"That is true," answered Zorzi.

"Yes. I therefore judge that you are one of those unusual beings whom God has sent into the world to be of use to their fellow-creatures instead of a hindrance. For you possess the power of holding your tongue, which I had almost believed to be extinct in the human race. I am going to send you on an errand to Venice, to Jacopo Cantarini. If I sent any one from my house, all Murano would know it to-morrow morning, but I wish no one here to guess where you have been."

"No one shall see me," answered Zorzi. "Tell me only where I am to go."

"You know Venice well by this time. You must have often passed the house of the Agnus Dei."

"By the Baker's Bridge?"

"Yes. Go there alone, to-night and ask for Messer Jacopo; and if the porter inquires your business, say that you have a message and a token from a certain Angelo. When you are admitted and are alone with Messer Jacopo, tell him from me to go and stand by the second pillar on the left in Saint Mark's, on Sunday next, an hour before noon, until he sees me; and within a week after that, he shall have the answer; and bid him be silent, if he would succeed."

"Is that all, sir?"

"That is all. If he gives you any message in answer, deliver it to me to-morrow, when my daughter is not here."

"And the token?" inquired Zorzi.

"This glass seal, of which he already has an impression in wax, in case he should doubt you."
