Through a glass darkly

My allotment is next to an old 'hall'. It was at one time a large manor house though is now devided into three dwellings. I think our allotments were once part of its grounds, and in one particular area I often come across old fashioned junk, especially bottles of thick, dark glass. I chuck them into an old plant pot. One day I will sort through them and display my favourites as mini sculptures.
