42.4 X 42.4 feet. So by removing one- half of the trees, 

 it does not follow, ae is commonly supposed, that the 

 trees will be twice as fsr apart. 



Before removing any trees, it is desirable to make 

 a mep of the orchard and locate upon it by a particular 

 sign all inferior, weak trees, all vacant spaces by an- 

 other sign, ajid all desirable trees by another. If thie 

 is done, one can determine at a glance whether to re- 

 move the first diagonal rov; or the second, starting with 

 the diagonal row containing the greater number of vacan- 

 cies and undesirable trees . 



In the following diagram, the even rows show 20 poor 

 trees and I vacant epacee^ while the odd rows show 12 poor 

 trees and 3 vacant spaces. In this case, it is advisable 

 to remove the even diagonal rows, since they include 27 

 poor trees and vacant spaces out of a total of 42, The 

 question often arises as to v/hether the trees adjacent to 

 the vacancies should be removed. It is generally ad- 

 visable to remove such trees, since each one so situated 

 is likely to crowd one side of three other trees.
