The floor is composed of two pieces of curved sheet-iron, forming at the same time the top of the warm-air chamber of the heater below. These two pieces of sheet-iron leave au opening o between them, w hich extends the whole length of the drying-room, and through which the hot air is introduced, which, after having dried the bottom and dampest part, rises with the vapor it produces toward the ceiling, and descends again to the ventilating-openings, arranged near the floor along the ?whole length of the side-walls, the latter being made hollow and pro- vided with pipes leading to the chimney, which also contains the smoke- l)ipe, as shown in the figures. The linen is arranged outside of the drying-chamber on brass tubes sliding on iron rods extending the whole length of the chamber. These rods and the tubes which they carry are placed at the middle of a nar- row door of the same height as the drying-chamber, which is only opened when the wet linen is put in, or the dry taken out. Each chamber contains 8 rods. They receive, in two charges, 106.
