factured by J. J. McGowen of Ithaca, N. Y., satisfies the above conditions. 

 It has a plunger that is adjusted by a set screw and controlled by a stiff 

 steel spring; if in any way the orifice becomes clogged, the force of the 

 water will push out the plunger against the spring, thus allowing the 

 obstruction to pass out through the full-size opening. The size and char- 

 acter of the stream can also be varied at will. The price of this nozzle is 

 two dollars.

Fig. 59.— Myers' Backet Pump. 



The Nixon nozzle (Fig. 61) consists of 

 three parts, of which No. 2 is a nipple 

 with a small perforation at the end, 

 through which a solid stream is thrown, 

 which finally breaks into a fine spray. 

 The cap (No. 8) screws on over the end of 

 the nipple, and has its end covered with 

 fine brass netting which breaks up the 

 stream into a mist-like spray. This nozzle 

 does excellent work on low trees and on 

 bush plants, but it is hardly satisfactory' 

 for use upon trees so tall that they can not 

 be reached with the spray through the 

 netting. Another objection to this nozzle 

 is that it is likely to clog, and yet, as stated 

 above, for many purposes it is an excel- 

 lent nozzle. It retails for one dollar.
