How the man had been able to divine that his 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.

Naturally Bob had supposed that the man would eat possibly only a couple of eggs and one or two sandwiches, with perhaps even a piece of cake or a piece of pie. But as he saw one piece of food disappearing after another, and remembered that the stranger had asked only for a bite, he wondered what he would require to make a full meal.

As the last piece of food was devoured, the man reached down, put the cover on the box, folded the paper, wrapped up the box and set it on the floor, wiping his mouth with the back of his hand, then exclaimed:

"My, but that went to the right spot! I sure was hungry."

"Yes, I guess you were," assented Bob, a bit ruefully, for he had expected to have at least a portion of the food, put up for him by the kind waitress, to eat during the day.
