that affect a similar soil.



39. POA pratensis. SMOOTH-STALKED MEADOW-GRASS.--This is also a grass of
considerable merit when it suits the soil; it affects a dry situation,
and in some such places it is the principal herbage; but I have
cultivated this by itself for seed in tolerably good land, and after
some time I found it matted so much by its creeping roots as to become
quite unproductive both of herbage and seed. Care should therefore be
taken that only a proper portion of this be introduced. The seeds of
this and Poa trivialis are the same in bulk, and probably the same
proportion should be adopted. The seeds of both species hang together by
a substance like to cobwebs, when thrashed, and require to be rubbed
either in ashes or dry sand to separate them before sowing.

SECT. II.--ARTIFICIAL GRASSES [Footnote: This technical term is
generally known to farmers. It is applied to Clovers, and such plants as
usually grow in pastures, and not strictly Gramina.].

Under this term are included such plants as are sown for fodder, either
with a view to form permanent pastures when mixed with the grasses, or
as intermediate crops on arable land. In those cases they are usually
sown with a spring crop of Oats or Barley, and the artificial grasses
