Prior, the natural Indians came to the see because of the oysters. They
took so many of them that they left behind mounds of shells, and the nucleus,
they took in order to eat during the year and over those mounds, long the
years, large and big trees grown and the Portuguese found some of them and each
day they find others again and from these shells thel make lime and from one
single mounf they buit part of the Bahia’s school, the Government building and
many others buildings and the [shell mouds] are not extinct yet.
