IV PREFACE. 



greatly increased.. The agriculturists of this country in the 

 future will work at a serious disadvantage if they do not have 

 some knowledge of the very interesting science that underlies 

 their work. The residents of our towns and cities also will 

 find that some knowledge of the science of agriculture may be 

 of use to them, and may increase the respect and consideration 

 for the calling that contributes so largely to the general wealth 

 and welfare of this country. 



To the many who have offered help and advice and to all 

 who have in any way contributed to this work, sincere thanks 

 are offered. 



The First Principles of Agriculture, by Dr. James Mills and 

 Prof. Shaw will be found useful for reference, as some of the 

 subjects herein dealt with are enlarged upon in that work.
