These Limbers should approach so near together at their fore Parts, near the Chain, that there may be none or very little room betwixt the Limbers and the Horse; and therefore must be nearer together for a very little Horse than for a great one: The Horse, which I have used in all my Drills for these many Years past, is a little one, about Thirteen Hands high; and the fore Part of my Drill-limbers are Twenty Inches wide asunder at the Chain. At _g_ on the Outside of the Limber G, is a small Staple driven in, having one Link on it, which holds a small Hook, which, taking hold of different Links of the very small Chain I, raises or sinks the fore Part of the Plough to different Heights. But take care to set it at such a Degree, that the fore and hinder Share may go equally deep in the Ground; and when they do so, the fore Part of the Limbers ought to be higher than the Traces which draw them. At _h_ in the Limber H, is driven another Staple, which holds the other End of the Chain; or else, instead of a Chain, we may make use of a Piece of Cord, one End of which put thro’ this Staple, and ty’d to the Limber, and a Piece of Chain of half a dozen Links, fasten’d to the other End of such a Cord, will serve as well as a whole Chain, for raising and sinking the Limbers. He who can by these Directions make this Wheat-drill, may very easily make any other Sort of Drill, for planting any Sort of Corn, or other Seeds that are near about the Bigness of Seeds of Corn: He may make it with a single Row of Sheats, by placing as many of these fore Sheats as he pleases in the Plank, which maybe longer or shorter, as he thinks fit; and he may add a Beam betwixt every Two of them, with a Sheat in it, like these hinder Sheats; and then the Drill will be double, having Two Ranks of Shares. But I must advise him never to make a Drill with more Shares than will be contain’d in Four Feet Breadth, that is, from the outermost on the right Hand, to the outermost on the left Hand; for should the Drill be broader, some of the Shares might pass over hollow Places of the Ground without reaching them, and then the Seed falling on the Ground would be uncover’d in such low Places.
