THE BORDEAUX MIXTURE. 



The importance of copper solutions as fungicides having been proved be- 

 yond doubt, we append two formulae for the Bordeaux Mixture, (or Copper 

 Mixture of Gironde), which, in some of its modifications, is used more often 

 than any other. 



THE ORIGINAI, FORMULA. 



(i.) Sulphate of copper, i6 lbs., dissolved in 22 gallons of water. 



(2.) Lime, 30 lbs., " in 6 



When (2) is cool, mix the solution slowly and thoroughly with solution (i). 



A MODIFIED FORMULA. 



(i.) Sulphate of copper, 6 lbs., dissolved in 4 gallons of hot water. 



(2.) Lime, 4 lbs., " in 4 " cold water. 



Mix the two solutions as above, and when desired for use dilute to 22 gal- 

 lons with cold water. The latter mixture is applied (by means of a 

 "sprayer") more readily than the former, is cheaper, and does not endan- 

 ger young leaves.
