Vessel 1 from housepit 2 (411655) (plate 9) is an almost complete 

 vase of Satsumon (j'pe. Since the base is missing, the exact height 

 nnd base type cannot be determined. Overall height is in excess of 

 7 inches. The vase lias expanding sides with a maximum diameter of 

 5% inches, and a constricted neck having a diameter of 4 inches. 

 The rim is strongly flared with an oral diameter of 5 inches. The 

 paste is ellow clay containing a temper of fine quartz sand and minute 

 flakes of obsidian. The exterior is plain except for vertical marks of 

 scraping. No design is found on this vessel. 



Vessel 2 (411654) (plate 10a) is a small, shallow bowl made on n 

 potters' wheel. The characteristic spiral striations on the base 

 (plate 106) show the technique of severing with a cord the shaped 

 bowl from the pedestal of clay from which the vessel was formed. 

 The bowl is 2% inches high and has a Hat base and straight, expanding 

 sides. Oral diameter is 4% inches while the base is 1% inches across. 

 The clay is yellow and red. Tempering is primarily quartz sand. 

 The use of a high-firing temperature is indicated by the glazed surface 

 area roughly % inch square on one side. Since other vessels at the 

 site were made by the coiling method, the bowl is probably an impor- 

 tation, though from what source is not known. 



Vessel 3 (411651) is an incomplete shallow bowl apparently hand- 

 molded. Height is \y 2 inches, oral diameter is 4 inches, and basal 

 diameter is 1% inches. The clay is yellow with some areas of black 

 clouding. The temper is quartz sand with some obsidian flakes. 



Miscellaneous Sites 



In addition to the excavations carried out at the Taniguchi, Uenae, 

 and Tanaka Sites, surface collections were made at a number of other 

 sites in the Ishikari Plain region of Hokkaido. These sites yielded 

 materials representing most of the cultural periods of Hokkaido and 

 supplementing the data obtained from the excavations. The fol- 

 lowing brief descriptions of the sites and the materials collected at 

 each are arranged according to a cultural sequence based on the 

 excavations and on presumably parallel cultural evolution in other 

 parts of Japan. 



Preceramic (?) Period 



One mile east of the city of Iwamizawa at a place called Higashi- 

 Tonebetsu is a hilltop on which hundreds of obsidian and flint chips
