INTRODUCTION. 27 



It rniist be borne in mind that, as scieniifio investigation nad 

 advanced in modern times, it has brought its contributions to 

 Agriculture from a great variety of sources, each of which 

 brings something peculiar to itself. Chemistry has explained 

 the composition of soils and manures. Botany has solved the 

 mysteries of plant growth. Vegetable and Animal pliysiology 

 have lent invaluable aid. Geology, Mineralogy, and, indeed, all 

 the sciences, have done their share, and the farmer has only to 

 use the knowledge so lavishly thrown out before him. 



In considering the value aud uses of a high standard of Agri- 

 cultural Literature, it is not to be forgotten that it tends to 

 create enthusiasm, and must exert a powerful influence to draw 

 and to keep the young upon the farm, and to stimulate them 

 to con-itant efforts to attain greater excellence and success. 

 In this view, it is hardly possible to ovvr-estimate the value 

 and practical importance of well selected works on agricultural 

 and horticultural subjects. AVhen any one begins to read 

 what has been written by others about any pursuit, and to 

 reflect upon the facts and theories he finds stated, when he 

 learns the results of investigations and experiments, and sees 

 the labor and care bestowed upon them, he will soon become 

 interested himself. As he proceeds his interest will grow into 

 enthusiasm, and this enthusiasm will give him a love for his 

 occupation and a strong desire to elevate it and attain a high 

 position in it. Hence, he will gain vigor and energy which 

 will insure success. 



The young farmer, like other men, is subject to these influ- 

 ences. If he work in his calling with enlightened views, look- 

 ing at its scientific and theoretical side while attending to its 

 practical labors, he will acquire the strong interest in it, and 

 love for it which is so essential to success. His enthusiasm 

 will keep him upon the farm, and carry him through its
