This machine has the advantage of enabling work to be 

 -done very rapidly ; one man may sulphur about 5 acres in 

 half a day with it. It also saves the sulphur, as the machine 

 is not filled so often (each filling meaning a certain loss) 

 and distributes the sulphur perfectly. 



4th. Vermorers torpedo sulphuring machine (Fig. 147), 

 is a cylindrical tin box, arranged so as to be carried on the 

 back; its shape is very similar to that of the spray-pump used

for sulphate of copper solution. The box contains a sulphur 

 reservoir and bellows worked by a lever; a rubber tube 

 connects the bellows with a long tube, at the end of which 

 is a kind of flat plate spreading the sulphur. 



This machine has the same advantages as Pensard's and is 

 easier to work. 



Three sulphurings are usually applied during the year. 

 The first in May,* at the time of florescence, requires about 

 13 Ibs. of sulphur per acre if the bellows are used; the 

 -second, between the loth and 30th of June,f requires 26 Ibs.; 

 and the third, applied in July,t requires from 30 to 40 Ibs., 

 which makes a total of 70 to 80 Ibs. per acre per annum.
