Mr. Irving's work is one of great interest. The conquest of Florida by De Soto, while it is contrasted with the conquest of Mexico by Cortez, (which immediately preceded it) in regard to its results to those engaged in it, resembles it in the patient suffering and indomitable bravery of the adventurers, and in the numerous thrilling scenes through which they passed. While the conquest of Mexico enriched the followers of Cortez, and poured the wealth of the new world into the lap of Spain, that of Florida proved fatal to all who attempted it, and ended in disaster to the ultimate conquerors. Ponce de Leon, the visionary, who sought in Florida the Fountain of Youth, Vasques de Ayllon, the ruthless kidnapper, and Pamphilo de Narvaez, the well known rival and opponent of Cortez, had made fruitless attempts to colonize this disastrous coast. But the last and most splendid effort of that day, was made by Hernando de Soto, a cavalier who had served with Cortez, and had returned to Spain in the possession of immense wealth derived from the spoil of Mexico. The enjoyment of the highest favor at the court of his sovereign, the charms of a young and lovely bride, and the allurements of his splendid position at home, were insufficient to repress the spirit of adventure which he had imbibed in the wars in Mexico, and the prevalent belief that Florida presented a scene for conquest still more magnificent than Mexico. De Soto was doomed to prove that the golden dreams of wealth with which the unexplored regions of Florida had been invested, were baseless illusions. But his adventures and achievements afford a rich mine of romantic incidents which Mr. Irving has presented in a most attractive form: "Of all the enterprises," says he, "undertaken in this spirit of daring adventure, none has surpassed for hardihood and variety of incident, that of the renowned Hernando de Soto and his band of cavaliers. It was poetry put in action; it was the knight-errantry of the old world carried into the depths of the American wilderness: indeed, the personal adventures, the feats of individual prowess, the picturesque descriptions of steel-clad cavaliers, with lance and helm and prancing steed, glittering through the wildernesses of Florida, Georgia, Alabama, and the prairies of the Far West, would seem to us mere fictions of romance, did they not come to us recorded in matter-of-fact narratives of cotemporaries, and corroborated by minute and daily memoranda of eye witnesses."
