Since concrete is entering so largely into greenhouse construction, it is in- teresting to note that excellent perma- nent hotbeds are also being built of this material. The accompanying illus- tration shows hotbeds built by the George Wittbold Co., at its greenhouses at Edgebrook, 111., a suburb of Chicago. These hotbeds were built by the reg- ular greenhouse employees. A 1-2-5 mixture was used. The forms were made for the purpose, the entire job being poured at one time. The length was a mere matter of meeting the needs of the company; the other dimen- sions would be satisfactory anywhere. It was necessary to go far enough into the ground to get a secure footing, also to keep out frost. The inside of the form was made of second-hand lum- ber. The outside was corrugated iron, such as often is used on the roofs of boiler sheds. The width of the hot- bed was right for a standard sash. The back wall was thirty inches high, and the front wall twenty inches high, with a thickness of six inches. After the concrete had set the forms were knocked away and the heating material was put in. The hotbed is apparently due to last forever. The outside of the completed structure, shown in the illustration, shows the corrugations that were in the iron used in building the form. OBITUAEY. Joseph M. Cole. Joseph M.
