DOUBLE SQUARE SYSTEM. 

 (Figure No. 1 1.) 



Standard and Dwarf Trees. 

 Standard trees 34 feet apart each way; Dwarf 

 trees loft, and 12 ft. from the Standard trees. 



This system is somewhat new in 

 this State, but is coming into favor, 

 especially by those setting out seed- 

 lings and varieties of home origin 

 for Standard purposes. As the 

 Standard trees do not come into 

 bearing for several years, Dwarf 

 trees are planted between, as they 

 bear several crops before the others 

 begin fruiting. They will also re- 

 main small, and will not interfere 

 with the Standard orchard trees. 



ANOTHER SQUARE SYSTEM. 

 (Figure No. 12.) 



For Standard and Dwarf Trees. 



This is exactly the same as the 

 square system, only that the rows are & \_ 

 doubled, Dwarf trees being planted in j i 

 between the Standards.

EXTENDING THE ROOTS. 



/ 



It is a common practice among 

 growers to place the tree in the hole, 

 fill it up with soil, and then tramp it. 

 As the roots are covered with thick 

 mud they will stick together, and if 

 the tree grows it will not do as well 



as when the roots are extended with care. This is very sim- 

 ple. The hole is half filled with earth, so as to form a mound 

 in the hole, the shovel handle is driven down in the center of 

 the mound, and on being withdrawn a deep hole is left, suffi- 

 ciently large and deep enough to admit the taproot of the tree, 

 then the roots are spread over the mound (Figure No. 13), the 

 soil is lightly pressed ; heavy tramping is not necessary, as the
