Sprayers. 



double-discharge force pump, mounted on a 

 barrel, it may be said that while they can not 

 do the work as rapidly as the machines of the 

 first class, they are more effective, much 

 cheaper, and far less wasteful of the liquid 

 used. 



To the third 

 class belong the 

 knapsack spray- 

 ers, which are the 

 onl}^ ones neces- 

 sary' to notice in 

 this connection. 

 There is no ques- 

 tion that for all 

 moderately low- 

 growing crops the 

 knapsack sprayer 

 fills every require- 

 ment. In no other 

 machine is the 

 work so absolutel}' 

 at all times under 

 control, it being ; 

 possible to place 

 nearly every drop • 

 of the liquid ex- 

 actly where it i- 

 needed. Knapsack , 

 pumps are no^\ 

 used in many mod- 

 erate sized viuf 

 yards, also ii 

 places where th 

 horse-power ap- • 

 paratus, owing to 

 the nature of the 



land or the manner of cultivation, can not 

 be utilized. 



Many firms throughout the country (as will 

 be seen by referring to the advertising col- 

 umns of agricultural papers) are engaged in 

 the manufacture and sale of the various ma- 

 chines mentioned. 



For applying sulphur various devices are 

 in use. Probal)ly the simplest is that em- 

 ployed by the grape growers of California, 



i. e., a tin can holding about a gallon, pro- 

 vided at the top with a strong, rigid handle, 

 and having the bottom punched full of small 

 holes. Owing to the manner in which the 

 vines are trained, two rows can be treated at

a time by one man. A can containing sul- 

 phur is simply held in each hand and given a 

 slight twist over a vine in each row. This 

 scatters the sulphur over the entire plant and 

 the operator then passes to the next two 

 vines. Of course this plan could not be fol- 

 lowed in the East, owing to the wa^' in which 

 the vines are trained. Various st3'les of sul- 

 phuring bellows have been designed for this 

 work, but it is lieyond the scope of this paper 

 to enter upon a discussion of this class of 

 apparatus. 



CONCLUSIONS. 



In conclusion, the importance of exercising 

 care in making the treatments should again be 

 emphasized. The work if it is worth doing 

 at all is worth doing well ; therefore every 

 precaution should be taken in the prepara- 

 tion and application of the fungicides. With 

 the exercise of judgment there is no reason 

 why the work can not be made a success, and 

 fine, luscious fruit grown where a few years 

 ago such a thing was out of the question.
