Equally extensive and important were his views on the subject of a peace establishment, for which he saw the necessity of providing, as the time approached when the Confederation would necessarily be tested as a government for the purposes of peace. To adapt a constitution, whose principal powers were originally designed to be exercised in a state of war, to a state of peace, for which it possessed but few powers, and those not clearly defined, was a problem in the science of government of a novel character. It might prove to be an impossible task; for on applying the constitutional provisions to the real wants and necessities of the country, it might turn out that the Confederation was in some respects destitute of the capacity to provide for them; and in undertaking to carry out its actual and sufficient powers, which had never hitherto been exercised, opposition might spring up, from State jealousy and local policy, which, in the real weakness of the federal government, would be as effectual a barrier as the want of constitutional authority. Still the effort was to be made; and Hamilton approached the subject with all the sagacity and statesmanship for which he was so distinguished. He saw that the Confederation contained provisions which looked to the continuance of the Union after the war had terminated, and that these provisions required practical application, through a machinery which had never been even framed. The Articles of Confederation vested in Congress the exclusive management of foreign relations; but the department of foreign affairs had never been properly organized. They also gave to Congress the exclusive regulation of trade and intercourse with the Indian nations; but no department of Indian affairs had been established with properly defined powers and duties. Nothing had been done to carry out the provision for fixing the standard of weights and measures throughout the United States, or to regulate the alloy and value of coin. Above all, the great question of means, military and naval, for the external and internal defence of the country during peace, for the preservation of tranquillity, the protection of commerce, the fulfilment of treaty stipulations, and the maintenance of the authority of the United States, had not been so much as touched. To regulate these important subjects was the design of a committee, at the head of which Hamilton was placed; and his earliest attention was directed to the most serious and difficult of them,--the provision for a peace establishment of military and naval forces.[197]
