"Well," pursued the other, in a very low tone, "take this little pot of ointment; and two hours before you have to ride the Sejan horse, go into his stable, make friends with him, and rub his nostrils with the contents. He will be then muzzled, you know. You will find him afterward docile."

"Whom have I to thank for so much interest in me?" demanded Paulus.

"My name is Charicles," replied the stranger hesitatingly, and still speaking almost in a whisper; "and I have the honor of numbering Dionysius of Athens among the best of my friends."

"My mother," returned Paulus, "would, I think, be glad to see you some day soon."

"I shall feel it an honor; but pray excuse me to her to-night," said Charicles. "Tiberius Cæsar knows nothing of my absence, and I had better return at once to Formiæ. I will visit you again."

"But would this ointment injure the horse?" inquired Paulus.

"Not by any means," said Charicles; "it comes from a distant eastern land. It will merely make him sleepy. I have been more than an hour and a half handling the ingredients, and I can hardly keep awake myself. Forgive my hurry—farewell." And the stately Greek made an obeisance as he disappeared.

Paulus remained, holding the pot, which consisted of some kind of porcelain, in his hand, and looking at it, when Thellus exclaimed,

"Why, this laurel hedge is alive!"

In a moment he had sprung through it and returned, dragging in his mighty grasp Lygdus the slave.
