Another cause is the roughness of the inside of a chimney, or projections which impede the passage of the smoke. Every chimney should be built of equal dimensions from bottom to top, with no projections into it, with as few bends as possible, and with the surface of the inside as smooth as possible.
Another cause of poor draughts is openings into the chimney of chambers for stove-pipes. The remedy is to close them, or insert stove-pipes that are in use.
Another cause is the falling out of brick in some part of the chimney so that outer air is admitted. The remedy is to close the opening.
The draught of a stove may be affected by most of these causes. It also demands that the fire-place have a tight fire-board, or that the throat be carefully filled. For neglecting this, many a good stove has been thrown aside and a poor one taken in its place.
If all young women had committed to memory these causes of evil and their remedies, many a badly-built chimney might have been cured, and many smoke-drawn tears, sighs, ill tempers, and irritating words avoided.
But there are dangers in this direction which demand special attention. Where one flue has two stoves or fire-places, in rooms one above the other, in certain states of the atmosphere, the lower room being the warmer, the colder air and carbonic acid in the room above will pass down into the lower room through the opening for the stove or the fire-place.
This occurred not long since in a boarding-school, when the gas in a room above flowed into a lower one, and suffocated several to death. This room had no mode of ventilation, and several persons slept in it, and were thus stifled. Professor Brewer states a similar case in the family of a relative. An anthracite stove was used in the upper room; and on one still, close night, the gas from this stove descended through the flue and the opening into a room below, and stifled the sleepers.
CHAPTER VI.
ECONOMIC MODES OF BEAUTIFYING A HOME.
The educating influence of works of natural beauty and of art can hardly be overestimated. Surrounded by such suggestions of the beautiful, and such reminders of history and art, children are constantly trained to correctness of taste and refinement of thought, and stimulated—sometimes to efforts at artistic imitation, always to the eager and intelligent inquiry about the scenes, the places, the incidents represented.
