While on a tour of research in the north central part of Chiba-ken, known as Imba-gun, the writer found two hundred and nine sites of stone-age remains.According to patterns on the pottery and their forms, they were classified into eleven types.He has then endeavored to show which type occupies what part of the precinct.Some of the sites cover a wide area, while others are quite small.It is generally supposed that the former type is older than the latter.He hopes that this work will supply some data in the study of the geographical distribution of types of stone-age pottery in this County.
