3d. He prevents the sudden fall of temperature and consequent 

 chilling of the growing plant, decreasing the effect of the sun's 

 heat not on the surface only, but at the roots. 



4th. He removes obstructions to plowing, and poaching by the 

 feet of his teams. 



5th. He prevents foot rot in his sheep, foot ail in his cows, 

 chills, colds and bad health to his stock, generally. 



And if his land is drained properly and thoroughly, every drop

 pass through both surface and subsoil, until it finds the drain j

 organic constituents of the soil. 



5th. The deleterious ingredients in the soil are rendered soluble 

 and carried off in the drain.

 the subsoil, where they rot and form food for other plants. 



7th. The subsoil changes and becomes fit to mix advanta-

 should happen to be clay, and the surface sand, or vice versa, the 

 benefit accruing would be great. 



8th. The enhanced fertility of well drained land is due to the 

 increased depth of feeding surface for the roots of plants. It will 

 endure wet and drought far better than undrained land ; during 

 long and protracted droughts my thorough drained fields call at- 

 tention by their beautiful verdure, the soil of such a field never 

 bakes. It is easily tilled, and always in condition for agricultural
