With the departure of this interesting people from the cradle and home of their history, the chapter of their story which concerns us most is led to a natural end. Indeed it would be difficult to continue it, for such records of their wanderings as have been found are vague and incomplete; no two writers would interpret them alike. For these people mingled with others and lost their individual identity when they entered the broad path to Mexico over which such extensive migrations were then passing. The history of no one of the Nahuan nations is intelligible for its migratory period. Though the progressive line of architectural ruins stretching across the plains and down the valleys of New Mexico and Arizona into the Aztec empire, would seem to show the finger posts of the great marching route of these nations, yet so barren are the records of the so-called Cliff-Dwellers and other early inhabitants of our southwest territory, that many historians even doubt the connection between the architects of Casa Grande and of the palace of the Montezumas. To our minds the proofs which may be gathered from the preceding pages are sufficiently conclusive for our purpose. And it is not impossible that further researches among the records of these mediæval, these Dark Ages of aboriginal history, may set our conclusions beyond the reach of skepticism. If our little sketch be the means of suggesting to one reader how much there is of pleasure, of poetry, of truth, of religion, in Nature and natural associations,—if it be the means of prompting more thorough investigation and more careful preservation of every scrap of tradition now vanishing among the races of aboriginal America, we shall feel that it has not been written in vain.
