Solutions Recommended. 



Copper Sulphate Solution. 



Copper sulphate • i pound. 



Water 20 gallons. 



To be used only before the buds burst, and never to be applied on the 

 foliage. When applied to peach trees, use 25 gallons of water instead of 20 

 gallons. 



Bordeaux Mixture. 



Copper sulphate 5 pounds. 



Lime (fresh) • • 4 pounds. 



Water 4° gallons. 



Prof. Bailey advises a stock solu- 

 tion of copper sulphate, in case of 

 large orchards, as follows : A simple 

 method is to dissolve 40 or 50 

 pounds of the sulphate in as many 

 gallons of water, pulverizing the 

 material and hanging it in a coffee- 

 sack in the top of the barrel. A 

 gallon of water, therefore, means a 

 pound of sulphate. The lime may 

 also be slaked and kept in readiness 

 for use. Slake it into the creamy 

 condition familiar to masons, cover ij 



lightly with water, and then close 

 the box or vessel to prevent the ^m^^f ' -^^^' 



water from evaporating. When l^ffmf ^ 'x^«"«f«%

Now add the lime, and then add 

 enough water to complete the for- 

 mula. 



Suspend the copper sulphate in 

 five gallons of water. This may be Fig. 947.— Thk Spkaymotkk. 



done by putting it in a bag of coarse 



material and hanging it so as to be covered by the water. Slake the lime in 

 about the same quantity of water. Then mix the two and add the remaider of 

 the 40 gallons of water. Warm water will dissolve the copper sulphate more 

 readily than cold water. If the lime is at all dirty, strain the lime solution. 

 Use wooden vessels.
