9outhe:rn parts of Europe^ or the adjoining parts of Asia, has 



completely natiiraliz<?d itself in Britain, and has acCjuired, in at 



great number of instances, the pxivj^er to ripen its fruit in the- 



early part even of an Unfavourable summer : the crab tree has 



in the same manner) adapted its habits to the frozen regions 



of Siberia. But when wfe import either of these fruits, in their 



cultivated state, from happier climates, they are ofteri found 



incapable of acquiring a perfect state of maturity even when 



trained to a south wall. 



Whence the As the pear and crab tree, in the preceding Cas6s^ have ac- 



vine and peach 



may probably 



flourish here than those in which they were placed by nature^ we have some'

section. 



ficial'heat!^' grounds of hope the vine and peach tree maybe made to 

 adapt their habits to oivr climate, and to ripen their fruits 

 without the aid of artificial heat^ or the reflection of a wall ; 

 and though Vvc are at present little acquainted with the mode 

 of culture best calculated to produce the necessary changes in 

 the constitution and habit of plants, attentive observation and 

 experience will soon discover it ; and experiments have 

 already been made, which prove the facility of raising as fine 

 varieties of fruit in this country, as any which have been im- 

 ported from others. 

 Propagation by Almost every plant, the existence of which is not conSned 

 seedaad by iq ^ single summer, admits of two modes of propagation :. by 

 Division of its Parts, and by Seed. By the iirsi of thest; 

 methods we are enabled to multiply an individual into many ^ 

 each of which, in its leaves, its fl-c^wers, and fruit, permanently 

 retains, in ever)- respect, the character of the parent stock., 

 No new life is here generated ; and the graft, the layer, and 

 cutting, appear to possess the youth an<.l vigour, or the age 

 and debility of the plant, of which they once formed a part*. 



* The diseased state of yonnc; grafted trees of the golden: 

 ,plppiri, and ttie debasement of the fia\'onr of that iVnir, afford one, 

 amongst a thousand instances v/hieh may be adduced, of the 

 decay of those varieties of fruit '.vhich have been long propaga>* 

 ted by grafting. iStc.
