But Slavery plays the part of a Harpy, and defiles the choicest banquet. See what it does with this territory, thus spacious and fair. An important indication of prosperity is in the growth of population. In this respect the two regions started equal. In 1790, at the first census under the Constitution, the population of the present Slave States was 1,961,372, of the present Free States 1,968,455, showing a difference of only 7,083 in favor of the Free States. This difference, at first merely nominal, has been constantly increasing since, showing itself more strongly in each decennial census, until, in 1850, the population of the Slave States swollen by the annexation of three foreign Territories, Louisiana, Florida, and Texas, was only 9,612,969, while that of the Free States, without such large annexations, reached 13,434,922, showing a difference of 3,821,953 in favor of Freedom. But this difference becomes still more remarkable, if we confine our inquiries to the white population, which at this period was only 6,184,477 in the Slave States, while it was 13,238,670 in the Free States, showing a difference of 7,054,193 in favor of Freedom, and showing also that the white population of the Free States had not only doubled, but, while occupying a smaller territory, commenced to triple, that of the Slave States. The comparative sparseness of the two populations furnishes another illustration. In the Slave States the average number of inhabitants to a square mile was 11.29, while in the Free States, it was 21.93 or almost two to one in favor of Freedom. These results are general; but if we take any particular Slave State, and compare it with a Free State, we shall find the same marked evidence for Freedom. Take Virginia, with a territory of 61,352 square  miles, and New York, with a territory of 47,000, or over 14,000 square miles less than her sister State. New York has one seaport, Virginia some three or four; New York has one noble river, Virginia has several; New York for 400 miles runs along the frozen line of Canada, Virginia basks in a climate of constant felicity. But Freedom is better than climate, river, or seaport. In 790 the population of Virginia was 748,308, and in 1850 it was 1,421,661. In 1790 the population of New York was 340,120, and in 1850 it was 3,097,394. That of Virginia had not doubled in sixty years, while that of New York had multiplied more than ninefold. A similar comparison may be made between Kentucky, with 37,680 squares miles, admitted into the Union as long ago as 1792, and Ohio, with 39,964 square miles, admitted into the Union in 1802. In 1850, the Slave State had a population of only 982,405, while Ohio had a population of 1,980,329, showing a difference of nearly a million in favor of Freedom.
