These drying-floors may be built of brick with the long sides as long as required, while the short sides should be about twelve feet long. The back wall is six feet high, while the front wall is only six inches high, which, with the above length of side wall, would give enough slope. In Malaga the interior is filled with black gravel and tamped hard, but for our purpose probably nothing would be superior to asphaltum, bituminous rock or cement. It must first be ascertained if bituminous rock would not impart a flavor to the grapes, in which case cement would be the most useful flooring. In order to allow the rain to run off, the front wall should be pierced with small holes close to the ground, but this would only be necessary in case the bed is filled with gravel, or no cement floor exists on top of it. Along the back part of the floor should be set a row of uprights of two by four lumber, driven securely in the ground. On the top of each post is set an eyelet, through which runs a stout wire along the whole back of the frame. A canvas cover long enough to reach the whole length of the floor should be used for covering, and, in order to secure it to the wire and the posts, it should be hemmed and furnished with small rings to run on the wire. In front similar rings are set in order that the canvas may be secured to the smaller posts and kept down in case of wind. On such floors common trays may be used. To make the canvas impervious to rain, it may be painted with boiled linseed oil. The above are only suggestions based on the Spanish drying-floors. For a full description of them, I beg to refer to the article on Malaga. In using linseed oil, care should be taken that only pure oil is used. There is linseed oil which contains chemicals which rapidly rot the canvas.
