The greatest difficulty to be met in the writing of an Indian play is the extensive misinformation about Indians. Any real aboriginal of my acquaintance resembles his prototype in the public mind about as much as he does the high-nosed, wooden sign of a tobacco store, the fact being that, among the fifty-eight linguistic groups of American aboriginals, customs, traits, and beliefs differ as greatly as among Slavs and Sicilians. Their very speech appears not to be derived from any common stock. All that they really have of likeness is an average condition of primitiveness: they have traveled just so far toward an understanding of the world they live in, and no farther. It is this general limitation of knowledge which makes, in spite of the multiplication of tribal customs, a common attitude of mind which alone affords a basis of interpretation.
