Chap. XXIII. Of the Hoe-Plough, &c. 395 



End of the Beam, contrary to the manner of placing 

 the Limbers of the Drill Ploughs ; becaufe their Planks 

 being always parallel to the Bottom of their Shares, 

 if their Limbers were parallel to their Beams, as thefc 

 are, the fore Ends of their Limbers would not be 

 elevated higher than the Plank, but would go within 

 a Foot of the Ground, inftead of being elevated 

 almoft as high as the Horfes that draw them ; and 

 the upper and under Surfaces of thL Plank muil not 

 be parallel to the Share, but muft make the fame 

 Angle with it as its Limbers and Beam do. 



Thefe Limbers ought to crook outwards from each 

 other all the Way, till they come within about a Foot 

 of the Chain, much more than the Drill-Limbers 

 need to do ; becaufe the Middle of the Plank of the 

 Drill follows directly after the Horfe, but the Middle 

 of the Plank of the Hoe-Plough very feldom does; 

 and therefore there muft be the more room betwixt 

 thefe Limbers. Likewife there muft be the more room 

 betwixt the fore Part of the Limbers, becaufe often- 

 times the right Limber muft be raifed, and the left 

 depreiTed, in holding the Plough towards the left 

 Side (for if it ihould be held towards the right Side, 

 the Share would go upon the Fin, and its Point be 

 raifed out of the Ground, unlefs it were on a Surface 

 that had a Declivity towards the Right). The Di- 

 ftance between the fore Ends of thefe Limbers is 

 Two Feet Eight Inches. 



The Strength and StifTnefs of thefe Limbers muft 

 be fuch, that there may be no Bending betwixt their 

 fore Ends and the Tail of the Beam -, for if they be 

 too weak, fo as to yield to the Weight of the Furrow, 

 the Point of the Share will defcend into the Ground, 

 and its Tail will rife up, and then the Plough cannot 

 go well. The ihorter they are, the ftronger and 

 ftifter will they be, of the fame Thicknefs. We may 

 make them juft of fuch a Length, that there may be 

 room for the Horfe before the Bar H (which holds 

 the Limbers at their due Diftance), Thefe are from
