5;o Of the Drill-Boxes. Chap. XX, 



tife of the Seed-box, The left Flank B, being next 

 the wide Side of the Hopper, lies all open, except on 

 the outfide of the pricked Lines, where it is covered 

 by the Wood of the End of the Hopper, when it is 

 fcrewed on to its Place ; but the Plapch C, on the 

 right Side, will be all covered by the End of the 

 Box, that will ftand upon it, and will reach to the 

 pricked Line that touches the Edge of the Mortife. 

 E) is the End of the Setting-fcrew, appearing in its 

 Place with a Notch, whereby it is to be turned by a 

 Knife ; but I think it better to have an End like a T, 

 to be turned with the Fingers. E is one End of the 

 hollow Cylinder, which projects beyond the Flanch, 

 that there may be more Room for the Crank to turn 

 (without ftriking againft the End of the Hopper, or 

 againft the Flanch) on the Outfide of the Box or 

 Hopper \ and for that, the longer this Cylinder is, 

 the better the Brafs Spindle will turn in it. 



Fig. ii. is the Spring-cover, with its Hole, where- 

 by it is fcrewed into its Place, as it is (qqh marked A % 

 in Fig. 9. 



Fig. 12. is the Setting-fcrew pointing againft its 

 Hole, its Head being flat, that it may be turned by 

 the Finger and Thumb. 



Fig. 13. is the Counter-fcrew, to be turned in the 

 fame manner. 



Fig. 5. fhews the Brafs Spindle of the Turnep 

 Seed-box, and the Manner of turning it againft its 

 Steel Tongue, or Spring ; which Manner is different 

 from that of turning the larger Spindles for Boxes 

 of a larger Size, fuch as the Wheat Seed-box. 



This Spindle (a), being but half an Inch Diameter, 

 is too fmall to be turned by the Two Wheels, as, 



the 



(a) I believe, if it were lefs by a Fourth or Third of its Di- 

 ame:er, it might be better, as being more proportionable to the 

 Smalnefs of the Turnep-feed. I have had the Mortife much 

 wider ; but it cannot well be made much narrower. wHilil the
