354 Of the meat-Drill Chap. XXI , 



Head of the Harrow with one Hand, and lays the 

 other upon the Hopper, or Spindle, to keep it level 9 

 and to prevent either of the fore Wheels from ftriking 

 agairift the Ground, whilft the Plough is turning 

 round. 



Another Difference there is between the Shape of 

 thele hinder Funnels from that of the former, to wit, 

 That each fore Side of the hinder Trunks muft not 

 be quite ib oblique as the reft-, becaufe then the upper 

 Edge of thele fore Sides might be too near the Tenons 

 of the Sheats, and there might not be fufficient Wood 

 betwixt them, to prevent the Sheats from being torn 

 out j a thing which has never happened, that I know 

 of. We fometimes make thefe hinder Funnels of a 

 roundifh Shape, like a Cone inverted ; except that the 

 Part which is next the Shcat, is not ib oblique as the 

 reft, for the Reafon already given. 



The only Advantage propofed by this roundifb 

 Shape is, that there is lefs Wood taken out than 

 from the fquare Corners, and therefore more Wood 

 for the added Pieces to be faftened to the Beams, than 

 in the fquare Funnels. 



M and N are Two< Pieces of Wood, each Eleven 

 Inches long, Two Inches broad, and Two Inches 

 thick : Thefe are krew'd on near each End of the 

 Plank, by Two Screws and Nuts each: They ftand 

 parallel to the other Beams, and have each a double 

 Standard or Fork, O and P, in them, perpendicular 

 to the Plank -, by which Standards the fore Hopper is 

 drawn and guided, in the manner as is feen in 

 Fig. 21. 



Thefe Standards ought to be braced (or fpurr'd) 

 before and behind, and on their Outfides ; they never 

 being preiVd inwards, have no occafion of Braces 

 there : Thefe are to be fo placed, that when the Spindle 

 is in their Forks, it may be exactly over the Hole of 

 the Funnel, fo that the Seed may drop into the Mid- 

 dle of it, when the Plough ftands upon an horizontal 

 6 Surface,.
