On the sixteenth day of my captivity, Sheffield's negro appeared on the scene, evidently bringing disquieting news for my jailer. He carried a hamper into the adjoining chamber, and there the two conversed in a lingo which I did not understand, but from the tone of their voices I judged that they were hurried, and in perturbation of mind. Now one and now the other went out, and once I heard a great crash overhead. Finally, the negro brought in an iron ball of fifty or sixty pounds' weight, attached by bar and chain to a ring, which Boswell locked on my right ankle, otherwise releasing me entirely. The pair kept their eyes on me, and their weapons handy, when this had been done, but I was not so foolhardy as to attack them. In truth, a great hope had come to me that they meant to leave me alone awhile, and I waited to see whether they would deprive me of the means of deliverance. After a good deal of gibberish had passed between them, and the Moor had done various errands at Boswell's command, both went out together, locking and barring the door in the corridor, and then the outer door behind them. I picked up the ball, which I could carry in the crook of my arm, lighted a lamp which had been left on the table, and made a tour of inspection, rejoicing to be able to move about, my limbs being stiff and feeble by long constraint. As I had imagined, the negro had brought a store of food. I found bread, salt-beef, tongue, a couple of pasties, several bottles of burgundy, a jar of aqua vitæ, but no water. But I had no great concern about meat or drink. It was more to my purpose that there were eight moderate-sized faggots of sticks, a pile of turves, and a dozen largish logs. These would suffice. I shouted for joy to find a small hatchet, but was disappointed in searching for oil: the jar was empty. My survey taken, I made up the fire, and put my iron ball at the back of it, so that the links of the chain connecting ball and bar might get the full benefit of the heat, and as soon as one grew red, I prised it open with the head of the hatchet. Fire had freed me from a weight, and provided me with a missile, which, if well thrown, would disable an enemy. I had no means of ridding myself of the bar, much though it would be in my way in my next effort, which was to explore the chimney. I removed the fire from the hearth, and had it well blazing in the middle of the floor, before attempting the chimney, for on fire I must now chiefly depend for my liberation.
