conftruftion or mechanifm. I have likcwifc ob- 

 fcrvcd in the fame place, that the vaft variety of 

 ploughs over all Great-Britain and Ireland, was to 

 nic a convincing proof that none of them were 

 perfedcly good -, for if any one of them had a de- 

 cided fuperiority, it would have been pretty uni- 

 verfally adopted, on fimilar foils. 



xjThis was the ftile of language I ufed frequendy 

 (Q hold with my friend, the Reverend Mr. Cooke, 

 the ingenious inventor of an inimitable drill-plough 

 and horfe-hoe. After many converfations of this 

 kind, Mr. Cooke was induced to turn this fubjedl in 

 his mind, and fome time after (hewed me a model, 

 which I have hinted at in the above-mentioned 

 fedion of my book, as promifing well. Since that 

 time Mr. Cooke has purfued his idea, and, in my 

 opinion, with great fuccefs. In fhort, he got fome 

 bodies of ploughs made of caft-iron, confifting of a 

 mould-board regularly twilled, with the land fide of 

 the plough, and a plug for fixing on the fliare, all 

 iw one piece. This combination of the parts, 

 which fo eflfentially afFed the operation of the 

 plough, prevents the poflfibility of their undergoing 

 any alteration from the unfkilfulnefs of country 

 ploughwrights, who have only to add the common 

 wood-work to thefe caft-iron bodies.
