Lucubrations on Soils No. 5. 



Continued ;rom page 359. 



"Ik is no less important to our purpose to adopt Mr. 

 Kirvvan's definition of JNlanures, which is the most ac- 

 curate I have met with, and convej's precise, distinct, 

 ai:d clear ideas, which renders it extremely valuable. — 

 I copy th.; chapter with but Httle variatioHj and nearly 

 at length, as 1 did the preceding one. 



OF MANURES. 



Manure denotes any substance or operation by whicli 

 a soil is improved. To improve a soil is to render it 

 capable of producing corn, legumens, and the most use- 

 ful grasses. 



The substances principally used as manures are chalk, 

 lime, clay, sand, marl, gypsum, ashes, stable dung: 

 mucks, farm yard dung, pounded bones, sea weeds, 

 sweepings of ditches, old ditches. Other manures or 

 top dressings, as they are employed chicHy to promote 

 the growth of vegetables, and not merely with a view 

 of improving the soil, I omit. 



The operation used to improve soils are fallows, drain- 

 ing;, paring and burning. As to paring and burning 

 jny experience in burning leads me to believe it cannot 

 be done without injury rather than benefit.
