spray, slake two pounds of lime and stir it into forty gallons 
of water, adding a pint of the mixture from the jug.”

]50RI)KAL'X MIXTURE AND THE ARSENITES. 
Bordeaux mixture js a fungicide and is the substance 
most often used for the destruction of fungi that attack the 
the surface of plants. It has also been found to be of value 
for use against flea-beetles and the writer also demonstrated 
its value a number of years ago as a medium in which to 
spray Paris green or London purple. These poisons can be 
used very strong in this mixture without injury to foliage 
and they do not, in the least, lessen its effects as a fungicide. 
Such a mixture would destroy both insects and fungi with 
one application. 
The Bordeaux mixture may be prepared as follows: 
Take of 
Cojiper sulphate 6 pounds. 
Quicklime 4 pounds. 
Water ' 45 gallons. 
Dissolve the copper sulphate in a gallon of hot water, 
slake the lime in another gallon of water and then add the 
milk of lime slowly to the copper sulphate solution while the 
latter is being constantly stirred, d'hen add 43 gallons of 
water. 
’ If insects are to be killed at the same time, add to the 
above quantity of Bordeaux mixture, one-third pound of 
London purple or Paris green.
