We have devoted much time and a close attention to the sketches which Mr. Catlin has brought back; and we are convinced that, severe as were the labours and privations to which he was subject, they were less than the value of this collection. Whoever will study the numerous and varied representations here given of savage life, and will reflect how complete a picture is presented of a most peculiar and unknown race, will be persuaded, we think, that no greater accession has been made to the sum of human knowledge and human entertainment, in this age and country, than is produced by this Museum. The philosophy of Indian character is revealed with curious distinctness by one portion of the paintings, while another class presents the picturesque of that existence with singular spirit. Many striking suggestions for the history of civility, and many valuable metaphysical considerations, are prompted by a survey of these illustrations of the intelligence and the instincts of this people; and any man who would taste the poetry of this wild life, will find enough to satisfy him in the animated exhibitions of the hunt, the march, and the fight, which are here brought before his eyes. In Mr. Irving's very graphic descriptions of the amusements of the prairie, there is nothing half so bold and stirring as the noble pictures which here bring the adventures of the buffalo-hunt before us, or the terrors of the fight with the grisly bear. ----*---- THE PENNSYLVANIAN.
