Till this very useful machine wasinvented, it was exceedingly difficult to compare the draught of differentploughs, as there was no rule to judge by, but the exertions of the horsesas apparent to the eye; a very undecisive mode of ascertaining their Brabys draught-machine (Jig. 275.), consists of two strong steelplates, joined at the ends, and forming a spheroidal opening between them,it, one end {a) is hooked on the muzzle of the plough or other implement,and to the other (6) thedraught trees are at-tached. An indicator(c) points out the powerapplied, in cwts. It isevident that Brabysmachine and Finlay-sons act on the sameprinciple, and that thelatter, being more simple in the construction, mustbe a more accurate indic
