The above details will assist the farmer in deciding on 
the comparative value of this grass. From a careful ex- 
amination it will doubtless 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 account. 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.
