The above details will assist the farmer in deci- 

 ding on the comparative value of this grass From a 

 careful examination it will doubtkss appear to possess 

 merits well worthy of attention, though perhaps not 

 so great as has been supposed, if the natural place of 

 its growth and habits be impartially taken into the ac- 

 count. From the couchant nature of this grass, it is 

 denominated couch-grass, by practical men, and from 

 the length of time that it retains the vital power, after 

 being taken out of the soil, is called squitch, quick, full 

 of life, &c.
