PLATE XIV 



ACCESSORIES 



Fig. 1. Two types of the Worthley nozzle, used on many of the solid- 

 stream sprayers of the New England states. The extreme tip is removable 

 and may be had in assorted sizes having bores of five-sixteenths, one-fourth, 

 three-sixteenths and one-eighth inch. The larger the aperture, the greater the 

 capacity and the greater the height of spray possible to throw. 



Fig. 2. The M. A. C. spreader sometimes used in connection with the 

 Worthley tip. The pin A centers the stream rushing through aperture C and 

 breaks it up. By means of the handle B, the pin A may be thrown to one side 

 and thus permit solid stream work. The M. A. C. spreader is now displaced 

 in a large measure by another type which spreads the solid stream by deflecting 

 it. Spreaders are necessary for breaking up the solid stream when spraying 

 shrubbery and the lower parts of tall trees. 



Fig. 3. An arsenate of lead mixer. When paste arsenate of lead is used, 

 as a rule it is necessary to mechanically break it up. Various mixers are used, 

 this being one of the churn type.
