There is yet one more Benefit Hoeing gives to Plants, which by no Art can possibly be given to Animals: For all that can be done in feeding an Animal is, what has been here already said of Hoeing; that is, to give it sufficient Food, Meat and Drink, at the times it has occasion for them; if you give an Animal any more, ’tis to no manner of Purpose, unless you could give it more Mouths, which is impossible; but in hoeing a Plant the additional Nourishment thereby given, enables it to send out innumerable additional Fibres and Roots, as in one of the Glasses with a Mint in it, is seen; which fully demonstrates, that a Plant increaseth its Mouths, in some Proportion to the Increase of Food given to it: So that Hoeing, by the new Pasture it raises, furnishes both Food and Mouths to Plants; and ’tis for Want of Hoeing, that so few are brought to their Growth and Perfection[43]. [43] A Ground was drill’d with Ray-grass and Barley, in Rows at Five Inches Distance from each other; it produced a pretty good Crop of Ray-grass the second Year as is usual; there was adjoining to it a Ground of Turneps, that were in Rows, with wide Intervals Horse-ho’d; they stood for Seed; and amongst them there was, in Room of a Turnep, a single Plant of Ray-grass, which, being hoed as the Turneps were, had (in every one’s Opinion that saw it) acquired a Bulk at least equal to a Thousand Plants of the same Species in the other Ground; tho’ that vast Plant had no other Advantage above the other, except its Singleness, and the deep Hoeing. I have seen a Chickweed, by the same means, as much increas’d beyond its common Size; and a Plant of Mustard-seed, whose collateral Branches were much bigger than ever I saw a whole Plant of that Sort; it was higher than I could reach its Top, and indeed more like a Tree than an Herb; many other sorts of Plants have I seen thus increased beyond what I had ever observ’d before, but none so much as those. In what Manner the Sarrition of the Antients was performed in their Corn, is not very clear: This seems to have been their Method; _viz._ When the Plants were some time come up, they harrowed the Ground, and pull’d out the Weeds by Hand. The Process of this appears in _Columella_, where he directs the Planting of _Medica_ to be but a Sort of Harrowing or Raking amongst the young Plants, that the Weeds might come out the more easily: _Ligneis Rastris statim jacta Semina obruantur_. _Post Sationem Ligneis Rastris Jarriendus, & identidem runcandus est Ager, ne alterius generis Herba invalidam Medicam perimat._ They harrowed and hoed _Rastris_; so that their _Occatio_ and _Sarritio_ were performed with much the same Sort of Instrument, and differed chiefly in the Time: The first was at Seed-time, to cover the Seed, or level the Ground; the other was to move the Ground after the Plants were up.
