Michigan State excavated a brick clamp on the Tombigbee Waterway  Project 
in Clay County, Mississippi in 1980.  It was at the  Vinton site (1840s era) 
where Dean Anderson was my crew chief.

"As I ate the oysters  with their strong taste of the sea and their

faint metallic taste that  the cold white wine washed away, leaving

only the sea taste and the  succulent texture, and as I drank their

cold liquid from each shell and  washed it down with the crisp taste

of the wine, I lost the empty  feeling and began to be happy and to

make plans." - E.  Hemingway
