§9. But the advantages of this arrangement are more unequal than may at first sight appear, or than was anticipated by the framers of the constitution. The benefits are chiefly on the side of the slaveholding states. In the first place, two-fifths of a large class of property in these states is exempt from taxation, while _all_ the property in the free states is liable to taxation. Of this the framers were aware. But they did not foresee the fact, that the laying of direct taxes would be unnecessary, and that the slave states would consequently escape taxation for their slaves. Only three direct taxes have been laid; and it is not probable that another will become necessary; the treasury being supplied from other sources, chiefly by duties on imports. §10. Now, although nothing is gained by the slave states, nor is anything lost by the free states, by the exemption of the two-fifths of the slaves from taxation, since direct taxes are unnecessary; there is a great gain to the slave states, which have between thirty and forty representatives for what their laws hold to be "property to all intents and purposes whatsoever," for which the free states have nothing in return. §11. The constitution does not limit the house to any definite number of representatives; it only declares that the number shall not exceed one for every 30,000 inhabitants. It requires an enumeration of the inhabitants every ten years; and the next congress thereafter determines the ratio of representation and the number of representatives, and apportions them among the states. The word _ratio_ signifies rate, or proportion. It here means the number or portion of the inhabitants entitled to a representative. §12. But as a representative for every 30,000 inhabitants, after the population became very numerous, would have made the house too large to transact business with due dispatch, and would have unnecessarily increased the public expense, the ratio of representation has from time to time been increased. But to whatever number the ratio may be raised, the constitution expressly declares, that "each state shall have at least one representative." Neither Delaware nor Florida had, in 1850, a population equal to the present ratio; and without the above constitutional provision, these states would have been deprived of a representation in the house, unless congress had adopted a smaller ratio. §13. It will be seen by reference to the constitution, that the number of representatives was for the time fixed at sixty-five. After the first census, taken in 1790, the ratio was fixed at 33,000, which gave the house 106 members. After the census of 1800, the same ratio was adopted, and the number of members was 142. After 1810, the ratio was 35,000; number of members 182. After 1820, the ratio was 40,000; number of members 213. After 1830, the ratio was 47,700; number of members 240. After 1840, the ratio was 70,680; number of members 233.
