In the different experiments to which ears have been sub- 

 jected to determine the quantity by which the right upper 

 iside of the block passes beyond the perpendicular, and to 

 fix the relation between the height and the depth of the 

 furrow, they were made only of wood ; but since my ex- 

 periments have convinced me, that for a furrow 9 inches 

 broad and 6 in depth, the dimensions I have given are the 

 best, I propose in future to have these ears made of cast 

 iron 



I am sensible that this description may appear already too 

 long and too m.inute for a subject which has hitherto been 

 considered as unworthy of furnishing matter of application 

 to science; but, if the plough is really the miplemenfmost 

 useful to man, the improvement of it can r.ever be thought 

 a vain speculation. However, the conibmation of a theory 

 satisfactory to the learned, with a practice which falls within 

 the reach of the most unlettered labourer, must meet with 

 a favourable reception from two classes of men \N'ho render
