quite fo much : fo that the diftance from C to D, Jig. i6, may be 

 twelve or thirteen, and. even fifteen 'or fixteen inches. This fame 

 cultivator may likevvife he ufed in frifF lands. 



Nothing hinders making thefe mould-boards two or three inches 

 longer, from B to G, and from E to H; nor varying fome of their 

 proportions, as the plowman may like beft. 



This {have, with the mould-boards, is fixed to a beam, as in the 

 fingle cultivator fig. 2, where it is faftened to the fore carriage by the 

 crofs ftaves I, L. 



If this defcription does but convey a fufiiciently clear idea of the' 

 fliape and proportions of this cultivator, I will anlwer for its fuccefs 

 when ufed. I dcfcribe it after one of the fame kind, which I have 

 made ufe of for two years part, with very great fuccefs. .'-- ■;'•'-■■'

M. de Chateau-vieux. 



1 N my account of the experiments of 17535 I f^iid that this culti- 

 ■■• vator opened the great furrow in the middle of the alley, by 

 turning the earth over on both fides at the fame time; and that as 

 much work was done by that means, by one turn of this inftrument, 

 as could be done by two, and frequently three turns of the common 

 plough, and that without ufing a greater number of cattle. I muft 

 now prove this propofition ; tho' I am perfuaded that it will eafily be 

 allowed by whoever only cafts an eye on Jig . 16. Plate^Y, which 

 reprefents the fhare of this cultivator. 



The vacant fpace between the outmofl: row of corn on one bed, 

 and the neareft row to it on the next parallel bed,which is what we 

 have called the alley, and which is not fown at all, is the part that 

 is to be cultivated at different times, from thefirft fprouting of the 

 com, till it is ripe. 



The pradice of the new hufbandry has already fliewn fufficiently, 

 that too narrow alleys would fcarcely anfwer any of the ends they are 

 intended for; and that making them too wide, is a lofs of ground. 

 About four feet, exclufive of the fpaces or partitions between the • 

 rows of corn in the beds, is a good middling width. 



It is lefs neceflary to make the alleys quite fo wide in good foils ; 

 nor indeed do I think four feet fo abfolutely necefi^ary at any time, 

 but that a few inches lefs may do. An intelligent hufbandman will 

 eafily judge what is mofl proper to be done in this refpedt. But
