The educational value of color photography is brilliantly demonstrated in the reproduction of these polychrome costumes, when compared with the black-and-white photograph of the same subjects published on page 483 of the National Geographic Magazine for November, 1925.

Her bead collar of intricate pattern weighs two pounds, and no other girl in all Greenland has its exact duplicate, for she has wrought her own design, as do all her friends. Her bright red boots are decorated with mosaic panels of vari-colored leather.

Before the door of his sealskin tupik, this Eskimo surveys the waters of Smith Sound for signs of "whale-horses," which will supply him with food for the winter and a bone tip for his harpoon.

In northern Greenland, the Eskimos dwell in underground rock and sod igloos during the winter and in sealskin tents (seen above) in summer. It is only on the march in winter that they build snow and ice igloos for temporary shelter. Southward one finds the houses built more and more above ground, until at Sukkertoppen such "pebbledash" residences as this are encountered. The mother of the household, in the foreground, is skinning birds.
