are used, Is to set a tree In the center of the 

 square. The trees then stand like the five spots 

 of a domino, and the shortest distance between 

 trees will be about twenty-seven feet when the 

 trees In the regular rows are forty by forty 

 feet apart. This plan practically doubles the 

 number of trees which can be set on an 

 acre. 



Hexagonal or Triangular. — Another 

 method of arrangement of the trees which Is 

 becoming more and more popular Is the hexa- 

 gonal or triangular system. More trees can 

 be planted on an acre by this plan than by any 

 other, It being very economical of space. It 

 makes all adjacent trees equally distant from 

 each other and Is really a system of equilateral 

 triangles. This plan Is better adapted to small 

 areas and especially to Irregular ones, and 

 should be employed where land Is expensive and 

 culture very Intensive. It Is more difficult to 

 set an orchard after this method without error, 

 and It Is open to the objection of Inconvenience 

 in cultural operations. Most people forget that 

 while the rows running cornerwise In a rect- 

 angular or square field set after this plan may 

 be a standard distance apart, yet the right angle 

 rows (not trees) In which it may be more con-
