"With this!" Basterga replied. And for the third time, drawing himself up to his full height, he tapped his brow. "Do you doubt its power?"

For answer Grio shrugged his shoulders, his manner sullen and contemptuous.

"You do?"

"I don't see how it works, Messer Basterga," the veteran muttered. "I say not you have not good wits. You have, I grant it. But the best of wits must have their means and method. It is not by wishing and willing——"

"How know you that?"

"Eh?"

"How know you that?" Basterga repeated with sudden energy, and he shook a massive finger before the other's eyes. "But how know you anything," he continued with disdain, as he dropped the hand again, and turned on his heel, "dolt, imbecile, rudiment that you are? Ay, and blind to boot, for it was but the other day I worked a miracle before you, and you learned nothing from it."

"It is no question of miracles," the other muttered doggedly. "But of how you will persuade the Syndic Blondel to betray Geneva to Savoy!"

"Is it so? Then tell me this: the girl below who smacked your face a month back because you laid a hand upon her wrist, and who would have had you put to the door the same day—how did I tame her? Can you answer me that?"

Grio's face fell remarkably. "No, master," he said, nodding thoughtfully. "I grant it. I cannot. A wilder filly was never handled."
