pounds sown with other seeds for pasture, will render a benefit in anysituation that wants it. Twenty-four pounds is usually sown on an acre«"hen intended for the sole crop, and sown under corn.

51. POTERIUM Stmguismta. Burnet. —This plant grows in cal-careous soils, and is in some places much esteemed. On the thinchalky soils near Airesford in Hampshire, I Iwe observed it to thrivebetter than almost any other plant that is cultivated. Sheep are par-ticularly fond of it; and 1 have heard it said that the flavour of thecelebrated Lansdown mutton arises from the quantity of Burnet grow-ing there. It is also the favourite fond of deer. This will grow wellin any soil, and there are few pastures without it hut would be bene-fited by its introduction. Twenty-five pounds per acre are sown alone :eight pounds mixed with other seeds would be sufficient to give a goodplant on the ground.

52. SANGUISORCA officinalis. Great Canada Burnet.— Cattlewill eat this when young; and it has been supposed to be a useful plant,but 1 do not think it equal to Burnet.

It is perennial, and is often found wild, but has not yet been culti-vated.

53. TRIFOLIUM pratense. Red Ciovee. —This is a very old plantin cultivation, and perhaps, with little exception, one of the most use-ful. It is very productive and nutritive, but soon exhausts the soil;and unless it i-> in particular places it presently is found to go oil', whichwith the grazier is become a general complaint of all our cultivatedClovers. It is also well known, that if the crop is mown the plant isthe sooner exhausted.

Seeds of Clover have the property of remaining long in the groundafter it has become thus in a manner exhausted; and it frequently oc-curs that ashes being la'd on will stimulate the land afresh, and causethe seeds to vegetate; which has given rise to the erroneous opini n withmany persons, that ashes, and particularly soap ashes, will, when sownon land, produce Clover.

Red Clover is usually cultivated in stiff clays or loamy soils; andwhen sown alone, about sixteen or eighteen pounds of seed are used forthe acre.

54. TRIFOLIUM medium. Zigzag, or Mountain-Clover. —Is insome degree like the preceding ; it produces a purple flower, and thefoliage is much the same in appearance: but this is a much strongerperennial, and calculated from its creeping roots to last much longerin the land. It is equally useful as a food for cattle, and does not pos-sess that dangerous quality of causing cattle, to be hove, or Mourn, byeating it when fresh and green. This plant is, however, only to bemet with in upland pastures, and there in its wild state; for it does notseed verv abundantly, and is not in cultivation.
