Sometimes valves are placed at each end of several of the individual pipes ia the coils, but where there are so many coils this is not really neces- sary, although it is often desirable to be able to shut off the steam from one pipe in each coil.

Sometimes valves are placed at each end of several of the individual pipes ia the coils, but where there are so many coils this is not really neces- sary, although it is often desirable to be able to shut off the steam from one pipe in each coil. There should be a check valve in the main return near the heater and, if a single flow is used for each house, it is often convenient to be able to cut off the entire house with one valve located near to where it leaves the main flow pipe. Of course, all the pipes in the system should run downhill, when this is possible. HEATING PARTITIONED HOUSE. Kindly inform me how to heat a greenhouse, 32x180 feet, with side walls five feet six inches high and eight feet high at the ridge. There are three feet of glass in the east side, four feet of glass in the west side, while the ends have three feet of woodwork and the remainder glass. A glass partition in the center of the house divides it. I wish to maintain 55 degrees in the south end, which is the lower end, and 75 degrees in the north end. I have six raised benches in the north end, but the beds in the south end are solid. I wish to heat with steam, using a 10- horsepower vertical steam boiler, which wUl be placed in the north end of the house. I am using oil for fuel. The temperature goes to 32 degrees above zero hero. E. E. H.—Cal. It is noted that a 10-horsepower steam boiler is to be used for heating. It would be preferable to use a 15-horse- power boiler, although with oil as fuel it will, doubtless, be possible to pro- vide the steam needed for the house. The fact that one end of the house is to be kept 20 degrees warmer than the other complicates matters to some extent, but we are confident that the following arrangement of the piping will give the results desired: Run a IV^-inch lead on eac
