PREFACE. 



During the past few years a large number of tests of grasses and 

 forage plants have been made by the Nebraska Agricultural Experi- 

 ment Station in cooperation with the United States Department of 

 Agriculture. The Department has furnished a part of the seeds for 

 these tests, and has from time to time, at the request of the director 

 of the station, made suggestions regarding the nature and plans of the 

 work to be done. At the request of Prof. T. L. Lyon, Associate 

 Director of the Station, Prof. A. S. Hitchcock, of this Office, visited 

 the station during the past winter and prepared the following bulletin 

 from notes made by the officers of the station. It is a matter of 

 gratification that these notes were in such form as to render the task 

 comparatively easy. 



The present paper contains the results of the cooperative experi- 

 ments and also some general information upon the forage conditions 

 of Nebraska, in the preparation of which Professor Hitchcock has 

 been in constant consultation with Professor Lyon. 



The results of these experiments are of interest to many of the 

 surrounding States having similar climatic conditions and in which 

 many of the same forage plants are grown.
