Dissolve the copper sulphate by putting it in a bag of coarse 

 cloth and hanging this in a vessel holding at least 4 gallons, so that 

 it is just covered by the water. Use an earthen or wooden vessel. 

 Shake the lime in an equal amount of water. Then mix the two 

 and add enough water to make 40 gallons. It is then ready for 

 immediate use. If the mixture is to be used on peach foliage it is 

 advisable to add two pounds of Ume in the above forumla. When 

 applied to such plants as carnations or cabbages it will adhere better 

 if about a pound of hard soap be dissolved in hot water and added 

 to the mixture. For rots, moulds, mildews, and all fungous diseases.
