160 QUINCE CULTURE, 
Dissolve the copper sulphate in one gallon of hot 
water, and in another vessel slake the lime with a gallon 
of water; add the milk of lime slowly to the copper solu- 
tion, stirring constantly, and strain through a sieve or 
coarse gunny sack; finally, add twenty gallons of water, 
and the mixture is ready to be applied with a spraying 
pump. 
Good results are obtained with a mixture of half the 
above strength, which consists in doubling the water, or 
correspondingly diminishing the copper and lime. In 
like manner a one-third strength is often recommended, 
especially for the last sprayings. 
(2) Cupram (the ammoniacal solution of copper car- 
bonate) consists of— 
Carbonate of copper, 5 ounces 
Ammonia water (strength 4 F.), 3 quarts 
Water, 50 gallons 
Wet up the copper carbonate in a quart of water, add 
it to the ammonia, and when completely dissolved dilute 
with water, as needed. 
It is well to use the Bordeaux (1) for the first half of 
the season, beginning as soon as the leaf buds open, and 
spraying the trees at least once each week. During the 
second half of the season, continuing until September, 
the cupram (2) may be used. 
There are so many destructive fungi common to all 
fruit trees, that it is wise to spray all trees of the orchard, 
whether apple, pear or quince. If fruit falls badly it 
should be gathered and destroyed. Let no rot get a 
foothold anywhere. 
For the preparation of this chapter the author has 
drawn largely upon a bulletin* he published a few years 
ago. Some of the cuts have been reproduced here.
