Excerpt from The Plough-Wright's Assistant: Or, a Practical Treatise on Various Implements Employed in Agriculture Thus, the construction of those implements, so va lnable, so necessary, and even indispensable to man kind, seems to have been left to persons, most of whom have been ignorant both of their principles and mode of Operation; and though the plough has always held the chief place among the implements of agriculture, yet this valuable machine has been gene rally constructed almost at random, or by guess; few, till of late years, having any fixed plan or pro per rule whereby to Operate. Hence, the forms of ploughs came to be nearly as various, as were the per sons by whom they happened to be constructed.
