Matterson and Gleazen faced about, as quickly as weasels on a stone wall, and Gideon North was not much behind them.

"Where away?"

"Off the larboard bow!"

"What do you make her out?" Captain North demanded.

"As yet, sir, she's too far off to be seen clearly."

I had known that we were sailing dangerous seas, but nothing else had so vividly brought our dangers home to me as did the scene of desperate activity that now ensued. Hoarse orders went booming up and down the decks. Men sprang to braces and halyards. For a moment the foresail, newly let fall, roared in the wind, then, clapping like thunder, it filled, as the men tailed on tack and sheet, and catching the wind, stiffened like iron. Wearing ship, we set every stitch of our canvas, and with a breeze that drove us like a greyhound through the long, swiftly running seas, went lasking up the coast of Africa, as, intently training glasses across the taffrail, we waited to see more of the strange vessel.

Notwithstanding our feverish efforts to elude her, she had drawn slowly nearer, and we made out that she was a schooner and as fleet as a bird. For a time there was talk of the armed schooner Shark, which our own government was reported to have sent out to cruise for slavers.

It was with grim interest that we watched her every manœœuvre. Our men forward would constantly turn their heads to study her more closely, and those of us aft kept our eyes fixed upon her. Swift as was the Adventure, it was plain from the first that the schooner was outsailing her in a way that seemed almost to savor of wizardry.

"I swear I can see the hangman's knot in her halyard," Gleazen cried, and roundly braced his oath. "Never before did I feel such an itching on my neck."
