Floriculture. pr.'T"--^.-' IS •' *j»^:7' The Florists' Review OCIOBKH 2a, 1!J14 under the ridge north end and connect it with eight 1^-inch returns, four of which should be placed under each of the side benches. The location of the doors will perhaps have something to do with the arrange- ment of the piping in the other part of the house, but I would run a 2i^-inch main to the west end and, after drop- ping it down, connect with coils run- ning across the west end and down the side walls. About 400 lineal feet of 1%- inch pipe will be required to heat this part of the house. If there are no doors to prevent the carrying of the coils along the exposed walls of the four sides of the room, five lines of 1%-inch pipe will answer for each of the coils, but if only a portion of the walls can be utilized, the number of pipes in the coils should be proportion- ately increased. If the boiler, as seems to be indicated by the sketch, can be placed only five feet in the ground, the use of 1%-inch pipe for the returns is not advisable without using some fqrm of circulator or generator. While one section of the sketch of the main part of the house shows five feet of space on one side of the ridge and nine feet on the other, making a width of fourteen feet, as already stated, yet the ground plan shows a width of twenty-two feet. For this width two additional return pipes will be required in each coil. I would pre- fer to use four 2-inch pipes or two 3-inch pipes where I have suggested using four 1%-inch returns. SCARCELY ENOUGH PIPING. We are building a greenhouse, 42i/^x 150. It is of iron-frame construction, with concrete walls and with thirty-six inches of glass in each side. In this part of North Carolina the outside tem- perature rarely drops lower than 15 de- grees above zero; perhaps once in a few years it falls to 5 or 6 degrees above zero. We are planning to heat the house with two 2-inch mains, one 2i/^-inch main and eight
