doubtless, swarm with the yellow-fever mosquito. The sick seem to have recovered swiftly--a trait observable in yellow-fever patients. This, says the narrative, "was the first and last experiment that our Captain made of anatomy in this voyage." The surgeon who made this examination "over-lived him not past four days"--a fact which very possibly saved the lives of half the company. He had had the sickness at its first beginning among them, but had recovered. He died, we are told, "of an overbold practice which he would needs make upon himself, by receiving an over-strong purgation of his own device, after which taken he never spake; nor his Boy recovered the health which he lost by tasting it, till he saw England." He seems to have taken the draught directly after the operation, as a remedy against infection from the corpse. The boy, who, perhaps, acted as assistant at the operation, may have thought it necessary to drink his master's heeltaps by way of safeguard. While the company lay thus fever-stricken at the fort, the Maroons had been wandering abroad among the forest, ranging the country up and down "between Nombre de Dios and us, to learn what they might for us." During the last few days of January 1573 they came in with the news that the plate fleet "had certainly arrived in Nombre de Dios." On the 30th of January, therefore, Drake ordered the _Lion_, one of the three pinnaces, to proceed "to the seamost islands of the Cativaas," a few miles from the fort, to "descry the truth of the report" by observing whether many frigates were going towards Nombre de Dios from the east, as with provisions for the fleet. The _Lion_ remained at sea for a few days, when she captured a frigate laden with "maize, hens, and pompions from Tolu." She had the Scrivano of Tolu aboard her, with eleven men and one woman. From these they learned that the fleet was certainly at Nombre de Dios, as the Indians had informed them. The prisoners were "used very courteously," and "diligently guarded from the deadly hatred of the Cimmeroons," who used every means in their power to obtain them from the English, so that "they might cut their throats to revenge their wrongs and injuries." Drake warned his allies not to touch them "or give them ill countenance"; but, feeling a little doubtful of their safety, he placed them aboard the Spanish prize, in charge of Ellis Hixom, and had the ship hauled ashore to the island, "which we termed Slaughter Island (because so many of our men died there)." He was about to start upon "his journey for Panama by land," and he could not follow his usual custom of letting his prisoners go free.
