"Look out!" shouted Rucker. "She's making ready to give us a broadside."

"Lively there, men!" roared Gary, nearly frantic. "Do you want to spend a year or so in a Yankee jail?"

A redoubled roar from the cruiser followed, and a small tempest of iron hurtled around them.

One shot passed through the after hold, terrifying anew the negroes, who yelled fearfully. A rent or two in the sails was all the damage beside, that was inflicted.

Ralph, who was assisting to reeve a new block at the foretop, saw that the fog was almost at hand. But before it came a change of wind; preceding which, as the southeaster died, there were a few moments of calm.

The lull reached the Wanderer first, and the cruiser, swinging to her course, forged so far ahead that, before the schooner could again hoist her foresail, the Adams rounded to, less than half a mile away and presented a frowning row of shotted guns to the slaver's stern. It was a fair raking position.

Rucker threw down his speaking trumpet in despair, though Gary's eyes were fixed keenly upon the advancing fog. A signal for the slaver to lie to was followed by a peremptory shot athwart the schooner's bow.

At the same time a boat was lowered away, filled with armed men, and started towards the Wanderer.

"Heave to, men!" ordered the captain. "But be ready to hoist the fo's'l when I give the word. Down with your helm—down, man!" This to the man at the wheel. "We mustn't give those fellows any cause to suspect us—now."

While the boat approached, it was at times lost in the hollows of the seas, but always rose again nearer than before. Meanwhile the Wanderer lay to, with her mainsail flattened and her topsails aback.
