Oha. This plant was introduced here a few years ago, and attracted considerable notice, as a grass likely 

 to be vslusblf, in affording a .=upply of hay, in seasons of scarcity. In this point of view it is, doubt- 

 less, wo'-thv of notice, as it makes good hav, if secured in good order: but it takes damage very readily, 

 in dull we.^ther. The grain is not considered ot much importance, by our farmers; and the culture of the 

 plant is rather neglected, at present. The seed is usually sown about the middle of May. This is suppo- 

 sed, by some, to be only » variety of either S. italica, or S. tiridis.
