juft as the intended plowing may require. The fhare and its handle 

 enter {o deep into the earth, as to be quite buried in it, if a deep 

 plowing is intended to be given : and in that cale the tail y^ of the 

 |>eam touches the ground. Tho' the fhare is but fmall, it llirs the 

 earth at leait a foot round it : its point fliould be of llieel, and fonie- 

 what. inclined to\yards the earth. 



The fliare of this inftrument,' like that of the plough, may be 

 brought as near as one pleafes to the rows of corn, by plackig the 

 beam accordingly in the frame.

npH IS inftrument 7%-. • 13 and 14, has two fliares. It has sc 

 -■■ beam A B, and the lliares CD, EF, which being exadly like 

 that of the fmgle cultivator, we have only to point out wherein thefe 

 inftruments differ. The beam of this Ihould be 10 or 12 inches 

 longer than that of the other. It has likewife two mortifes more, 

 under the letters G and H, to let through the crols Haves E K, I L, 

 which bear the handle M N, OP of the fhares. The crofs 

 ftaves EK, IL, are rivetted permanently to the beam: the handles 

 MN, O P, are moveable upon the crols ftaves, to which they are 

 faftened by the keys R, S, ^ T; fo that the Ihares may be let at a 

 greater or lefs diftance from each other, according as the quality or 

 lituation of the ground may require or allow. 



This inftrument ftirs the earth extremely well,, and does a great 

 deal of work in a little time. Each Ihare being about fifteen inches 

 wide at ^C, BD, Jig. 1^, and the diftance between them from 

 A to B, Jig. 15, being about four inches, or, upon occafion, fix; 

 and the earth being ftirred about two inches on each fide beyond the 

 extent of the outmoft fins of the fhares ; each cut of this cultivator 

 ftirs about two feet breadth of ground. This double cu-ltivator re- 

 quires two horfes, unlels the foil be very light ; in which cafe, 

 M. de Chateau-vieux thinks one may do, tho' he lays he has not yet 

 tried it. 



If one had a mind to fix, a coulter in the middle of the beam, 

 Jhft before the fliares, we fee no inconveniency that could attend it, 

 provided it be a very light one. 



The way to ufc this cultivator, is to faften it to the fore-carriage
