This is one of those grasses which neyer thrives when cultivated simply by itself; it requires

IS always present in the richest natural pastures. From the above details, its produce is 

 very great, nor its nutritive qualities considerable. The nutritive matter it affords from its leaves, 

 (the properties of which are of more importance to be known than those of the culms, for a per- 

 manent pasture grass), contains proportionally more bitter extractive, than what is contained in 

 the nutritive matters of the grasses with which it is more generally combined in natural pas- 

 tures, and which have just now been mentioned. This latter circumstance is the chief claim
