But to start for the coast without knowing the geography of the country was sheer madness, and Jack stamped his foot with rage as he thought of the miles of trackless forest which lay between him and freedom. To push one's way through a virgin forest is difficult in any case, but to make the attempt without arms, companions, food, and guides was quite an impossibility. That there was some secret way to the coast was plain, as the Indians came hither to this shrine from Tlatonac; but that way was known only to the priests. Within a certain distance, every new-comer was blinded with a bandage, and this was taken off in the square, before the principal teocalli. The worshippers were conducted into the forests with the same precautions; so, unless he could bribe a priest to show him the secret way, Jack foresaw absolutely no chance of gaining his freedom. It was a buried city, but not a ruined city, for here the aboriginal civilisation flourished greatly, as it had done before the coming of the Spaniards, to Anahuac. Situated in a hollow cup, on all sides arose verdant forests of bright green, clothing the base of great mountains, which showed their serrated peaks above the vegetation. On three sides the city was shut in by these giant barriers, but towards the west opened a rugged cañon, through which flowed a noisy stream. A road ran along the west side of this freak of nature, cut out of the solid rock, so narrow as to allow only three men to walk abreast. Above and below were the cliffs, thousands of feet in height and depth. No foe could enter the city by that pass, which led into the great mountains of the interior continent; but no foe would wish to enter, for this city was holy ground, the Mecca of the aborigines, and had preserved its inviolability from an invasion for centuries. "It was built by the Toltecs, Señor," said Cocom, who acted as Jack's cicerone. "Ages ago, you must know, this race came hither from the North. It was they who built the great cities of Yucatan in the dark past. Uxmal, Aké, Chichen-Itza. They reared them all. A glorious race were my ancestors, Señor." "But you are not a descendant of the Toltecs, Cocom?" "No, Señor, I am a Maya. My ancestors ruled at Mayapan. See," added the Indian, plucking a yellow flower sprouting out from a crevice close at hand, "this is the plant Cocom--my name, Señor, and that of the great kings who ruled Yucatan. The Mayas also built great cities, but Toltecs or Mayas, Don Juan, what does it matter? I am a poor Indian crushed under the heel of the white man." "You say the Toltecs built this city also?"
