Note 13 — EXCURSION I.
Reading edition
Truro being one of the privileged coinage towns, more tin is exported here than at any other port in the county: great quantities of copper are also exported from hence to Swansea and Neath in Wales. The blocks of tin lie in heaps about the streets, and are left entirely unguarded, as their great weight renders the difficulty to remove them so great, that it is never attempted.
