> We have been evaluating a site in Anne Arundel County, Maryland which, 
> according to records, was first constructed in 1820. Currently the site 
> consists of a basement constructed of fieldstone and the poured concrete 
> foundations of later additions. The structure was occupied through most of 
> the 20th century and burned in the 1960s. It was vacant/empty at that time. 
> Close interval shovel testing has resulted in the recovery of substantial 
> quantities of architectural metal (i.e. nails of all types) and little else. 
> 
> The point being - that we recovered two rusted iron ring-like things with 
> glass (now melted) insets. The exterior dimension of the ring is 2 inches. 
> The interior diameter is 1 3/4 inches. The extensions for the nails are 1/4 
> inch. The wire nails are 2 1/4 inches. The glass appears to have been aqua 
> in color and quiet thick.

> My first thought is that they are lighting fixtures of some type but I have
