_Catlin's Indian Gallery._--We cannot notice this collection too often. It is one of those productions which illustrate, in an eminent degree, the observation of Playfair, that when the proper time has arrived for some great work to be performed, some individual is raised up by Providence whose position and character and capacity precisely fit him for accomplishing the design. For reasons that will be appreciated by the philosopher, the philanthropist, and the theologian, as well as considerations that address themselves to the curiosity of the man of general knowledge, it was particularly desirable that a full and authentic record should be given to the world of the national characteristics of a race whose history is so peculiar, whose condition is so curious, and whose speedy extinguishment is so certain, as those of the North American Indians. Accordingly, when it is plain that the moment has arrived beyond which the portraiture of their state cannot any longer be delayed, if it would be known that they are in that native predicament which has been in nowise modified by European intercourse, a man appears whose birth in a spot of which the traditions are so strongly interfused with the memory of the Indian (the Wyoming Valley), has caused his imagination to be deeply impressed, even from his earliest youth, by the character and actions of this people; who is endowed by nature with the hand and eye of a painter, and who passes through a professional education which advances his talent to the skill of an accomplished artist, and who has inherited a fortitude of spirit, an elevation of purpose, and a vigour of limb, which render him competent to encounter the dangers, the discouragements, and the difficulties which of necessity lie along the path to the object in question. The man is willing to devote the best years of his life to the task of working out a great picture of those tribes of savages which are separated by 2000 miles from the farthest settlement of his nation.
