Indian character

I admire Washington Iruing, because he wrote a bout the Indian character sincerely. He wrote bad and good habits of Indian and whatever he had seen during his journey truthfully.
He didn’t add some bad information about Indian to his story that he had heard. Also, I think the time of writing those stories is very important, and the point of view of Indian at that period of time effected on the story that written by Francis Parkman, He spoke about Indians bad habits in his story.So, Irving’s story can be more qualified than Parkman’s story.
