Finlayson's harrow, invented in the neighbourhood of Ayr; by a farmer of that name, a most ingenious and excellent man, who, unfortunately, did not live to see the effects, and reap the fruits, of his invention, is also very generally used; and we have been informed by several farmers, and particularly by our esteemed friend, Mr. Tenant of Shields, that, in consequence of employing this implement, they never plough their turnip, potato, or other fallows more than twice; viz., in preparing the ground, to break up the stubble; and, before sowing or planting, to form the drills. In naked fallows, the plough is only used at first breaking up, and in turning in the manure before sowing.
