This announcement, though we knew not what it referred to, had an evident effect on our captors, who were probably part of a slaver's crew; for they all scrambled up to the opening in the rocks to look out.

"Now, now is the time to slip our cables and run. Follow me!" said Tom Lambourne, in a hoarse but determined whisper, as he sprang forward—snatched up two of the muskets, and rushed across the plank, tripping as lightly as he would have done along a boom or yard, though it crossed a gulf so terrible.

Less steadily, but not less rapidly, you may be assured—yet with a frozen heart—I followed him, and his hard tarry hand was ready to grasp mine and drag me forward into safety, while with a violent kick he tossed the plank away, and surging down it went, into the black gulf we had crossed.

It vanished in a moment, and no sound ever ascended, for it seemed to have fallen into a pit that was dark as it was bottomless!

"Take this musket, and see that you can use it, sir," said Tom, as an emotion of bravado seized him. "And so, you Spanish greenhorns," he shouted, "you thought to sell me for a nigger to the Yankees, did you? Whoop—hurrah!"

A volley of Spanish oaths followed this rash outburst, which drew their attention at once upon us. Some rushed to the dark brink and paused, I suppose, for neither Tom nor I could see distinctly, as there was a double explosion which filled the cavern with echoes like those of rolling thunder, and a momentary glare of smoky light, while two musket-balls whistled past us; and I felt one like a hot cinder, as it grazed my left ear. Then came an Albacete knife, which was hurled by no erring hand, for it wounded Tom's right knee.

"Give them a shot, Mr. Rodney," said he, furiously; "I'll reserve my fire for the sentry,—and here he is already!"

And just as the eighth fellow, who was on the watch, alarmed by the firing, came rushing in with his piece at full cock, Tom fired at him.

"Saints and angels!" yelled the Spaniard, as he bounded into the air, and then fell flat on his face, where he lay beating the earth with his feet and hands.

"Fire! fire! Master Rodney, and then run for it, before they can reload," cried Tom, who saw that I was irresolute; "give 'em a stern chaser!"
