LETTER OE TRAXSMEFrAL. 



U. S. Department of Agriculture, 



Division of Agrostology, 

 Washington, D. C, August 10, 1897. 

 Sir: I have the honor to transmit herewith and recommend for 

 publication as Bulletin No. 9 of this Division, a report by L. H. Pam- 

 mel, professor of botany in the Iowa Agricultural College, on the 

 grasses and forage plants of Iowa, Nebraska, and Colorado. The three 

 States included in this report, especially the first named, are great 

 stock-raising States, and all information pertaining to the food sup- 

 ply — the grasses and forage plants — for the cattle, horses, and sheep 

 can not fail to be of interest. This report is in line with the investi- 

 gations of the grasses and forage plants of the Northwest now being 

 carried on by the Division. 



The report here presented is divided into three parts, the first includ- 

 ing general observations upon the physical conditions and important 

 questions relative to forage production in the States named; the second 

 is devoted to an enumeration of the more important grasses and forage 

 plants of these States, alphabetically arranged, with economic notes; 

 in the third part the author presents a classified list of the grasses of 

 Iowa, Nebraska, and Colorado collected by him during the seasons of 

 1895 and 189G. 



Respectfully, F. Lamson-Scribner, 



Agrostologist. 

 Hon. James Wilson, 



Secretary of Agriculture.
