Implements of Hufbandry. — Extirpator.

eafily rendered clean and fine by them, and the ufual fubfequent harrowings andploughings be made unneceffary. As the implement of this kind which has beendefcribed above, cannot, as the inventor allures us, be employed except where theground is light, and ££ where the fallow'is well broken, and nearly clean of twitch*,”it may be objected to on that account. But there is, befides this, another objedtionto this fort of tools, which is that of their being liable to clog much when the landis wet, an inconvenience which confiderably leflens their general application. Inthe conftru&ion of the improved Scitfer employed in fome of the midland diftri&sthis inconvenience has how'ever been .attended to, and in a great meafure corre£l:ed.The wheels in this inftrument are made a foot and a half in diameter, and the lengthof the hoes two feet, having a flight curve. It is alfo fo contrived, that it may bedrawn by two horfes abreaft, or at length, as may be found moft proper and con-venient.

The Extirpator is a machine of this fort which feems to be ufed with advantagein fome parts of Suffolk, as well as other counties, for deflroying weeds, and clear-ing fuch lands as have been once ploughed for the reception of the feed. It isdrawn by two or more horfes, according as the foil is more or lefs heavy andtenacious, and as the depth required is greater or lefs. It does much work in a littletime. When employed, it may be fixed to the wheels of a common wheel-plough,and be regulated in refpeft to depth in the fame manner.

If the land has been once ploughed over and laid a fummer fallow, the commonway of proceeding with this inftrument is to work it over twice with it j the firfltime about two inches deep, and the fecond croffways about four inches in depth;which, by afterwards running a common harrow over it, renders it proper for thedrill or fowing. Lands ploughed in Autumn, and intended for fpring crops, mayalfo be well prepared for the feed by this inftrument.

The fhares in this tool are commonly made about nine inches long, and nearly ofthe fame breadth, being attached to a kind Item or fhank of ten inches in length,at the diftance of about twelve inches. It has ledges before and behind ; the firft ofwhich is about five and a half inches long, and the latter fix feet in length, bothhaving the fquare of four inches : the diftance of thefe ledges from each other is ge-nerally about twelve inches. The beam is feven feet in length, having the elevationof about three feet. It has likewife two handles behind.

It is faid to anfwer on all lands, and to be capable of being managed by almoftany ploughman. How far the expeditious way of preparing ground by this tool
