A modern floricultural establislmient. (Pierce Bros., Waltham, Mass.) pipes also can be much smaller than with hot water, a two and one-half-inch pipe being amply large for a house 20 by 100 feet. Two methods are commonly used for arranging the steam heating pipes in greenhouses. In one, the flow-pipe is carried to the farther end of the house where it is joined by means of branch pipes to the coils, which are distributed about the same as with hot water. The other way is to connect the flow pipes with the coils at the end nearest the boiler. Each of the coils may be provided with a return pipe for the drip, or all of the coils may be connected at the farther end of the house with one pipe which serves as a common return pipe for the series. Literature. Greenhouse Construction and Greenhouse Man- agement (two books), L. R. Taft, Orange Judd Co., New York. For chapters on the building and care of greenhouses, see also Gardening for Pleasure, Peter Henderson ; Success in Market Gardening, W. W. Rawson ; Vegetable Gardening, S. B.
