Chap. XXIII. Of f.fe Hoe-Plough, &c. 399 



being at the fame Angles with the Plank as the 

 pricked Line / g, it may be parallel to the Horfe- 

 path, or fo nearly, that by removing the Draw-pin 

 one Hole, it may be made perfectly fo. 



Note, That tho' here are but Nine Holes for the 

 Draw-pin ; yet we ufually make many more in our 

 Planks : And fometimes by changing the Draw-pin 

 either Way into another Hole, tho' that Hole be but 

 an Inch diltanc from the former, the Share is brought 

 right without any Inconvenience. 



The Holes A and C have each of them their oppo- 

 fite Holes, which (when the Beam is placed into either 

 of the Two) have the fame Effecl, for keeping the 

 Share parallel to the Horfe-path, as the Hole B and 

 its Three oppofite Holes have ; and if either of the 

 Holes belonging to A, B, or C, fhould not bring the 

 Beam fufficiently oblique to the Plank, for the Share 

 to be parallel to the Horfe-path, when the Draw-pin 

 is in fome one particular Hole, then there may be an* 

 other Hole bored before, on the Right or Left, for 

 the fore Pin to pafs thro' by the Hole H of the Beam 

 Fig. 2. which will incline the Beam a little more to 

 the Right or Left, as occafion requires ; and if none 

 of all thefe be furncient, the Plank may be turned the 

 other Side upwards *, and the Beam being faflened 

 there by the hinder Screw into any one of thofe Holes, 

 which vvere next to the fore Edge of the Plank before 

 it was reverfed, there may be a new Set of Holes to 

 anfwer the fore Pin, of which that which was an hin- 

 der Hole before the Plank was reverfed, may be one. 

 Thefe may fet the Beam at different Angles from any 

 of the, nrfl Holes ; fo that there may be at one End 

 of the Plank Six Syftems of Holes, Three on the 

 one Side, and Three on the other-, and if we have a 

 mind to make yet more various Pofmons of the 

 Plough, we may turn the Plank, End for End, and 

 there make Six different Syftems of Holes.
