"It will thus be seen that there is a certain gain in the amount of 

 land required to plant twenty-five trees, by using the triangular 

 rather than the square system of planting. This gain is evident for 



Fig. 57. Twenty-five trees planted according to quincunx system. 



even so small a tract of land as that required for twenty-five trees; 

 and since it is evident that there is a sUght loss by the triangular
