Dr. Hamilton, one of the most entertaining of American travellers, appears to advantage even beside the urbanity of Byrd and the sprightliness of Mrs. Knight. Bent upon no special errand, he observed freely, and all the more so, one suspects, because of his detachment. Such a quality was not so easy during the next generation, when the wars between the French and English in America, the beginnings of colonial, and then national, pride, the growth of natural science, and the coming of the romantic spirit of solitude and love of nature furnished new motives. Then travelling became a fad, a profession, a duty, and led to the production of an extensive literature which may more properly be discussed with the work of men who were no longer colonials but citizens of the new republic.
