DOUBLE WOEKING. 145 



that govern to a great extent these characteristics in the 

 fruit. Any free-growing varieties may be budded on 

 the Quince, for the purpose of double working, although 

 some care should be taken to obtain such as liarmon- 

 ize with the Quince. The Virgalieu and the Buffam 

 are the best, although not the most vigorous growers ; 

 yet most pears grow well, when propagated upon 

 them. 



The Beurre d'Amalis and Soldat Laboureur, are 

 very vigorous growers, and make good stocks for 

 double working. There are such obvious advantages 

 in double working, that it seems almost superfluous 

 to mention them, yet that nothing may be omitted to 

 secure success, we present them in a concise form : 



1. Pears that refuse to grow, or grow but feebly, 

 or are short-lived upon the Quince, but are coarse, 

 gritty, or small sized, when grown upon the pear 

 stock, like the Beurre d'Aremberg, often become first- 

 rate by double working. 



2. Yarieties that are so tardy in bearing upon the 

 pear stock as to exhaust the patience and faith of the 

 grower, yet will not harmonize directly with the 

 Quince, will, by double working, come early into bear- 

 ing. The Dix and Seckel are examples of this. 



3. Grafting, which cannot be practiced with suc- 

 cess directly on the Quince, may be performed on the 

 Pear portion of the stock. 



4. Some varieties that bear quite early on the pear 

 stock, but are of comparatively slow growtli, are pro- 

 duced in greater vigor ujDon the double stock, in con- 

 sequence of the increased vigor acquired from the 

 strong growing variety first worked upon the Quince.
