"Then come into the pilot-house with me, and I will explain a few more things to you. I think you have a natural talent for this sort of life, and I like to show to boys, who appreciate it, the different things there are to learn. For there are a good many of them, and it's going to take you a long time."

Nat had no false notions about learning to be a pilot. He knew it would take him several years to be a capable one, but he determined to get a good ground work or the higher branches of it, and so he listened carefully to all that Mr. Weatherby told him.

He learned how to read the compass and how to give the proper signals to the engineer.

For a number of days he spent several hours out of the twenty-four in the pilot-house with Mr. Weatherby. He got an understanding of the charts of the lake, of the various signals used by other ships, to indicate the course they were on, and he learned to know the meaning of the shore signal lights, and the location of the lighthouses that marked the dangerous rocks and shoals.

"You're doing very well," Mr. Weatherby said to him one day. "Much better than I expected. Some time I'll let you try your hand at steering a bit."

"Oh, that will be fine!" exclaimed Nat, but he little knew what was going to result from it.

CHAPTER IX
A NARROW ESCAPE

Though he was much interested in beginning on his long-cherished plan of becoming a pilot, Nat did not lose sight of the fact that there was some mystery concerning his father, in which the mate had a part. He had not given up his belief that Mr. Bumstead had Mr. Morton's wallet, in spite of the mate's denials. But Nat saw no way by which he could get at the bottom of the matter.

"I guess I'll just have to wait until chance puts something in my way," he said to himself. "At the same time I've got to be on the watch against him. I believe he, or some one of his cronies, pushed that bale on me. I don't suppose it would have killed me if it had fallen flat on me, instead of only partly, but it looks as if he wanted to drive me off of this ship. But I'll not go! I'll stay and see what comes of it."
