"Sanguinarius fought against the barbarians of Germania in the 839th year of Rome."

"That was about eighteen hundred and thirty-seven years ago," von Harben reminded the officer, "and I think you will have to admit that there may have been much progress in that time."

"And why?" demanded the other. "There have been no changes in this country since the days of Sanguinarius and he has been dead over eighteen hundred years. It is not likely then that barbarians would change greatly if Roman citizens have not. You say you are from Germania. Perhaps you were taken to Rome as a captive and got your civilization there, but your apparel is strange. It is not of Rome. It is not of any place of which I have ever heard. Go on with your story."

"My father is a medical missionary in Africa," explained von Harben. "Often when I have visited him I heard the story of a lost tribe that was supposed to live in these mountains. The natives told strange stories of a white race living in the depths of the Wiramwazi. They said that the mountains were inhabited by the ghosts of their dead. Briefly, I came to investigate the story. All but one of my men, terrified after we reached the outer slopes of the mountains, deserted me. That one and I managed to descend to the floor of the canyon. Immediately we were captured and brought here."

For a while the other sat in silence, thinking.

"Perhaps you are telling me the truth," he said, at last. "Your apparel is not that of Castra Sanguinarius and you speak our language with such a peculiar accent and with so great effort that it is evidently not your mother tongue. I shall have to report your capture to the Emperor, but in the meantime I shall take you to the home of my uncle, Septimus Favonius. If he believes your story he can help you, as he has great influence with the Emperor, Validus Augustus."

"You are kind," said von Harben, "and I shall need a friend here if the customs of Imperial Rome still prevail in your country, as you suggest. Now that you know so much about me, perhaps you will tell me something about yourself."

"There is little to tell," said the officer. "My name is Mallius Lepus. I am a centurion in the army of Validus Augustus. Perhaps, if you are familiar with Roman customs, you will wonder that a patrician should be a centurion, but in this matter as in some others we have not followed the customs of Rome. Sanguinarius admitted all his centurions to the patrician class, and since then for over eighteen hundred years only patricians have been appointed centurions.

"But here is Aspar," exclaimed Mallius Lepus, as another officer entered the room. "He has come to relieve me and when he has taken over the gate you and I shall go at once to the home of my uncle, Septimus Favonius."
