Mr. Buchanan, in his Essay on the Economy of Fuel, relates, that on landing in Ireland, he was much struck with the excellent construction of the fire-grate in the room of the inn where he lodged. He at first thought it was an invention of his landlord's, but on proceeding on his journey, he found the same kind of grates common in that part of Ireland. Fig. 1 represents a front elevation, and Fig. 2 a transverse vertical section of one of these fire-places, which appear well calculated to remedy the smoking of chimneys, and, at the same time, to lessen the consumption of fuel. The fire room is wide and shallow, presenting the greater surface of fire to the room, and thereby radiating the greatest quantity of heat into it. The upper portion of the chimney recess is partly closed by an upright slab of fire stone, in which is cut an arch. The back wall is formed of fire stone, or fire brick, into an oval niche, and the throat of the chimney is made very small to increase the velocity of the air, and thus enable it the better to carry off the smoke.
