and the next, the different quantities of 

 moisture. On thin soils, a tree will often 

 be much stinted, in that respect, in the 

 principal growing season, which can never 

 happen in deep ones ; certainly, on the 

 latter, the plants will grow largest upon 

 a given surface. — The subject is here 

 brought forwards, to furnish some hints 

 for fixing the ultimate distances of trees. 



The current opinion upon this point,
