the explanatory and apologetical notes are duly inserted in new editions of geological works, and nothing more can come of the mistake. But it is difficult to foresee when the British public will believe that the Americans are a mirthful nation, or even that the French are not almost all cooks or dancing-masters. A century hence, probably, the Americans will continue to believe that all the English make a regular study of the art of conversation; and the lower orders of French will be still telling their children that half the people in England hang or drown themselves every November. As long as travellers generalize on morals and manners as hastily as they do, it will probably be impossible to establish a general conviction that no civilized nation is ascertainably better or worse than any other on this side barbarism, the whole field of morals being taken into the view. As long as travellers continue to neglect the safe means of generalization which are within the reach of all, and build theories upon the manifestations of individual minds, there is little hope of inspiring men with that spirit of impartiality, mutual deference, and love, which are the best enlighteners of the eyes and rectifiers of the understanding. Above all things, the traveller must not despair of good results from his observations. Because he cannot establish true conclusions by imperfect means, he is not to desist from doing anything at all. Because he cannot safely generalize in one way, it does not follow that there is no other way. There are methods of safe generalization of which I shall speak by-and-by. But, if there were not such within his reach, if his only materials were the discourse, the opinions, the feelings, the way of life, the looks, dress, and manners of individuals, he might still afford important contributions to science by his observations on as wide a variety of these as he can bring within his mental grasp. The experience of a large number of observers would in time yield materials from which a cautious philosopher might draw conclusions. It is a safe rule, in morals as in physics, that no fact is without its use. Every observer and recorder is fulfilling a function; and no one observer or recorder ought to feel discouragement, as long as he desires to be useful rather than shining; to be the servant rather than the lord of science, and a friend to the home-stayers rather than their dictator.
