Soon after he [Arabanoo] was taken the
small-pox raged among them with great fury and carried off vast
numbers of them. Every boat that went down the harbour found them
lying dead on the beaches and in the caverns of the rocks, forsaken
by the rest as soon as the disease is discover'd on them. They were
generally found with the remains of a small fire on each side of
them and some water left within their reach. How this disease got
among them it is impossible to tell, but it is supposed that they
had it among them before any European visited the country, as they
have a name for it.
