The local conditions (well-aerated, sandy :M ost of the charred seed samples are from the fill soil, above the ground-water level) do not allow of pits, ditches and post-holes. With pits one could the preservation of non-carbonized plant remains. possibly think of storage pits the contents of which The fil! at the bottom of the wells may have con were burnt, resulting in the carbonization of a tained water-logged vegetable material, but no smaller or larger number of grains. In this case the samples could be obtained from this type of soil. charred grains would be in a primary position, i.e. Some particulars of the samples which yielded more or Jess at the spot where they had become seeds and fruits are presented in table r. Fairly carbonized. It is difficult to imagine how grains often two or more samples are from one building ; could have become carbonized in the sandy fill of in such cases the samples are mainly from post post-holes. The grains must have been deposited holes which form part of the same ground-plan. In there in a charred condition.
