CULTURAL SEQUENCES IN HOKKAIDO MacCORD 495 



ments of celts, 2 projectile points (plate 7d), 2 drills or reamers 

 (plate 7,c,e), and 17 chipped scrapers (plate la-b). The majority of 

 the chipped implements are made of obsidian, though the presence of 

 a few chips of flint show that this material was used. The celt frag- 

 ments are small chips of polished diorite, too small to indicate the 

 dimensions of the tool. One lump of sponge iron (411643, plate 7/) 

 found in the humus seems to be contemporary with the housepit, 

 but no other evidence of iron working was found in the excavation. 

 Two postmolds found in the subsoil outside the housepit were vertical, 

 and do not appear to have been part of the house structure. 



Miscellaneous sherds from the trench outlining housepit 1 consist 



of the following:

Of the 13 bases, 12 are cordmarked and are 3 to Z% inches in di- 

 ameter. The remaining one is plain, 3 inches in diameter. 



Vessel 1 (411637) is an incomplete, nonrestorable bowl made of 

 sandy clay containing many fiber casts. The paste is yellow and buff. 

 It is a straight-sided bowl with a rounded bottom. The vessel is 

 cordmarked over the entire outer surface. Height of the bowl is in 

 excess of 8 inches. Rim diameter is 9 inches, while the base is about 

 3 inches across. The rim is straight and pointed in cross-section. 

 Short impressions of twisted cords are found on the inner edge of the 

 rim. Perforations for repair are present on each side of a break in 

 the side wall. 



Vessel 2 (411635) is a small vase-shaped cup 1% inches high. It 

 is made of sandy clay and is unevenly fired. Basic color is a reddish 

 orange, but black smoke clouding covers about one half of the sur- 

 face. The base is subconoidal. Sides flare outward to a maximum 

 diameter of 1% inches at a height of 1 inch. At the shoulder thus 

 formed, the sides narrow abruptly to a nearly vertical neck ){ inch 

 high. Rim diameter is 1 inch. The cup appears to have been 

 molded over a fingertip. The outer surface is plain, though the 

 neck is decorated with two parallel incised lines, which cut across a 

 zigzag line to form equilateral triangles between the shoulder and the 

 rim. The rim is straight and rounded in cross-section. 



Vessel 3 (411638) is a restorable bowl 5 inches high bearing at 

 least two crenelations 1 inch higher. The shape is that of a wide- 

 mouthed bowl with a flat bottom and straight, sloping sides. The 

 paste is a sandy clay of yellow and buff color. The entire outer sur-
