. The American carnation; How to grow it. Ward, Charles Willis. Soils crosses and a two-inch tec, connecting these with nipples forming a header which shall be about four inches shorter than the width of the bench in which the soil is to be sterilized; screw the one-inch pipes into this header firmly, leaving them so that the openings of the drill holes will stand at the sides of the pipe and not up and down. The object of this is to force the steam later- ally through the soil, and not upward. If the hole stands upward the pressure of steam will drive an opening straight through the soil to the sur- face, and the steam will escape through this aperture without penetrating the soil. The accompanying drawings will show better how the header is made than can be conveyed by a description. When this apparatus is completed and. Header placed in the bench, it should be connected with the steam main by a two- inch pipe. A right and left coupling, or a union, may be used to connect with the steam pipes. When finished, this will make an apparatus that will sterilize the soil in thirty to forty feet of bench, according to the lengths of one-inch pipe used. Place the apparatus in the bottom of the bench, and fill the remainder of the bench with soil, so that the entire machine is fully covered to a depth of six to seven inches, extending ten to twelve inches be- yond the ends of the pipes. Now cover the surface of this soil with old gunny sacks, or pieces of burlap, horse blankets, or any old cloth that may be at hand. A pressure of fifty pounds of steam should be carried upon the boiler at the time of injecting the steam into the soil. Open the valves gradually, and allow the steam to run into the sterilizing machine, lightly at first, increas- ing the pressure so that the entire force of steam will be turned into the soil within one minute from the time the valve is opened. Let this steam blow into the soil for twenty to thirty minutes, after which time it may be turned off
