Chap XXI. Of the Wheat-Drill 367 



but it is capable of holding more; but we do not fill 

 it quite, left fome of the Seed fhould fly over in 

 jolting, its Mouth being fo much longer than the 

 other. 



This Hopper is kept in its Place, from moving 

 end-ways upon the Spindle, by a Wreath fixed to the 

 Spindle at each End of the Box, in the fame manner 

 as has been defcribed for holding the other Hopper. 

 The Wreaths moft proper for this Purpofe are the 

 Sort defcribed in Fig. 1 7. but the other Sort defcribed 

 in Fig. 16. and even made with Wood, will fuffice *, 

 but then we muft take care to make the Hole at the 

 End of the Hopper of a confiderable Thicknefs, that 

 it may not wear the Spindle, which, by reafon of its 

 great Length, is the more liable to bend, and be cut 

 by the Edges of the Holes ; which Cutting cannot be 

 prevented but by the Thicknefs of the Holes, or by 

 fuch Wreaths as that of Fig* 17. 



We fometimes make this Hopper exactly like a 

 common Box, without any Part of its Ends defend- 

 ing below the Bottom; and, in that Cafe, we place a 

 narrower Piece of Board at each End of the Hopper* 

 like that of Fig. 23. in which Figure, the Hole A 

 being put on upon the Spindle, the Piece of Board 

 is fattened on by a Screw and Nut thro' the Hole B, 

 near the Top of the End of the Hopper, and by an- 

 other Screw and Nut thro' the Hole C, near the Bot- 

 tom of the Hopper. Another fuch a Piece of Board,. 

 fixed on in the fame manner to the oppofite End of 

 the Hopper, holds this long Hopper parallel to its 

 Spindle, that paries thro' the Holes of thefe Two 

 Pieces, and thro' the Brafs Seed- box, which is fixed 

 up to the Bottom, in the Middle betwixt them. 



There are Two Methods for letting the Seed pafs 

 from a long Hopper into the Seed-box. The firft is 

 that of cutting the Hole through its Bottom, in the 

 manner that has been fhewn in Fig. 14. The other 

 is that which cannot be ufed rn a Hopper fo fhort as
