 a piece of wood, it disappears, but has merely been 

 converted into carlxjnic acid and water, botli ' h

The animal or the p! time 



disappears; but in i _ nishes 



food for a new series ol iivin(^ thineps. The farmer 

 can annihilate nothing, he can only change the form 

 of his materials: every study which will enable him 

 to do this according to his wish, should be pursued 

 eagerly and perseveringly. 



The farmer must renumber that all of the - s 



with which he has to do, all of the agents t it 



his command, are connected in their composiiiuu and 

 action with the fourteen elementar)' bo<lies, organic 

 and inorganic, that have been described in this little 

 work, li' he presi>r>'cs them, or if he adds them as 

 manures in an improper form, his utmost exertions 

 are of little avail; if in a proper form, his land 

 becomes fertile, and his returns all that heart 

 could wish. If one is absent, the others may all 

 be useless; if one is present too largely, the same 

 ^ect upon the action of the others may ensue. How 

 immensely important then, and how directly practical 

 is the knowledge of these elements, and of the im- 

 mense variety of combinations in which they present 

 themselves!
