Do you think two 2^-inch flow pipes overhead, ?with six 2-inch returns, would be suffi- cient to hold a temperature of 55 degrees here, in southwest Missouri? O. C. M.—Mo. There should be no difficulty in heat- ing the house described to 55 degrees with two 2iA-inch flow pipes and six 2-inch returns, sO far as the amount of radiation is concerned. The three feet of rise in the pipes is only equal to one and one-half feet so far as its effect upon the circulation is concerned, since it is the average height of the pipes that must be taken into ac- count. We would prefer to carry the flow pipes upon the plates and the re- turns either on the walls or under the benches, but in order to secure a satis- factory circulation with uphill flows it may be necessary to run them about two feet below the ridge. The returns should be carried as high as possible, but even then it would be better to drop the boiler so that its top would not be more than two feet above the floor of the greenhouse. WHEN BOILEB IS EXTRA LARGE. We have built a greenhouse 12x56 and are putting in a Furman 6-section hot water boiler, rated at 1,650. The radiation for this house figures about 300 feet. We bought the extra large boiler so we could build a larger house later. We arc putting the boiler in a cellar eight feet deep; this will allow the returns to be about two feet above the top of the boiler. We have run a 2-inch flow pipe through the center of the house and connected it with nine ly^-iuch returns, four under one side bench and five under the other side bench. Later in the season we expect to put two 11/4-inch returns in a hotbed at the south sid
