At the end they get rich and trendy. The amount of leaf-litter and hence soil, depends on good and bad rainfall. The site is 6 metres by 4 metres. Each single layer has at the bottom humus with artefacts grading to dense trampled humus without artefacts. The excavators record the finds of each layer of each grid, and the volume of each layer.
Finds consist of broken bottles and animal bones.
That looks like 12 categories of bottle fragments. Bones are Sheep and Cow vertebrae, sheep leg. Below I show the finds as 12 categories in 12 columns, and the provenance as 30 rows. When making up the numbers I found I needed lots of general conclusions. The finds are scattered round areas 1a, 3b, which have many artefacts.
