The seventh season of excavation at Can Hasan began on 9th September and stopped on 28th October; a further week was spent working on the finds and on the site. Site supervisors were Bay Altan Atılgan, and Messrs. S. W. Helms, R. Howell, and J. N. Postgate. In the House the work was undertaken by Bayan Behin Aksoy, Bayan Ülge Göker, Miss Carolyn Prater, Mrs. Cressida Ridley and Miss Monika van der Zwann. Bay Bedri Yalman represented the Turkish Government for a short period until called away to military service; his place was taken by Bay Cengiz Karadağ.A new method of sieving was introduced this year at the suggestion of Mr. Sebastian Payne. Instead of small hand sieves, “shakers”, built under Mr. Payne's supervision, were used. Basically this type of “shaker” is three removable trays with mesh of differing size (10 mm., 5 mm., 1 mm.) set on a sprung metal framework. It was also found more practicable with soils containing a lot of grain to “wash out” the grain from the soil remaining in the last tray after the soil had received preliminary hand-searching.
