[41] As when Wheat is drill’d late in very poor Land, so that in the Spring the young Plants look all very yellow; let your Hoe-plough, making a crooked Line, like an Indenture, on one Side of a strait Row of this poor Wheat in the Spring, turn a Furrow from it; and in a short time you will see all those yellow Plants, that are contiguous to this Furrow, change their yellow Colour to a deep Green; whilst those Plants of the same Row, which stand farthest off from this indented Furrow, change not their Colour till afterwards; and all the Plants change or retain their Colour sooner or later gradually, as they stand nearer to, or farther from it; and the other Rows, which have no Furrow near them, continue their yellow, after all this Row is become green and flourishing: But this Experiment is best to be made in poor sandy Ground, when the Mould is friable; else perhaps the different Colour may not appear until the Furrow be turn’d back to the Row, having lain some time to be somewhat pulveriz’d (or impregnated) by the Weather, _&c._ This Experiment I often made on Wheat drill’d on the Level before I drill’d any on Ridges. The plowing one Furrow in sandy or mellow Ground makes a Pulveration, which is enjoy’d first by these Plants that are the nearest to it; and also delivers them from the Weeds, which, though there may be very few, yet there is a vast difference between their robbing the Wheat of its Pasture in the Row, and the Wheat’s enjoying both that and the whole Pasture of the Furrow also. I never remember to have seen a Plant poor, that was contiguous to a well-hoed Interval, unless overpower’d by a too great Multitude of other Plants; and the same Exception must be made, if it were a Plant that required more or less Heat or Moisture, than the Soil or Climate afforded. And I have been informed by some Persons, that they have often made the like Observations; that, in the driest of Weather, good Hoeing[42] procures Moisture to Roots; tho’ the Ignorant and Incurious fansy, it lets in the Drought; and therefore are afraid to hoe their Plants at such Times, when, unless they water them, they are spoil’d for Want of it. [42] When Land is become hard by lying too long unho’d, the Plough in turning a deep Furrow from each Side of a single Row of young Plants (suppose of Turneps) may crack the Earth quite through the Row, and expose the Roots to the open Air and Sun in very dry Weather; but if the Earth wherein the Plants stand be fine, there will be no Cracks in it: ’Tis therefore the delaying the Hoeing too long that occasions the Injury. But to hoe with Advantage against dry Weather, the Ground must have been well tilled or hoed before, that the Hoe may go deep, else the Dews, that fall in the Night, will be exhal’d back in the Heat of the Day.
