“We have learned some things, but I fear there are still many things for us to learn,” replied Dan, with a half smile.

“Just so. You have learned to make all the various knots that a sailor is supposed to be familiar with?”

“Yes, sir,” answered the boys in chorus.

“And belay a fall?”

“Yes, sir; we know how to take a turn on a cleat with a rope.

“Very good. Hickey, my lad, now that you know how to belay a fall, I will ask if you can pass a stopper?”

A blank expression appeared on Sam’s face, while a twinkle showed in the eyes of the boatswain’s mate.

“I—I don’t know, sir. If the stopper were good to eat I don’t think I should pass it unless I were walking in my sleep.”

The boatswain’s mate leaned back and laughed uproariously.

“Passing a stopper, my lad, means to wrap a rope about a fall while another belays it. There are a lot of these sea terms that you will learn as you go along. I see you have been assigned to the deck. What branch of the service would you prefer to be in, or haven’t you thought about the matter seriously?”
