scheme, or water-works, it will be explained by other finds. Effigy jars were not confined to Mexico, for they are found in various parts of the United States, especially in Tennessee, but they are nowhere anything like those described from the Zapotec country. The Tennessee specimens artistically and mechanically are exceedingly crude, as are all attempts to delineate the human figure by the northerly Amerinds. Some of the most elaborate and at the same time artistic forms in Amerind pottery are found in Chiriqui,[95] a province just below Costa Rica. The old occupants of this region seem to have excelled in metal-working, stone-carving, and pottery, and probably in other arts the products of which are of a more destructible nature. As the line of demarkation between the North- and South-American cultures runs along the southern side of Nicaragua, practically on the line of the proposed Nicaragua Canal, the consideration of the Chiriqui products should belong perhaps with the South-American division, but being above the isthmus, they may be mentioned here for the sake of comparison. “The casual observer,” says Holmes, “would at once arrive at the conclusion that the wheel or moulds had been used, but it is impossible to detect the use of any such appliances.” And further: “On the exposed surfaces of certain groups of ware the polish is in many cases so perfect that casual observers and inexperienced persons take it for a glaze.”[96] There was extraordinary variety in this ware. There are whistles, drums, rattles, round vases with necks and without necks; vases of simple and vases of complex form; vases and jars with elaborate handles; vases with annular bases or feet; and vases with short or long legs, three in number generally. This field is so rich that it is practicable to give here only a suggestion of what it affords, and the reader is referred to the admirable paper by Holmes.[96] [Illustration: ZAPOTECAN TERRA-COTTA FUNERAL URNS FOUND ON CEMENT FLOOR IN FRONT OF TOMB 1, MOUND 7, XOXO, OAXACA, MEXICO Photographed by M.
