_Fig._ 4. shews the manner how the Hoe-plough is drawn, and how the Traces are fix’d to it. The Traces of both Horses are fastened to the Notches of the Ends of the Whipper at _a_ and _b_. The Traces of the Thiller by their fore Part are fastened to an Hook, or Ring, on the Wood of the Collar, as is usual for other Thillers; and the fore Part of the next Horse’s Traces is fastened to his Collar in like manner; but these Traces, being twice as long as those of the Thiller, must be held up in the Middle by a Piece of Cord or Chain, as at _c_, where one End of it is fastened to the Trace, and passes over the Top of the Collar, behind one of the Hames, and before the other to keep it from slipping backwards or forwards; its other End is fastened to the opposite Trace on the other Side, as this End is at _c_. This prevents the Chain from falling down, and getting under the Horse’s Legs in turning; but beware that this String or Chain be not so short as to hold up the Traces higher than their strait Line; for that would press upon the Collar, and gall the Thiller, besides occasioning the Plough to be drawn too much upwards; for this drawing of the fore Horse by a different Line from that of the Thiller, is a great Advantage for keeping the Plough the firmer into the Ground. If there is another Horse, his Traces are fastened at the Collar of the Second, in the same manner as in drawing of a Waggon. When we hoe betwixt Rows, where the Plants are very high, as those of Turnep-seed, which are much higher than the Horses, to turn a new Furrow up to the Row, when there is a Trench in the Middle of the Interval, where the Horses must go, we find it best to place the Beam by the Holes B and E, in _Fig._ 3. and the Draw-pin near the left Limber, which brings the Tail of the Plough to the Right-hand, and the fore Ends of the Limbers being towards the Left, the End of the right Limber (by turning the Handles a little to the Left) bears against the wooden Saddle at _d_, and cannot hitch into or take hold of any of the Plants to tear them. And that no Part of the Limber may take hold of any Plant, we make it very smooth from one End to the other; and cut off the Corner of the Plank equal with the Limber, that the Plants may slip by it without hanging in it, or being broken by it. The Whipper standing towards the left End of the Plank, its End _b_ does not reach so far towards the right as to take hold of the Plants, its End _a_ being over the Interval, where no Plants are; and to keep its right End the more out of Danger of hurting the Plants, we place the Hook of its Chain nearer towards this End, by which means the left End, becoming heavier, sinks lower, and raises the right End higher; and the higher it is, the more secure the Plants will be from it; because they are held off by the Limber above.
