Thus, whilst New Spain was always held to be nearer to the mother country than any other American lands and more of a white man's home than the settlements on the Southern Continent, the distrust engendered by the ruthless cruelty of the earlier years of the occupation contributed powerfully to retard any intimate intermixture of the conquerors and the conquered races, the closer connection with Spain also keeping the Spanish-Mexican decidedly more pure in blood than any other Spanish American people. This will account for the fact that the various Indian races of Mexico are still, to a large extent, distinct from each other and from the pure white Mexicans after nearly a century of native Republican government. In the State of Oaxaca alone there are even now at least fifteen perfectly distinguishable separate tribes of pure Indians, of which two, the Zapotecas and the Mistecas, comprise more than half the whole population of the State. But, this notwithstanding, no race question now really exists in Mexico. The pure-blooded Indians frequently occupy the highest positions in the State, as judges, soldiers, or savants, the greatest but one of Mexican Presidents, Juarez, having been a full-blooded Zapoteca, whilst the present ruler of Mexico, certainly one of the most exalted figures in American history, General Porfirio Diaz, is justifiably prouder of his Misteca descent than of the white ancestry he also claims. Nor, as in other countries of similar ethnological constitution, does the Indian population here tend to decrease. The Mexican Indian or half-breed suffers under no disability, social or political, and is in a decided majority of the population. The number of pure whites in the country is estimated at about three and a half millions, out of a probable nineteen millions of total inhabitants, eight millions being pure Indians and about seven and a half millions of mixed castes, most of whom are more brown than white. The future of the Republic, therefore, in an ethnological sense, is one of the most interesting problems of the American Continent. The old Spanish aristocratic aloofness traditional on the part of the pure whites will take many generations entirely to break down, and the increased communication between the Republic and the citizens of the United States will probably reinforce the white races with a new element of resistance to fusion; but in the end a homogeneous brown race will probably people the whole of Mexico--a race, to judge from the specimens of the admixture now in existence, capable of the highest duties of civilisation, robust in body, patriotic in character, progressive and law-abiding to a greater extent, perhaps, than are purely Latin peoples.
