1897). Laufer also pointed out that the only reference that he could find in Chinese literature to pottery of the Han Dynasty is by Chow Mi in the Kuei Hsin Tsa Shih, Chow Mi lived under the Southern Sung Dynasty in the thirteenth century.
Such an observation by Laufer is of importance because he was an established authority on Chinese archaeology. As Curator of Anthropology at the Field Museum of Natural History in Chicago he was in China from 1901 to 1904 collecting specimens and making investigations with the Jacob H. Schiff Chinese expedition. He returned again to China in 1910 with the Mrs. T. B. Blackstone expedition. While he collected most of his Chou and Han pottery mainly in Shensi Province he also travelled widely in China and visited Canton and Hong Kong. Thus he would certainly have reported Han pottery if it had been known in the area.
This relatively recent discovery of neolithic archaeology in China is certainly paralleled here in Hong Kong. The first reference to it that I can find is by Dr. C. M. Heanley in 1928 when he described Hong Kong celts (8). Dr. Heanley, who fortunately is still active and keenly interested in Hong Kong (I received a letter from him recently), lives in Salisbury, Southern Rhodesia. He was head of the Government Vaccine and Bacteriological Department and in his spare time was a devoted amateur geologist. He knew of Laufer's work and in his article on celts referred to Laufer's statement that prehistory stone implements were scarce in China. Heanley suggested that they were only scarce because prospectors did not know how to look for them. He said, "To find celts in South China select the crests and spurs of granite hills bared of vegetation by rain erosion. Do not look for celts but look for isolated fragments of pottery and water-worn stones. The eyes should be kept ranging well ahead and on either side and little attention given to the ground near the feet." Heanley estimated that on granite outcrops in Hong Kong there was an average of about 30 to 40 celts to the square mile within 600 yards of the sea and land reclaimed from the sea.
Dr. Heanley's shrewd advice to prospectors has helped considerably in later searches. It is on raised beaches, terraces and hill-spurs that most of our archaeological remains have been
