At the farther end of the shop, a worm-eaten wooden staircase led to the two upper floors which were in turn surmounted by an attic. The house, backing against two adjoining houses, had no depth and derived all its light from the front and side windows. Each floor had two small chambers only, lighted by single windows, one looking out on the rue de la Cite, the other on the rue de la Vieille-Poste. In the middle-ages no artisan was better lodged. The house had evidently belonged in those times to makers of halberds and battle-axes, armorers in short, artificers whose work was not injured by exposure to the open air; for it was impossible to see clearly within, unless the iron shutters were raised from each side of the building; where were also two doors, one on either side of the corner pillar, as may be seen in many shops at the corners of streets. From the sill of each door--of fine stone worn by the tread of centuries--a low wall about three feet high began; in this wall was a groove or slot, repeated above in the beam by which the wall of each facade was supported. From time immemorial the heavy shutters had been rolled along these grooves, held there by enormous iron bars, while the doors were closed and secured in the same manner; so that these merchants and artificers could bar themselves into their houses as into a fortress. Examining the interior, which, during the first twenty years of this century, was encumbered with old iron and brass, tires of wheels, springs, bells, anything in short which the destruction of buildings afforded of old metals, persons interested in the relics of the old town noticed signs of the flue of a forge, shown by a long trail of soot,--a minor detail which confirmed the conjecture of archaeologists as to the original use to which the building was put. On the first floor (above the ground-floor) was one room and the kitchen; on the floor above that were two bedrooms. The garret was used to put away articles more choice and delicate than those that lay pell-mell about the shop. This house, hired in the first instance, was subsequently bought by a man named Sauviat, a hawker or peddler who, from 1786 to 1793, travelled the country over a radius of a hundred and fifty miles around Auvergne, exchanging crockery of a common kind, plates, dishes, glasses,--in short, the necessary articles of the poorest households,--for old iron, brass, and lead, or any metal under any shape it might lurk in. The Auvergnat would give, for instance, a brown earthenware saucepan worth two sous for a pound of lead, two pounds of iron, a broken spade or hoe or a cracked kettle; and being invariably the judge of his own cause, he did the weighing.
