PREFACE TO THE FIRST EDITION. 



IN the preparation of this elementary work upon 

 the Principles of Agriculture, the author has been 

 desirous of avoiding, as far as possible, the use of 

 technical terms, in cases where other terms in general 

 use would convey the same idea. When it has been 

 necessary to employ such terms, they have been 

 explained in the simplest possible manner, so as to 

 render the book intelligible to all classes of readers. 

 Although the work is strictly elementary, the author 

 has considered it desirable to draw attention to certain 

 points in practice and in theory, which seem to be 

 insufficiently recognized by many of our practical and 

 scientific agriculturists.

PREFAO' r TO THE SECOND EDITION. 



THE r^ 5 .a sale of a large edition, and the favour- 

 able opinions which have been expressed of its utility, 

 encourage the hope that the " First Principles of 

 Agriculture" has not only been found useful for pupils 

 under instruction in the elementary stage of Agricul- 

 tural Science, but of value to those who desire to 

 inform themselves on the subject. The alterations 

 which have been made in the Second Edition will 

 probably increase its utility.
