10S TREFOIL—RAY GRASS, &C. 
of red clover, is caused by repeatedly sowing this seed 
in the same field, without any improved culture; if 
land were laid down with the first crop after a turf 
fallow, and plenty of lime used, which proves so salu¬ 
tary in promoting the growth of seeds, no such com¬ 
plaint would exist.—See Seed Clover, and Chap. 
'VIII.-—Laying Land to Grass. 
Trefoil is in less repute than the clovers, though it 
is sometimes mixed with other seeds (being generally 
cheaper) and sown about four pounds per acre, to fill 
up vacancies, where it makes a good and sweet pas¬ 
ture ; after mowing, it cuts no figure in the aftermath, 
and the sort generally sown (medicago lupulina) is 
an annual plant, and if it continues in the ground must 
be reproduced from shedding its own seeds. 
Hay Grass is sown with the other seeds at laying land 
to grass with barley, from a peck to a bushel per acre; 
its great use is for early spring pasture, being generally 
a fortnight before any other grass; many farmers, 
upon good loams, have rejected it at times, till, finding 
their error by the lateness of their spring pastures, 
they have been glad to take it in again ; and it is now 
in general good repute ; on good rich loams a peck an 
acre is thought enough; Mr. Knight, on bis deep 
sandy loam, sows two pecks; and Mr. Richard Miller, 
on cold high loam, sows one bushel per acre; it is 
supposed to last as long as the land lays at grass, and 
when ploughed up, is succeeded by such crops as 
follow in the usual course of tillage. 
Sainfoin and Lucern are not at all, I believe, grown 
jn this county, at least I met with no instances, nor 
heard of any. Mr. C. has strongly recommended the 
growth of sainfoin, but clearly not experimentally, 
as he has not pointed out the proper soil, which should 
be
