Draining off the tar

It was possible to drain off as many as twenty barrels of tar from a large tar-burning pit. Below the wooden pipe was a two-cubit long trough with a tap made from wood, or sometimes horn which was used to drain off the tar into barrels. When the barrels were full, they were rolled from the gully onto boards in rows, bung upwards. After a couple of days, wood vinegar that had sunk to the bottom of the barrels was drained off.
