severing care, there is increasing encourage- 

 ment. Let no one be deceived, however, into 

 thinking this is work which will need little 

 thought or attention. The destruction now 

 caused by insects and fungi is so serious that 

 only by systematic use of the various rem- 

 edies as required can we expect satisfactory 

 returns. 



Spraying with poisons for insects which 

 feed upon the foliage, or with caustics and 

 offensive solutions for those which suck the 

 juices, and with chemicals which will destroy 

 low forms of vegetable life without injury to 

 the higher forms, is the simple rule for the 

 treatment of the great majority of cases. In 

 order that the material may be economized 

 and extend and be diffused as far as possible, 

 it is important to use a cyclone nozzle, which 

 will divide the stream into a fine mist. There 

 are several patents offered which are so made 

 that they can be quickly cleaned when ob- 

 structed by lime or other particles. The im- 

 proved Vermorel is used by the United States 

 Department of Agriculture. This can be at- 

 tached to a Eureka sprayer which is carried 

 on the back of the operator, who can pump 

 and also direct the spray at the same time. 

 There may be other devices equally as good.
