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. Svo. $5.00. 



No Americin can speak from fuller knowledge or a mire influential position than Professor Storer, and his book is the final form in which 

 have been cast the results of long study, observation, and experience, both practical an i in the class-room. 



The work is comprehensive in scope and e.xhaustive in its treatment of a great variety of subjects. Professor Storer discusses agriculture 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 lo 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. Attention is called to the merit of this work as a tex" book for class use. It has already been adopted for this purpose by the 

 State .\gricultural Colleges of Louisiana, South Carolina, Mississippi, Iowa, West Virginia. Texas, Ontario and a number of other institutions, and 

 in every case has given the utmost satisfaction. 



to agricultural literature of recent years."- 



" The work is so admirably full of experiment and sugzestion. yet so simple, that 

 we cannot but feel that its contents have been too long kept from the pubhc. It is 

 just such a book as the student of practical apiculture, the amateur, or the farmer 



; have been thoroughly learned," — TAg NiW York Com- 



" 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 eap 

 which has been open a long time." — Tht AVw York Xation. 



'' The people who buy these v-ilumes and carefully study them will enjoy all the 

 theoretical advantages of attendance at an agricultural college.^ . . . Professor 

 Storer deserves the thanks oi all the progressive farmers of America for placing his 

 knowled^ at their disposal in these volumes."— Tht iVew York Journal o/ Com'
