It was, to make an air passage under the whole length of the potato pit, and to have one or two vent holes, or chimnies, on the surface of it. The next thing to guard against was frost, which always descends perpendicularly.
Another cause of smoking is, when the tops of chimnies are commanded by higher buildings, or by a hill, so that the wind blowing over such eminences falls like water over a dam, sometimes almost perpendicularly on the tops of the chimnies that lie in its way, and beats down the smoke contained in them.
This style is even carried where there is not the same natural advantage of a hill to hollow out. The village extends into the plain, which is likewise dug out into subterraneous houses, and which are only visible by the smoke issuing from the chimnies. I could not understand the convenience or necessity for these kind of habitations.
By night, as well as by day, you can have a fire in your room, without a servant being obliged to look after it. Nothing in the thermolampes, not even the smallest portion of inflammable air, can escape combustion; while in our chimnies, torrents evaporate, and even carry off with them the greater part of the heat produced.
According to the old construction of chimnies, this angle is 90 degrees, or forms a right angle; but, as in this case the two covings are parallel to each other, it is evident that they are very ill contrived for throwing into the room, by reflection, the rays from the fire which fall on them.
