II. Nozzles of the J'eriiwrcl type arc very numerous, 

 the following beino; the most common: Australian, Bean, 

 Buena, Cyclone. Dewey, Eureka, Handy, Imperial, San Jose, 

 Spray-motor, Vapor-Mist, Vermorel. They produce a fine 

 conical spray and are largely used for spraying fruit trees 

 and vegetable plants. Some of them are supplied with a de- 

 gorger for removing solid substances from the opening of the 

 nozzle. With the Spray-motor, the Vapor-Mist and the Eu- 

 reka the degorger may be operated by simply pressing the noz- 

 zle against a branch, while with the Vermorel it usually be- 

 comes necessary to lower the extension rod and operate the 

 degorger by hand. On account of the small opening in this 

 type of nozzle it frequently becomes clogged and in order to 

 produce sufficient spray, two or more nozzles are necessary. 



III. The third type is represented by the Atomic, the 

 Friend, the Mistry, the Mistry Jr., the Power, the Simplex 

 and the Tiger. These are very similar to those of the Ver- 

 morel type, differing chiefly in having a larger chamber, and 

 a larger opening and in their abiHty to produce a larger spray. 

 On account of the larger opening, they cause less trouble by 

 clogging. Discs with different sized openings, specially adapt- 

 ed to the various conditions, are usually furnished with each 

 nozzle. Brown's Atomic nozzle is fitted with a device for reg- 

 ulating the size of the opening, making it possible to change 

 from a fine spray to a solid stream. Other nozzles of this 

 type are equipped with a degorger for clearing the opening, 

 but when care is taken in keeping the solution free from 

 coarse material, such a device is not necessary. As a rule 

 these degorgers make the nozzle unnecessarily heavy and 

 often cause much annoyance by getting caught among the 

 branches. The Friend nozzle is made in two styles. One is 

 constructed so as to throw a spray at a slight angle. This is 

 undoubtedly a great convenience when spraying fruit trees 

 and also when spraying beneath low-growing plants. The 

 Mistry may be adjusted to spray at any angle but is objec- 

 tionable on account of its tendency to leak at the swivel. 



A nozzle like the Friend angle nozzle is well adapted to
