ENGLISH FARMING PAST AND PRESENT 



By the Right Hon. LORD ERNLE (Rowland E. Prothero), 

 President of the Board of Agriculture and Fisheries, 1916-1919. 

 Third Edition. 8vo. 12s; 6d. net. 



A chapter has been added to the third edition of this book on agriculture during the years 

 igi4-i8. Historically, the interest of the period lies in the experiment of Slate Control, the form 

 which it assumed, the results that it attained. Practically, the exceptional conditions which 

 necessitated the adoption of the experiment must to a great extent neutralise its utility as a guide to 

 action in times of peace. 



The appendices on.Corn Prices and Agricultural Wages havj aUo been brought up to 19JO.

The features of the book are the particularly clear arrangement of the text, with the 

 right-hand pages left blank to enable the student to draw up his own diagrams, and 

 the remarkably fine execution of the 105 illustrations, most of which are entirely 

 original, and have been drawn from actual dissections.
