_Dung_ is not injurious to the Fields[20] being there in less Proportion: And the Produce of Corn is the Grain. When the Leaves have done their utmost to purify the Sap, the most refin’d Part is secern’d to be yet further elaborated by peculiar Organs; then, by the Vessels of the Blossoms, ’tis become double-refin’d, for the Nourishment of the Grain; which is therefore more pure from Dung, and more wholsome, than any other Part of the Plant that bears it. [20] Such Plants as _Cabbages_, _Turneps_, _Carrots_, and _Potatoes_, when they are designed only for fatting of Cattle, will not be injured by Dung, Tillage, and Hoeing all together, which will make the Crops the greater, and the Cattle will like them never the worse. And common Tillage alone is not sufficient for many Sorts of Corn, especially Wheat, which is the King of Grains. Very few Fields can have the Conveniency of a sufficient Supply of Dung, to enable them to produce half the Wheat those will do near Cities, where they have Plenty of it. The Crop of 20 Acres will scarce make Dung sufficient for one Acre, in the common Way of laying it on. The Action of the Dung’s Ferment affords a Warmth[21] to the Infant-plants, in their most tender State, and the most rigorous Season. [21] But though Dung in fermenting may have a little Warmth, yet it may sometimes, by letting more Water enter its Hollowness, be in a Frost much colder than undung’d pulverized Earth; for I have seen Wheat-plants in the Winter die in the very Spits of Dung, when undung’d drill’d Wheat, adjoining to it, planted at the same Time, has flourish’d all the same Winter; and I could, not find any other Reason for this, but the Hollowness of the Dung; and yet it seemed to be well rotted. But ’tis hard to know how long the Warmth of this Ferment lasteth, by reason of the great Difficulty to distinguish the very least Degree of Heat from the very least Degree of Cold. Under the Name of Dung we may also understand whatever ferments with the Earth (except Fire); such as green Vegetables cover’d in the Ground, _&c._
