Emergency excavations were carried out for the Ministry of Public Buildings and Works, during October and November 1963. This important site has for many years suffered from the attentions of untrained amateurs, whose diggings have done a considerable amount of damage. The added threat of building operations connected with the new power station occasioned the present excavations. The digging of a pipe-line by machine was watched.
