It is inexpedient to pursue this particular subject to any great extent, for it is made clear by the reports of the Spanish authorities that the relations of the governing class of the Quichés to the other Indians under their rule were those of a race of conquerors to a race of slaves, and the victors treated those whom they had conquered in a manner in accordance with the habits of a savage and barbarous tribe of North American Indians. This much may be admitted from the consideration of the circumstances of the laws and customs of the Quichés at the time of the arrival of the Spaniards. But if a due estimation is also given to the evidence afforded by the strange and otherwise inexplicable similarities in the methods of choosing fortified positions and raising ramparts with those in Ohio, it becomes reasonable to infer that the Quiché chiefs originally migrated from that part of North America. It is however necessary to note that, at whatever period their migration may have taken place, it cannot be granted or inferred that the Ohio tribes brought with them any knowledge of architecture, or of any form of civilisation, for had it been otherwise, they would have left behind them some vestiges of that civilisation or mechanical skill. It is especially remarkable that throughout the length and breadth of North America there is not the smallest fragment of any hewn stone building, or of any carved stone hieroglyphic characters. Thus the theory of migratory tribes of Indians bringing with them from the North into Mexico, a comparatively advanced knowledge of arts and sciences is opposed to all evidence. It is almost certain that the state of civilisation that at one time existed in the regions of Chiapas and Yucatan, was introduced into the country at some period subsequent to the arrival of the invading tribe, unless it can be established that the aboriginal races already possessed a competent intelligence, and an architectural capacity. A proposition of this character cannot be reasonably maintained, for it is known that in the fifteenth century the Indians in Cuba and Haiti, the Caribs on the coasts south of Yucatan, and the aborigines in the interior were savages, existing in a low state of human intelligence. This subject respecting the Indian migrations and the state of civilisation that was existing, or had existed, in Central America, can be more definitely considered after attention has been directed to the question of the antiquity and purpose of the buildings at Palenque and Uxmal. It is much to be regretted that Palenque was not known to the Spaniards when Cortes marched within a few leagues of it in 1524. Possibly, at that time it had not been long abandoned, and perhaps some of the caciques dwelling in that part of the valley of the Usamacinta might have been able to explain the meaning of the hieroglyphs. Unfortunately the ruins were not discovered until more than two centuries had elapsed,
