In spite of the immense burden of great undertakings which he carried, Mr. Hill repeated the substance of this address on many occasions. Lord Rosebery once said that speeches were the most ephemeral of all ephemeral things, and for some time it looked as if one of the most important speeches ever delivered by a public man on a great public issue was going to illustrate the truth of this saying. It seems strange that his facts and arguments should have remained unchallenged, and yet unsupported, by other public men. Perhaps the best explanation is to be found in a recent dictum of Mr. James Bryce. Speaking at the University of California, the British Ambassador said: "We can all think of the present, and are only too apt to think chiefly about the present. The average man, be he educated or uneducated, seldom thinks of anything else." There are, however, special circumstances in the history of the United States which account for the extraordinary unconcern about what is going to happen to the race in a period which may seem long to those whose personal interest fixes a limit to their gaze, but which is indeed short in the life of a nation. After the religious, political, and military struggles through which the American nation was brought to birth, there followed a century of no less strenuous wrestling with the forces of nature. That century stands divided by the greatest civil conflict in the world's history; but this only served to strengthen in a united people those indomitable qualities to which the nation owes its leadership in the advancement of civilisation. The abundance (until now considered as virtual inexhaustibility) of natural resources, the call for capital and men for their development, the rich reward of conquest in the field of industry, may explain, but can hardly excuse, a National attitude which seems to go against the strongest human instinct--one not altogether wanting in lower animal life--that of the preservation of the race. It is an attitude which recalls the question said to have been asked by an Irishman: "What has posterity done for me?" But this was before Conservation was in the air.
