"If you can propose a better candidate for the girl, I—" he paused, looking intently at the letter—"I shall consider him," he added, presently.

"She is beautiful," his daughter whispered. "I know one who will give to the state many thousand aurei."

"No need of hurry. The young Vergilius will give what is better than money, and then—"

The emperor paused again.

"And then?" it was the inquiry of Julia.

"He will forget her and she will grow weary and yield. There's time enough, and time"—he took a little mirror from the table and looked down upon it—"can accomplish many things," he added. "It will have the assistance of fame and honor and new faces. Now go, I beg of you, and leave me to my work."

A delegation of Jews—petty merchants of the Trastevere—were leaving as Vergilius entered. The emperor, now alone save for his young caller, rose and gave him a sprig of laurel.

"Sit here," said he, resuming his seat and pausing for a little to study a sheet of vellum in his hands. He continued, without raising his eyes: "I have another test for you, my fair son. You shall be assistant procurator in Jerusalem, with rank of tribune. It may be you shall have command of the castle. Three days from now take the south road with Manius and a troop of horse. This court of Herod—of course, I am speaking kindly, my dear Vergilius—but, you may know, it is a place of mysteries, and there are many things I do not need to say to you."

The old emperor, leaning forward, touched the arm of the young man and gave him a cunning glance.

"A cipher," he added, passing the sheet of vellum. "It will be known to you and to me only. You will understand what I wish to know. You shall have command of a cohort."
