more fertilizing sunshine; laying waste and building up, building up by laying waste, civilizing as well by war and avarice as by good-will and sweet charity, civilizing as surely, if not as rapidly, with the world of humanity struggling against it, as with the same human world laboring for it. Slowly rattles along the dim present, well-nigh buried in its own dust; it is only the past that is well-defined and clear to history. SUMMARY OF GEOGRAPHICAL KNOWLEDGE AND DISCOVERY FROM THE EARLIEST RECORDS TO THE YEAR 1540. Before entering upon the narration of events composing this history, it seems to me important, in order as well properly to appreciate the foregoing Introduction as to gain from succeeding chapters something more than gratified curiosity, that an exposition of Early Voyages should be given,—acting powerfully as they did on evolving thought and material development, giving breadth and vigor to intellect, enthusiasm to enterprise, and in elevating and stimulating that commercial spirit which was eventually to depose kings, exalt the people, strip from science its superstitions, from religion its cabalistic forms, and by its associations, its negotiations, its adventurous daring, its wars, its alliances, and its humanizing polities, to break the barriers of ancient enmity and bring together in common brotherhood all the nations of the earth. Therefore, I now propose to give a chronological statement of every authentic voyage of discovery made beyond the Mediterranean prior to 1540, while doubtful and disputed voyages will be discussed according to their relative importance. I shall notice, moreover, such books and charts relating to America as were produced during this period, with fac-similes of the more important maps, to illustrate, at different dates, the progress of discovery. It is my purpose, so far as possible, in the very limited space allowed, to state fairly the conclusions of the best writers on every important point. * * * * * One word as to the authorities consulted in the preparation of this Summary. Of books relating to America, published prior to 1540, there are in all about sixty-five; only twenty-five, however, contain original information; twenty-three are general cosmographical works with brief sections on America compiled from the original twenty-five; while seventeen merely mention the New World or its discoveries, and are therefore of no value in this connection. Of the forty-eight containing matter more or less important, there are over two hundred editions, the earliest of which only, in most instances, will be mentioned, and that without extensive bibliographical notes. These books and charts I notice in chronological order under dates of their successive appearance.
