 peaches to stand a temperature of eighteen degrees

 this disease may be largely prevented by cultivation and 

 fertilization ; that diseased trees may be so treated as to 

 recover and produce good fruit ; that there is no royal 

 highway to success in the cultivation of this fruit, but 

 that eternal vigilance is the price of an abundance of 

 Peaches.
