The sides of the ship were lined with tarred felt, then came a space with cork padding, next a deal panelling, then a thick layer of felt, next air-tight linoleum, and last of all an inner panelling. The ceiling of the saloon and cabins consisted of many different layers: air, felt, deal panelling, reindeer-hair stuffing, deal panelling, linoleum, air and deal panelling, which, with the 4-inch deck planks, gave a total thickness of about 15 inches………….The skylight which was most exposed to the cold was protected by three panes of glass, one within the other, and in various other ways….”

“Whether the thermometer stands at 22° above zero or at 22° below it, we have no fire in the stove.
