372. Of the Wheat-Drill Chap. XXI. 



when ufed for drilling of high Ridges, from what 

 would be required when ufed tor drilling low Ridges. 

 One Reafon why the hinder Shares are fhorter than 

 the fore Share (and confequently the lore Part of their 

 Sheatslefs oblique) is, that they maybe fet the nearer 

 to the Plank-, and I have had a Drill with Five Shares 

 in the Plank, Fourteen Inches afunder, and Four of 

 thefe hinder Sheats following in another Rank, whofe 

 Shares werelefs than Three Inches long-, fo that their 

 Beams v/ere fet fo far forwards, that one Hopper (by 

 a Contrivance that carried the Seed forwards to the 

 fore Rank, and backwards to the other Rank) fup- 

 ply'd the Seed to both- Ranks of Trunks, and 

 planted St. Foin in Rows Seven Inches afunder, when 

 the Ground was too rough to be planted with Rows 

 at that Diftance bv one Rank of Shares. 



It may be objected, that the fore Part of thefe 

 hinder Sheats might not be oblique enough to raife 

 up the Strings of Roots or Stubble, which might come 

 acrofs them in their Way ^ but this Inconvenience is 

 remedied by the greater Obliquity of the fore Sheat 

 (or Sheats), which clears the Way for the hinder 

 Sheats, by raifing out of the Ground fuch Strings, &c. 

 which might annoy them ; efpecially, in this Wheat- 

 drill, where the fore Share fo clears the way of the 

 hinder Shares, that they can take hold of no String 

 in the Ground, except of the Ends of fuch which 

 the fore Share has loofen'd; and they hanging fafter 

 in the Ground by their other Ends, the hinder Shares 

 (lip by them without taking hold of them *, and the 

 Harrow-tines, going after fo near to the Chanels of 

 the hinder Sheats, by the fame means efcape alfo 

 from hanging in fuch Strings. 



The Reafons for placing the One Share and One 

 Hopper before, and the Two behind, in this Wheat- 

 drill, are fo many, and fo obvious, that it would be 

 but lofing of Time to mention them.
