 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-

 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
