_Classification of the Revolutionary Writings._--The characteristic life of the period we now have in view was political, and not political only, but polemic, and fiercely polemic, and at last revolutionary; and its true literary expression is to be recognised in those writings, whether in prose or in verse, which gave utterance to that life. Such writings seem naturally to fall into nine principal classes. First, may here be named the correspondence of the time; especially, the letters touching on public affairs which passed between persons in different portions of America, and in which men of kindred opinions found one another out, informed one another, stimulated, guided, aided one another, in the common struggle. Indeed, the correspondence of our Revolution, both official and unofficial, constitutes a vast, a fascinating, and a significant branch of its literature. Undoubtedly, the best of all the letter-writers of the time was Franklin; and next to him, perhaps, were John Adams, and Abigail Adams, his wife. Indeed the letters of Mrs. Adams, mostly to her husband, and covering this entire period, are among the most delightful specimens of such work as done by any American. Not far behind these first three letter-writers, if indeed they were behind them, must be mentioned Jefferson and John Dickinson; and, for shrewdness of observation, for humour, for lightness of touch, for the gracious _negligée_ of cultivated speech, not far behind any of them was a letter-writer now almost unknown, Richard Peters of Philadelphia. Of course, no one goes to the letters of Washington, in the expectation of finding there sprightliness of thought, flexibility, or ease of movement; yet, in point of diligence and productiveness, he was one of the great letter-writers of that age. The second form of literature embodying the characteristic life of our Revolutionary era is made up of those writings which were put forth at nearly every critical stage of the long contest, either by the local legislatures, or by the General Congress, or by prominent men in public office, and which may now be described comprehensively as State Papers. It is probable that we have never yet sufficiently considered the extraordinary intellectual merits of this great group of writings, or the prodigious practical service which, by means of those merits, they rendered to the struggling cause of American self-government, particularly in procuring for the insurrectionary colonists, first, the respectful recognition, and then the moral confidence, of the civilised world.
