It is no part of the task which has been undertaken in these pages to sketch the mutations of political parties, or to trace the historical order and significance of events, save in their immediate and indispensable connection with our appropriate subject. So closely identified, however, has been the public life of Mr. Davis with the question of States' Rights, so ardent has been his profession of that faith, and so able and zealous was he in its advocacy and practice, that his life virtually becomes an epitome of the most important incidents in the development of this great historical question. His earliest appearance upon the arena of politics was at a period when the various issues which were submitted to the arbitrament of arms in the late war began to assume a practical shape of most portentous aspect. The address which first challenged public attention, and that extensive interest which has rarely been withdrawn since, was an emphatic indorsement of the political philosophy of Mr. Calhoun and a glowing panegyric upon the character and principles of that immortal statesman and expounder. Unreservedly committing himself, then, he has steadfastly held to the States' Rights creed, as the basis of his political faith and the guide of his public conduct. If it be true that the decision of the sword only establishes facts, and does not determine questions of principle, then the principle of States' Rights will be commemorated as something more valuable, than as the mere pretext upon which a few agitators inaugurated an unjustifiable revolt for the overthrow of the Government of the Union. Nothing is more likely than that many who recently rejoiced at its suppression by physical force, may mourn its departure as of that one vital inspiration, which alone could have averted the decay of the public liberties. Practically a "dead letter" now in the partizan slang of the demagogues who rule the hour, since its prostration by military power in the service of the antipodal principle of consolidation, it will live forever as the motive and occasion of a struggle, unparalleled in its heroism and sacrifices in behalf of constitutional liberty.
