. Annual report of the New York State College of Agriculture at Cornell University and the Agricultural Experiment Station. New York State College of Agriculture; Cornell University. Agricultural Experiment Station; Agriculture -- New York (State). Hotbed Construction and Management 1619 and where the bed is to be used for any length of time, this depth will be found very satisfactory. Nevertheless, the depth of bed is but a slight factor in hotbed construction and may be changed at will by the operator, who can either make the pit shallower or fill with other material than manure on the lower level (page 1626). The depth of the pit will be regulated by local conditions. New stakes are driven 6 inches south of the first stakes placed on the east and west ends, and these should be set far enough from the edge of the excavation to be firm. These stakes are connected by a line, drawn tight. This line then represents, in the case of an all-wood pit, the front. Fig. 12.—Cross-section of hotbed or south side of a row of posts or 2X4-inch scantlings that are to serve as the support of the back boarding. These posts or scantlings should be sunk in the soil at least 1 foot, and preferably 18 inches, below the bottom of the bed. They should extend 42 inches above the bottom of the bed, each one being set plumb with the line. The distance from the middle of one post to that of the next is 4 feet except in case only one or two beds are installed, when a distance of 3 feet is better. When all the posts are set, 2x6-inch planking is nailed with twenty-penny nails along their tops, 42 inches being provided for from the bottom of the pit to the top of the planking. By the use of a carpenter's level the top of the planking can be made in one plane, or level. The planking can.
