which scheme appear again in one (8320 of 1903) granted to the StirHng 

 Boiler Co. This scheme is shown diagrammaticall}- in Fig. 283. Bagasse 

 direct from the mill is delivered to an elevator, which in turn discharges 

 to a scraper carrier, a, running in a direction at light angles to the furnaces.

cairier, over each shoot being a sliding trap door controlled from below, 

 whereby bagasse may be directed to the shoot, whence it gravitates to the 

 furnace. The actual feeding to the furnace is often effected b}^ a rotating 

 chum, d, on which are placed longitudinal projections, e, shown on an 

 enlarged scale in the right-hand sketch. In this design the door, /, auto- 

 matically closes when the hopper is empty. 



Two lay-outs of furnaces are general. In one the\' are arranged in two 

 lines between which is located a platform, on to which surplus bagasse ma\'

be discharged through trap doors, and which serves as storage room. Other- 

 wise the carrier may be extended be\-ond the line of the furnaces, and ma\' 

 discharge any surplus to a shed there located. In this case a return carrier 

 is provided to deliver the surplus back to the main carrier when required. 

 The boilers used in connection with bagasse are not specialized types,
