The early, strong and continued exertions which were made by the conquerors to replace this system of gross superstition and idolatry, by the Romish ritual, filled Mexico and South America with missions of the Catholic Church, which were generally under the charge of zealous and sometimes of learned and liberal-spirited superintendants, who have accumulated facts respecting the character and former condition of the race. These missions, which were generally spread parallel to the sea coasts of the Atlantic and Pacific, reaching inland along the banks of the great rivers and plains, have confessedly done much to ameliorate the manners and condition of the native race, to foster a spirit of industry, and to enlighten their minds. Still, it is scarcely known, that numerous and powerful tribes, stretching through wide districts of the Andes and the Cordilleras, never submitted to the conqueror, and yet exist in their original state of barbarism. In this department of inquiry, the geographical and historical work of De Alcedo, which, so far as the Spanish and Portuguese missions are concerned, is both elaborate and complete in its details, has been taken as a basis. No one can write of South America and its native tribes, without reference to Humboldt. Other standard writers have been consulted, to give this part of the work as much value as possible, not excepting the latest voyages and travels. The design has been, without aiming at too much, to compress a body of leading and characteristic facts, in the shortest practicable compass, which should, at the same time, present an ethnological view of the various families and groups of the race. In each department of inquiry, which admitted of it, the author has availed himself of such sources and opportunities of personal observation and experience, as his long residence in the Indian territories, and his study of the Indian history have afforded. And he is not without the hope, that his inquiries and researches on this head may be found to be such as to merit approval. A. AB, often pronounced with the sound of we, before it,--a particle which, in geographical names, in the family of the Algonquin dialects, denotes light, or the east. It is also the radix of the verb wab, to see, as well as of the derivatives, a-ab, an eye-ball, and wabishka, a white substance, &c.,--ideas which either in their origin or application, are closely allied.
