_Catlin's Indian Gallery._--This interesting museum of curiosities, collected by Mr. Catlin, during a residence of more than eight years among forty tribes of Indians, and of sketches painted by him, illustrative of their habits and customs, is now exhibited at the Arcade in this city. It is an eloquent and illustrious witness of the genius, disinterestedness, and toil of the person who brought it together. Those productions of Mr. Catlin's pencil, which were given to the world many years since, evinced his ability to rank, at some day, with the first artists of this country; but instead of devoting himself to those lucrative branches of his profession, which would have gained him a sure return of wealth, he resolved, at the bidding of an enthusiasm, perhaps inspired by the legends of his native valley of Wyoming, to dedicate his life to the great and generous purpose of presenting to his countrymen a satisfactory portraiture of a nation which had so interesting a connexion with their own history, and whose condition has always produced so strong an impression upon the imagination of Americans. Alone and unsupported, save by a dauntless spirit, he turned towards the western forests to seek the Indian in his boundless home. "The general garden, where all steps may roam, Whose nature owns a nation for her child, Exulting in the enjoyment of the wild." The perils of more than a Ulyssean voyage were encountered before the artist could feel that his object was accomplished, and before he would permit himself to return to his family and friends.
