proper, but from the surrounding fill and the plowed topsoil above 

 the chamber were taken five grit-tempered sherds possibly repre- 

 senting two wares, drill fragments, thin stemmed and corner notched 

 arrowpoints, crudely chipped blades, a broken sandstone abrader, end 

 scrapers, hematite, and fragments of polished igneous stone. Har- 

 rington concluded that "the method of laying up the stone vault 

 resembles so closely the many mounds of this type excavated by 

 Fowke along the Missouri Kiver in central Missouri that the com- 

 ponent represented at Bo 1, in all likelihood, belongs to the same 

 cultural manifestation." 



During the following summer two other mounds were investigated, 

 both on the bluffs of Perche Creek overlooking the Missouri about 

 7 miles southwest of Columbia (Berry et al., 1938). The first, 

 Bo 4:2, about 30 feet in diameter by 3 feet high, had a roughly 

 circular chamber about 2 feet high and 8 feet across, with walls 2 

 feet thick. No doorway is mentioned. Human bones, mostly dis- 

 articulated and ill preserved, were found in the enclosure, while 

 the mound fill outside yielded some fragments and a few whole skulls. 

 "Within the vault were the incomplete remains of about 12 extended 

 supine burials with heads toward the northeast. Bundle burials 

 were about equally numerous. Among both extended and bundle 

 burials were some that had been burned, and evidences of fire occur- 

 red on a few of the isolated fragments as well. It is estimated that 

 about 30 individuals were represented. Cultural material was found 

 in as well as outside the vault. This included about 100 soft grit- 

 tempered sherds, 6 of which were vertical rims from small pots; 

 partly smoothed over incising was present on 3 or 4 fragments. 

 Two clay pipes, 1 of elbow type with conical bowl, and a fragment 

 of a third with incised lines encircling the top of the bowl, came 

 from the mound, but whether out of the vault or from the surround- 

 ing fill is not clear. Otherwise, there were stemmed and notched 

 arrowpoints, a crude scraper, the basal portion of a drill, parts of 2 

 bone awls, and 2 bits of hematite. 



The second mound. Bo 5, measured 60 by 45 by 10 feet. Its central 

 feature (Berry et al., 1938, pp. 27-33) was a roughly square stone 

 enclosure 10 by 8 feet across, with walls about 2 feet high and 3 to 3i/2 

 feet thick. At the level of the base of the wall inside the vault, was a 

 flagstone floor ; another layer of rock comprised a roof. The remains 

 of at least 10 or 12 individuals were in the vault. These included 5 

 articulated extended primary burials, 2 bundles, cremations, possibly 

 a semiflexed interment, and fragmentary remains. Artifacts found 

 among the bones included 2 cylindrical antler objects, each with 1 

 socketed end, and a third without the socket ; the pierced leg bone of 

 a deer; a rough splif.-bone awl; a tubular bone bead; a shell spoon
