Gardening; Horticulture; Horticulture; Horticulture. hill. Heated by steam. tory when properly constructed. The side walls should be low and the roof comparatively flat. Usually there is no glass on the side walls. Under most conditions. the house should run north and south, particularly if even in span (Fig. 839), but the lay of the land and the location of existing features usually determine the direc- tion. If the house runs east and west, or if it stands on sloping land (Fig. 840), an uneven or broken span is usually advisable. The widely different opinions re- specting the merits and demerits of the different spans are proof that each is good under certain circumstances. It is the prevail ing opinion that, in broken spans, the long roof should be to the south ; yet some of the best newer houses have the short span — which is then very -^1 steep—facing the south (Fig. 843). In America, all Forcing-h o u s e s are heated by means of small wrought-iron pipes, which fit t o g et h e r with threads.

Each system has its advocates, which means that each has its merits. Steam is less costly to install, since less pipe is required. It also admits of greater variation in the lay-out. Crooks and obstacles are more easily overcome. In a large es- etablishment, the place may be heated up sooner. Hot water gives a milder heat because the pipes are less FORCING hot. Of itsel
