CULTURAL SEQUENCES IN HOKKAIDO MacCORD

At the bottom of the black zone was a small oval hearth, 30 by 

 26 inches across, identified by the reddish condition of the clay sub- 

 soil. This reddening extended 3 inches into the clay. No concen- 

 trations of sherds or other remains were found on or near the hearth, 

 and no postmolds were noted in the tested area. 



One restorable vase of Haji type (411628) was found in the test 

 trench. This vase is made of grit tempered clay, is brown, and is 

 4K inches high. The base is 2 inches across and is plain and slightly 

 concave. The ware is completely plain, though a line of vertical 

 fingernail impressions parallels the rim )i inch from the lip. The rim 

 top is pointed and slightly everted. 



A second vase (411629) found in the tested area is not restorable, 

 but is a good example of a globular jar of the Ebetsu type. This jar 

 is grit tempered and yellow. The rim diameter is 3 inches, while 

 the base is 3% inches across. The base is plain. The upper half of 

 the vase is covered by six bands, each % inch wide, of horizontal 

 cord impressions, while the lower half is covered by similar marks 

 running vertically. No design is found adjacent to the rim, which is 

 square and slightly everted. Maximum diameter of the globular 

 part of the jar is 6K inches. Overall height cannot be determined, 

 due to the lack of essential parts, but it is in excess of 7 inches. 



Since it was decided to excavate two of the visible housepits, a 

 base line was staked near the two depressions. This lino ran almost 

 due north and south, with both housepits east of the base line. Fig- 

 ure 4 shows the shape, size, and relationships of the two excavated 

 housepits.
