Intelligence In application and good judgment are the two 

 great principles that insure success in spraying. 



Professor Smith, Entomologist of Ne-w Jersey, says in one 

 of his reports that he made a very interesting observation in 

 an application of KIL-o-SCALE made by a local nurseryman. 

 We quote him as follows: "It proved to be an excellent illus- 

 tration of lion- spraTin^ is often done. The object seemed to 

 be to set over the greatest number of trees in the least pos- 

 sible time, and whenever the spraying rod has been over as

many inovements as might reasonably be required for a eov- 

 ering, the ^vork was considered finished. Sueli ^vork is bound 

 to be unsnceessful* and it is regretfully concluded that much 

 of the work done is of the same general character." 



In spraying for San Jose scale both fall and spring appli- 

 cations are very advisable; but in cases where it is impossible 

 to do it twice, then the spring of the year is preferable. The 

 advantage in spraying twice lies in the fact that the scale that 

 are missed in the first spraying can killofi in the second.

EXPLA.VITIOX.— Whenever an Aster- 

 isk (*) is used it cautions against spray- 

 ing- with poisons while the plants are in 

 blossoms. A Dagger (f) indicates that 

 there is danger of making an applicatien 

 within three weeks of the time the fruit 

 is to be used as food.
