The invention of alphabetic writing being by general admission the great step marking the change from barbarism into civilization, the history of its earlier development must be valuable. It is inferred from internal evidence that picture-writing preceded and originated the graphic systems of Egypt, Nineveh, and China, but in North America its use is still modern and current. It can be studied there, without any requirement of inference or hypothesis, in actual existence as applied to records and communications. Furthermore, its transition into signs of sound is apparent in the Aztec and the Maya characters, in which stage it was only arrested by foreign conquest. The earliest lessons of the birth and growth of culture in this most important branch of investigation can therefore be best learned from the Western Hemisphere. In this connection it may be noticed that picture-writing is found in sustained vigor on the same continent where sign-language has prevailed or continued in active operation to an extent unknown in other parts of the world. These modes of expression, _i. e._, transient and permanent idea-writing, are so correlated in their origin and development that neither can be studied with advantage to the exclusion of the other. The limits assigned to this paper allow only of its comprehending the Indians north of Mexico, except as the pictographs of other peoples are introduced for comparison. Among these no discovery has yet been made of any of the several devices, such as the rebus, or the initial, adopted elsewhere, by which the element of sound apart from significance has been introduced. The first stage of picture-writing as recognized among the Egyptians was the representation of a material object in such style or connection as determined it not to be a mere portraiture of that object, but figurative of some other object or person. This stage is abundantly exhibited among the Indians. Indeed, their personal and tribal names thus objectively represented constitute the largest part of their picture-writing so far thoroughly understood.
