DIAGRAMMATIC DRAWING OF SPARK-DEFLECTOR IN USE ON WESTERN ROADS ; FRONT VIEW 



IN POSITION, AND OUT OF USE. 



should be effective for use in forested 

 areas. The sparks deflected upon such 

 a right of way would expire harmlessly, 

 and even in the seasons of highest wind 

 it would be practically impossible for 

 them to roll far enough to one side to get 

 into the dry brush of the forest without 

 being checked by some obstruction. 



A front elevation of the hood is like 

 a letter T, with a downward curved top 

 bar, the drawings here presented giving 

 a fair idea of it and its use in connection 

 with the stack. It is made of iron, of 



region of the State of New York, where 

 so much depends on the protection of 

 the woods from fire. The deflector may 

 not be as valuable a thing for forest 

 protection as it is to guard the snow- 

 sheds from fire. In short, it is put for- 

 ward as an untried possibility in the use 

 now proposed, but as a suggestion in 

 which there may be some value, even 

 if it serves only to start other minds 

 toward devising some safeguard more 

 effective than spark-arresters alone have 

 proved.
