344 °f the Drill-Boxes. Chap. XX, 



Shilling per Pound, and fo fmooth as to require very 

 little filing. And thefe Brafs Boxes being alfo more 

 lading than Wood, and not much more expenfive, 

 when Workmen know how to make them, 1 think 

 It not worth while to give any particular Directions 

 for making them in Wood. 



As to the Spindles of the Turnep-boxes, I have 

 often made them with a mix'd Metal, of half Pewter, 

 and half Spelter, which perform very well, and are 

 eafily made-, becaufe this Metal will melt, almoft as 

 foon as Lead, in a Fire-fhovel, to be caft in a Mould -> 

 but Brafs will not melt without a Crucible. 



The firfl Idea that I form'd of this Machine, was 

 thus : I imagin'd the Mortife, or Groove, brought 

 from the Sound-board of an Organ, together with 

 the Tongue and Spring, all of them much alter'd ; 

 the Mortife having an Hole therein, and put on upon 

 one of the Iron Gudgeons of the Wheelbarrow ; 

 which Gudgeon being enlarg'd to an Inch and an half 

 Diameter, having on it the Notches of the Cylinder 

 of a Cyder-mill, on that Part of it which mould be 

 within the Mortife, and this Mortife made in the Ear 

 of the Wheelbarrow ("thro' which the Gudgeon ufually 

 paffes), made broad enough for the Purpofe ; this I 

 hoped, for any thing I faw to the contrary, might 

 perform this Work of Drilling ; and herein I was not 

 deceived. 



As for placing a Box over this Mortife to carry a 

 fufficient Quantity of Seed, it was a thing fo obvious, 

 that it occafion'd very little Thought ; and an Inftru- 

 ment for making the Chanels, not much more •, nei- 

 ther for applying Two Wheels, one at each End of 

 the Axis, inflead of the fingle Wheel in the Middle 

 of the Axis of the Wheelbarrow, 



At firft my Plough made open Chanels, and was 

 very rude, being compofed of Four rough Pieces of 

 Planks, of littleValue, held together by Three Shoots, 

 ©r Pieces of Wood, which held them at a Foot Di- 



ftance
