Have you any knowledge of vessels?

None, except what I have learned from the books.

Put the questions to the boy directly, suggested Webb.

That would do if I was examining him for Sailing Master, replied the Captain, but it is not expected that the young man has studied or knows anything about navigation.

I am willing to be examined on that point, rejoined Walter.

The Captain was surprised at the cool confidence of the boy, but proceeded with his examination. He soon found that theoretically, the young man was perfect. He also learned that book learning was not to be despised, for Walter was not only master of the principles of navigation, but could locate almost all the continents, seas and shoals of the world. He could name the different parts of a ship, and the rigging employed in sailing it.

That will do for the present, young man. You can retire, and I will talk over the matter with Mr. Webb.

Walter left the room.

Mr. Webb, this young man is a prodigy. When, how and where did he acquire this knowledge? I never understood that you were a navigator.

But you forget, Captain, that I am a surveyor and civil engineer, and that before I could trust him to do my work, I had to know that he understood the principles, and from surveying to navigation, there is but one step, and that step he has taken.
