I TNDER the editorship of Professor L. H. BAILEY of Cornell University, 

 ** MACMILLAN & Co. purpose issuing a series of books upon agricultu- 

 ral subjects to be known as the Rural Science Series. These volumes 

 are designed to treat rural subjects fundamentally, setting forth in readable 

 form the latest and best science and opinion as applied to agriculture in 

 its broadest sense. Whilst it is expected that the books shall describe the 

 current practices of rural occupations, it is nevertheless their chief mission 

 to expound the principles which underlie these practices, and thereby to 

 lead, by true educational methods, to the betterment of every rural pur- 

 suit. These monographs are to be written by men of recognized attain- 

 ments, in various parts of the country; and it is expected that the series 

 will be continued from year to year until it eventually covers the whole 

 field of agriculture.
