ADDITIONAL REMARKS ON DRAINING. 



Since the observations at page 123, &c. on the drain- 

 ing of land, or what is commonly called water-tabling, 

 preparatory to planting, were written, it has been thought 

 necessary to add something farther on that subject, as it 

 is of very great importance that the ground on which 

 trees are planted be properly dried, and kept free of sur- 

 face-water. The following diagrams have been prepared 

 to shew the method of performing the operation to the 

 best advantage, and at the least expense. 



When waste ground is to be planted up, it ought to 

 be ascertained whether the wetness of the lands arise 

 from a want of declivity, and a retentive subsoil, causing 

 it to stagnate on the surface, or from springs in the lands, 

 as different modes of draining must be adopted in each of 

 these cases.
