I felt it, in the darkness. It fitted closely, and was heavy. I could not begin to slip it. A ring was attached to it, and a chain was attached to this ring, running, as I discovered, to another ring, fastened to a plate, apparently bolted into the wall.

My wrists were also confined. I wore metal cuffs, joined by some inches of chain. My ankles, by metal anklets, linked by a bit of chain, were similarly secured.

I crouched in the darkness, terrified.

I felt the collar again. It was closed by means of a heavy lock, part of the collar itself. It would thus, presumably, respond to a key. The cuffs and anklets, on the other hand, were quite different. They had apparently been simply closed about my limbs, closed by some considerable force, perhaps that of a machine, or even, perhaps unthinkably primitive though it might seem, by the blows of a hammer on an anvil. They were of flat heavy strap like metal. They had no hinges. Perhaps they had begun as partly opened circles into which my limbs had been thrust, circles which had then been, by some means, closed about my limbs, confining them. They did not have hinges. There was no sign of a place for the insertion of a key. They clasped me well. It would be impossible to remove them without tools. I could thus be freed from the collar, and the wall, quite simply by means of the key. I could not be rid so simply, of course, of my other bonds. This suggested to me that I might be, in the near future, removed from this place, but that no similar indulgence might be expected with respect to my other bonds. I wondered who held the key to my collar. I suspected that it might be merely one of many keys, or, perhaps, a key to many similar locks.
