"Do," said Castor, as earnestly as if he had been promised some pleasure. "What a merry, good-for-nothing set they are!-Dorothea will bring the girl at the appointed hour. Everything is arranged."

Whereupon he danced out of the room, singing a tune.

"An invaluable creature!" said the Syrian, with an admiring glance.

"A better one spoiled," said Serapion. "He has the very highest gifts, but is utterly devoid of conscience to set a limit to his excesses. How should he have one? His father was one of a troupe of Ephesian pantomimists, and his mother a golden-haired Cyprian dancer. But he knows every corner of Alexandria—and then, what a memory! What an actor he would have made! Without even a change of dress, merely by a grimace, he at once becomes an old man, an idiot, or a philosopher."

"And what a genius for intrigue!" Annianus went on enthusiastically. "As soon as he saw the portrait of Korinna he knew that he had seen her double among the Christians on the other side of the lake. This morning he tracked her out, and now she is caught in the snare. And how sharp of him to make Dorothea bring her here!"

"I told him to do that, and use the name of Bishop Demetrius," observed the Magian. "She would not have come with a stranger, and Dorothea must be known to her in the meetings of their congregation."

CHAPTER IX.

While this conversation was taking place, Melissa and her companion had reached the shore of the lake, the large inland sea which washed the southern side of the city and afforded anchorage for the Nile-boats. The ferry-boat which would convey them to the gardens of Polybius started from the Agathodaemon Canal, an enlarged branch of the Nile, which connected the lake with the royal harbor and the Mediterranean; they had, therefore, to walk some distance along the shore.

The setting sun shot slanting rays on the glittering surface of the glassy waters in which the numberless masts of the Nile-boats were mirrored.

Vessels large and small, with white or gayly-painted lateen sails gleaming in the evening glow, large galleys, light skiffs, and restless, skimming pleasure-boats, were flitting to and fro; and among them, like loaded wagons among chariots and horsemen, the low corn-barges scarcely seemed to move, piled as they were with pyramids of straw and grain as high as a house.
