The second group of ruins stands away some three-quarters of a mile through the woods to the westward. We were attracted thither by the appearance of a gigantic clump of trees towering up above the others as if marking the spot of some ancient mounds. On arrival there we found that it did not consist of one mound but three, all joining at their base and of rough unhewn stone. They averaged about 40 feet in height. On the ground-level at the side of them stood a small one-roomed house, probably the home of a priest or custodian whose duty was to watch over these pyramids. These mounds were remarkable not only by the fact of their queer juxtaposition but for the fact that on careful examination we found no trace of a building of any sort upon the top of them. That they were artificial there can be no shadow of doubt. That they were look-outs like the mounds examined by us on the coast is impossible, for in the heart of the island they could have served no such purpose. What we would suggest is that Cozumel formed at one time a Mayan Valhalla where, by reason of the intense sanctity of the soil, the bodies of the greatest caciques and the most revered of priests were brought from the mainland to be buried in the sacred isle. Thus these three mounds we believe to be simply sepulchral, the excavation of which--a gigantic task--would probably prove of the greatest interest. We had heard a rumour of the existence in the northern woods of a large stone and cemented dome-shaped building, doorless and sealed all round. We tried to find this but failed. This, too, was probably a tomb. About a hundred yards to the north-east of this trio of mounds stood a castillo on a pyramid, the two-roomed building on the top being reached by a stairway on the south-west. The temple was unadorned by any paintings, ornaments or hieroglyphics, but was remarkable for the extraordinary smallness of the apertures which apparently served for doorways. The ground-plans of this ruined city which are reproduced will give some idea of its size.
