LETTER OF TRANSMITTAL. 



U. S. Department of Agriculture, 

 Division of Agrostology, 

 Washhu/ton, D. C, April 22, 1898. 



Sir : I submit herewith copy for a new and revised 

 edition of Bulletin No. 7 of this division and recommend 

 its publication. This bulletin contains 302 illustrations 

 of native and introduced grasses, accompanied by brief 

 descriptions and notes upon the distribution of each. 

 The law governing the publications of this Department 

 limited the first edition of Bulletin No. 7 to 1,000 copies, 

 which was quickly exhausted; and as applications for 

 it are continually being received, a new edition is neces- 

 sary to meet this demand. There are also some slight 

 revisions and corrections necessary to bring the work up 

 to date. Manuscript for a similar bulletin illustrating 

 over 300 additional species is now ready for the press, 

 and when published can be bound with No. 7, which 

 may be treated as Part I of "American Grasses Illus- 

 trated." Notes upon the use and value of the species 

 of economic interest M^ere published in Bulletin No. 3 

 of this division, "Useful and Ornamental Grasses." 



The drawings are all from carefully selected specimens, 



the habit sketches being made by Mr. A. H. Baldwin. 



The enlarged details were drawn by myself, with the 



exception of a few which were made by Miss M. D. 



Baker. The engraving is the work of Mr. L. S. Williams 



and Mr. George P. Bartle. The work has all been done 



in the office of the division, with the exception of that 



performed by Mr. Bartle. 



Respectfully, F. Lamson-Scribner, 



Agrostologist. 

 Hon. James Wilson, 



Secretary of Agriculture.
