There is also among his papers the commencement of an address or essay upon these ruins, written in Spanish, and this, when completed, may have been printed in some Mexican periodical. I translate from it the following passage, the remainder having been lost: "Having learned that in the forests of the coast between the _barras_ of Chiltepec and Grijalva various mounds, idols and other remains of an earlier population had been discovered, I proceeded to that part of the country called _Del Cajete_, and devoted six weeks to its exploration. I soon found numerous mounds and embankments from which the present inhabitants had gathered fragments of idols and milling stones of a form unknown now in the vicinity. "It very soon became apparent that these mounds were not such as those isolated ones which are found in various parts of this country, but were arranged in groups surrounding open spaces, _plazas_, and forming streets, extending over an area three leagues in length by one in breadth. [Illustration: _Fig. 2.--The Great Temple._] [Illustration: _Fig. 3.--Cross Section of Fig. 2, B._] "Not a single tradition, not a single native name survives to cast any light upon these ruins. The whole of this coast was depopulated in the seventeenth and eighteenth centuries owing to the slave-hunting incursions of the filibusters and man-hunters. The Indians who are now found in the neighborhood have removed there from the interior since the beginning of the present century, and are absolutely ignorant of the origin or builders of this city, hidden in the tropical forest." The locality referred to as _Del Cajete_ was a settlement (rancheria) of Indians, now better known as San Jose de la Bellota, on a large pond into which drains the Rio de la Bellota. It was founded in 1815 by a cura who brought the Indians there from the other side of the river, back of Frontera. The general position of the ruins will be seen from the above map. It is drawn to the scale of the Mexican league, which contains 5000 yards (varas) each 838 mm. One league is therefore approximately two and three quarters of our miles. No ruins or mounds were located immediately on or near the coast. Almost a continuous line of mounds, embankments and heaps of debris extends from near Bellota for about nine miles in a general west-south-west direction over a plain which is now densely covered by a tropical forest. Dr. Berendt did not attempt to survey but a few of these numerous monuments. The plan of one of the largest, called by the natives _El Cuyo Grande_, "The Great Temple," is shown in the following, figure 2. The principal mound B is terraced about half way up and was 82 feet in height. A cross section of it is shown in Fig. 3, A-B.
