Although the prehistoric Indians of Tusayan have left no written records in the forms of books, documents, or codices, there survives from their time a most elaborate paleography which has been preserved on imperishable material in the dry soil of Arizona for several centuries. This paleography is a picture writing, often highly symbolic and complicated, but from it the student can obtain an idea of Hopi thought and its expression at that remote time. It reveals phases of ancient life which have been modified or lost in the subsequent development of the race.FROM THE BOOKS.
