Mound No. 18
Mound No. 18, situated less than half a mile from the next preceding, was 10 feet high, 70 feet in circumference, roughly conical in shape, and firmly built throughout of blocks of limestone the interstices between which were filled with earth and limestone dust. At the bottom of the mound, near its center, resting on the ground, was a cist, about 2 feet in diameter, roughly constructed of large flags of limestone. Within this were found two vessels: (a) A basin-shaped specimen of thin pottery, painted reddish-yellow and polished throughout; on its inner surface is depicted, in fine black lines, an object closely resembling a four-leafed shamrock. (b) A vase of the shape shown in figure [63], 13 cm. high and 13 cm. in diameter. This is made of rather thick pottery; it is painted light yellow and polished throughout. On the outer surface of the rim, outlined in thin black lines, is the glyph represented in figure [64], which is repeated all the way round the circumference. No additional objects were found in this cyst, nor were there any traces of bones in it, or in the rest of the mound, which was afterward examined.
