Montreuillon
Montreuillon lies on the upper Yonne in the wooded Morvan. Its river became part of the great trade in firewood for Paris: logs cut in the forests were released into streams and carried downstream to Clamecy, where they were assembled into rafts. A company of local merchants formed in 1763 organized transport from the Morvan ponds to the Yonne. Its river keeper at Montreuillon supervised marked timber, cleared obstructions and saw that damaged waterworks were repaired after a float.
