Short Awned Brome Grass {Bromus marginatus, Nees). — 

 The c jlture of the short awned brome grass was introduced in 

 Iowa by R. P. Speer* in 1889, who obtained the seed from 

 Montana, collected by Prof. J. Craig, who was sent there to 

 make a collection of the most worthy and valuable grasses 

 growing in the west. It was cultivated on the college grounds 

 for a few years and merits more extensive cultivation. It was 

 distributed to a limited extent to Iowa farmers, but it has not 

 been cultivated extensively in any part of the country. It 

 gives promise of being as valuable as the Hungarian brome. 

 It is perfectly hardy, resists drouth well and is capable of pro- 

 ducing from two to three tons of hay to the acre in ordinary 

 seasons. The aftermath is also excellent. The grass has 

 become partially established in this state, both at Dysart and 

 the Iowa Agricultural College, and we commend it for trial in 

 this state. It is equal to the Hungarian brome grass on the 

 college grounds. In the season of 1900 it measured from three 

 to four feet This is what Dr. Kennedy f says in regard to it:
