At the bottom of the inset is an opening where workers raked the calcined lime out of the kiln. A cement floor covered the rake out area with a small shed-like structure over it to protect the lime from rain. Barreled lime from the kiln was sold locally to farmers and builders at the kiln where the purchasers hauled it off by horse and wagon.
