The ashes fall through a grating into a receptacle which may be emptied daily, or are conveyed through an iron pipe into a close brick chamber in the cellar, to be removed once a year. By this contrivance the feet are easily warmed, and are kept so; there is no danger of the coals falling on the floor or carpet, and the fire is made to burn more or less fiercely as easily as in an air-tight stove. This is written after a winter’s trial. At an expense of less than three tons of coal, or two hundred and forty bushels, the thermom- eter on the wall opposite to the fire place, in a room two hundred and fifty feet square and twelve high, was kept at sixty-five degrees when the mercury was in the neighborhood of zero without, the heat being derived from a broad bed of glowing coals over two feet long. These coals being on a level with the floor, keep the feet delightfully warm. The air for com- bustion is obtained from the cellar or the street; hence the atmosphere of the room is simply pure air warmed, and has the genial heat of a wood-fire; hence, also, there is none of the feeling of heaviness, sultriness, and oppression
