. Florists' review [microform]. Floriculture. 78 with the flow, or flows, would be ten 2-inch returns, five of them on each side wall, under the benches. Could I at- tach two 2-inch flows to a Wilks boiler, 24x48? I think this boiler has only one outlet. V. K.—Kan. For a Wilks boiler we would use a 3-inch flow pipe, running it about two feet below the ridge, with the highest point over the boiler. A slope of one inch in ten feet will be ample. When a boiler with two flow ports is used we would, for a house of the stated size and width, run a 2%-inch flow pipe upon each plate or under the purlins. While a radiation of 350 square feet is not too large to be supplied by two 24nch flow pipes, the number of returns necessary will make it advisable to use two 2%- inch flows, unless a single 3-inch flow is used. From the amount of glass stated, we infer that there must be about thirty inches of glass below the plates. If a minimum temperature of 55 degrees is necessary in the coldest weather, it will be advisable to use 350 square feet of radiation, but if it will answer if the temperature drops to 50 degrees in the nights when it drops below zero out- side, 300 square feet of radiation will answer. Instead of running the returns along the side walls only, we would drop down two 21/'-inch pipes from the end of the 3-inch overhead flow pipe, and with each of them feed a coil of five 2-inch flow pipes running each way from the middle of the end of the house to the corners, and then along the side walls, or under the side benches, back to the boiler. It will be found satisfactory to use li/l>-inch returns in a house of this length, and in that case twelve returns will be needed. Hillside, 111.—M. J.
