1 . Ploughs.

In describing the machines and instruments now made useof for cultivating the ground in the more improved districtsof North Britain, it is proper to begin with the plough, asbeing the first of chief of all the implements employed in theextensive art of agriculture. There are several instrumentsemployed in husbandry which perhaps might be dispensedwith, but land can hardly be cultivated to advantage, at leastto apy considerable extent, without the plough.
