    "They gave the officers to understand that far from wishing to act as enemies, they were willing to afford the shipwrecked people all the assistance in their power; but these barbarians shewed, on all occasions, a perfidiousness which is peculiar to the inhabitants of these climates; when the brig had sent biscuit on shore, they seized the half of it, and a few moments after, sold it at an exorbitant price, to those from whom they had stolen it."
