All of the people in the district about Capes Vancouver and Romanzof, and thence to the Yukon mouth, are of unusually light complexion. Some of the women have a pale, slightly yellowish color, with pink cheeks, differing but little in complexion from that of a sallow woman of Caucasian blood. This light complexion is so exceptionally striking that wherever they travel these people are readily distinguished from other Eskimo, and before I visited their territory I had learned to know them by their complexion whenever they came to St. Michael. The people of the district just mentioned are all very short and squarely built. Inland from Cape Vancouver lies the flat marshy country about Big Lake, which is situated between the Kuskokwim and the Yukon. It is a well-populated district and its inhabitants differ from those near the coast at the capes referred to, in being taller, more slender, and having more squarely cut features. They also differ strikingly from any other Eskimo with whom I came in contact, except those on Kowak River, in having the bridge of the nose well developed and at times sufficiently prominent to suggest the aquiline nose of our southern Indian tribes. The Eskimo of the Diomede Islands in Bering Strait, as well as those of East Cape and Mechigme and Plover Bays on the Siberian coast, and of St. Lawrence Island are tall, strongly built people and are generally similar in their physical features. These are characterized by the unusual heaviness of the lower part of the face due to the very square and massive lower jaw, which, combined with broad, high cheek bones and flattened nose, produces a wide, flat face. These features are frequently accompanied with a low retreating forehead, producing a decidedly repulsive physiognomy. The bridge of the nose is so low and the cheek bones so heavy that a profile view will frequently show only the tip of the person's nose, the eyes and upper portion of the nose being completely hidden by the prominent outline of the cheek. Their eyes are less oblique than is common among the people living southward from the Yukon mouth. Among the people at the northwestern end of St. Lawrence Island there is a greater range of physiognomy than was noted at any other of the Asiatic localities. The Point Hope people on the American coast have heavy jaws and well-developed superciliary ridges. At Point Barrow the men are remarkable for the irregularity of their features, amounting to a positive degree of ugliness, which is increased and rendered specially prominent by the expression produced by the short, tightly drawn upper lip, the projecting lower lip, and the small beady eyes. The women and children of this place are in curious contrast, having rather pleasant features of the usual type.
