A. A hot room is cooled more quickly by opening the lower sash; because the cold air can enter more freely by an under current, than by one higher up.
Q. Why does wind dry damp linen?
A. Because dry wind (like a dry sponge) imbibes the particles of vapour from the surface of the linen, as fast as they are formed.
Q. Which is the hottest place in a church, chapel, or theatre?
A. The gallery.
Q. Why is the gallery of all public places hotter than the lower parts of the building?
A. Because the heated air of the room ascends, and all the cold air (which can enter through the doors and windows) keeps to the floor, till it has become heated.
Q. Why do plants often grow out of walls and towers?
A. Because sometimes the wind blows the seed there with the dust; and sometimes birds (flying over) drop the seed which they had formerly eaten.
