100 Lessons in Fruit Growing. 



15. The cherry thrives best on a warm, dry, sandy or 

 gravelly loam (108). 



16. Seedlings of the bird and mahaleb cherries are 

 chiefly used as stocks for the sweet and sour cherries. The 

 mahaleb is the more resistant to cold of the two (109). 



17. The peach tree is less resistant to cold than the 

 plum or cherry, and its flower buds are more readily excited 

 by warm weather in winter. Its cultural range is there- 

 fore comparatively narrow (112, 113), 



18. The peach fruits on wood of the preceding season, 

 and not from spurs (114). It is propagated by budding on 

 peach seedlings (115). 



19. Peach orchards are commonly most enduring on fer- 

 tile, well-drained, clay loams (116). 



20. The peach tree should be pruned to develop an 

 abundance of new wood near the trunk (118). 



21. Peaches should be picked when they are full-grown 

 and have begun to assume their mature color (119). 



22. The peach is much subject to disease. The yellows, 

 rosette and "little peach" are three serious diseases for 

 which no remedies are known. The only preventive meas- 

 ure practiced is destruction of the affected trees. The leaf 

 curl is held in check by spraying with Bordeaux mixture 

 (122-125). 



23. The apricot resembles the peach in most characters 

 that have a bearing on culture. Its cultural range is nar- 

 rower than that of the peach (126-127). 



SUGGESTIONS FOR LABORATOEY WORK. 



1. Study the insects and diseases affecting the pear, 

 quince and stone fruits, from the trees and fruits, so far as 

 practicable, and apply the preventive measures recom- 

 mended.
