I can say a word on that subject now, but I did not want to widen the debate, as we had intended to deal primarily with Hadrian's Wall. However, we have had more time than we expected. When the present operation at Stonehenge is completed, we hope to turn our attention to limited excavations at Avebury. At present no work is actually in hand there. We shall work out our plans in consultation with the Ancient Monuments Board and we shall hope to have the assistance of experts to supervise and advise on the work to he done.
