he came down to the boat. "I have been in a fever ever since I lost sight of you. Have you succeeded?"

"I have found out that there is certainly a plot of some sort being got up, and I know some of those concerned in it, but I could hear nothing that went on. Still, I have succeeded better than I expected, and I am well satisfied with the night's work."

"I hope you won't come again, Messer Francisco. In the first place, you may not always have the fortune to get away unseen. In the next place, it is a dangerous matter to have to do with conspiracies, whichever side you are on. The way to live long in Venice is to make no enemies."

"Yes, I know that, Giuseppi, and I haven't decided yet what to do in the matter."

A quarter of an hour later, their fare returned to the boat. This time they took a long detour, and, entering Venice by one of the many canals, reached the landing place without adventure. The stranger handed Giuseppi a ducat.

"I do not know when I shall want you again; but I will mark the hour, as agreed, on the pillar. Do not fail to go there every afternoon; and even if you don't see it, you might as well come round here at half past ten of a night. I may want you suddenly."

Before going to sleep that night, Francis thought the matter over seriously, and finally concluded that he would have no more to do with it. No doubt, by crossing over to San Nicolo in the daytime, he might be able to loosen a plank at the back of the hut, or to cut so large an opening that he could hear, as well as see, what was going on within; but supposing he discovered that a plot was on hand in favour of the enemies of Venice, such as Padua or Hungary, what was he to do next? At the best, if he denounced it, and the officers of the republic surrounded the hut when the conspirators were gathered there, arrested them, and found upon them, or in their houses, proofs sufficient to condemn them, his own position would not be enviable. He would gain, indeed, the gratitude of the republic; but as for rewards, he had no need of them. On the other hand, he would draw upon himself the enmity of some eight or ten important families, and all their connections and followers, and his life would be placed in imminent danger. They would be all the more bitter against him, inasmuch as the discovery would not have been made by accident, but by an act of deliberate prying into matters which concerned him in no way, he not being a citizen of the republic.

So far his action in the matter had been a mere boyish freak; and now that he saw it was likely to become an affair of grave importance, involving the lives of many persons, he determined to have nothing further to do with it.
