183. Number of Trees that may be set upon a Piece of Land 100 

 Yards Square on a side, in Right-angled Rows of equal and un- 

 equal Distances apart. 



In this table we may substitute any other denomination of linear 

 measure in place of yards. 



184. Comparison between the Numbers set in Squares and in Quincunx 



Order. 



*We may substitute any other unit of linear measure, as in preceding table. Jt 

 will be seen that a little over 15 per cent is gained in number by the quincunx ar- 

 rangement.
