voyages there was fixed an instrument about a foot long, and this consisted of a hand moving along a graduated scale. I made sure (so far as my very brief opportunity of observation permitted) that this hand did not move by clockwork, but I was quite unable to discover by what power it did move.
I told Jack very briefly about the light I had seen last night, and then we held a brief conference before we parted.
"Jack," said I, "you thought yesterday that Signor Niccolo had given his man instructions either to kill you or to put you in the way of killing yourself?"
"Yes," he said, "under certain circumstances. If I attempt to make my escape the fellow is undoubtedly under orders to compass my death. But not otherwise; certainly not at present. And I need not say that I am not going to attempt my escape without you. If you and I agree to force a crisis, good and well; then we shall both run the risk of our lives. But you seem to think, and I am disposed to agree with you, that we had better for the present keep on the watch and let things take their course. Very well, then, I shall not be in any special danger to-morrow."
"Why do you think so?"
