"A great many nozzles, owing either to faulty construction or to 

 wear, dribble. In new nozzles this is seldom serious but in old and 

 worn nozzles it frequently gets to be a regular stream. This is not 

 only a waste of liquid but also a great annoyance to the operator as 

 all or part of this waste usually runs down the pole or extension rod 

 on to his hands and arms. It is particularly disagreeable if the mix- 

 ture be caustic. Nozzles will dribble worse with thicker liquids 

 than with those of thinner nature. ^■'- * * Many otherwise good 

 nozzles are deficient in this respect." 



Tests showed that none of the Vermorels dribble, but most of 

 them have a stuffing box at the end of the spindle which may leak if 

 not kept packed. Fan-shaped sprays in a number of nozzles dribbled. 



The best uo^^-clc. — The experiment Station often receives inquiries 

 as to which is the best kind of nozzle to use in spraying. This ques- 

 tion is discussed under the heading of " The Most Desirable Spray,"

Venn Orel nocsles. — In the opinion of the writers the best nozzles 

 for use in fruit plantations are those of the Vermorel type. Manu- 

 facturers have devised several modifications of the A'^ermorel nozzle. 

 One recently introduced makes it possible to change from a solid 

 stream to a fine spray. The modifications adopted in the Spramotor, 

 Goulds' Mistry and Goulds' Large Mistry give a very broad cone- 

 shaped spray and the spray is very fine. The Goulds ]\Iistry throws 

 a finer spray with a low pressure than does the common Vermorel. 

 It is supplied with a cleanout by which solid substances may be re- 

 moved from the piping or from the stem of the nozzle. Goulds' 

 Large Mistry is capable of covering a considerably larger area than 

 do the common Vermorels. It is made with a swivel which permits 

 of throwing the spray in any direction. When two of these nozzles 

 are mounted on a Y the most varied directions may be given to the 

 spray by changing the adjustment of the individual nozzles.
