hardy trees and shrubs as the Eleagnus angustifoUa and 

 Lonicera iartarica, with liot dry summers and cold winters, 

 it suggests a possibility of extending the American peach- 

 belt farther north. In support of this belief the writer 

 obtained a few peach pits in 1883 from south Bokhara, 

 from which have come such varieties as Bokhara No. 

 3 and No. 10, which have proven fully thirty per cent 

 hardier than any of the old varieties. 



186. Propagation of Plum, Prune, Apricot, and Peach. 

 — These fruits are so nearly allied that they can be all 

 budded or grafted on the same stock. And commercially 

 the peach is often worked on Ohicasa-plum stocks and the 

 plum on peach. The apricot is sometimes grown on 

 apricot-seedling stocks, but far more generally on domestica 

 plum-seedlings. 



I Commercially, the domestica and Japan plums are 

 mainly budded on myrobalan stocks imported or home 

 grown. The apricot is usually budded on its own seedlings 

 or on seedlings of the domestica plums, and it also makes 

 a good tinion with Americana stocks. 



In the prairie States, for reasons given in section (47), 

 Americana stocks are largely used in propagating all 

 plums, prunes, and apricots. In budding on this stock 

 the buds are often inserted the same season the pits are 

 planted (74). 



The summer budding (73) and winter grafting (86) of 

 the plum, prune, and apricot are given in Chapter VII. 



The peach is usually budded on peach-seedlings at the 

 North. The stratified pits (5) are planted early in spring^ 

 given good culture, and budded in August. The tops are 

 cut back the next spring (75) to start growth, which makes 

 a well-branched tree for orchard-planting the first season. 



In California and the South the long seasons permit the 

 early planting of the pits and budding in June. The leaf-
