"All Chimney Fire-places, without exception... and even those which do not smoke, as well as those which do, may be greatly improved by making the alterations... here recommended; for it is by no means merely to prevent Chimnies from smoking that these improvements are recommended, but it is also to make them better in all respects... and when the alterations proposed are properly executed, which may very easily be done with the assistance of the following plain and simple directions, the Chimnies will never fail to answer... even beyond expectation. The room will be heated much more equally and more pleasantly with less than half the fuel used before, the fire will be more cheerful and more agreeable; and the general appearance of the Fire-place more neat and elegant, and the Chimney will never smoke."
