On chimney placement:
“chimneys in the interior of a house …draw better than in the exterior walls, [and it is] more pleasing to see the chimney tops rising from the apex, or highest part of the roof…”
—A. J. Downing
“Now as a good draught depends, in a great degree, on the warmth of the column of air, and this upon the heat of the chimney, it is evident that chimneys in the interior of a house must draw better than in the exterior walls.
Besides this, a great deal of heat is retained in the body of the house by carrying the stacks of flues through it. And in point of external effect, it is much more pleasing to see the chimney tops rising from the apex, or highest part of the roof, than from its lowest edge.”
