2 Introduction. 



designed not only for farmers but also for agricultural students 

 and botanists. The former, who have little time for reading 

 or study, will learn to know from the illustrations many grasses 

 now unfamiliar to them, and gather from the briefly stated facts 

 relative to the economic values of the several species a great deal 

 that may be of direct use to them. The agricultural students and 

 botanists of the State have here a means for identifying and class- 

 ifying any grass now known to occur within the limits of Tennes- 

 see, and to acquire a fair idea of their external characters and 

 habits. While this Bulletin is only designed for the use of Ten- 

 nesseeans, those living in other States may tind it helpful at times 

 in determining grasses. None of the species described are limited 

 to the State, and of course the descriptions and illustrations are 

 as applicable in one place as in another. The specific descriptions 

 are for the most part drawn from specimens in hand, and they are 

 usually more complete than those given in our general manuals. 

 The illustrations, which were drawn by Mr. Theo. Holm, of Wash- 

 ington, D. C, were all prepared especially for this Bulletin, and 

 quite a number of the species figured are here illustrated for the 

 first time.
