uted by a tin tube, 3ft. in length or more, and having at its end a 

 flattened circular piece 

 of tin. The blast, after 

 impact on the piece of 

 tin, spreads out in a 

 fan -like shape, and dis- 

 tributes the sulphur or 

 powder evenly in the 

 form of a cloud. The 

 machine, which costs 30 

 francs in France, is 

 easily kept in working 

 order, all that is re- 

 quired is, besides empty- 

 ing the reservoir after 

 using, an occasional 

 oiling of such parts of 

 the lever where friction 

 occurs. 



This sulphurer dis- 

 tributes fungicide or 

 insecticide powders 

 more evenly and in a 

 finer state than the 

 ordinary bellows. 



To produce a similar effect, less powder is distributed ov.er a 

 given area, thus effecting a great economy. 



The powder is applied with more force, and has a better chance 

 of adhering to all the leaves, while the working is easier than in 

 the case of ordinary bellows. 



Simpler and cheaper powder casters are also illustrated, and 

 -consist in the old fashioned but efficacious sulphur bellows, the 

 construction of which is shown in the following diagrams.
