Hothouse paths

2169. The paths in hothouses vary in direction, breadth, and construction. In general, one path runs parallel to the front, sometimes upon the front flue, but more generally beside it; at other times, as in peach-houses, it passes near the back wall, or through the middle of the house. In pineries and houses with pits, it generally surrounds these; and in greenhouses it is commonly confined to a course parallel to the front and ends.
