"He jumped off the dock and got your boat, which went adrift right in the course of that steamer," explained a 'longshoreman who had listened to the conversation and who had seen what Nat did. "Plucky thing it was, too. If it hadn't been for him you wouldn't have any boat now."

"Is that so? I didn't understand. I thought he was trying to steal my boat."

"Steal your boat? Say, you don't belong around here, do you?"

"No. My father is the owner of a small steam yacht, and I am taking a trip with him. This is the first time I was ever in Chicago. The yacht is tied out there, beyond some other vessels, and I took this boat and came ashore a while ago to see the sights. When I came back I saw that boy in my boat."

"Humph!" murmured the 'longshoreman as he turned away. "You want to take a few lessons in tying ropes. That boy did you a good service."

"I see he did, and I'm sorry I spoke the way I did. I'll give him a reward."

By this time Nat was up on the pier from which he had jumped. He found his clothes, and put them on over his wet undergarments. The day was hot, and he knew the latter would soon dry.

Besides, he was used to being wet half the time, as he and other lads of his acquaintance frequently dived off the stringpiece and swam around in the lake. So when the owner of the rescued rowboat looked for the boy he could not see him. But he determined to make up for his unintentional rudeness, and so went after Nat.

He found the boy with a number of others crowded about the entrance to the freight office.

"May I speak to you a few moments?" asked the young man.
