Captain Horn had frequently heard of them in the past year or two, and it was generally supposed that they had some sort of rendezvous or refuge on this coast, but there had been no effort made to seek them out.
He had frequently heard of crimes committed by them at points along the coast, which showed that they had in their possession some sort of vessel.

At one time, when he had stopped at Lima, he had heard that there was talk of the government's sending out a police or military expedition against these outlaws, but he had never known of anything of the sort being done.
Everything that, from time to time, had been told Captain Horn about the Rackbirds showed that they surpassed in cruelty and utter vileness any other bandits, or even savages, of whom he had ever heard.

Among other news, he had been told that the former leader of the band, which was supposed to be composed of men of many nationalities, was a French Canadian, who had been murdered by his companions because, while robbing a plantation in the interior,--they had frequently been known to cross the desert and the mountains,--he had forborne to kill an old man because as the trembling graybeard looked up at him he had reminded him of his father.

Some of the leading demons of the band determined that they could not have such a fool as this for their leader, and he was killed while asleep.
Now the band was headed by a Spaniard, whose fiendishness was of a sufficiently high order to satisfy the most exacting of his fellows.
These and other bits of news about the Rackbirds had been told by one of the band who had escaped to Panama after the murder of the captain, fearing that his own talents for baseness did not reach the average necessary for a Rackbird.
When he had made his landing from the wreck, Captain Horn never gave a thought to the existence of this band of scoundrels.

In fact, he had supposed, when he had thought of the matter, that their rendezvous must be far south of this point.
But now, standing on that shelf of rock, with his eyes fixed on the water without seeing it, he knew that the abode of this gang of wretches was within a comparatively short distance of this spot in which he and his companions had taken refuge, and he knew, too, that there was every reason to suppose that some of them would soon be in pursuit of the negro who had run away.
Suddenly another dreadful thought struck him.
