Both brick and lime kilns are present in the "James Citty" area, each
type being represented by four examples. The oldest of four brick kilns
so far discovered on the island is a small rectangular pit near Orchard
Run, excavated to a floor depth of 4 feet, which has been dated between
1607 and 1625 by associated cultural objects. This small pit, without
structural brick, was a brick-making "clamp," consisting of unfired
brick built up over two firing chambers. There is good evidence that a
pottery kiln was situated 30 feet west of the "industrial area."
