CHAPTER XI. 



Pumps and Nozzles for Spraying Trees. 



Experience has taught us that tlie most etfective remedies 

 for the extermination of insects injurious to fruit and fruit 

 Fig. 1. trees, especially those belonging to the Cnccidae, 

 are those that can be applied in solution. For 

 the application of such solutions the best 

 method is by a pump and spraying nozzle. I 

 have been frequently asked the question : What 

 kind of pump, nozzle, etc., is the best? The

accompanying illus- 

 trations represent the 

 best apparatus we 

 <^ know of at present. 



I Fig. 1 represents a 



fountain pump. The 

 end of the hose is 

 placed in a barrel or 

 pail containing the 

 fluid. Price, $7.50. 



The fountain pump 

 is designed for gar- 

 den use, and is sold 

 by Baker & Hamil- 

 ton, Sacramento and 

 San Francisco ; and by H. P. Gregory & Co., San Francisco. 

 Fig. 2 represents a pump, known as the "Gould Pump," 

 manufactured by H. P. Gregory & Co., Nos. 2 and 4 California 

 Street, San Francisco. A large numl^er of these pumps are 

 now in use, and give excellent satisfaction, as the working 

 parts are made to resist the chemical action of the disinfect- 

 ants used.
