which M/D-uhame'l gives the fbljowing defcHptron, which .we: ill adl 

 copy here for the benefit of fuch as have not a proper drill-p'toughi: 

 efpecially as this inftrument may do very well, where the foil is 

 light, and the extent of knd intended to be fown is not large. , :rl 



It is, as in P/^te IV. Jig. 14, a ftrong kind of rake cc, with four 

 great teeth aa, bb. The diftance from a to a, and from b to b, is 

 nine inches. . M. V'andusfel makes it a foot, becaufe, after his corn 

 ijs.fown, he buries it by drawing a cultivator with two mould boards 

 between the rows. ? f-Kflf^TfiifJi/o'i^c 



; The diftance between the two inner teeth a and b, is three'f^et 

 and a half j. which is the width of. the alleys. 1" 



To the head of this rake c c, are fixed the handles ^, and thfit 

 pole d, which anfwers to the beam of a plough. 



As this inftrument is drawn over ground in fine tilth, and a man 

 prelles more or lefs on the handles e, it forms four fmall furrows 

 f, g, h, t i fo that the furrows / and /j are nine inches afunder, and 

 the furrovvs _g- and / the fame, and a fpace of three feet and a half 

 is left between b and g, for the width of the alley //. In order tO'. 

 preferve the alleys always of the fame width, M. Vandusfel draws 

 the teeth a a in the furrows before made by the teeth bb: fo that 

 the' four furrows are made the firft time this rake is drawn, onlyi 

 two are made each time after. 



Great care muft be taken to make the firft furrows very ftrdit, 

 becaufe the direction of all the others depends on them. 



Women or children drop the feed by hand into thefe furrows, 

 where it is afterwards covered with a harrow, or, as M. Vandusfel 

 has done, with a cultivator with two mould boards, drawn between 

 the two rows, as faft as they are fown. If any part chances not to 

 be covered perfectly by this cultivator, it is eafily done afterwards 

 with a common rake.

Defcrt^tion of M. Duhamel's Drill-Plough. 



Duhamel obferves, that though M.. de Chateau-vieux's drill 

 -" delivers the grain with the greateft exadnefs, and therefore 

 deferves much commendation ; yet the price of it is too great for. 

 moft farmers. M. Duhamel's, which we are going to defcribe, 

 has, for ^hat reafon, been the moft generally ufed. We could wiih 

 that the limits prefcribed to this work would permit us to give alio a
