the quihcunx system contains 113 trees. Here, as in the square 

 system, a 16M foot margin is left instead of the intended 12H feet.

"Approaching the subject from another standpoint, jve find that 

 if we desire to plant twenty-five trees 25 feet apart, we have the fol- 

 lowing space required for the different methods of arranging: By 

 the square system it will require a plat of land 125 feet square, with 

 an area of 15,625 square feet. By the triangular system it will require 

 a plat of land 137 J^ feet one way, by 111.62 the other, with an 

 area of 15,345 square feet. By the quincunx system, as the meaning 

 is usually accepted, that is with the trees 26 feet apart in the rows, 

 the twenty-five trees occupy a tract of land 100 feet square, with an 

 area of 10,000 square feet. By the quincunx system in the more 

 correct sense of having the trees with 25 feet from any tree to its 

 nearest neighbor, twenty-five trees require a tract 131 feet each way 

 with a total area of 17,161 square feet.
