At San Domingo Dr. Coller showed me a chart which he had drawn of the country around for a distance of twelve miles, exclusive of the neighbourhood of Palenque where the forest prevented him from making a survey. Upon this chart he had placed the positions of eleven mounds that he had discovered. They were situated near the left bank of the Usamacinta. On the slopes of these mounds were loose slabs of worked limestone which he thought must have formed part of houses built on their summits. Some excavations had been made and it was proved that the mounds were not burial places. I met in the village the proprietor of a small hacienda near Balancan. He told me that in one of his fields there was a large mound forty feet high, which must have had a building upon it, for on the top there were large blocks of squared stone. He wished to know what the mound contained and had therefore dug through it, but he found nothing but a curved grindstone precisely similar in shape and size to those now used by the women in the neighbourhood. In the adjoining land he had found near the surface numerous terra-cotta idols, but he had not seen any human bones. It is a coincidence perhaps of some importance, with reference to the origin of the race once occupying Palenque, that a grindstone was also the only thing found within the mound opened by the orders of Carrera on the plains of Mixco, in that part of Central America which, before the conquest, had been occupied by the Quichés. San Domingo is occasionally visited by groups of the wild Indians called Lacandones who live isolated amongst the adjacent forests. Dr. Coller told me that during his ten years’ residence, he had seen several of these men enter the village for the purpose of exchanging beans, tobacco and wax for spirits and other goods. They were always dressed in long white cotton frocks which reached nearly to their feet, and they wore their hair loose and very long. They seemed to be of a shy and inoffensive disposition. It is probable that they are of the same tribe as the Indians who live scattered amongst the Cordilleras near Comitan, a few of whom occasionally come down to that town from the forests bringing for barter bags of cocoa beans.
