This grass varies considerably in size, owing to the variety of situa- 

 tion in which it may have grown ; the same circumstance is also the 

 cause of the various appearances which are observed to take place in 

 the roots. The utility of this grass for agricultural purposes varies 

 considerably, according to the treatment. It contains, from the ac- 

 counts of Sinclair, a greater proportion of nutritive matter than any 

 other grass he submitted to experiment. Its herbage is early produced 

 in the spring, but unless grazed while young, it becomes so gross as to 

 be avoided by cattle; aud its being grazed at this period does not de- 

 crease the value or quamity of hay which it aftersvards produces ; it is 

 for the latter purpose that this grass is principally esteemed, but it is 

 also of great value amongst other grasses, both for permanent pastures 

 and the alternate husbandry. " This grass is the Highland badge of 

 the clan Sutherland, whose crest is a cat."
