"Excellent!" exclaimed the old gentleman, approvingly.  "You have thought out the identical scheme that suggested itself to me, and I hope that by following it you will succeed in laying the fellow by the heels. Speak every craft that you may fall in with, make enquiries whenever you have the chance, and perhaps you may be lucky enough to pick up a slaver or two, and so make the cruise a profitable one in a double sense; for if that surmise of yours should happen to be correct, that this pirate brig is the identical craft that stole the slaves from your prize--the _Dolores_--and afterwards destroyed her, the fellow may have played the trick on other slavers, in which case they will be glad enough to give any information that may lead to his capture.  And now the sooner that you are off the better, for you will have none too much daylight in which to work out clear of the shoals.  So, good-bye, my lad, and good luck to you!  Take care of your ship, your crew, and yourself, and bring the fellow back with you as a prize."
