At Tsuishikari, 1 mile west of the town of Ebetsu is a sandy hill 

 bordering tho Toyohira River just south of its confluence with the 

 Ishikari River. This sandy emminence is probably part of an ancient 

 sand-dune system. On this hill Japanese archeologists excavated 

 many Ainu graves. These graves were not old, some being as recent 

 as the middle of the 19th century. The graves yielded human bones 

 in excellent condition, accompanied by iron swords and kettles, glass 

 beads, brass wire ornaments, and other trinkets obtained by the 

 Ainu from trade with the Japanese. In the topsoil between the 

 graves and in some instances included in the backfill of the graves 

 were found Jomon Period sherds and stone artifacts. During the 

 present investigations, a 10-foot square test was dug to hardpan, 

 but no graves or other features were met. In the topsoil of the test 

 square and on the surface of the site were found the following:
