“Now, lad,” said he, when it was completed, “you just turn in and take a good sleep and I’ll stand watch.”

As Nat was feeling drowsy again, doubtless owing to the far-reaching influence of Israel Harley’s opiate, he was nothing loath to accept this proposition, and turned in and was speedily in the land of dreams. When the captain awakened him he felt that the last traces of the drug had vanished, and his senses were as clear as a bell. The sun was high and the sea smooth and sparkling. Nat had some coffee and rolls and then joined the captain on deck. He gazed anxiously toward Santa Barbara, eager to catch the first glimpse of the Nomad.

Near by the Lightship several triangular fins were cruising about.

My first mate proposed to me that we should take a swim. Now, although I’m minus one of my spars, I’m a right smart swimmer, and I agreed.

“We had a fine time sporting round thar in the cool water, but suddenly somebody on deck hollers, ‘Sharks!’

“Now that’s a hail you want to act quick on, and you take my alfired-davy on it that we made good time getting back to the ship’s side. But just as we reached it, what d’ye suppose?”
