I should like to pipe it with 1^-inch pipe for the re- turns. Would one 2-inch flow supply them? Please tell me how many pipes will be needed, their sizes and how to arrange them. The boiler will be about forty feet from the near end of the pro- posed house. I should like to have the house of a width to take four lights of 24-inch glass on each side, with no side lights. The roses may not pay, so I want to build as cheaply as possible and be nearly right. I ^m located in northern Nova Scotia. W. C. More satisfactory results, of course, could be obtained in a larger house, but, if it will not be possible to erect one more than twenty-five f ^t long, a width of fourteen feet would answer to carry out the arrangement suggested. The middle bench could then be four feet wide, which would answer for either three or four rows of plants. A distance of one foot each way does well for roses, but it may be a little more or less than that distance, according to the varieties, size of plants, etc. Either use one 21^-inch flow pipe under the ridge, or one 2-inch flow upon each side plate. If 1%-inch pipe is used for the returns, five under each of the side benches will be required. In case the farther end of the house is ex- posed, the return coils should start at the middle of the end of the house and follow around the walls along each side. If you can place the coils at least three or four feet above the top of the heater, and if there is no door in the farther end of the house, the use of overhead flow pipes may be dispensed with. Merely run a 2V^-inch flow to the near- est corner of the house and connect it with a coil of six 1%-inch flow pipes, which should be carried around three , sides of the house and then connected with the boiler by means of a 21^-inch return. A SMALL DAKOTA HOUSE. I am preparing to build a greenhouse,
