A Second Objection is, That as Hoeing makes poor Land become rich enough to bear good Crops of Wheat for several Years successively, the same must needs make very good Land become too rich for Wheat. I answer, That if possibly it should so happen, there are Two Remedies to be used in such a Case; the one is to plant it with Beans, or some other Vegetables, which cannot be over-nourished, as Turneps, Carrots, Cabbages, and such-like, which are excellent Food for fatting of Cattle; or else they may make use of the other infallible Remedy, when that rich Land, by producing Crops every Year in the Hoeing-Husbandry, is grown too vigorous and resty, they may soon take down its Mettle, by sowing it a few Years in their old Husbandry, which will fill it again with a new Stock of Weeds, that will suck it out of Heart, and exhaust more of its Vigour, than the Dung[255], that helps to produce them, can restore. [255] Dung made of the Straw of sown Corn generally abounds with the Seed of Weeds. There is a Third Objection, and that is, That the Benefit of some Ground is lost where the Hoe-plough turns at each End of the Lands: But this cannot be much, if any, Damage; because about Four Square Perch to a Statute Acre is sufficient for this Purpose; and that, at the Rate of _Ten Shillings_ Rent, comes to but _Three-pence_, tho’ this varies, according as the Piece is longer or shorter; and supposing the most to be Eight Perch, that is but _Six-pence_ _per_ Acre; and that is not lost neither; for whether it be of natural or artificial Grass, the Hoe-plough, in turning on it, will scratch it, and leave some Earth on it, which will enrich it so much, that it may be worth its Rent for Baiting of Horses or Oxen upon it. And besides, these Ends are commonly near Quick-hedges or Trees, which do so exhaust it, that when no Cattle come there to manure it, ’tis not worth the Labour of plowing it. CHAP. XVIII. _Of_ PLOUGHS. By what means Ploughs and Tillage itself came at first to be invented is uncertain; therefore we are at Liberty to guess: And it seems most probable, that it was, like most other Inventions, found out by Accident, and that the first Tillers or Plowers of the Ground were Hogs: Men in those Days, having sufficient Leisure for Speculation, observ’d, that when any sort of Seed happen’d to fall on a Spot of Ground well routed up by the Swine (which Instinct had instructed to dig in Search of their Food), it grew and prospered much better than in the whole unbroken Turf. This Observation must naturally induce rational Creatures to the Contrivance of some Instrument, which might imitate, if not excel Brutes in this Operation of breaking and dividing the Surface of the Earth, in order to increase and better its Product.
