package contained food, Bob could not understand. But had the boy been as keen an observer as the stranger, he would have noticed that the paper on one end of the box was saturated with grease, causing the obvious inference that some sort of food was wrapped up inside.
"I don't like to take your grub for nothing, son," returned the other, "but I sure am hungry. I have always made it a rule never to accept anything from any one without giving something in return. So I tell you what I'll do. If you're sure you won't accept any money, and will give me a bite, when the train stops for dinner, I'll pay for whatever you want to eat."
"That seems fair," returned Bob, "but I should be just as willing to give you some, even if you didn't return it."
While Bob had been speaking, he had picked up the box, broken the string, unwrapped the paper and opened it, after which he held it out to the stranger, saying:
"Help yourself."
To Bob's surprise, the man accepted the invitation literally—and took the whole box, which he rested on his knee. Though it contained cake and pie, hard-boiled eggs, and several sandwiches, the stranger exercised no choice of selection, but began at one end of the box and ate everything just as it came.
