As the Ridges may be much lower that have only the one Partition, so the Intervals may be narrower, and yet have as much Earth in them to be pulveriz’d, as in wide ones that are betwixt treble Rows; because the Four Inches that are in the two Partitions more than in the single Partition, being on the Top of the Ridge, may have more Mould under them than Eight Inches on the Side of a Ridge; and the Four Inches, being in the Partitions, lose the Benefit of Horse-hoeing. Instead of using the middle Row as an Alloy, ’tis better to plant such Sorts of Wheat as do not require any Alloy to the double Row; and these are the _White-cone_, and above all other Sorts the right _Smyrna_. The _White-cone_ Wheat must not be reaped so green as the _Lammas_ Wheat may; for if it is not full-ripe, it will be difficult to thresh it clean out of the Straw. It happened once that my _White-cone_ being planted early, and being very high, the Blade and Stalk were kill’d in the Winter; and yet it grew high again in the Spring, and had then the same Fortune a Second time; it lay on the Ridges like Straw, but sprung out anew from the Root, and made a very good Crop at Harvest: Therefore, if the like Accident should happen, the Owner needs not be frighted at it. One thing that made Six-feet Ridges seem at first necessary, was the great Breadth of the Two Partitions (which were Eight Inches apiece), which, together with the Earth left on each Side of the treble Row not well cleansed by Hand-work, made Two large whole Furrows, at the first Plowing for the next Crop, that could not be broken by Harrows: These Two strong Furrows, being turned to the Two Furrows that are in the middle of a narrow Interval, for making a new Ridge, would cover almost all the pulveriz’d Earth, not leaving room betwixt the Two whole Furrows for the Drill to go in. But now the single Partition, and the Earth left by the Hoe-Plough, on the Outsides of the double Row, making Two narrow Furrows, and the one Partition being cleansed, and deeper Hand-ho’d than those of the treble Row were, or could be, are easily broken by the Harrows; for, besides their Narrowness, they have no Roots to hold their Mould together, except the Wheat-roots, which, being small and dead, have not Strength enough to hold it; and therefore that Necessity of such broad Ridges now ceases along with the treble Row. When the Two narrow fragile Furrows are harrowed, and mixed with the pulveriz’d Earth of the Intervals, the Roots of the Wheat will reach it; and it is no Matter whether the Crop be drill’d after Two Plowings, in which Case the Row will stand on the very same Place whereon the Row stood the precedent Year, or whether it be drill’d after One or Three Plowings; and then the Rows will stand on the Middle of the last Year’s Intervals.
