46 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 



Woodin & Little, 509 and 511, Market street, San Francisco, Cal. The 

 universal spray tip, the only valuable modification of the Riley nozzle 

 that has appeared in this country, is the invention ,of and is manu- 

 factured by J. Orofton and L. D. Green, Walnut Grove, Cal. 



The addresses of the manufacturers of the foreign modifications of 

 the Riley nozzle are as follows : 



The Noel nozzle^ by the firm of Noel, Paris. 



The Vermorel nozzle, by V. Vermorel, Villefranche (Rhone), France. 



Two modifications of the Vermorel nozzle are : 



The Jap\j nozzle, by Japy Freres & Cie, Beaucourt, France, and 



The Albrand nozzle, by M. 0. Albrand, 87 rue dela Republique, Mar- 

 seilles, France. 



The Marseilles nozzle, by L'Avenir Viticole, Marseilles, France. 



In New Zealand the Riley nozzle is manufactured by Kutzuer Bros., 

 of Masterton, who call it the American cyclone nozzle and make it 

 single and in triplets. 



I will call attention here to but one of the most successful of these 

 modifications, which is shown in figure 12. It is known as the Vermorel 

 nozzle, and was devised by a gentleman of that name in France. The

important feature of this nozzle is the pin inserted through its base, 

 bearing on its upper end a point sufficiently small to enter the dis- 

 charge orifice when thrust upward from below. This enables the ope- 

 rator to clean the discharge, when it becomes clogged, and is a great 

 convenience, especially for spraying heavy suspension liquids. 



The Nixon or Climax Nozzle. — This is the invention of Mr, A. H. 

 Nixon, of Dayton, Ohio. Its work is so satisfactory, especially where 

 considerable force is required, as will be generally the case in forest work, 

 that I notice it here. A nipple screws on the distal end of a discharge- 

 pipe, and on its outer end is screwed a brass tube varying in length and 

 diameter according to size of nozzle. The discharge orifice through the 

 nipple regulates the quantity of spray, and nipples with different sized 

 discharge orifices are interchangeable. The stream projected through 

 this nipple strikes a brass screen at the outer end of the tube and is cut 

 into a perfect spray.
