phide of potassium, but if a spray is found necessary 

 it will be better to use the Bordeaux mixture, which 

 for our purpose should be made as follows : Copper 

 sulphate, five pounds ; lime, five pounds ; water, forty 

 gallons. A very weak solution of soft soap used as a 

 spray is also beneficial. 



We give below the two latest approved sprays, the 

 first recipe comes from England and is vouched for 

 by William Payne, F. L. S., Honorable Secretary of 

 the National Rose Society, and a famous rosarian; 

 the second from a skillful rose grower of the 

 United States. Both are good. 



"Boil two pounds of soft soap in two gallons of 

 water; while still boiling and immediately after it 

 has been removed from the fire add half a pint of 

 paraffine oil and a quarter pound of sulphur. When 

 using add half a pint of this solution to a gallon of 

 water, soft water is best, and apply as a spray." 



"Shave up a bar of ivory soap, or any kind which 

 contains no free alkali, and dissolve in a pail of boil- 

 ing water. When dissolved, dilute with five pails 

 of cold water. This does not need washing off again 

 as the thin coating is a preventive as well as a cura- 

 tive. It will also kill all kinds of aphids, or green 

 fly, as well as red spider on violets."
