From Content: "Nothing in the progress of human knowledge is more remarkable than the recent discoveries in American arch?ology, whether we regard them as monuments of art or as contributions to science. The names of Stephens and Norman will ever stand pre?minent for their extraordinary revelations in Mexico and Yucatan; which, added to those previously made by Del Rio, Humboldt, Waldeck and D?Orbigny in these and other parts of our continent, have thrown a bright, yet almost bewildering light, on the former condition of the western world. Cities have been explored, replete with columns, bas-reliefs, tombs and temples; the works of a comparatively civilized people, who were surrounded by barbarous yet affiliated tribes. Of the builders we know little besides what we gather from their monuments, which remain to astonish the mind and stimulate research. They teach us the value of arch?ological facts in tracing the primitive condition and cognate relations of the several great branches of the human family; at the same time that they prove to us, with respect to the American race at least, that we have as yet only entered upon the threshold of investigation. In fact, ethnography and arch?ology should go hand in hand; and the principal object I have in view in giving publicity to the following too desultory remarks, is to impress on travellers and others who are favorably situated for making observations, the importance of preserving every relic, organic or artificial, that can throw any light on the past and present condition of our native tribes. Objects of this nature have been too often thrown aside as valueless; or kept as mere curiosities, until they were finally lost or become so defaced or broken as to be useless. To render such relics available to science and art, their history and characteristics should be recorded in the periodicals of the day; by which means we shall eventually possess an accumulated mass of facts that will be all-important to future generalization. I grant that this course has been ably pursued by many intelligent writers, and the American Journal of Science is a fruitful depository of such observations.4-* With every acknowledgment to these praiseworthy efforts, let us urge their active continuance. Time and the progress of civilization are daily effacing the vestiges of our aboriginal race; and whatever can be done to rescue these vestiges from oblivion, must be done quickly." ? --This text refers to the Kindle Edition edition.
