The annals of Mexico fare no better before the fire of criticism. It is extremely doubtful that their earliest reminiscences refer to any event outside the narrow valley parcelled out between the petty states of Tenochtitlan, Tezcuco, and Tlacopan.[6] The only fact that bears out the long and mysterious journey from the land of the Seven Caves, Chicomoztoc, in the distant northwest, by the great water, is that the learned and indefatigable Buschmann has conclusively shown that the four languages of Sonora and all the dialects of the Shoshonian family reveal marks of continued and deep impressions of the Nahuatl tongue.[7] But the chronicles of Mexico proper contain no fixed date prior to that of the founding of the city of Tenochtitlan, in the year 1325 of our era. I am aware that there are still some writers who maintain that both the Mexican and the Maya astronomic cycles assume a commencement for their records centuries, even thousands of years, before the beginning of our era. These opinions, however, have not obtained the assent of other students. We are too ignorant both of the astronomy and the methods of writing of these nations to admit such claims; and the facts advanced are capable of quite other interpretation. It is, on the whole, rare for the American tribes to declare themselves autochthonous. The Mayas, on the peninsula of Yucatan, stated that their earliest ancestors came there from beyond the seas, some from the far east, others from the west. So the Toltecs, under Quetzalcoatl, were fabled to have entered Mexico from beyond the Eastern Ocean. The Creeks and Choctaws pointed to the west, the Algonkins generally to the east, as their primal home.[8] These legends are chiefly mythical, not much truer than those of other tribes who claimed to have climbed up from some under-world. Sifting them all, we shall find in them little to enlighten us as to the pre-historic chronology of the tribes, though they may furnish interesting vistas in comparative mythology. That in which we may expect the legends of tribes to be of most avail is their later history, the record of their wars, migrations and social development within a few generations. The spirit of the uncivilized man is, however, very careless of the past. We have means of testing the exactness of such traditions in some instances, and the result is rarely such as to inspire confidence in verbal records. Those of you who were present at the last meeting will remember how diversely two able students of Iroquois tradition estimated its value. Even when remarkable events are not forgotten, the dates of their occurrence are generally vague. The inference, therefore, is that very few data, dependent on legendary evidence alone, can be accepted.
