An old anthropology prof of mine told us about finding an abandoned mine in which was a treasure trove (to an anthropologist anyway): garbage from the Yukon Gold Rush days. Seems the two 'things' in greatest supply were empty bottles of Champagne (Mum's?)sp?)) and Lea and Perrins Worcestershire Sauce. They figured the L and P's was used to help get the meat of horses and mules so it was palatable. The Champagne? Beats me.
