From the third grave came two bowls, both almost spherical, the one 12 inches, the other 6 inches, in diameter (fig. 24, _c_). At the point K, near the end of the mound G (fig. 22), three interments were found, very close together, on the ground level; these had evidently been contained at one time in a small oval cist, built of rough blocks of limestone, which had now completely caved in. With the bones were found the vases shown in figure 24, _b_, _f_, _h_, of the same red-painted pottery as was found elsewhere in the mound. Six well-made bone awls, or lance heads, each about 6 inches in length, together with a heap of the shells of some large bivalve, one of which was polished and perforated for use as an ornament, were also found among these bones. The stones of which the cist had been built, the bones, and the objects accompanying them were so inextricably mixed that it was impossible to tell which objects belonged to each set of bones. Passing through the long axis of this mound was a rubble-filled trench, 3 feet in breadth, dug down to the bedrock, exactly similar in structure to those already described. No interments were found at the sides of this trench, which is shown in figure 23, E. [Illustration: Flag of limestone shown in D, fig. 25.] [Illustration: FIG. 25.--_A_, skull; _B_, limestone formation; _C_, excavation; _D_, grooved flag in situ; _E_, projecting lip.] MOUND NO. 6 A Mound No. 6 A, another of the group of mounds adjoining the southwesterly boundary of Santa Rita, measured 18 feet by 15 feet at the base, by about 3 feet high at the highest point, and was built throughout of earth, large blocks of limestone, and limestone dust. The mound rested directly on the limestone formation. Into this, near the center of the mound, an oval excavation had been made (see C C, fig. 25) about 10 inches in depth, and in size just large enough to contain the skull which was found within it. A ledgelike projection was left at one edge of the excavation (see E, fig. 25), and just beneath this rested the point of the jaw. A large heavy flag of limestone (see D, fig. 25), from which a semicircular segment had been chipped, was placed above the excavation opposite the lip, so that the groove in the stone inclosed the neck and clamped the skull tightly down in the little hole which had been made to receive it. On each side of the skull the femora were found, in a nearly vertical position, condyles downward, and between the femora many fragments of other bones were brought to light, including the tibiæ, arm bones, and vertebræ. Resting upon the limestone flag which covered the skull lay a large, rudely made chert hammerstone, 8 inches long by 4 inches broad, which had probably been used in chipping out the semicircular groove to fit the neck. Near the center of this mound, 2 feet below the surface, two very neatly made flint hammerstones were found.
