 a point of writing for the layman as well as for the expert merits the 

 serious consideration of the farmer no less than that of the student, the

"No one is more competent than Mr. Hall to turn the riches of 

 Rothamsted to account for the benefit of practical farmers, and his latest 

 volume constitutes a fit companion to 'The Soil,' and that in itself is a 

 high compliment. The present volume is a natural and valuable 

 supplementary treatise to the large and complex subject dealt with in 

 the initial volume of the series. . . . The subject is an old one, and 

 farmers may plead that they have been inundated with literature bearing 

 upon it. In regard to a question of this son, however, Rothvimsted 

 stands upon a level by itself. It is the centre of scientific investigation 

 of matters pertaining to the land, and Mr. Hall has in the pages of his 

 handsome volume shed the radiating light of the world-renowned station 

 upon the intricacies of soil management with telling effect." Field.

 alike by farmers and students." Field.
