PREPARATION AND USE OF BORDEAUX MIXTURE. 



The character of Bordeaux mixture varies greatly, according 

 to the way in which it is made. The following method of per- 

 paring it, now very generally employed throughout the coun-

 4 pounds quicklime (stone lime.) 

 4 pounds copper sulphate (blue vitriol). 

 50 gallons water.
