I should have explained before that the ice does not rest directly on the joists; but there is a bed of oak lath, about 1 1/2 by 3 inches, laid across the joists, about 4 or 5 inches apart, on which the ice is laid. I would further suggest that another cold chamber can as well be had by making a cellar under the one shown, with a lattice floor between them. It would be necessary to finish the sides and bottom of this cellar in the most complete manner, as above described. At the entrance to the store-room there must be a vestibule, either inside or outside, as space or circumstances may direct. If outside the walls should be thick and the door very heavy. The doors, both inside and outside, should be fitted with rubber, so as to close perfectly tight, and both doors must never be opened at the same time. This vestibule should be large enough to contain a fair wagon load of goods, so that if you are receiving a load of stuff you are not required to stop until all is in the vestibule and ready to store. This house only needs filling once a year. The temperature will range from 34 deg. in winter to 36 deg. in summer, and will preserve fruit perfectly from season to season. The opening for putting in the ice, shown just under the pulley in the cut, has two doors with a space between; each door a foot thick. The window in the cold room has three sets of sash, well packed or cemented. The walls are 13 inches thick, lined with 17 inches of sawdust. Thirty-six inches of sawdust are put on the floor over the ice. The building shown is 25 feet square, inside measure, and 22 feet from floor of cold room to ceiling over the ice. The ice-room is 12 feet high, and the cold room 9 feet. Pillars are required under the center of the ice.—Country Gentleman.
Cheap Ice-Houses.
Settlers in the newer portions of the country are often deprived of many comforts which are easily accessible in long-settled places. Whatever contributes to lessen these privations, if at little cost, should merit special attention. A cheap ice-house may be made to afford an important share of country comforts in such settlements. There is nothing to prevent an abundant supply through the heat of summer where there is a stream or sheet of water within two or three miles from which clear blocks of ice may be sawed. Sawdust is the best material for packing, but in its absence chaff, chopped straw, or even straw unchopped may be made to answer the purpose.
Fig. 1.
A costly and elaborate building is no better than the cheapest structure for keeping ice, if care is only taken to have it properly packed, which is very easily done after one “knows how.” We have never seen ice better preserved through a long and hot summer than in a board shanty with only one thickness of siding, and that full of cracks and crevices. For a new settlement one built of logs, like that shown in the accompanying figure (Fig. 1), may be made to answer a good purpose. The floor may be slabs, and the roof a covering of brush to hold the packing to its place, if a slab roof is not readily made. If sawdust is used for packing, the crevices between the logs will need close stopping; or, still better, it can be faced on the inside with slabs set upright, with the smooth side inward. If straw is employed, the rough logs may remain, and the crevices between them may be left open. For sawdust a well-packed space of 10 inches between walls and ice will keep the ice well; chopped straw should be 15 or 20 inches thick, and long straw should occupy a space of 2 feet. Stiff, coarse straw will not answer unless packed very solid; finer and softer, as of thickly sown oats, is better, and the walls which it forms need not be quite so thick. Fine hay would be still better, and would answer if only a foot and a half thick and well put in. Dry swamp moss, such as nurserymen use for packing trees and plants, would be one of the very best substances for protecting the ice, if only a foot thick.

Having prepared the house and packing cut the blocks of ice of precisely equal size, using a cross-cut saw with one handle removed, to go under water. The size should be measured and scratched on the surface for the saw to follow. Two feet square is a convenient size. When cut lift them out with a light plank having a batten nailed across one end to hold them (Fig. 2). Place about 10 inches of sawdust on the floor (or twice as much solid straw), and build the structures solid with the ice blocks, ramming in the sawdust or other packing as the structure goes up (Fig. 3). When finished cover it with a thickness of packing nearly equal to that at the sides. It is important that there be free ventilation over the top, which the loose brush will not prevent. If there is a slab roof the air must blow freely between this roof and the top covering. The slab floor will allow a free drainage of all the water which runs down through the packing from the melting ice.
