to remain after the nurses are cut down, should be 

 placed at the intervals which may appear requisite, 

 according to this calculation. As there will he 

 others planted between them, it will be better that 

 they should be planted rather too thin than the 

 contrary,- — as this mistake may be easily corrected, 

 by allowing some of the supernumeraries planted at 

 first to remain wherever they may be required, to 

 fill up vacancies, arising from the others not reach- 

 ing the size that had been anticipated. 



If the ground, either naturally, or from being 

 made up with additional earth, be from 15 to 20 

 inches deep of vegetable mould, and of a description 

 that will answer with the oak, elm, or ash, these 

 trees may be allowed at least 30 feet from each 

 other. Between 12 and 15 inches deep of vege- 

 table mould, 24 feet may be allowed between the 

 larger species of trees ; and when the depth is be- 

 tween 8 and 12 inches, from 15 to 18 feet will be 

 sufficient. From 8 to 12 feet may be considered as 

 the requisite distance in soils of an inferior quality, 

 and where the species planted grow to a less gigan- 

 tic size. The quick growing species mentioned 

 above should be planted among the others, at such 

 intervals, that the average distances of the whole 

 from one another may, in the best land, be 6 or 7
