The same remarks apply to the other sex, who from childhood to old age run the course in milder degree. Many of the maidens are pretty and the matrons are comely and wholesome to behold. The old, wrinkled and bowed go their way with quiet mien and busy themselves with the light duties in which their experience counts for much. In spite of the luxuriant hair that adorns the heads of this people, one may notice the difference of head shape which distinguishes them from the tribes of the plains. The cradle-board is partly responsible for this, since, from infancy, the children are bound to the cradle and obliged to lie on the back for longer or shorter intervals, and thus begins the flattening of the back of the skull. But the heads of the women are rarely flattened, probably because the girls are not so well cared for as the boys. There are among the Hopi a greater number of albinos in proportion to the population than may be found almost anywhere else. They go about their avocations like the rest and are in no way regarded as different from their kin. The impulse is to address them in English, and one feels surprised when they do not comprehend. One albino maiden of Mishongnovi has a marvelous growth of golden hair which shows to great advantage in her ample hair whorls. Many students believe that albinism has its origin in the nervous system, and perhaps the timidity of the Hopi explains the number of these remarkable people in their midst; but this is a theory, based on a theory. It has been observed that some of the albinos are below the average in intelligence, and it has been ascertained that the larger proportion of them are second in order of birth in a family. From the number of old people in the pueblos one would gain the impression that the Hopi are long-lived. All things considered, this is doubtless the truth, but there are no statistics to settle the matter; besides, the question of age is a doubtful one among the Hopi themselves. If "sans everything" is any criterion of a centenarian, there are such among the Peaceful People. One must conclude that, on passing childhood, the average Hopi is due for a second term of the helpless period. "Welcome" is not written over every Hopi door, but the spirit of hospitality pervades the entire population. This is one of the pleasant features of the Pueblos and is the chief reason why the Hopi are held in friendly remembrance by visitors. An acquaintance with the Indians in the different pueblos of the Southwest will convince one that there is a considerable range of disposition among them. Perhaps the extremes are the untractable Santo Domingans and the impressionable Hopi. It seems to be a matter of the elements of which the tribes have been made up and of their past experiences and associations.
