ator's hands, the instrument is not so fatiguing. The 

 workmen who are entrusted with this operation carry 

 with them a small stock of sulphur from five to six 

 pounds in a linen bag, fastened in front of them. 

 This bag [Fig. 121] is thirteen inches wide at the bot- 

 tom, only eight at the top, and eleven inches high. It 

 is provided at one of its lower angles with a conical tin 

 nozzle, C, closed by a cork stopper, and intended to 

 introduce the sulphur into the bellows. The peculiar 

 construction of the nozzle of this bellows allows the 

 jet of sulphur to be sprinkled with ease in all directions 

 up and down, and from side to side. The cost of 

 this instrument, at Bordeaux, is fifty or seventy cents, 

 with the bag. 



Other apparatus have been constructed on the same 

 principles. But it is objected to them, as well as to M. 

 de la Vergne's bellows, that the sulphur comes in con- 

 tact with the leather of the bellows, which very soon 

 destroys it. A manufacturer of Beziers has succeeded 

 in overcoming this objection, while retaining the ad- 

 vantages of M. de la Vergne's bellows. 



[The distinguished vine-grower, G. W. Campbell, of Del- 

 aware, Ohio, has produced an implement for the purpose of 

 dusting his vines, that has some advantages, and may easily be 

 made by any one who desires to use the sulphur, or other dry 

 pulverulent substances, as a remedy against mildew,. 



Mr. Campbell writes that he can not give the expense of 

 this bellows, because he made it himself, and kept no account 

 of the cost of materials, nor of the time spent in its construc- 

 tion. He says he finds it very convenient and effective, and 

 that he can throw a cloud of sulphur and quicklime through
