The republic of Columbia is, with Mexico and Guatemala, the only state of Spanish America which occupies at once the coasts opposite to Europe and to Asia. From Cape Paria to the western extremity of Veragua is a distance of 400 sea leagues: and from Cape Burica to the mouth of Rio Tumbez the distance is 260. The shore possessed by the republic of Columbia consequently equals in length the line of coasts extending from Cadiz to Dantzic, or from Ceuta to Jaffa. This immense resource for national industry is combined with a degree of cultivation of which the importance has not hitherto been sufficiently acknowledged. The isthmus of Panama forms part of the territory of Columbia, and that neck of land, if traversed by good roads and stocked with camels, may one day serve as a portage for the commerce of the world, even though the plains of Cupica, the bay of Mandinga or the Rio Chagre should not afford the possibility of a canal for the passage of vessels proceeding from Europe to China,* or from the United States to the north-west coast of America. (* The old vice-royalty of Buenos Ayres extended also along a small portion of the South Sea coast.)
When considering the influence which the configuration of countries (that is, the elevation and the form of coasts) exercises in every district on the progress of civilization and the destiny of nations, I have pointed out the disadvantages of those vast masses of triangular continents, which, like Africa and the greater part of South America, are destitute of gulfs and inland seas. It cannot be doubted that the existence of the Mediterranean has been closely connected with the first dawn of human cultivation among the nations of the west, and that the articulated form of the land, the frequency of its contractions and the concatenation of peninsulas favoured the civilization of Greece, Italy, and perhaps of all Europe westward of the meridian of the Propontis. In the New World the uninterruptedness of the coasts and the monotony of their straight lines are most remarkable in Chili and Peru. The shore of Columbia is more varied, and its spacious gulfs, such as that of Paria, Cariaco, Maracaybo, and Darien, were, at the time of the first discovery better peopled than the rest and facilitated the interchange of productions. That shore possesses an incalculable advantage in being washed by the Caribbean Sea, a kind of inland sea with several outlets, and the only one pertaining to the New Continent. This basin, whose various shores form portions of the United States, of the republic of Columbia, of Mexico and several maritime powers of Europe, gives birth to a peculiar and exclusively American system of trade. The south-east of Asia with its neighbouring archipelago and, above all, the state of the Mediterranean in the time of the Phoenician and Greek colonies, prove that the nearness of opposite coasts, not having the same productions and not inhabited by nations of different races, exercises a happy influence on commercial industry and intellectual cultivation. The importance of the inland Caribbean Sea, bounded by Venezuela on the south, will be further augmented by the progressive increase of population on the banks of the Mississippi; for that river, the Rio del Norte and the Magdalena are the only great navigable streams which the Caribbean Sea receives. The depth of the American rivers, their immense branches, and the use of steam-boats, everywhere facilitated by the proximity of forests, will, to a certain extent, compensate for the obstacles which the uniform line of the coasts and the general configuration of the continent oppose to the progress of industry and civilization.
On comparing the extent of the territory with the absolute population, we obtain the result of the connection of those two elements of public prosperity, a connection that constitutes the relative population of every state in the New World. We shall find to every square sea league, in Mexico, 90; in the United States, 58; in the republic of Columbia, 30; and in Brazil, 15 inhabitants; while Asiatic Russia furnishes 11; the whole Russian Empire, 87; Sweden with Norway, 90; European Russia, 320; Spain, 763; and France, 1778. But these estimates of relative population, when applied to countries of immense extent, and of which a great part is entirely uninhabited, merely furnish mathematical abstractions of but little value. In countries uniformly cultivated—in France, for example—the number of inhabitants to the square league, calculated by separate departments, is in general only a third, more or less, than the relative population of the sum of all the departments. Even in Spain the deviations from the average number rise, with few exceptions, only from half to double. In America, on the contrary, it is only in the Atlantic states, from South Carolina to New Hampshire, that the population begins to spread with any uniformity. In that most civilized portion of the New World, from 130 to 900 inhabitants are reckoned to the square league, while the relative population on all the Atlantic states, considered together, is 240. The extremes (North Carolina and Massachusetts) are only in the relation of 1 to 7, nearly as in France, where the extremes, in the departments of the Hautes Alpes and the Cote-du-Nord are also in the relation of 1 to 6.7. The variations from the average number, which we generally find restricted to narrow limits in the civilized countries of Europe, exceed all measure in Brazil, in the Spanish colonies and even in the confederation of the United States, in its whole extent. We find in Mexico in some of the intendencias, for example, La Sonora and Durango, from 9 to 15 inhabitants to the square league, while in others, on the central table-land, there are more than 500. The relative population of the country situated between the eastern bank of the Mississippi and the Atlantic states is scarcely 47; while that of Connecticut, Rhode 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.
As in political economy numerical statements become instructive only by a comparison with analogous facts I have carefully examined what, in the present state of the two continents, might be considered as a small relative population in Europe, and a very great relative population in America. I have, however, chosen examples only from among the provinces which have a continued surface of more than 600 square leagues in order to exclude the accidental accumulations of population which occur around great cities; for instance, on the coast of Brazil, in the valley of Mexico, on the table-lands of Santa Fe de Bogota and Cuzco; or finally, in the smaller West India Islands (Barbadoes, Martinique and St. Thomas) of which the relative population is from 3000 to 4700 inhabitants to the square league, and consequently equal to the most fertile parts of Holland, France and Lombardy.
