THE PEAR. 



trees, which have become enfeebled by long bearing and 

 sparse pruning, may be thus rendered thrifty and vigorous. 



With trees of large si/e, it may be safest to change the 

 upper half in one year, and the re- 

 mainder the next, for the purpose 

 of avoiding too great a check in 

 growth. 



Younger trees, or those but a few 

 years old, of undesirable sorts, but of 

 straight growth, may be used for 

 stocks on which to work new heads 

 of crooked or slow growers at stan- 

 dard height. Fig. 642 represents a 

 tree of the Virgalieu worked over to 

 the Winter Nelis, the former being 

 a straight and handsome tree, and 

 the latter the most crooked grower 

 known. A few buds of the Winter 

 Nelis are inserted into the side limbs 

 of the Virgalieu so as to form an 

 even, well-balanced head. The same 

 result may be obtained by grafting these limbs in spring.
