14 AMERICAN MANURES.

We do not intend any one to infer, that we 

 ignore, or attempt to bring science into discredit. 

 The farmer needs all the science he can get, and 

 he would find himself greatly benefited by a 

 general application of all its discoveries. But 

 he needs an interpreter of the truths and 

 facts that have been demonstrated by the 

 patient research of those who have been favored 

 with opportunities,, time and means to devote 

 to the subject. 



And in this book we shall endeavor to give 

 all the practical knowledge, so far developed 

 and established as truths and fixed facts (not 

 speculations), having a particular connection 

 with agriculture, and this will be rendered in 

 such plain language that a child may read and 

 understand. 



The second class of writers, whose productions 

 are commonly found in the Agricultural Journals 

 of the day, fall into the opposite extreme. 



These writers are practical farmers, and write 

 with the commendable intention of giving the 

 results of their experience to benefit their 

 brethren.
