* (According to Dr. Walker this plant flourishes to the height of two or three, thou¬ 
sand feet among its native mountains, and in such situations it is particularly acceptable to 
cattle. The Doctor must here allude to sheep, who are known to be fond of it. Mr. 
Sinclair admits, that what foliage it affords is more nutritive than that of most other 
alpine grasses ; yet he considers it unworthy of cultivation. E.)

t An extremely useful grass to sow upon the banks of rivers or brooks. Horses 
cows, and sheep are fond of it when young. (On the banks and islands of the Thames 
it is generally mown twice in the year for hay. In the fens of Cambridgeshire and Lin¬ 
colnshire, immense tracts that used to be overflowed, and still retain much moisture 
though drained by mills, are covered with this grass, which affords rich pasturage and 
excellent winter fodder. In the fens of Ely, according to the reports of the West of 
England Agricultural Society, it attains the height of six feet, and is usually cut when 
about four feet high, and bound in sheaves. It is more acceptable as fodder for milch 
cows than for horses. In drains and ditches it proves a troublesome incumbrance, 
removed by an instrument called a bea,r, resembling an iron roller with revolving blades, 
and worked by horses. Mr, Sinclair states, that the nutritive matter of this grass con-
