own. An additional reason for sparse planting has lately 

 become important, the necessity of spraying for insect 

 and fungous pests ; and for this reason, as well as to allow 

 of better tillage, the outside rows should not be set close 

 to fences. The distance at which trees may be set depends 

 much on the system of pruning. If heading-in is followed 

 vigorously and systematically, trees may be set a third 

 nearer than if allowed to take their natural form. 

 Heading-in should always be practised with dwarf trees, 

 and many of our best growers pursue it regularly with 

 peaches, plums and quinces. Wide planting is the safer rule 

 for the generality of cases. The following table may be 

 supposed to represent the outside average limit for the 

 planting of fruits in the northeastern states, when the 

 plants are allowed to take their natural form : 



Apples 35 to 45 ft. each way. 



Apples, dwarf 10 to 15 ft. 



Pears, standard 20 to 25 ft. 



Pears, dwarf 12 ft. to 1 rod. 



Quinces 1 rod. 



Peaches and nectarines 20 ft. 



Plums 20 ft. 



Apricots 20 ft. 



Cherries, sour 20 ft. 



Cherries, sweet . . * 30 ft. 



Figs 20 to 25 ft. 



Pecans 40 ft. 



Grapes 6x8 to 8x10 ft. 



Currants 4x6 to 6x8 ft. 



Blackberries 4x7 to 6x9 ft. 



Raspberries 3x6 to 5x8 ft. 



Strawberries 1 x 3 or 4 ft. [way. 



Cranberries 1 or 2 ft. apart each 



These are safe distances. In certain cases, however, 

 when the soil is strong and the grower makes thorough
