3 p i Of the Turnep- Drill. Chap. XX TT 



The Wood on each Side of the Hollow, fufficient 

 for the Holes a, a, a, <z, muft be ab-ut h inch 



broad. The beft way for fixing chem on, is-whiift the 

 Standards are in them, ^taring a fmall Piece of V\ 

 at each Corner of the Hollow, betwixt the Standard 

 3nd the Wood, to the end that there may be no more 

 room on one Side of a Standard than on the other 

 Side; then fcrew them on (parallel to and equidiftant 

 from their refpe&ive Ends of the Carriage) by F r ur 

 fmall Screws each, the one at r, <:, c, <:, and the other 

 at d> d y with Two below •, the Heads of thefe Screws 

 being on the Infide of the Carriage, and their Nuts 

 on the Outfides of the hollow Pieces ; then pull out 

 thofe little Pieces of Wood, that were to ke^p the 

 Standards in tne Middle of the Hollows, whiift the 

 Holes for the Screws were bored, and then the Turnep- 

 Hopper is finifhcd, and being put on upon the Stan- 

 dards A, B, in Fig. 16. is ready to go to Work; 

 and in this figure the whole Turnep^drill may be 

 hec\ as in. the Profpect of a Perfon following it at 

 Work, except that this Figure has not the double 

 Standard, nor Marking- wheels; becaufe we never ufe 

 them for drilling-Turneps, except it be on the Level, 

 "which we very rarely do. 



The Circles of the Wheels of this Hopper go Twenty 

 five Inches afunder ; were they farther afunder, they 

 would not go io well upon the Ridges ; or were they 

 nearer together, they might not hold up the Plough 

 fo fleadily, but that one Wheel might happen to be 

 rais'd from the Ground, by the defending of the op- 

 pofite Limber; and if it fhould happen to be the 

 Wheel that turns the Crank, no Seed would be de- 

 liver'd out whiift the Wheel was rais'd above the 

 Ground ; fometimes we ufe Wheels of Twenty-fix 

 Inches Diameter, fometimes Thirty, and at intermedin 

 #te Diameters, with this Hopper. 



The beft Wood for making all Sorts of Hoppers 

 is Walnut-tree or Elm; our Beams and Standards we
