had been found at or near the center, an excavation 14 feet by 7 feet 
was first made in the center of this mound down to the ground level. 
For the first 3 feet the mound was composed of yery small stones and 
earth. Beneath these was a layer of rough blocks of limestone and 
limestone dust reaching to the ground level. At a depth of about 4 
feet a smooth, oval, flattened stone 5 inches in length was found, the 
marks on which showed that it had been used as a whetstone. With 
the exception of potsherds, nothing else was found in this excavation, 
which was afterward enlarged on all sides, but with a similar result, 
nothing whatever but stones and earth being found. 
The mounds 12, 13, 14, 15, and 16 in the plan lay ina group to 
the northeast of the large central mound, and within 200 yards of it. 
They were all circular at the base and roughly conical, and were all 
nearly of the same size, varying from 30 to 35 yards in circum- 
ference and from 4 to 6 feet in height. In contents and construction 
they all proved so much alike that a description of one will suffice for 
all. The two upper feet consisted of earth, with a few blocks of lime- 
stone; beneath this, to the ground level, the mound was built of lime- 
stone blocks, the interstices between which were filled in with limestone 
dust. A few potsherds were found, for the most part rough and 
unpainted. At a depth varying from 2 to 3 feet, or about midway 
between the summit of the mound and the ground level in each case, 
a small stone cyst was found, 18 inches square, the walls, roof, and 
floor each composed of a single slab of roughly cut stone. These cysts 
were in all cases perfectly empty, and were placed as nearly as possible 
in the center of the mound. Nothing further was found in any of 
the mounds. 
The mound marked 17 on the plan stood 500 yards almost due 
sast of the large central mound. It was oyal in shape, flattened 
on the top, 85 yards in circumference, and 6 feet high at its highest 
point. The northern face was almost perpendicular; the southern 
sloped gradually to the ground level. The upper two feet consisted 
of earth and blocks of limestone. Near the center of the mound, 
at a depth of 1 foot, were found the fragments of two idols very 
similar to those found in mounds 2, 5, and 6. Close to these were 
found: (1) The flat, triangular head of a serpent, with protruding, 
forked tongue; this was made of pottery, and had been broken off from 
the body; (2) a small, pyramidal pottery stopper, like those placed over 
the openings in the pottery animals; (3) a dragon’s head in pottery, 
with an elaborately decorated headdress; (+) a small pottery mold, 4 
inches in height, for making masks. After first oiling the inside of it, 
J filled this mold with plaster of paris, and it turned out a face very like 
figure 3, plate xxx, but without the headdress. Beneath the layer 
of earth and limestone came a layer of limestone blocks, many of 
which were squared. This was the last mound opened, and as in 
mounds of similar construction in which two broken idols had been
