perishable wooden structures that have left the least evident traces,
such as frame sheds for forges and wine presses, carpenters' shops, and
buildings used by various artisans and craftsmen. So far, only two
industrial structures are clearly recognizable (aside from kilns),
although their precise use is not certain.

One of these, on the edge of Pitch and Tar Swamp, was a nearly square,
tile-floored workshop with a rough but substantial brick foundation
supporting the framework of the walls. On the floor were 3 fireboxes, 2
of which were associated with a large chimney area. What was fabricated
here has not yet been determined, although ceramic firing, brewing,
distilling, and even ironworking, have been suggested. Proximity of
pottery and lime-burning kilns, and a small pit where iron may have been
smelted, may be significant.

A second, very fragmentary brick foundation close to the present
riverbank suggests a shop rather than a house, but lacks firebox
evidence or other identifying features. It may be 18th- rather than
17th-century.

Brick Walks or Paved Areas

It is difficult to assign a use for certain areas which have been paved
apparently with brick rubble, or, in more evident cases, by flatlaid
