> 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
> never run up on anything like it. Assistance would be appreciated. Thank
> you in advance.
