18 DWARF FRUIT TREES 



able novelty. An example of this kind of training is 

 shown in the illustration, page 5. For this purpose 

 cordon trees are usually best ; though peach or apri- 

 cot trees in U-form or double U-form will answer 

 very well. Even apple trees or pears formed as pal- 

 mettes-Verrier can be carried up over an arched trellis. 

 Mr. Geo. Bunyard in 'The Fruit Garden" tells of 

 carrying apple trees up over the slate roof of an out- 

 building, with marked success. The fruit-bearing 

 portion of the trees, lying there on the slate roof 

 beautifully exposed to the sun above, and assisted 

 by the heat absorbed and radiated by the slate, yielded 

 large crops of apples of very superior quality. 



SOME DISADVANTAGES 



There are, of course, some disadvantages in growing 

 dwarf fruit trees, and these should be examined with 

 as much care as the advantages. The more important 

 ones are as follows: 



i. Greater expense. The trees are somewhat harder 

 to propagate, and therefore cost more. There is no 

 general demand for them in America, so that they 

 are carried by only a few nurseries and are not looked 

 upon as staple goods even with those dealers; and 

 on this account the price is necessarily increased. Thus 

 each tree costs more than a similar tree of the same 

 age and variety propagated in the usual way. But the 

 greatest increase of expense comes from the fact that 

 many more trees are required to plant the same area. 

 There is often an advantage, as already argued, in 

 planting more trees to the acre, but it costs something 

 to gain this advantage. An acre of ground can be
