Mound No. 4 (No. 7 on the plan of the Santa Rita mounds)[31] has recently been excavated, together with nearly the whole of the earthwork on its south side. The mound was circular at the base, conical in shape, 57 feet in height, 471 feet in circumference, and was built of blocks of limestone held together by mortar. On the south side of the mound and continuous with it was a circular earthwork 100 yards in diameter. The walls inclosing the circular space varied from 10 to 25 feet in height. They were higher toward the north, where they were continuous with the large mound, and lower toward the south, where an opening 30 feet wide gave access to the inclosure. The summit of the mound was truncated, circular, and about 20 feet in diameter. [Illustration: FIG. 19.--Objects from Mound No. 4.] It was covered by a layer of alluvial earth 4 inches in thickness, on removing which the following objects were brought to light, lying on the layer immediately subjacent, near the center of the mound: (a) A leaf-shaped spearhead of very light yellow flint, 5 inches in length; (b) a leaf-shaped spearhead of reddish flint, 5-1/2 inches in length; (c) an eccentrically-shaped flint object (fig. 19, _a_), 4-1/4 inches in breadth by 2-3/4 inches in depth, of light grayish flint, very neatly and carefully chipped; (d) a large, well-made flint arrowhead, deeply grooved on each side of the base, 2-1/2 inches in length, and of light grayish color (fig. 19, _b_); (e) the broken end of a roughly chipped flint hook or crescent (fig. 19, _c_). With these flint objects were found a small red-stone bead and a quantity of pieces of broken images, as arms, legs, faces, hands, breastplates, etc., in rough pottery. Below the alluvial layer the mound was composed of large blocks of limestone, held together by mortar, giving it the consistency of masonry and rendering digging in it very difficult. At a depth of 6 feet a small oblong chamber was opened, built of rough blocks of limestone, about 8 feet by 3 feet, within which were found fragments of human bones, the head pointing to the north. At both head and feet a few very roughly chipped spearheads were found. At a depth of 10 feet another small chamber, 4 feet in length by 2 feet in height and 2 feet in breadth, was opened, also composed of rough blocks of limestone. Within this were four basin-shaped vessels; two, somewhat larger than their fellows, were superimposed upon them (fig. 20). These basins were made of rough pottery, colored yellow, with a broad red stripe round the rim. Each was pierced by a pair of small round holes, 1 inch apart, repeated at equal intervals four times round the circumference, about one-half inch from the margin. The perforations in the upper vase corresponded exactly to those in the lower when they were discovered, suggesting that they had been connected by cords of henequen fiber, _ti-ti_, or some perishable material which had disintegrated. It was considered certain that these
