If the side walls have any glass, one additional return will be needed for each two feet of glass. For 50 degrees, use two flows and eight returns. TWO GREENHOUSES AND OFFICE. We intend to build two greenhouses, as indicated in the enclosed sketch, and should like to know how to pipe them for the best results. The temperature required will be 55 to 60 degrees in zero weather. House No. 1 contains no benches. House No. 2 has benches, as shown in the drawing. The houses are six and one-half feet high to the eaves and twelve feet high to the ridge. There are four feet of glass in the sides and glass in the gable ends. We also wish to know how to pipe the office. M. E. J. C—Ohio. The sketch which accompanies the letter shows two houses, 20x125 and 25x140, respectively, with one side and one end of each house exposed, and with the boiler room at one end of the longer house and the office at the op- posite end of the other house. For the larger house, I would use four 2%-inch flow pipes, placing one upon each plate and the others under the pur- lins, with thirteen 2-inch returns. Three returns should be under each of the benches and four on the outside wall. In the house 20x125, use the same number of flow pipes, extending one into the office to supply the radiation needed there, but since the sketch does not show bow muc
