PREFACE 



TO 



THE FOUETH EDITION. 



oXKo 



Although the third, or popular, edition of this work met an 

 acknowledged want, there is a continued demand for the book 

 in its original form, including the coloured plates. As the 

 publishers do not possess a single copy of either the first or 

 second edition, I have again revised the text, especially the 

 first chapter in view of the increasing importance of dairy 

 management. 



Hints are added on the means of identifying various 

 grasses when not in flower ; and on page 102 will be 

 found a tabular statement of results obtained from manuring 

 experiments on a young pasture during five successive years. 



Drawings on an enlarged scale of seeds of the grasses 

 illustrated are, for the first time, included on pages 140 to 172. 



I gladly embrace this opportunity of rendering sincere 

 thanks for numerous friendly reviews of former editions, and 

 also for kind suggestions which have been communicated to 

 me by letter.
