Between 1928 and 1933 he directed four campaigns of excavations at Ain Shems (Beth Shemesh), and Time magazine reported that he found jugs and vases which represented a Bronze Age culture.[1]
One of his lifelong interest was the life of the Palestinian fellahin, an interest which started when he first worked for the American Friends School, and which resulted in three books.[2] The 1907 book The Peasantry of Palestine: The Life, Manners, and Customs of the Village is described as "a vividly accurate portrait of rural life in Palestine".[3]
