This is a representation of one of the American ploughsexhibited at the Great Exhibition of all Nations, and whichexcited great interest among agriculturists who saw them. They are said to possess peculiar advantages in the localityof the lands they are intended to break up ; but they are not PLOUGHING BY STEAM. 55 available here in any way that I am aware of, though I observeone house advertises to supply English farmers with these Fig. remarkable implements. I doubt much whether any onewho has seen the ploughs of our best makers will ever bepersuaded to buy them, so utterly different are they to allthose notions which we are agreed about in reference toploughs. Some very ingenious implements were exhibited never-theless—one, in particular, which was so constructed thatthe mould-board turned underneath and adapted itselfequally well to one side or the other; and, among others,one which has chisel-headed shares, which could be pro-truded forward as it wore away, being thus always self-sharpening. This principle might be applied with advantageto ploughs intended for the colonies. PLOUGHING BY STEAM Has not yet been brought to such a state as to be appli-cable to ordinary practice. A number of gentlemen have,at different times, brought forward plans for ploughingby steam, and, much to their honour, have given the differentmethods a fair trial without regard to the expense;
