For each two and one-half feet of glass in the walls we would add another re- turn. We would prefer to use 1^4-inch pipe for the returns, and would sub- stitute fourteen pipes of that size for the , ten 2-inch. In the carnation houses, if they are twenty-five feet in width, we would use one 2 ^^-inch overhead flow pipe and seven 2-inch or ten 1^4-inch re- turns. We would place a portion of the re- turns under the benches, but just how many should be used in that way will de- pend upon the number and width of the benches. As a rule we would place about one-third of the returns under the benches in houses from twenty-five to thirty feet in width. Thus, in the rose house we would use about four of the 2-inch pipes under the benches or from six to eight of the 1^-inch re- turns, depending upon the number of the benches and whether there is glass in the side walls. We would place the flow about two feet below the ridge. The size of the main will be deter- mined in part by the distance from the boiler to the greenhouses and by the thoroughness with which it is insulated. If the houses are practically of the size mentioned above, we would use a 4-inch main, with a 3-inch pipe for the con- densed steam, covering both carefully to hold the heat. Particularly when ex- haust steam is used, it is desirable to be able to return the water by gravity. If this cannot be secured, a steam pump or trap should be used. NEWPORT, R. I. An exhibit of polyanthus by William MacKay, gardener for H. A. C. Taylor, was awarded a gratuity at the regular meeting of the Newport Horticultural Society in Music hall last week, and a gratuity and cultural certificate were given to Charles Philpott for an exhibit of Princess
