Following the SHA Meeting in Baltimore (I think it was that meeting),  Lester 
Ross met with me in San Diego to discuss developing a research design  that 
predicted in advance what metal by-products and scraps could be predicted  from 
various activities within a blacksmith shop (workbench, foundry, forge,  
anvil, etc.). My challenge at the time was to design a method for distinguishing  
1860s blacksmith debris from 1916 +/- U.S. Army occupation of the same 
building.  Ross used information gleaned by Parcs Canada in blacksmith shop 
investigations.  Unfortunately, the Army really smeared the old blacksmith shop before 
it burned  in 1919 and we could never get a real handle on the blacksmith 
traces. I  recommend communication with Parcs Canada with regards to 
identification of  waste materials. Lester would be a good contact too, but he is probably 
reading  this message.
