[4] Alaska and Its Resources, p. 19: "Our attention was attracted by
the numerous graves. These are well worth the careful attention of
the ethnologist; many of them are very old. The usual fashion is to
place the body, doubled up, on its side, in a box of plank hewed out
of spruce logs and about 4 feet long; this is elevated several feet
above the ground on four posts, which project above the coffin or box.
The sides are often painted with red chalk, in figures of fur animals,
birds, and fishes."
