The annexed diagram will show the system to be employed much better than words can explain. We can refer to many florists who will testify to perfect success in heating their houses by this arrange- ment of pipes and boiler. After the pipes enter the greenhouse the same plan of laying them may be adopted as if the boiler was below the ground line. If the radiating pipes have a rising incline through the length of the line a vent pipe must be inserted at the highest point reached, but if the pipes have a gradual fall through flow and returns back to the boiler, no vent, stand pipe or expansion tank will be needed, save those shown near the boiler.

The sliding ventilator has an advan- tage over one which is lifted from the fact that it is not so liable to catch the wind; lifting a ventilator from the up- per instead of the lower end obviates this defect of lifting ventilators to a con- siderable extent, but not entirely.
