336 CORK INSULATION of the surrounding atmosphere followed upon the use of thick ; masonry walls underground and of walls of heavy timbers ' or planks in structures above ground. Following the same i development, and true to tradition,* the ice chest in time became an ice-box, smaller in length, made of oak, chestnut ' or other hard wood, with hollow walls lined inside with sheet [ zinc, standing upon raised feet formed from prolongations of the side posts, a hole in the bottom for the water to drain FIG. 156.—SLIDING-TOP HOUSEHOLD ICE CHEST. away, with perhaps a shallow pan underneath to catch the drip. The very first of these ice-boxes had wood pieces laid in the bottom to keep the ice and food from contacting with the metal lining, but there was no provision for the separa- tion of the food from the ice. The lid, usually of double layer boards with no air space between, was at first hinged, and; later, in some instances, built in two sections and made to slide. As time passed, these convenient household ice-boxes were provided with a vertical division across the box at the *The box, whatever its shape or purpose or the materials of which it is fashioned, is the direct descendent of the chest, one of the most ancient articles of domestic furnishings.

In due course, it became the practice in cold stores to con- struct double walls and fill the intervening space with flaked charcoal, silicate cotton, small pumice, sawdust, and similar loose or granular materials; and the principle of the over- FIG.

This influence was quickly reflected in the large beer and meat coolers of retail establishments and in turn in the household ice-box, flaked charcoal becoming the preferred type of loose fill <strong>insulation</strong> between ice-box walls, followed later by silicate cotton, or mineral wool. Then for the first time the household ice-box was elevated, so to speak.
