Tares or Turnips. The seed is about six or eight pecks per acre, and ten
pounds of Clover mixt as the land best suits. Although this is a very
advantageous culture for such purposes, and when the land is not to
remain in constant pasture; yet it is by no means a fit grass for
permanent meadow, as it exhausts the soil, and presently goes into a
state of decay for want of nourishment, when other plants natural to the
soil are apt to overpower it. There are several varieties of this
grass. Some I have seen with the flowers double, others with branched
panicles; some that grow very luxuriantly, and others that are little
better than annuals; and there is also a variety in cultivation called
PACEY's Rye-grass, much sought for. But I am of opinion that nothing but
a fine rich soil will produce a very good crop, and that the principal
difference, after all, is owing more to cultivation or change of soil,
than to any real difference in the plant itself.



29. MELICA coerulea. BLUE MELIC-GRASS.--This is common on all our heaths;
it appears coarse, and not a grass likely to be useful. Yet this kind is
spoken of by Dr. Walker under the name of Fly-bent, who says it is one
of the most productive and best grasses for sheep-feed in the Highlands
of Scotland, where it grows to the height of three feet, a size to which
it never attains in this part of the country. It is found in all soils,
both in dry and boggy places.



30. PANICUM germanicum. GERMAN PANIC, or MOHAR.--I notice this plant
here, although it is not a native of this country; neither is it in
cultivation. It was introduced some years since by Sir Thomas Tyrrwhit
