The mode of recording thought, among these tribes, by means of pictorial signs, and mnemonic symbols, has attracted particular attention, and gives the author hopes, that he has been enabled to collect, and bring forward, a body of facts, in this department, which will recommend themselves by their interest and novelty. Confidence, inspired by long residence in their territories, revealed to him another trait of character, in the existence among them of a traditionary imaginative lore, which is repeated from father to son, and has no small influence upon their social condition. It is in these two departments, that, he believes, he has opened new and important means of judging of the Indian character, and discovered the sources of views and opinions, on many subjects, which had escaped previous inquirers. There is one more point, to-which he will here invite a momentary attention, and which, although not usually enumerated as among the practical causes that influenced Indian society and character, is yet believed to exercise a strong, though silent sway, both upon the question of the mental character, and its true development. The author alludes to the topic of their languages. Some of the most venerated writers present a theory of the origin of national government languages and institutions, difficult or impossible to be conformed with the nature of man in society, and unsupported by such evidence as their doctrines require. Such, he regards, the theory of the "social compact," except it be viewed in the most undefined and general sense possible. Such, also, is the theory of the origin and improvement of languages. The system of government generally prevailing among the Indian tribes, is indeed so simple and natural, under their circumstances, that it is thought no person would long seek for the traces of any great legislator, giving them laws in any past period. When, however, we consider the curious structure of their languages, we find an ingenuity and complexity, far surpassing any theory to be discovered in that of the modern languages of Europe, with, perhaps, some exceptions in the Basque and Majyer, and even beyond any thing existing in the Greek. As the latter has long been held up as a model, and the excellencies of its plan attributed to some unknown, but great and sagacious, learned and refined mind, we might feel justified in assigning the richness of forms, the exceeding flexibility, and the characteristic beauties and excellencies of the Indian tongues, to a mind of far superior wisdom, ingenuity, and experience. Yet how perfectly gratuitous would this be! All history bears testimony against the human invention and designed alteration of language; and none but a mere theorist can ever embrace the idea that it is, or ever was, in the power of any man, to fabricate and introduce a new language, or to effect a fundamental change in the groundwork of an existing one. This, at least, is the decided opinion of
