I found from my experiments * of last year and the 
year before that the injury which London purple 
usually does to foliage can be almost wholly pre¬ 
vented by the addition of a small amount of quick 
lime to the water, enough to make it appear quite 
milky when stirred. 
Strength to Apply .—Whether London purple 
or Paris green is employed I would recommend 
that it be used in the proportion of one pound to 
160 gallons. If London purple is used, I would 
recommend the addition of the lime as mentioned 
above. If a second application is made, do not use 
stronger than one pound to 200 gallons. 
The liquid should be stirred frequently, 
especially if Paris green is used, to keep the poison 
well mixed through it. 
Time to Apply .—It is alomst universally recom¬ 
mended that spraying should take place as soon as 
the flowers fall. I am satisfied that in case of early 
varieties, there are two or three weeks, at least, 
after the flowers fall before the worms begin to eat 
into the fruit. 
I found ** in 1889 that Duchess apple trees 
dropped their bloom fully one month before the 
worms entered the fruit. 
As the calyx closes very much after the apple 
begins to form, so that less poison would be retained 
there, and, as the apples soon turn downward on
