valuable fertilizer, the phosphate of lime liming was 

 prescribed, and ihe cure was perfect. 



To decry such investigations by skillful chemists, i 

 to defy the laws of nature, an occupation which finds 

 too much favor with farmers, who do not make use 

 of the brains God has given them, 



As discoveries multiply, and information becomes* 

 diffused, those farmers who decline to inquire into 

 the principles which govern their vocation, will have 

 occasion to groan more deeply than ever over the 

 unprofitableness of agriculture. 



In all parts of the brief outline here given, the 

 author will aim to be as concise as is consistent with 

 clearness. Much that w r ill be written is intended as 

 merely suggestive. The leading design is to present 

 the great principles of science which are clearly 

 connected with agriculture - T and to show how these 

 principles are involved in the daily operations of 

 the farm. 



It is hoped that the farmer will find many things 

 so presented to his mind as to inspire him with 

 renewed ardor in his honorable profession, and at the 

 same time enable him to pursue it with increased 

 pleasure. No profession or business can ever give 

 much mental satisfaction to the man engaged in it r 

 unless he has, first, a clear view of the principles 

 w T hich form the basis of his operations ; and secondly, 

 a distinct understanding of the relation between these 

 principles and his own practice. 



The author, in writing and compiling this work, is
