varying size, being ordinarily, however, ten inches in diameter and four and one fourth inches high. Both inside and outside are painted with figures which from their uniformity in different specimens are deemed by Mr Boyle to have some hidden hieroglyphic meaning. It is also remarked that vessels intended to be of the same size are exactly equal in every respect. Another common vessel is a black jar, glazed and polished, about four inches high and five and one fourth inches in diameter, made of light clay, and having a simple wavy ornament round the rim. Animals or parts of animals, particularly alligators, often form a part of the ornamentation of pottery, but complete animals in clay are rare, a rude clay stag being the only relic of the kind reported. The device of a beast springing on the back of a human form, so frequent among the statues or idols, also occurs in terra cotta. The four figures of the cut show additional specimens in terra cotta from Mr Squier, of which Fig. 2 is from Ometepec.[II-64] [Illustration: Ometepec Tripod Vase.--Fig. 1.] [Illustration: Bowl from Zapatero.--Fig. 2.] [Illustration: Nicaraguan Figures in Terra Cotta.] [Sidenote: RELICS OF THE USE OF METALS.] It only remains to speak of the sixth and last class of Nicaraguan relics; viz., articles of metal, which may be very briefly disposed of. The only gold seen by any of our authorities was "a drop of pure gold, one inch long, precisely like the rattles worn by Malay girls," taken by Mr Boyle from a cinerary vase at Juigalpa. But all others mention small gold idols and ornaments which are reported to have been found, one of them weighing twenty-four ounces; so that there can be but little doubt that the ancient people understood to a limited extent the use of this precious metal, which the territory has never produced in large quantities. Copper, on the contrary, is said to be abundant and of a variety easily worked, and yet the only relic of this metal discovered is the copper mask, which Mr Squier supposes to represent a tiger's face, shown in the cut. It was presented to him by a man who claimed to have obtained it from Ometepec. Mr Boyle believes, with reason as I think, that in a country abounding in the metal, the skill and knowledge requisite to produce the mask would most certainly have left other evidences of its possession. The authenticity of this mask, when considered as a Nicaraguan relic, may be regarded as extremely problematical.[II-65] [Illustration: Copper Mask.]
