Moreover his career was strictly selfish and personal; he led no party, represented no idea, and left no permanent trace. There was also William H. Crawford, who narrowly missed being President, and who was a greater man than many of the Presidents; but he _did_ miss, and he died, and there was an end of him. There was Buchanan also; intellectually he had the making of a statesman; but his wrong-headed blundering is sufficiently depicted for the purposes of this series by the lives of those who foiled him. These names, again, are mentioned only as indications of the scheme, as explaining some exclusions. There are other exclusions, which have been made, not because the individuals were not men of note, but because it seemed that the story of their lives would fill no hiatus among the volumes of the completed series. The editor cannot expect every one to agree with him in the selection which he has made. We all have our favorites in past history as well as in modern politics, and few lists would precisely duplicate each other. So the only thing which would seriously afflict the editor with a sense of having made a bad blunder would be, if some one should detect a really gaping chasm, a neglect to treat somewhere among the lives some important item of our national history falling within the period which the series is designed to cover. The whole series naturally shapes itself, in a somewhat crude and rough way to be sure, yet by virtue of substantial lines of division, into a few sub-series or groups. The first of these belongs to the Revolutionary period, what may be called the destructive period, since it witnessed the destruction of the long-established political conditions. In this group we find the leaders of the disaffection and revolt: Benjamin Franklin, Samuel Adams, Patrick Henry, and George Washington. Washington, of course, might properly find a place also in the second group; but for the purposes of separation he is by preference placed in the first one, because the Revolution was to so great an extent his own personal achievement, his transcendent and crowning glory. The second group, constituting the constructive period, comprises the men who were foremost in framing the Constitution, and in organizing and giving coherence and life to the new government and to the nationality thereby created. This is introduced by John Adams. He, like Washington, might properly find a place in both the first and the second groups, but the distinction of the presidential office brings him with sufficient propriety into the second. The others in this group are Alexander Hamilton, Gouverneur Morris, John Jay, and John Marshall.
