Any wrong impression, therefore, which the work conveyed was not due to the spirit of braggadocio pervading it, as asserted and commented upon by the English reviewers. No false statement was made intentionally; there were very few that were made mistakenly. But though Cooper purposed to tell nothing but truth about his country, he did not feel himself under obligation to tell all the truth. The attention was almost exclusively directed to that side of the national character which lent itself most readily to favorable treatment. What was unfavorable was either omitted altogether, or was very lightly passed over. One letter alone, and that not a long one, was devoted to slavery. It is plain that he was annoyed by it; to some extent, in spite of his confidence, disquieted by it, though the dangers he feared were not the dangers that actually came. Even at that early day there was enough to trouble the lover of his country in the criticism it encountered, for the glaring contrast between its professions of liberty and its practice; but far more in the dimly-seen shape of that gigantic struggle which, though itself vague and undefined, was already beginning to cast its lowering shadow over the future of the republic. So in a similar manner the literature, architecture, and art of America were passed over in a few pages, while letter after letter was given up to a description of its progress in wealth and comfort. Yet no one knew better than Cooper,--at a later period he took care his countrymen should not forget it,--that of all standards by which to test national glory, the material (p. 105) standard is in itself the lowest and most vulgar; and that the difference in real greatness between two places can never be measured by the comparative amount of sugar, or salt, or flour sold in each. Yet he remembered then, what later he seemed to forget, that the necessity of conquering the continent, of making it inhabitable for man, was at the time and must continue long to remain a very positive hindrance to the development of literary and artistic ability, because by the immense rewards it offered it attracted to the development of material resources the intellect and vigor of the entire land.
