O, Fig. 1, is a movable air-tight cover, made In constructing a house embodying my into iit snugly to the sides of the ice-reservoir, vention, the surface of the ground should rst so as to insulate its lower portion, containing be leveled and coated with some substance imthe ice, from its upper portion, which, after pervious to moisture, such as pitch, asphaltum, placing the ice-cover O, is packed with some or bituminous substances are used, they should the two compartments of the ice-reservoir may be covered with sheet metal, cement, or other be made more complete by the application of inodorous substance. On this bed there is' tarred canvas or other luting to the edge of spread and closely packed a layerof chad of the cover O. This cover may be raised .andsome three on four feet thick, over which is lowered by means of the rope K' lpassing over grooved, or of sheet `metal or cemented tiles, Fans K, Figs. 1 and 2,- may be used to stir the or any other suitable material.

The best material for window closed by a thielgnon-conductin g shut. this door, I think, is galvanized sheet-iron. It ter. ought to be made tight by riveting and solder- The description above given is more partieularly-spplceble to houses or rooms for preserving fruit and other articles `requiring' the I greatest cold sind dryness and mostperfe'ct in snlation. For other coarser purposes, such as preserving beer and the like, less cure is re quired. The walls and foundation ma-y be made less perfect and the absorbcnts dispensed with altogether. The metallic ioor ought still, in my judgment, to be tight; but .this is not indispensable. The leaks-ge muy be carried o i by troughs or other means, and the ordinary dmpness, which would be fata-1 to fruit, ishere lessl prejudicial.

The main feature of my invention consists, then, as will readily be seen, in the nir-tight casings of walls and in the use of a. metallic `11001', through which the cold of the ice is sent down into the chamber below. Foral! nicer purposes this oor should rest on metal, and

should be as nearly tight as possible; but for many; other purposes it will answer nearly,

desir( described.
