Privy

[olddump]

I was looking for a lost cat in the area and was looking in some old shacks on this property [nobody lives here]. One of the shacks was the acctual out house [complete seat and all. Now how can some one go about extracting the bottles from this without digging the place up. I.E. from the seat hole?? I have permision so that is not a problem. It is a brick lined privy that I need to get the bottles from the top. Any help on this????
