They had been paddling for hours, and the heat and the monotony had become almost unbearable, when a turn in the water-lane revealed a small body of open water, across the opposite side of which stretched what appeared to be low land surmounted by an earthen rampart, along the top of which was a strong stockade. The course of the canoe was directed toward two lofty towers that apparently marked the gateway through the rampart. Figures of men could be seen loitering about this gateway, and as they caught sight of the canoes a trumpet sounded and a score of men sallied from the gateway and came down to the water's edge. As the boat drew nearer, von Harben saw that these men were soldiers, and at the command of one of them the canoes drew up a hundred yards offshore and waited there while the chief shouted to the soldiers on shore telling them who he was and the nature of his business. Permission was then given for the chief's canoe to approach, but the others were ordered to remain where they were. "Stay where you are," commanded one of the soldiers, evidently an under-officer, as the dugout touched the shore. "I have sent for the centurion." Von Harben looked with amazement upon the soldiers drawn up at the landing. They wore the tunics and cloaks of Caesar's legionaries. Upon their feet were the sandal-like caligae. A helmet, a leather cuirass, an ancient shield with pike and Spanish sword completed the picture of antiquity; only their skin belied the suggestion of their origin. They were not white men; neither were they negroes, but for the most part of a light-brown color with regular features. They seemed only mildly curious concerning von Harben, and on the whole appeared rather bored than otherwise. The under-officer questioned the chief concerning conditions in the village. They were casual questions on subjects of no particular moment, but they indicated to von Harben a seemingly interested and friendly relationship between the blacks of the outlying villages in the papyrus swamp and the evidently civilized brown people of the mainland; yet the fact that only one canoe had been permitted to approach the land suggested that other and less pleasant relations had also existed between them at times. Beyond the rampart von Harben could see the roofs of buildings and far away, beyond these, the towering cliffs that formed the opposite side of the canyon. Presently two more soldiers emerged from the gateway opposite the landing. One of them was evidently the officer for whom they were waiting, his cloak and cuirass being of finer materials and more elaborately decorated; while the other, who walked a few paces behind him, was a common soldier, probably the messenger who had been dispatched to fetch him. And now another surprise was added to those which von Harben had already experienced since he had dropped over the edge of the barrier cliffs into this little valley of anachronisms--the officer was unquestionably white.
