pounds of lime, and add enough water to make 40 

 gallons of this solution also. With care these solu- 

 tions will keep for some time; if they stand for sev- 

 eral weeks they become considerably concentrated 

 through evaporation of the water. 



To use these stock 

 solutions in making up a 

 barrel of bordeaux for 

 spraying take 4 gallons 

 of the copper sulphate 

 solution and dilute it to 

 approximately 25 gallons. 

 Then take 4 gallons of 

 the lime solution and 

 dilute it in another bar- 

 rel making approximately 

 25 gallons. Then pour 

 the copper sulphate solu- 

 tion into the lime solution 

 as before directed, stirring 

 thoroughly. 



BORDEAUX INJURY AT * , , , 



No matter how the bor- 

 deaux mixture is made it should be strained before 

 using. To do this put it through cheesecloth as it 

 goes into the spray tank. 



In making up large quantities of bordeaux a great 

 amount of labor can be saved by a convenient arrange- 

 ment of barrels or tanks. The usual way is to build 

 a platform, preferably in two stories, as shown in the 

 picture, page 133. The stock solutions are made up 

 in tubs, barrels or tanks on the upper platform. They 

 are also ladled out and diluted on this upper stage. 

 They are then allowed to run together into a trough 

 conducting them to a barrel on the lower platform.
