In case the Shares, being only Three, should in fine Ground go so deep as to endanger the Burying of the Seed, the best Remedy to prevent this fatal Misfortune is, to place a triangular Piece of Wood, like those in _Figures_ 25. and 26. the first of which shews one Side thereof, with the Nail by which it is to be nail’d into the lower Part of the Trunk, with, its most acute Angle uppermost; the other in _Fig._ 26. shews the same, and its Back-side _a b_, that is to be nail’d to the Back of the Shear, being of the same Breadth with it; its Bottom _b c_ being the Breadth of the Plates, on their Inside, the Angle _c_ coming out backwards, just as far as the Plates: The Depth of this Piece from _a_ to _c_ is uncertain, because the Plates of some Trunks are broader than of others. The Use of this Piece is, to fill up the lower Part of the Trunk; so that the Seed, dropping upon the oblique Side of this Piece of Wood, may by it be turn’d into the Chanel, after so much Mould is fallen in it, as will sufficiently lessen its Depth, whereby the Danger of burying the Seed is avoided: And such a Piece of Wood placed into each Trunk, I think, is preferable to Ground-wrists, which are commonly used for this Purpose; because the Ground-wrists leave the Chanels too wide and open. But when only the Two hinder Sheats are used for St. Foin, we can make their Chanels the shallower, by sinking the Limbers by their Chain, so much as that, the Plough bearing most upon the fore Share, the hinder Shares will go the shallower. When we drill hilly Ground, both up and down, we cover the hinder Parts of all the Trunks, from their Tops, to within Two or Three Inches of the Ground, to prevent the Seed’s falling out far behind the Trunk, in going up Hill; and this we do either by a Piece of Leather nail’d to each Side of a Sheat, the Middle of the Leather bearing against the hinder Part of the Plates (or Trunk); or sometimes, instead of Leather, we use Tin. Every Trunk being thus inclos’d behind, we can drill up and down an hill of a moderate Ascent; but when it is very steep, we never drill any thing but St. Foin on it, and that by a Drill made for the Purpose, so very light, that a Man may carry it up the Hill on his Back, and draw it down after him: This Drill has Five or Six Sheats in one Row (with the Harrow behind them). Their Shares being extremely short, the Standards which draw the Hopper must be set perpendicular to the Horizon, when the Drill is coming down, rather than to the Surface of the Side of the Hill: The Funnels must also correspond with the Standards. Some, instead of these Sheats, make use of hollow wooden Harrow-tines, thro’ which the Seed descends: But these I do not approve of; because where the Ground is hard, and not fine, they rise up, and make no Chanels for the Seed; and then it lying uncover’d will be malted.
