Instead of a lock, the chest was fastened by a lengthy thong of oxhide, which now lay in a coil on the floor. Bound round and round, twisted and intertangled, and finally tied with a special and secret knot (the ends being concealed), the thong of leather secured the contents of the chest from prying eyes or thievish hands. With axe or knife, of course, the knot might easily have been severed, but no one could obtain access to the room except the retainers of the house, and which of them, even if unfaithful, would dare to employ such means in view of the certain punishment that must follow? It would occupy hours to undo the knot, and then it could not be tied again in exactly the same fashion, so that the real use of the thong was to assure the owner that his treasures had not been interfered with in his absence. Such locks as were made were of the clumsiest construction. They were not so difficult to pick as the thong to untie, and their expense, or rather the difficulty of getting a workman who could manufacture them, confined their use to the heads of great houses. The Baron's chest was locked, and his alone, in the dwelling. Besides the parchments which were nearest the top, as most in use, there were three books, much worn and decayed, which had been preserved, more by accident than by care, from the libraries of the ancients. One was an abridged history of Rome, the other a similar account of English history, the third a primer of science or knowledge; all three, indeed, being books which, among the ancients, were used for teaching children, and which, by the men of those days, would have been cast aside with contempt. Exposed for years in decaying houses, rain and mildew had spotted and stained their pages; the covers had rotted away these hundred years, and were now supplied by a broad sheet of limp leather with wide margins far overlapping the edges; many of the pages were quite gone, and others torn by careless handling. The abridgment of Roman history had been scorched by a forest fire, and the charred edges of the leaves had dropped away in semicircular holes. Yet, by pondering over these, Felix had, as it were, reconstructed much of the knowledge which was the common (and therefore unvalued) possession of all when they were printed.
