230 PROPAGATION OF PLANTS. 



grow thriftily upon the Quince, and buds of these are 

 inserted in the usual way, and near the ground. The 

 next season, after the shoots from the buds have nearly 

 completed their growth of the season, buds of the feeble- 

 growing varieties, or those which appear to have very 

 little affinity for the Quince stock, are inserted in the 

 young growth of the Pear wood six to twelve inches above 

 its junction with the Quince. The stock is then treated 

 as it was the year previous, and the following spring the 

 stock cut back to within four to six inches of the bud in- 

 serted in the Pear wood. This small section or piece of 

 wood of a vigorous-growing variety, uniting with the 

 Quince stock below, and supporting another abo^e, will 

 have a very great irriluence in the future growth of the 

 tree. Doubled worked trees cost twice as much to raise 

 as single worked, but they are worth the difference to 

 any one who desires dwarf Bartlett, Seckle, and similar 

 varieties, which do not usually succeed when grown 

 directly on Quince stocks. Doubled worked trees, how- 

 ever, should never be trained as standards, as the Quince 

 has a rather feeble root system, producing few large 

 lateral roots ; consequently, if the top is trained high the 

 tree is likely to be blown over, ani all of the roots thrown 

 out. 



The White Thorn (Cratcegus coccinea), may also be 

 employed as a stock for the Pear, and in moist, heavy 

 soils it is fully equal, it not superior, to the Quince. There 

 are several native species of the Thorn, some much 

 stronger growers than others; the largest and most vigor- 

 ous species should be selected, if to be employed as stocks 

 for the Pear, or even for propagating the ornamental 

 varieties of the European Hawthorn. 



The common Juneberry or Shadbush (Amelancliier), 

 and the Mountain Ash (Pirus Americana and P. Aucu- 

 parid), may be employed as stocks for the Pear, but are 

 usually considered inferior to the Pear and Quince. The
