sudden came the jar and shock that told them something out of the ordinary had happened.
CHAPTER II
AT THE SANDERSON HOUSE
When the Rover boys reached the head of the train they found an excited crowd beginning to collect. The locomotive of the express had cut into the last freight car a distance of several feet, smashing a number of boxes and barrels and likewise the headlight of the engine. Nobody had been hurt, for which everybody was thankful. But the engineer of the express was very angry.
"Why didn't you send a man back with a flag or put a torpedo on the track?" he demanded of the freight train conductor.
"Did send a man back," was the answer, "but he didn't go back far enough—hadn't time. This happened only a few minutes ago."
"You can't expect me to stop in a hundred feet," growled the engineer.
As a matter of fact he had not stopped in many times that distance.
"Well, I did what I could," grumbled the freight conductor.
