CHEMICAL NEWS. "Viewing the book in its present form as a 

 whole, it may safely be pronounced, not merely a treasury of useful 

 information, but a medium for the inculcation of sound, and in the 

 highest sense practical, principles. It would be a happy day, not 

 merely for the agricultural interest, but for England in general, if 

 farming were generally carried on in the light of the law laid down in 

 these pages."

FARMERS' HERALD. "This catechism, which is written in simple 

 and intelligent language, is a useful and instructive handbook for 

 farmers ; it will no doubt be a favourite amongst agriculturists." 



ABERDEEN JOURNAL. "It is an admirable compendium of the 

 elements of agricultural chemistry, and forms an excellent introduc- 

 tion to a more detailed study of the subject. Its clear, concise, and 

 simple way of stating facts renders it specially serviceable for the 

 study of the young in rural districts ; and practical farmers will find 

 it very useful as a summary of chemistry and geology in their rela- 

 tion to agriculture."
