The American Union has now subsisted for half a century, in the course of which time its existence has only once been attacked, namely, during the war of independence. At the commencement of that long war, various occurrences took place which betokened an extraordinary zeal for the service of the country.[177] But as the contest was prolonged, symptoms of private egotism began to show themselves. No money was poured into the public treasury; few recruits could be raised to join the army; the people wished to acquire independence, but was very ill disposed to undergo the privations by which alone it could be obtained. "Tax laws," says Hamilton in the Federalist (No. 12), "have in vain been multiplied; new methods to enforce the collection have in vain been tried; the public expectation has been uniformly disappointed; and the treasuries of the states have remained empty. The popular system of administration inherent in the nature of popular government, coinciding with the real scarcity of money incident to a languid and mutilated state of trade, has hitherto defeated every experiment for extensive collections, and has at length taught the different legislatures the folly of attempting them." The United States have not had any serious war to carry on since that period. In order, therefore, to appreciate the sacrifices which democratic nations may impose upon themselves, we must wait until the American people is obliged to put half its entire income at the disposal of the government, as was done by the English; or until it sends forth a twentieth part of its population to the field of battle, as was done by France. In America the use of conscription is unknown, and men are induced to enlist by bounties. The notions and habits of the people of the United States are so opposed to compulsory enlistments, that I do not imagine that it can ever be sanctioned by the laws. What is termed the conscription in France is assuredly the heaviest tax upon the population of that country; yet how could a great continental war be carried on without it? The Americans have not adopted the British impressment of seamen, and they have nothing which corresponds to the French system of maritime conscription; the navy, as well as the merchant service, is supplied by voluntary engagement. But it is not easy to conceive how a people can sustain a great maritime war, without having recourse to one or the other of these two systems. Indeed, the Union, which has fought with some honor upon the seas, has never possessed a very numerous fleet, and the equipment of the small number of American vessels has always been excessively expensive.
