It has theadvantage that its position can be changed from season toseason, and it can be taken down and placed under coverduring the part of the year that it is not in use. Grout, stone, or brick are sometimes used for making thehot-bed frame, when it is located in a permanent position. HOT-BEDS 65 These materials are lasting, substantial, and are well recom-mended by those who have had experience with them. The size of the frame depends upon the number of sashthat are to be used. For a four-sash hot-bed, the size of .theframe will be G x 12 feet. If another sash is added, the lengthof the frame will be extended o feet, the latter distancebeing the width of the Fig. 43.—A four-sash hot-bed frame supported at each corner by two byfours driven into the ground. The frame extends east and west and is setto slope toward the south. The pit is 2 feet deep, 6 feet wide and 12 feetlong. The shape of the frame is shown in Fig. 43, in which itwill be noticed that one side is narrower than the difference is 6 inches, which provides a slope of 1inch to the foot when the sash are in place. This slopepermits the suns rays to enter at a less oblique angle, andallows water to pass away freely. The corners of the framemay be fastened with angle iron and bolts, as shown inFig. 44. This method of fastening is substantial and givesopportunity to take the frame down and put it away in smallspace when not in 66 CONSTRUCTION OF FORCING STRUCTURES The Pit.—The pit varies in depth from 18 to 30 inches,and has the same length and width as the frame. Thedepth of the pit depends upon the season when the bed isstarted. If it is to
