The present volume of GUSTAVE AIMARD's works is a continuation of the "Indian Chief," and conclusion of the series comprising that work, the "Gold Seekers," and the "Tiger Slayer." At the present moment, when we are engaged in a war with Mexico, I feel assured that the extraordinary and startling descriptions given in this volume of the social condition and mode of life in the capital of that country will be read with universal gratification; for I can assert confidently that; no previous writer has ever produced such a graphic and truthful account of a city with which the illustrated papers will soon make us thoroughly acquainted.
