At some epoch it is evident that the whole island was under cultivation, which is proved by the stone fences that divide it into small parcels or farms like a checker-board. The island, like the whole of the Yucatan peninsula, has evidently been upraised from the bottom of the sea by the action of volcanic fires, and the thin coating of arable loam of surprising fertility which covers a substratum of calcareous stones, is the result of the accumulation of detriti, mixed with the residuum of animal and vegetable life of thousands of years. The greater part of this island is as yet archæologically unexplored. I have no doubt that thorough explorations in the depths of its forests and of the caves would bring to light very interesting relics, which would repay the trouble and expense. Rough and rude as is the construction of the monuments of the island, the architecture possesses the same character as that of the more elaborate edifices on the main land. The same design of entablature, with some little difference in the cornice, the same triangular arch, the same shaped rooms--long and narrow, but all on a miniature scale. They seem more like dolls’ houses than dwellings for man. One of the best preserved of these singular buildings was visited, and two other constructions, consisting of independent and separate arches, the only ones we ever met with in our rambles in Yucatan. The edifice formed at one time, with the two triumphal arches, part of a series of constructions now completely ruined. It was a temple composed, as are all structures of the kind, of two apartments, a front or ante-chamber, and the sanctuary or holy of holies. In this case the ante-chamber measures 59 inches in width by 2 yards and 33 inches in length, its height being 2 yards and 30 inches from the floor to the apex of the triangular arch that serves as ceiling. The sanctuary is entered through a doorway 1 yard high and 18 inches wide, and is narrower than the front apartments, measuring only 34 inches across. The whole edifice is externally 3 yards high, 4 yards 29 inches long and 4 yards wide. If we judge of the stature of the builders by the size of the building, we may really imagine this to have been the kingdom of Liliput, visited by Gulliver. The triumphal arches present the same proportions as the temple I have just described, which is by no means the earliest archaic structure. Old people are not wanting who pretend to have seen these _Alux-ob_, whom they describe as reaching the extraordinary stature of 2 feet. They tell us of their habits and mischievousness, tales which forcibly recall to our minds the legends of “the little people” so credited among all classes of society in Ireland. There can be no reasonable doubt but that a
