Water 50 gallons.

 large quantities are needed, is by preparing stock sohitions. These 

 are made by dissolving one or two pounds of copper sulphate in 

 each gallon of water, to any amount desired, and similarly with the 

 lime. These .solutions may be kept for considerable lengths of time 

 in their separate containers. Metal containers should not be used 

 for holding them. The copper is best dissolved by placing it in 

 a sack and hanging so it will be suspended just beneath the sur- 

 face of the water over night. If needed in a hurry hot water must 

 be used. 



To prepare Bordeaux from the stock solutions, add three gal- 

 lons of the copper solution to approximately forty-six gallons of 

 water, and then stir in three gallons of lime stock, or a gallon and
