The landlord came back presently, his face black as thunder. "It has got the staggers," he said resentfully.

"It has got the devil," the stranger answered coldly. "I knew it was in the house when I entered. If you doubt me, I will prove it."

"Ay?" said the landlord stubbornly.

The man in black went to his saddle-bag, which had been brought up and laid in a corner, and took out a shallow glass bowl, curiously embossed with a cross and some mystic symbols. "Go to the church there," he said, "and fill this with holy water."

The host took it unwillingly, and went on his strange errand. While he was away the astrologer opened the window, and looked out idly. When he saw the other returning, he gave the order "Lead out the horse."

There was a brief delay, but presently two stablemen, with a little posse of wondering attendants, partly urged and partly led out a handsome grey horse. The poor animal trembled and hung its head, but with some difficulty was brought under the window. Now and again a sharp spasm convulsed its limbs, and scattered the spectators right and left.

Solomon Nôtredame leaned out of the window. In his left hand he held the bowl, in his right a small brush. "If this beast is sick with any earthly sickness," he cried in a deep solemn voice, audible across the square, "or with such as earthly skill can cure, then let this holy water do it no harm, but refresh it. But if it be possessed by the devil, and given up to the powers of darkness and to the enemy of man for ever and ever to do his will and pleasure, then let these drops burn and consume it as with fire. Amen! Amen!"

With the last word he sprinkled the horse. The effect was magical. The animal reared up, as if it had been furiously spurred, and plunged so violently that the men who held it were dragged this way and that. The crowd fled every way; but not so quickly but that a hundred eyes had seen the horse smoke where the water fell on it. Moreover, when they cautiously approached it, the hair in two or three places was found to be burned off!

The magician turned gravely from the window. "I wish to eat," he said.

None of the servants, however, would come into the room or serve him, and the landlord, trembling, set the board with his own hands and waited on him. Mine host had begun by doubting and suspecting, but, simple man! his scepticism was not proof against the holy water trial and his wife's terror. By-and-by, with a sidelong glance at his guest, he faltered the question: What should he do with the horse?
