The sketch shows four houses, 21x18(5, ill the west block, with two 2-inch flows and six 114-inch returns. In the east block there are three houses, 21x100, heated by three 2-inch flows and six 1^4-inch returns in each house. The north block consists of three houses, 21x75, heated by two 2-inch flows and one 11/4-inch flow and by five li/4-ineh rotunis. The south block contains two houses 300 feet long and respectively twenty-eight feet eight inches and twenty-seven feet four inches wide, and heated by three 2-inch flows and six 114-inch returns. Although it may be a little high to rate the boilers at sixty horsepower, they are certainly of fifty-six liorse- power and the two of them should be able to handle tlie radiation for 00,000 square feet of glass, the amount in the houses, as stated in the sketch. For the jmrposes mentioned, 7,;)00 scpiare feet of radiation would be sunicicnt in the northern states, where the tempera- ture drops to 10 to 20 degrees below zero, and more tlian is required in Okla- homa. So far as we can judge from the description of the piping, there is no reason why satisfactory results cannot be obtained, provided sufficient pressure is carried to enable the trap to work. Although a smaller return pipe would answer, we do not think it would help much to make the change proposed and we would advise the carrying of a higher ])ressure in the boiler. To correct the difficulty mentioned, we would place valves on both ends of three of the return pipes in each house, and would take out all but one flow pipe in each liouse. except in the south houses, where two will be needed. It is stated that the boiler is three feet below most of the returns. If this moans that the top of the boiler is three or even two feet below the returns, a by-pass around the trap might be put in, so that a gr
