82 GENERAL PRINCIPLES. 



Many varieties of the pear do not unite well with the 

 quince stock ; we therefore bud other varieties of strong 

 growth that do succeed, and use them for stocks to work 

 the others on. By this means we are enabled to possess 

 dwarf trees of many varieties, that we could not otherwise 

 have in that form. We have fruited the Dix in two years 

 by double working on the quince, when otherwise it would 

 have taken not less than seven. A great many improve- 

 ments may be effected, not only in the form and growth 

 of trees, but in the quality of the fruit, by double working. 

 Very few experiments have yet been made on the subject 

 in this country, except from necessity ; but the general in- 

 terest now felt on all matters ^pertaining to fruit tree cul- 

 ture, cannot fail to direct attention to this and similar 

 matters that have heretofore, in a great measure, been 

 overlooked.
