94 PROPAGATION BY DIVISION. [CHAP. IV. 



remedy this inconvenience, a method has been 

 devised of cutting off the tips of the shoots of 

 old plants and grafting them on young plants 

 of small size; and then, after they have grown 

 for some time, cutting off the tips again and 

 regrafting them in a similar manner, by means 

 of which flowers are at length produced on 

 plants of quite a small size. The same method 

 is applied in Paris to exotic fruit-trees, to throw 

 them into fruit ; and it has been tried with suc- 

 cess with the rose apple (Eugenia Jambos), the 

 mango, &c. In common nurseries, the fruit of 

 new seedling apples is obtained much sooner 

 by grafting their shoots on common apple 

 stocks, than by leaving the young plants to 

 nature; and this plan was also practised at 

 Brussels by the late Professor Van Mons, to 

 test his seedling pears. Tender plants may 

 also be made to flower in the open air by 

 grafting them on hardy species of the same 

 genus; and thus many kinds of half-hardy 

 flowering shrubs are now grown in the open 

 ground, that were formerly kept in green- 

 houses.
