It is well known that Spain contains a population composed of very dissimilar ethnical elements, and that the inhabitants of its various provinces differ essentially, not only in physical appearance, but still more in mental characteristics. As in all newly-settled countries, immigrants from the same locality are apt to select the same spot, the extensive Spanish possessions on this continent were colonized, each respectively, by some particular province in the mother country. Thus the Biscayans settled Mexico; the Andalusians and natives of the Canary Islands, Venezuela; the Catalonians, Buenos Ayres; the Castillians, Peru, etc. Although centuries have elapsed since these original settlements, and although the character of the Spanish Americans must have been variously modified by the physical nature of their new homes, whether situated in the vicinity of coasts, or of mining districts, or in isolated table-lands, or in fertile valleys; notwithstanding all this, the great traveller and experienced observer still clearly recognizes in the character of the various populations of South America, the distinctive peculiarities of the original settlers. Says he: "The Andalusians and Canarians of Venezuela, the Mountaineers and the Biscayans of Mexico, the Catalonians of Buenos Ayres, evince considerable differences in their aptitude for agriculture, for the mechanical arts, for commerce, and for all objects connected with intellectual development. _Each of these races has preserved, in the new, as in the old world, the shades that constitute its national physiognomy_; its asperity or mildness of character; its freedom from sordid feelings, or its excessive love of gain; its social hospitality, or its taste of solitude.... In the inhabitants of Caracas, Santa Fé, Quito, and Buenos Ayres, we still recognize the features that belong to the race of the first settlers."--_Personal Narrative_, Eng.
