I cannot prescribe precisely the most proper Width of all Intervals; because they should be different in different Circumstances. In deep rich Land they may be a little narrower than in shallow Land. There must be (as has been said) a competent Quantity of Earth in them to be pulveriz’d; and, when the Soil is rich, the less will suffice. Never let the Intervals be too wide to be Horse-hoed at Two Furrows, without leaving any Part unplowed in the Middle of them, when the Furrows are turned towards the Rows. Some Ploughmen can plow a wider Furrow than others, that do not understand the letting of the Hoe-Plough so well, can. By making the Plank of the Hoe-plough shorter, and the Limbers more crooked, we can now hoe in narrower Intervals than formerly, without doing any Damage to the Wheat. I now choose to have Fourteen Ridges on an Acre, and one only Partition of Ten Inches on each of them. This I find answers all the Ends I purpose. If the Partitions are narrower, there is not sufficient room in them for the Hand-hoe to do its work effectually; if wider, too much Earth will lose the Benefit of the Horse-hoe. The poorer the Soil is, the more Pulveration will be necessary to it. When a great Season of Wheat is drill’d, it cannot be expected that much of it can be plowed dry, tho’ it is advantageous when there happens an Opportunity for doing it; but by long Experience I find, that in most of my Lands it does very well, when plowed in a moderate Temper of Moisture. It may not be amiss to harrow it once after it is drill’d, which will, in some Measure, disappoint the Rooks; besides covering the Wheat, if, perchance, any should miss being covered by the Drill-harrow. But these, and all Harrows that go on a Ridge, both before and after it is drill’d, should be very light, and fastened together in the common Manner; except that the Pole must be fastened to each Harrow in two Places; which keeps them both as level as if they were One single Harrow: Otherwise the Ridges would be too sharp at the Top, and the Partitions would lie higher than the Rows, and some of their Earth would be apt to fall on the Rows when it is Hand-hoed. By Means of this level Harrowing, there is left an open Furrow in the Middle of the Interval, which much facilitates the First Horse-hoeing. But when, after a Crop is taken off, the Ridges are plowed twice, as they may be where the one Partition hath been well Hand-ho’d; ’tis better to harrow the first-made Ridges in the common Manner; because then some of the fine Earth, that is harrow’d down, will reach to the middle of the Intervals whereon the Ridges are to be made for Drilling: Or if there should be time for plowing thrice, the Ridges of the First and Second Plowings are to be harrow’d in the common Manner also. The Harrowing of Ridges must never be cross-ways, unless they are to be made level for Cross-plowing, in order to lay out the Ridges of a Breadth different to what they were of before.
