fectually drained, and freed from stones or other obstructionsto tillage; and the soil, if possible, dressed with lime or marl.If judiciously cultivated, on the principles endeavoured to beelucidated, such improved portions will never revert to a stateof wildness; and the only extraordinary expence they willever require is, occasionally renewing surface drains and re-pairing the inclosures.

In all these elevated and moist situations, tillage can onlybe considered as advisable, in so far as it conduces to theproduction of turnips and hay, and the permanent improve-ment of the soil for pasture. The crops of grain, which ne-cessarily form parts of the rotation, can never be dependedupon for profit, any farther than as the straw is useful andnecessary as litter and fodder for the cows and horses, and asproductive of muck for the cultivation of turnips.

In all, or in most of these high situated pasture farms, thereare haughs or holms on the sides of rivulets, which are moreor less susceptible of cultivation or improvement. Thesemay either be managed in the same manner already pointedout for the cultivation of the moor-edges, which of course neednot be here repeated ; or they may be converted into haymeadows by means of irrigation. But as this latter improve-ment, as yet new in the husbandry of Scotland , is appropria-ted for discussion to a different division of this work, it canonly be mentioned incidentally in this place.
