From the finishing departments the hats are sent to the floor belowwhere they are passed upon by an inspector and then to the curlingmachines shown in Fig. i. In these an electrically-heated revolvingdisc curls the edge of the brim, the heaters almost entirely surround-ing the disc. It needs no argument to show the decided advantage.

In a large room at the other end of this floor 200 girl operativessew the various trimmings on the hats, all the sewing machines beingelectrically driven. In the flanging room on the first floor twentyflanging bags are used for giving the brim its final shape. Thesebags, which are filled with sand, are at present heated externally onsteam tables, but they will probably be heated internally by meansof electric heaters in the near future. Fifteen additional electric handirons are used by the flanging bag operators, shown at work in Fig. 4. The power house, a pretentious brick structure, occupying a plotSO ft. by gs ft., on the companys spacious site, is divided by a heavyfire wall in two sections. In the one are located four Coatesvillehorizontal t
