WORKS BY A. D. HALL, F.R.S. 



Formerly Director of the Rothamsted Experimental 

 Station 



" In these three volumes students and practical men have 

 a compendium of information dealing with all that the most 

 recent scientific investigations can teach with regard to 

 agriculture, primarily, but partly also as regards horticulture." 

 — Agricultural Economist. 



The Soil 



An Introduction to the Scientific Study of the Growth of 



Crops. With Diagrams, etc. Second Edition, revised 



and enlarged. 5 s. net. 



" This is a remarkably well-arranged and well-written volume. In its 

 way it is a masterpiece, and it leaves on the mind an impression of great 

 and reasonable hope." — The Times. 



Fertilisers and Manures 



With Illustrations. 5s. net. 



"The teaching in this book is very clear, the amount of information 

 contained in it is very great, and the arrangement into chapters, together 

 with a good index, makes reference easy. It is a work that should appeal 

 both to the farmer in search of information on some particular point of 

 practice, and to the student who is making a serious detailed study of the 

 question of the effect of manures on plant development." — farm and Home. 



The Feeding of Crops and Stock

 Illustrations. 5s. net. 



*' The products of Mr Hall's knowledge and experience are always 

 welcome in the manuals which come from his facile pen, but that now 

 under notice is especially so, as it is complementary to his works on soils 

 and manures which have previously appeared." — A griadtnral Economist,
