Fig. 8. is a Sheat with its Trunk and Share of the 

 Drill-plough, which has been defcribed in Plates 4. 

 and /;. but the Shape of the Share, as it rifes at the 

 Socket, is more plainly feen in this Figure. 



Fig. 9. is the whole Wheat-drill, which at prefent I 

 ufe for planting the double Row. A is the Hopper, 

 rifing and finking on the fingle Standard B, which 

 holds it up. C is the thing like the Carrier of a Latch, 

 defcribed by Fig. 22. in Plate 4. I need fay no more 

 for defcribing this Drill, than to mew how it differs 

 from that defcribed in Plate 4. viz. This Hopper 

 has Two of thefe Carriers, the one near its Top, like 

 the others and another near its Bottom, which keeps 

 the Plough from rifing at either End, without the 

 ri{ing of either End of the Hopper, which is no In- 

 convenience here •, becaufe the Two Shares, being 

 but Ten Inches afunder, are almoft the lame as one; 

 fo that at the Diftance the Wheels (land from each 

 other, the rifing of one Wheel doth not lift up the 

 Share that is next to it perceptibly -, as it would do 

 if the Shares were farther afunder, or the Wheels 

 nearer together. 



This Hopper holds twice as much Seed as the 

 fingle fore Hopper did, viz. half a Bufhel ; and is 

 divided into Two equal Parts by the Partition <?, 

 whereby the Driller fees whether the Seed is dif- 

 charged equally ; and if he perceives that one Part 

 of the Hopper runs out fafter than the other, he mufl 

 adjuft them by the Setting-fcrews. 



The Funnels a a, which receive the Seed from the 

 Hopper, and convey it down into the Trunks c c, 

 appear under the Hopper, as doth alfo Part of the 

 Hole i, whereon the Funnel flood when the lore 

 Hopper was fingle. D mews the Cylinder upon the 

 grafted Spindle at one End, as F iliews where the 

 other End with its Cylinder and Wheel is taken off.
