kept our bushes clean nearly the whole season, although the 

 young worms were very numerous. 



Among nozzles suitable for spraying trees, we have used an 

 ordinary hose-pipe and rose, the Gem Graduating Spray, Boss, 

 Crown, Lowell, Magic, Mistic, and Nixon's Nos. 3, 4, and 5. 

 We have also made a test of these under 20 lbs. pressure, having 

 the following points in mind : fineness and evenness of spray, 

 breadth of spray, force, and convenience of manipulation. It 

 seemed to us that for large trees, the Gem, Mistic, and Boss an- 

 swered the requirements best. 

 For small trees, the Nixon's 

 are best. 



We still need a nozzle for 

 large trees which can be grad- 

 uated without stopping the 

 puriip or lowering the nozzle, 

 and which will not clog. Fig. 

 8 represents a nozzle which we 

 have made to meet these re- 

 quirements. Like our bush 

 nozzle, the essential feature of 

 this is the compressing of the 

 end of a hose. In ordinary 

 hose the webbing soon becomes 

 loose at the end and causes the 

 spray to split, so that we were 

 obliged to substitute a strong 

 pure rubber tube, to the end of 

 which the hose is attached. 

 This tube, E, is shoved through 

 and cut off a trifle as soon as the 

 end becomes worn . The nozzle 

 is secured to a stick of the re- 

 quired length, by which the 

 operator elevates it toward the

tree, and the spray is regulated at will by means of the cord attached 

 to the lever, F. A set-screw in front of the lever adjusts a clamp 

 which holds the tube in place. All things considered, this is the 

 best nozzle for spraying large trees which we have tried. The 

 adjustment of the rubber tube is somewhat perplexing, however, 

 but this can no doubt soon be remedied by the substitution of a 

 rubber thimble made for the purpose. L. H. BAILEY.
