1 Implements of Lf ufoandry.—Miner-—-Paring-Ploughs.

a crop of barley or turnips, and under the following fyftem for wheat, and the labour and expencé in the latter cafe, of raking, picking, and burning weeds, that the advantages of the trench-plough mutt be greater than is, perhaps, gene.

rally fuppofed. There is alfo another confideration of fome importance in this fyf. tem of management, which is, that the ftaple of the foil is increafed in depth, and its parts fo divided and loofened, that the fibres of the roots of the crop are more at liberty to range, and of courfe to take up their proper nourifhment, which muft render it more certain and of better quality. A plough of this kind, with a double fhare, one placed directly over the other, has been much employed by fome good cultivators in the fouthern parts of the kingdom. By this means, one narrow fhallow furrow may be taken off the furface, and another beneath it any moderate depth that may be required; and it will perform its bufinefs to ten inches in depth, as well as only five or fix. It is an highly ufeful tool in putting in one crop immediately after another; a mode of cultivation which could not indeed be well prattifed without it. In this way rye, or other green crops, which have great height of ftem, may be turned down without leaving any part of them {ticking out in the feams or crevices between the furrows; whatever is turned in be- ing really covered, by which means the furface is of courfe perfectly free from weeds, and clean for the fucceeding crop of whatever kind it may be*.

The Jiner is another plough, which is ufed for opening ground to a great depth; it is made very ftrong, but with a fhare only, not having any mould-

board; it therefore rather loofens than turns up the earth. In deep ftiff foils, where

the furface mould is good, it may be conveniently employed in the fame furrow af- ter a common plough, in order to ftir the ground to a greater depth. It is in ufe in fome of the northern counties; and Doétor Anderfon mentions it as an implement that all farmers who have land fuitable for it fhould have in their poffeffion. It is an extremely ufeful tool where working deep is neceflary without bringing up the inert under ftratum or fub-foil, as in loofening the ground for carrots, or other tap-rooted plants, and in eradicating the roots of thiftles or other weeds which ftrike deep in the earth.

The Paring-Plough is a neceflary m{trument where the prattice of paring and burning is much required, as in bringing into cultivation heath, moor, and other wafte lands. It is conftru€ted in fuch a manner that the furface of the ground can

be cut off to any depth, which is an advantage that can fearcely be obtained by any other means.
