No one who candidly studies the institutions of America, and considers what it was necessary for the founders of our government to foresee and provide for, can hesitate to recognize the wisdom and the necessity of these provisions. A country of vast extent opened to a boundless immigration, which nature invited and which man could scarcely repel,--a country, too, which must be governed by popular suffrage,--could not permit its legislative halls to be invaded by foreign influence. The independence of the country would have been a vain and useless achievement, if it had not been followed by the practical establishment of the right of self-government by the native population; and that right could be secured for their posterity only by requiring that foreigners, who claimed to be regarded as a part of the people of the country, should be first amalgamated in spirit and interest with the mass of the nation. No other changes were made in the proposed qualifications for the representatives, excepting to require that the person elected should be an _inhabitant_ of the State for which he might be chosen, at the time of election, instead of being a _resident_. This change of phraseology was adopted to avoid ambiguity; the object of the provision being simply to make the representation of the State a real one. The Convention, as we have seen, had settled the rule for computing the number of inhabitants of a State, for the purposes of representation, and had made it the same with that for apportioning direct taxes among the States.[139] The committee of detail provided that there should be one representative for every forty thousand inhabitants, when Congress should find it necessary to make a new apportionment of representatives; a ratio that had not been previously sanctioned by a direct vote of the Convention, but which had been recommended by the committee of compromise, at the time when the nature of the representation in both houses was adjusted.[140] This ratio was now adopted in the article relating to the House of Representatives; but not before an effort was made to exclude the slaves from the enumeration.[141] The renewed discussion of this exciting topic probably withdrew the attention of members from the consideration of the numbers of the representatives, and nothing more was done, at the time we are now examining, than to make a provision that the number should not exceed one for every forty thousand inhabitants. But at a subsequent stage of the proceedings,[142] before the Constitution was sent to the committee of revision, Wilson, Madison, and Hamilton endeavored to procure a reconsideration of this clause, for the purpose of establishing a more numerous representation of the people. Hamilton, who had always and earnestly advocated the introduction of a strong democratic element into the Constitution, although he desired an equally strong check to that element in the construction of the Senate, is represented to have expressed himself
