The local Purbeck quarries are a gift for us West Country smugglers. Much of the stone is moved on by by sea. With all the boats to-ing and fro-ing the Excisemen don't notice an extra ship or two berthing alongside the stone ships. The quarries have a maze of passages and trenches, and if you're being chased you can dart down a tunnel and soon be hidden behind a pile of rubble, or a slab waiting to be dressed. The quarrymen are rewarded for helping us out...if you get my drift!
