Implements of Hufbandry.—Draining, Marking, Hoeing, Ploughs. 13

The Double Mould-Board-Plough is a kind of plough that may fometimes be employed with advantage in making furrows, and fetting potatoes, cabbages, and other fimilar crops, and in earthing up thofe and other vegatables that are planted in rows.‘The fame purpofe may, however, frequently be anfwered by a plough of a lefs expenfive and lefs complex. kind.

In the furface-draining of land, different forts of ploughs are in ufe in different places, according to the difference of the foils, and the objects of the farmer.

The Common Draining- Plough, which is employed in fome of the midland counties,, for the more general purpofes, is a good, and not very expentfive, tool. And the A/ole- Plough, invented by Mr. Adam Scott, and as improved and made ufe of in the midland counties, is likewife an implement of this kind, which, in fuitable foils and fituations, as in pleafure-grounds, and where much regard is had to the furface- appearance of the'land, may be of confiderable benefit in forming temporary drains. It makes a drain without opening the furface any more than merely for the paflage of a thin coulter, the mark of which foon difappears. This.in{trument is chiefly em-- ployed in fuch grafs-lands a: have a declination of furface, and where there are not. many obftruétions to contend with; but it may be ufed in other kinds of land, as on turnip-grounds that are too wet for the fheep to feed them off, or where on account of the wetnefs the feed cannot be put into the earth. With this plough the: drains fhould be made at the diftance of ten or fifteen feet in ftraight lines,. and: all fo contrived as to difcharge themfelves into one large open furrow, or grip, at the bottom of the field. As it requires great ftrength to draw this implement, it can only be ufed where a good team is kept. It is fuggefted by a very intelligent practical agricultor, that in deep clayey foils it may be highly ufeful, but that where there are beds of gravel or fand intervening, it cannot be employed with advantage.

The Draining-Furrow-Plough is another plough of this clafs, which may be em— ployed for making large open furrows, by which the water may be taken off from the furface of the land. It will frequently be found a neceflary tool in thofe clayey’ foils where water ftagnates on the furface of the ground, and which cannot be re-- moved by the more general: modes of under-draining..

The Marking-Plough is an ufeful inftrument for. the purpofe of ftraighten- ing, as well as regulating the diftance of ridges, where the practice of drilling is in ule.

The Single Hoe-Plough is likewife an implement which, from the great fimplicity of its conftruction, may be of much utility in ftirring the mould in the intervals of grain, or other crops, and laying it to the roots of the plants, thereby deftroying and pre- venting the growth of weeds.. The mould-board in this plough is fo contrived that
