IV PREFACE. 



this science farther the above works are con- 

 fidently recommended, especially Liebig's pro- 

 found work " On Organic Chemistry, as ap- 

 plied to Agriculture," which contains all that 

 is at present known on the subject, and in which 

 the important discoveries announced are only 

 equalled by the happy manner in which they 

 are illustrated. 



It must be permitted to me again to notice 

 that my object in compiling the following 

 pages, has been a desire to convey such infor- 

 mation to the Agriculturist as may be found 

 on trial to assist him in his pursuits, and to 

 explain the rationale of some of the processes 

 nature employs in the Vegetable Kingdom — 

 with what success, it is for the reader to deter- 

 mine. With this intention, and this only, have 

 I thrown together the following matter ; and 

 the little merit, if any, to which I may be en- 

 titled, must arise from the circumstance of my 

 having in some measure simplified a subject, 

 which, in its usual form, is too abstruse for the 

 general reader.

November. 1841.
