island, and Massachusetts is more than 800. Westward of the Mississippi as well as in the interior of Spanish Guiana there are not two inhabitants to the square league over much larger extents of territory than Switzerland or Belgium. The state of these countries is like that of the Russian Empire, where the relative population of some of the Asiatic governments (Irkutsk and Tobolsk) is to that of the best cultivated European districts as 1 to 300. The enormous difference existing, in countries newly cultivated, between the extent of territory and the number of inhabitants, renders these partial estimates necessary. When we learn that New Spain and the United States, taking their entire extent at 75,000 and 174,000 square sea-leagues, give respectively 90 and 58 souls to each league, we no more obtain a correct idea of that distribution of the population on which the political power of nations depends, than we should of the climate of a country, that is to say, of the distribution of the heat in the different seasons, by the mere knowledge of the mean temperature of the whole year. If we take from the United States all their possessions west of the Mississippi, their relative population would be 121 instead of 58 to the square league; consequently much greater than that of New Spain. Taking from the latter country the Provincias internas (north and north-east of Nueva Galicia) we should find 190 instead of 90 souls to the square league. The provinces of Caracas, Maracaybo, Cumana and Barcelona, that is, the maritime provinces of the north, are the most populous of the old Capitania-General of Caracas; but, in comparing this relative population with that of New Spain, where the two intendencias of Mexico and Puebla alone contain, on an extent scarcely equal to the superficies of the province of Caracas, a greater population than that of the whole republic of Columbia, we see that some Mexican intendencias which, with respect to the concentration of their culture, occupy but the seventh or eighth rank (Zacatecas and Guadalajara), contain more inhabitants to the square league than the province of Caracas. The average of the relative population of Cumana, Barcelona, Caracas and Maracaybo, is fifty-six; and, as 6200 square leagues, that is, one half of the extent of these four provinces are almost desert Llanos, we find, in reckoning the superficies and the scanty population of the plains, 102 inhabitants to the square league. An analogous modification gives the province of Caracas alone a relative population of 208, that is, only one-seventh less than that of the Atlantic States of North America.
