Boiler felt, properly split, has the advantage of cheapness, andis valuable. Where none of these materials can be obtained, twosheets of stiff paper, stretched on each side of a frame ^ of an inchdeep, and supported on a ledge of the same depth, may be fastenedinto the bottom of the box; and even bog peat, or a couple of thick-nesses of blanket, will serve a good purpose.
