MSS BhlaUls At*.. CHXCAGO MentloD Tbe Review when you write. after April 1 the temperature is seldom below 35 degrees. Will the foregoing plan give the proper temperature for the crops mentioned? If I should connect the piping with the greenhouse boiler, will a cut-off valve be required at the head of each frame or only on the flow and return in the boiler roomf Can you give the heating capacity of the boiler? It is a round boiler, four feet high above the ash-pit and twenty-two inches in diam- eter. The fire-pot is twenty-seven inches high and eighteen inches in diameter. There is a 2-inch water leg around the fire-pot. The boiler has two 2-inch flows and two 2-ineh returns. C M. C. The plan proposed for heating cold- frames by means of hot water pipes is a good one and there should be no diffi- culty in keeping up the desired tem- perature in the frames. It will be necessary, of course, to have the boiler two or three feet below the level of the return pipes. A heater of the size de- scribed should be large enough to sup- ply 275 to 300 square feet of radiation. It will be best to have a valve upon each pipe where it enters the hotbeds. HEAT FOR TOMATO BEDS. I intend to grow plants for a catsup factory here and I shall build thirteen beds, 5%xl33 feet. I shall heat with steam, using a tubular boiler. As I am not familiar with steam heating, I should like to get some advice on the matter. I have plenty of 2-inch pipe on hand. My idea is to run a 2-inch pipe through the center of each bed, putting a stop-cock at the farther end and not returning the steam to the boiler, but letting it blow out of each valve. Now, a little advice on connecting the boiler wou
