AGRICULTURE 



In some of its relations with Chemistry, by F. H. Storer S. B., A.M., Professor of Agricultural 

 Chemistry in Harvard University. 2 volumes. 8vo. $5. Special net rates to teachers. 



No American can speak from fuller knowledge or a more influential position than Professor Storer. This work has been especially 

 prepared in the interest of students of agriculture. It is the final form in which have been cast the results of long study, observation, and 

 ■experience, both practical and in the class-room. The style is clear and straightforward, and the discussion throughout is open to the 

 comprehension of any intelligent reader. As an authoritative treatise the work cannot fail to take the highest rank, and although it is 

 intended mainly for those who are specially interested in some form of agricultural industry, the general reader will find much that is of 

 •extraordinary interest in the domain of natural science. 



The work is comprehensive in scope and exhaustive in its treatment of a great variety of subjects. Professor Storer discusses agri- 

 culture in all those important relations into which chemistry enters in any degree — the general relations of soil and air, the atmosphere 

 as a source of plant-food, the relations of water to the soil, movements of water in the soil, tillage, implements and operations of tillage ; 

 in short, Professor Storer describes the relations of soil, air, and water to the plant and to each other, tillage, manures and fertilizers, 

 rotation of crops, irrigation, the growth of crops, and staple crops. 



The N.Y. Nation. " This interesting work is a valuable addition to the literature of agriculture. . . . It is eminently practical upon 

 ■the subject of tillage and fertilization, and it fills a gap which has been open a long time." 



The N.Y. Journal of Commerce. " The people who buy these volumes and carefully study them will enjoy all the theoretical advantages 

 of attendance at an agricultural college. . . . Professor Storer deserves the thanks of all the progressive farmers of America for placing his 

 knowledge at their disposal in these volumes." 



The N.Y. Commercial ^Vdvertiser. " The work is so admirably full of experiment and suggestion, yet so simple, that we cannot but feel 

 that its contents have been too long kept from the public. It is juscsuch a book as the student of practical agriculture, the amateur, or the farmer 

 needs after the first lessons have been thoroughly learned."

OR, CHRISTIAN ETHICS. By Mark Hopkins, D.D., LL.D., 

 Late President of Williams College. i2mo, §1.75.

 to educational uses. It appears in a new edition, which has been in 

 part rewritten in order to bring it into closer relation to his '* Outline 

 Study of Man," of which work it is really a continuation.
