The powerful union of North America has long been insulated and without contact with any states having analogous institutions. Although the progress America is making from east to west is considerably retarded near the right bank of the Mississippi, she will advance without interruption towards the internal provinces of Mexico, and will there find a European people of another race, other manners, and a different religious faith. Will the feeble population of those provinces, belonging to another dawning federation, resist; or will it be absorbed by the torrent from the east and transformed into an Anglo-American state, like the inhabitants of Lower Louisiana? The future will soon solve this problem. On the other hand, Mexico is separated from Columbia only by Guatimala, a country and extreme fertility which has recently assumed the denomination of the republic of Central America. The political divisions between Oaxaca and Chiapa, Costa Rica and Veragua, are not founded either on the natural limits or the manners and languages of the natives, but solely on the habit of dependence on the Spanish chiefs who resided at Mexico, Guatimala or Santa Fe de Bogota. It seems natural that Guatimala should one day join the isthmuses of Veragua and Panama to the isthmus of Costa Rica; and that Quito should connect New Grenada with Peru, as La Paz, Charcas and Potosi link Peru with Buenos-Ayres. The intermediate parts from Chiapa to the Cordilleras of Upper Peru form a passage from one political association to another, like those transitory forms which link together the various groups of the organic kingdom in nature. In neighbouring monarchies the provinces that adjoin each other present those striking demarcations which are the effect of great centralization of power in federal republics, states situated at the extremities of each system are some time before they acquire a stable equilibrium. It would be almost a matter of indifference to the provinces between Arkansas and the Rio del Norte whether they send their deputies to Mexico or to Washington. Were Spanish America one day to show a more uniform tendency towards the spirit of federalism, which the example of the United States has created on several points, there would result from the contact of so many systems or groups of states, confederations variously graduated. I here only touch on the relations that arise from this assemblage of colonies on an uninterrupted line of 1600 leagues in length. We have seen in North America, one of the old Atlantic states divided into two, and each having a different representation. The separation of Maine and Massachusetts in 1820 was effected in the most peaceable manner. Schisms of this kind will, it may be feared, render such changes turbulent. It may also be observed that the importance of the geographical divisions of Spanish America, founded at the same time on the relations of local position and the habits of several centuries,
