Victorian illustration to download showing a picture of men removing the bark from a felled oak tree. Some have climbed into the branches to chop them down using axes. Others use barking irons and peeling irons to remove the bark from the trunk. Children help to gather the bark into piles. In the background is a stack of logs which supports a shelter made from branches and twigs. Oak bark was used to tan leather – the bark contains tannin, which is acidic, and acts as a preservative.
