1. — Acre, of shape 220 feet long by 198 feet wide. 

 Deducting dray road (12 feet wide), we have — 



Area to be planted = 174 feet wide by 196 feet long, 

 which will admit of 10 rows, with 11 trees in each row, 16 feet apart,

2. — Acre, of shape 264 feet long by 165 feet wide. 

 Deducting dray road (12 feet wide), we have — 



Area to be planted = 141 feet wide by 240 feet long,

 Deducting dray road (12 feet wide), we have — 



Area to be planted == 108 feet wide by 306 feet long,

We may form a second table by excluding all consideration of the frac- 

 tional spaces adjacent to the dray road, and simply calculating how many 

 times the area required for each tree is contained in the available areas of 

 acres of each of the preceding forms. A table so calculated is as follows : —
