 wide, covers the upper space between the one-inch strips, 

 thus making a dead-air space between the two boxes. 

 The construction of the cover is the same as that of the 

 bottom, with the exception that there is a flange at the 

 front and sides of the cover. The sides, bottom and 

 cover of the refrigerator are built of three-quarter-inch 

 tongued and grooved lumber, five and a half inches 

 wide. The ends are constructed of one and one-eighth 

 inch tongued and grooved flooring three and a half 

 inches wide. The inside of the ice box is lined with 

 galvanized iron.
