Excavations on this site, which has a frontage of 130 feet on the west side of Princes Street, beginning 110 feet north of Mansion House Street, were watched from January 1928 by Mr. Quintin Waddington of the Guildhall Museum, and from September 1928 until the close of excavation in January 1929, by the present writer also. Digging usually proceeded in narrow shafts, the sides of which were boarded up as the work went on, whilst the use of day and night shifts made progress rapid, so that it was only possible to obtain occasional and incomplete views of stratified matter. However, it proved possible to make periodical examinations of the pottery from a number of separate shafts; and a limited amount of trial excavation during the men's dinner-hour was also carried out.
