The doors swing inward, and are large enough to admit a single horsecart. The sides and rear end are lined with inch boards. The side walls are four feet high in the clear. To form the roof, boards are cut of a length which will raise the center seven feet above the floor and give easy passage for a horse. Midway between the center and either wall a 2 × 4 post is set upon a footing of brick, and above it under the roof boards a 1 × 4 strip is run the length of the cellar. On top of the first roof boards a layer of straw is placed, which will be a foot in thickness when pressed down. On top of this straw a second set of roof boards is placed, covered with another layer of straw; on top is now placed a tight cover of matched boards, and two thicknesses of tarred paper over the whole. Battens are placed over the joints in the matched boards to hold down the tarred paper and prevent any water passing through. The outer edges of the roof are set firmly against the ground at the top of the walls. On the upper hillside tiling should be placed, or other draining to carry off the surface water. A porous, gravelly side should be selected whenever available. In the front two windows are placed and one large one at the rear, double sashes being fitted during the coldest weather. [Illustration: FIG. 90. CROSS SECTION OF FRUIT CELLAR.] THE CHEAPNESS AND CAPACITY OF SUCH A CELLAR.--For a cellar one hundred feet deep the estimated cost is $100, no skilled labor being required. Rough lumber is used except for the last roof boards. Large storage room is provided in such a cellar, fifty thousand celery plants have been accommodated in one; hundreds of bushels of vegetables, apples and other fruits have been held in it during the fall and winter. A COLD PACKING HOUSE.--On large fruit farms a building designed to properly care for the fruit during shipping and packing, and as a store house for temporary use, is desirable. The illustrations below (Figs. 91 and 92) are taken from a ventilated fruit house with insulated walls, which has operated very successfully in Ontario County, N. Y. A perspective view is shown in Fig. 91. The main building is 24 × 36 feet, built into a slight hill. The basement is built with stone walls eighteen inches thick, extending two feet below the surface and rising six feet above it. The floor is made of eight inches of clean coarse gravel, with a coat of hydraulic cement grouted in a finishing coat on top, thus making a dry, hard floor. [Illustration: FIG. 91. PERSPECTIVE VIEW OF FRUIT HOUSE.] The basement is divided into convenient apartments. The entrance is from the front and north sides, the floor being almost level with the outside surface. Both the doors and windows are double, the latter being provided with screens to keep out insects when open for ventilation. This basement is ceiled with inch boards, on top of which, between the joists, is placed an inch and one-half of mortar.
