(4) An improved sort of ice-house, recommended by Bailey, gardener at Nuneham Park, Oxford, is shown in plan and section in Fig. 65, where the dotted line indicates the ground level. The well or receptacle for the ice _a_ is 10 ft. 6 in. wide at the base, and 3 ft. wider near the top; the walls are hollow, the outer portion being built of dry rough stone, and the inner wall and dome _f_ of brick. The outer wall _e_ might be replaced by a puddling of clay, carried up as the work proceeds. Over the top is a mound of clay and soil _g_, planted with shrubs to keep the surface cool in summer. The drain _i_ carries off the water formed by the melted ice, and is provided with a trap _h_ to prevent the ingress of air through the drain. There is a porch or lobby _b_ provided with outer and inner doors _c_; and apertures at _d_, to get rid of the condensed moisture, which, if not removed, would waste the ice. These ventilating doors should be opened every night, and closed again early in the morning. The most important conditions to be secured are dryness of the soil and enclosed atmosphere, compactness in the body of ice, which should be broken fine and closely rammed, and exclusion as far as possible of air. (_Gard. Mag. Bot._) (5) A very cheap way of storing ice has been described by Pearson of Kinlet. The ice-stack is made on sloping ground close to the pond whence the ice is derived. The ice is beaten small, well rammed, and gradually worked up into a cone or mound 15 ft. high, with a base of 27 ft., and protected by a compact covering of fern 3 ft. thick. A dry situation and sloping surface are essential with this plan, and a small ditch should surround the heap, to carry rapidly away any water that may come from melted ice or other sources. (_Gard. Jl._) (6) The following is an economical method of making small ice-houses indoors:--Dig a hole in a cool cellar, and make it of a size corresponding to the quantity of ice to be kept. At the bottom of this hole dig another of smaller diameter, the edge of which goes down with a gentle slope. This kind of small pit, the depth of which should be greater in proportion as the soil is less absorbent, must be filled with pebbles and sand. The whole circumference of the large hole is to be fitted up with planks, kept up along the sides with hoops, to prevent the earth from falling in. Then the bottom and all the circumference of this sort of reservoir must be lined with rye straw, placed upright with the ear downwards, and kept up along the planks by a sufficient number of wooden hoops. The ice is to be heaped up in this ice-house, which must be covered over with a great quantity of hay and packing cloth, on which should be placed a wooden cover and some light straw.
