utes. This emulsion is valuable at all seasons; in 

 winter for scale insects, in summer for plant lice, 

 thrips, etc. For use, dilute according to what you 

 intend to spray. Two or three tablespoonfuls in 

 a pail of water will be quite strong enough for a 

 first application on roses, but a dilution four times 

 this size will be none too strong when you intend 

 to swab your scale-infested trees. 



In all cases be sure to begin your work as

 the mischief is half done and your enemy well

In spite of all preventives the San Jose scale has 

 invaded nearly all the states of the Union. It will 

 be advisable, therefore, to give you a formula for 

 contending with this formidable pest. At present 

 we have no better method of treatment than that 

 which is called the lime, sulphur and soda mixture. 

 While different strengths of this formula have been 

 used, the following seems to be most satisfactory : 



Sulphur 17 lbs. 



Caustic Soda 3 lbs. 



Lime 33 lbs. 



Water One barrel
