Editorial note — Chapter XVIII · : Future Condition Of Three Races—Part VII

i [ If the population continues to double every twenty-two years, as it has done for the last two hundred years, the number of inhabitants in the United States in 1852 will be twenty millions; in 1874, forty-eight millions; and in 1896, ninety-six millions. This may still be the case even if the lands on the western slope of the Rocky Mountains should be found to be unfit for cultivation. The territory which is already occupied can easily contain this number of inhabitants. One hundred millions of men disseminated over the surface of the twenty-four States, and the three dependencies, which constitute the Union, would only give 762 inhabitants to the square league; this would be far below the mean population of France, which is 1,063 to the square league; or of England, which is 1,457; and it would even be below the population of Switzerland, for that country, notwithstanding its lakes and mountains, contains 783 inhabitants to the square league.
