 York, D. Appleton, & Co. Philadelphia, George S. Appleton, 1845. 



This work needs no commendation from us. The author's name 

 is enough to insure it a careful perusal by all who look to science 

 as the handmaid of agriculture. It contains a full system of farming 

 in a summary way, the first part treating, in the words of the au- 

 thor's preface, " of the physical and chemical phenomena of ve- 

 getation — of the composition of vegetables and their immediate 

 principles — of fermentation — and of soils. The second comprises 

 1 summary of all that has yet been done on the subject of ma- 

 lures, organic and mineral — -a discussion of the subject of rota- 

 .ions — general views of the maintenance and economy of live 

 jjtock — finally, some considerations on meteorology and climatej 

 imd on the relations between organized beings and the atmosphere." 

 ' We hesitate not to commend this work to all who seek the aid 

 )f science in the noblest and best of all pursuits, and we do it the 

 Qore cheerfully, because we are heartily rejoiced whenever we see 

 I work for the farmer, from a man who has devoted himself as 

 las M. Boussaingault to their interests. He is a practical farmer, 

 s well as an experienced and careful chemist, and it is not by fol- 

 owing the opinions of any one man that the farmers are to suc- 

 eed- They might read and think, and compare and reason in 

 latters relating to their business, and in this way only can they 

 ,ecome the class of men they ought to be in this country, and 

 Vhich we believe they are ere long destined to be. 

 The gentlemen Appletons have got this work up in excellent 

 yle.
