After two hours of marching the trail turned sharply to the right and entered a narrow and rocky gorge, the entrance to which was so choked with trees and undergrowth that it could not have been visible from any point upon the slopes below. The gorge soon narrowed until its rocky walls could be spanned by a man's outstretched arms. The floor, strewn with jagged bits of granite from the lofty cliffs above, afforded poor and dangerous footing, so that the speed of the column was greatly reduced. As they proceeded Tarzan realized that, although they were entering more deeply into the mountains, the trend of the gorge was downward rather than upward. The cliffs on either side rose higher and higher above them until in places the gloom of night surrounded them and, far above, the stars twinkled in the morning sky. For a long hour they followed the windings of the dismal gorge. The column halted for a minute or two and immediately after the march was resumed Tarzan saw those directly ahead of him filing through an arched gateway in the man-made wall of solid masonry that entirely blocked the gorge to a height of at least a hundred feet. Also, when it was the ape-man's turn to pass the portal, he saw that it was guarded by other soldiers similar to those into whose hands he had fallen and that it was further reinforced by a great gate of huge, hand-hewn timbers that had been swung open to permit the party to pass. Ahead of him Tarzan saw a well-worn road leading down into a dense forest in which huge, live oaks predominated, though interspersed with other varieties of trees, among which he recognized acacias and a variety of plane tree as well as a few cedars. Shortly after passing through the gate the officer in charge gave the command to halt at a small village of conical huts that was inhabited by blacks not unlike the Bagegos, but armed with pikes and swords similar to those carried by the legionaries. Preparations were immediately made to camp in the village, the blacks turning over their huts to the soldiers, quite evidently, judging from the expressions on their faces, with poor grace. The legionaries took possession of whatever they wished and ordered their hosts about with all the authority and assurance of conquerors. At this village a ration of corn and dried fish was issued to the prisoners. They were given no shelter, but were permitted to gather deadwood and build a fire, around which they clustered, still chained neck to neck. Numerous birds, strange to Tarzan, flitted among the branches of the trees overhead and numerous monkeys chattered and scolded, but monkeys were no novelty to Tarzan of the Apes, who was far more interested in noting the manners and customs of his captors.
