Other Brome Grasses. — Soft chess {Bromus hordeaceus, L.) 

 has been introduced at various points in the state for forage pur- 

 poses. Some years ago R. P. Speer introduced it on the col- 

 lege farm, but soon found] that it was an entirely worthless 

 grass. Since then it has been common on the college farm. It 

 comes- on early and makes a good growth. Its weedy character 

 should prevent farmers from sowing any more of it. 



In regard to Bromus liordeaceus Prof. F. Lamson-Scribnerf 

 says: 



"An erect annual, one to three feet high, having the sheaths, 

 leaves and spikelets of the erect panicle softly pubescent. It has 

 a marked resemblance to cheat, from which it differs in its more 

 erect panicle and hairiness. It is a native of Europe, but has 

 become widely disseminated in this country, although less com- 

 mon than cheat and smooth brome grass, but like these can 

 only be regarded as a weed. It has, however, been recom- 

 mended for cultivation on thin, sandy land where better grasses 

 will not succeed. "
