Greetings,
 
I would like to know if anyone has information about Cornish-style buddles
on mining sites in the United States. Circular convex buddles were a
popular mid-19th century ore-processing technique in Cornwall, but I have
been unable to find reference to any in this country (except for two
recently uncovered in Upper Michigan). Any information would be greatly
appreciated.
 
Thanks in advance,
