"Oh!"

An interjection can sometimes express more than words. My sweetheart's left me wondering just what she meant. There was amusement in it, but there was, too, a demure suppression to which I had not the key.

She, too, I judged, had known a few love episodes in her life. Perhaps she had been engaged before, as is sometimes the custom among Southern girls. The thought gave me a queer little stab of pain.

Yeager came out of the deck pavilion as we passed.

"I say, let's have some music, good people."

I looked at my watch.

"My turn at the wheel. Maybe Blythe will join you."

He did. From the pilot-house I could hear his clear tenor and Evelyn's sweet soprano filling the night with music. Presently they drifted into patriotic songs, in which Tom came out strong if not melodious. But when the piano sounded the notes of "Dixie" Evelyn's voice rose alone, clear and full-throated as that of a lark.

After being relieved by Alderson I turned in and slept round the clock. The tune of drumming engines was in my ears when I woke.

"Sam is making her walk," I thought, and when I reached the deck I learned that we had entered the Gulf of Panama. A long, low line showed dimly in the foggy distance to the left. We were running parallel with it, Prieto Point directly in front of us.
