IMPLEMENTS. 55 



for want of the force exerted being accurately ascertained, 

 these experiments have not been attended with the con- 

 viftion which might have been the consequence. 



From the preceding minutes it appears, that some 

 doubts have acSluaHy been entertained, by very able and 

 practical farmers, on the usual btrudlure of this plough ; 

 and Mr. Reeve, varying the form in tlie length of beam 

 and the mould-board, when he wants to ivhelm the fur- 

 row well (that is, turn it completely over), confirms the 

 propriety of our considering the struftuie of this plough 

 as not well ascertained. 



In addition to this observation i have to remark, that in 

 passing through almost every part of the county, I never 

 omitted any opportunity of following ploughs at work, 

 and noticing their steadiness and other circumstances ; and 

 I remarked two very deficient points — they do not gene- 

 rally go close at heel ; and when I desired the men to 

 quit their held, and let the jilough go alone, not one in 

 twenty woukl do it, even for a single rod ; now, a ivheel' 

 plough must lie badly constructed that will not stand this 

 trial, which, for a short distance, is perhaps the best 

 criterion of a swing-plough. 



I have an high opinion of the Norfolk plougli, when 

 well construdled, and offer these i-emarks merely to insti- 

 gate the gentlemen of the county who take any pleasure 

 Tn rural mechanics, to ascertain these circumstances by 

 experiments which are not difficult to make, and would 

 tend powerfully to give the wheel 'a rights and blacksmiths 

 more certain rules to work by, than they possess at pre- 

 sent. 



HARROWS. 



Mr. Johnson, of Thurning, thinks that it is common 

 lo put too many teeth in harrows : he chuscs to have his
