t!hap. XXII. Oftk Turnep-DriU. 391 



End of the Carriage, that the Seed may drop on the 

 Side of the Funnel, as is before defcrib'd ; the Box 

 is kept in its Place by one Screw paffing thro' its Back, 

 and the back Side of the Carriage. 



The Notch F is cut in the Bottom of the hinder 

 Side of the Carriage, up to the Bottom of the Led- 

 ger, for the Convenience of feeing the Seed drop into 

 the Funnel. 



The round Notch G is made in the Bottom of the 

 fore Side of the Carriage, to make room for one's 

 Hand to go in there, and turn the Setting-fcrew 

 without taking off the Hopper from the Standards.- 



This Box and Carriage, fo fix'd together, compofe 

 the Turnep-hopper, which is drawn and guided, and 

 alfo holds up the Plough, by' Two hollow Pieces of 

 Wood fcrew'd on to the Outride of the fore Part of 

 the Carriage ; their Ends H and I appearing a little- 

 above the Carriage. 



One of thefe hollow Pieces of Wood is fliewn in 

 Fig. 15. The Breadth of its Hollow mu-ft conform' to* 

 the Breadth of the Standards, Which are One Inch 

 and a quarter broad ; but we mufl allow about a 

 quarter of an Inch more in the Ho!low-for the Swelling 

 of the Wood. The Depth of the Hollow mufl be 

 the Thicknefs of the Standard that is to go in it, 

 allowing about the Eighth of an Inch for the Swelling 

 of the Wood. The HoJlow mould be a little deeper in 

 the Middle than at each End ; becaufe the Standard 

 ought not to bear againft any things except at or near 

 the upper and lower Part of the Carriage. Altho' 

 the End of thefe Pieces come a little higher than the 

 Carriage in this Hopper, yet I think it is better that 

 thefe hollow Pieces come no higher than even with 

 the Top, nor defcend any lower than even with the 

 Bottom of the Carriage; and then the Length of each 

 of thefe Pieces need be no more than Eleven Inches, 

 which is the whole Depth of the Carriage^
