Pottery would seem to be one of the least suitable materials for bells.

Here, however, bells of pottery in many shapes are found--little bells, with handles like the upper part of a human figure; larger bells, with curious flat handles set transversely; others, still larger, like cow-bells in size and tone, and curious cross-shaped bells, really a group of four united.

Among the whistles some are made into the shape of animals and birds and curious human figures; among the latter, some closely resemble ancient whistles from the prehistoric graves.

This black ware is made at Coyotepec, and when the objects are first taken from the kiln they are almost white; before they are cold, they are exposed to dense smoke, and thus assume their black color.

The brilliantly glazed green ware is the most attractive.
