the leaves and the grapes. This contrivance has the dis- 

 advantage of using a great quantity of sulphur (three times 

 more than bellows), and spreads it unevenly. 



2nd. Sulphur bellows (Fig. 145), which is the instrument 

 most used. It is an ordinary bellows without a valve on the 



bottom part and having on the top an 



opening provided with a funnel 0, used for 



filling it with sulphur ; a tube t, provided 



with wire 



gauze, is used 



to direct the 



jet. When 



the instru- 



ment is filled 



and the cork G firmly secured, each movement introduces 

 a certain quantity of air into the bellows, which stirs up the 

 sulphur and expels it at the next motion. The sulphur is 

 spread much more evenly with these tubes. 



3rd. Pensard's sulphuring machine (Fig. 146) is formed 

 of a large tin recipient R, containing from 2J to 3^ gallons 



of powdered sul- 

 phur. A belt b 

 is secured at the 

 back, passing 

 over the shoulder 

 of the operator. 

 The bottom part 

 of the recipient 

 is prolonged by 

 a large rubber 

 tube c, connected

r, surmounted by a cylindrical bellows s, and provided with 

 long tubes t. A spiral spring, secured on the top part of 

 the recipient R and inside the box r, drives the sulphur -in 

 the latter at each motion of the rubber tubes. 



The machine is worked as follows : The operator walks 

 along the rows of vines ; raises and lowers the tube sharply 

 with his right hand at each step, and expels the sulphur 

 from the machine by compressing the bellows with the left 

 hand. The sulphur is thus spread over the vines in fine 

 clouds.
