"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.

"Who are these, Rufinus?" he demanded of the under-officer.

"A barbarian chief and warriors from the villages of the western shore," replied Rufinus. "They bring two prisoners that they captured in the Rupes Flumen. As a reward they wish permission to enter the city and see the Emperor."

"How many are they?" asked the officer.

"Sixty," replied Rufinus.

"They may enter the city," said the officer. "I will give them a pass, but they must leave their weapons in their canoes and be out of the city before dark. Send two men with them. As to their seeing Validus Augustus, that I cannot arrange. They might go to the palace and ask the praefect there. Have the prisoners come ashore."
