370 On the Management of Fruit Trees intended for Forcing. 



nearly warm enough to have ripened it at all, if the plants 

 had previously grown in the open air. 



Having raised many varieties of the Peach from seed in 

 the year 1813, I felt anxious to secure the existence of each 

 variety till I could ascertain its merits ; and with this view, I 

 obtained a duplicate of each by inserting a bud from every 

 seedling plant into a stock, which I placed in the forcing- 

 house. Late in the autumn of the year 1815, some of the 

 young trees, which had been obtained from these buds, were 

 removed from the forcing-house, in which their wood had 

 become most perfectly well ripened, in the preceding summer, 

 to the open air, and were placed as closely, as could conve- 

 niently be done, to the seedling trees of the same varieties, 

 which had grown wholly in the open air : and thus circum- 

 stanced, the blossoms of the trees, which had been removed 

 from the forcing-house, unfolded nine days earlier, and their 

 fruit ripened three weeks earlier, than that upon the other 

 trees of the same varieties. 



The confinement of the roots to pots, and possibly, to a 

 small extent, the influence of the stock (for the Peach trees 

 in the pots grew upon Apricot shoots), may have somewhat 

 accelerated the maturity of the fruit, in the experiment last 

 mentioned ; but the chief causes of the early maturity of the 

 fruit in both the preceding cases were, I am confident, the per- 

 fect maturity of the wood, and the high state of excitability, 

 which had been acquired, by a preternaturally long period 

 of rest. 



It is not, I believe, at all necessary that I should offer 

 arguments to prove, that a Vine, which cannot be made to
