THE Iowa Geological Survey takes pleasure in presenting 

 to the state as a Supplementary Report, Part II of The 

 Grasses of Iowa. The hearty reception given the volume 

 already in the hands of the public has fully borne out the 

 prophecy that its subject-matter would appeal to all who are 

 interested in developing the agricultural interests of the state. 

 The vast amount of work represented by this volume, as well as 

 by volume 1, was done absolutely without cost to the state. 

 Many of the plates used in illustrating the species of grasses 

 were also generously furnished by the writer of this report with- 

 out expense to the state.
