n Mr. Curtis we have both an artist and a trained observer, whose pictures are pictures, not merely photographs; whose work has far more than mere accuracy, because it is truthful. All serious students are to be congratulated because he is putting his work in permanent form; for our generation offers the last chance for doing what Mr. Curtis has done. The Indian as he has hitherto been is on the point of passing away. His life has been lived under conditions thru which our own race past so many ages ago that not a vestige of their memory remains. It would be a veritable calamity if a vivid and truthful record of these conditions were not kept. No one man alone could preserve such a record in complete form. Others have worked in the past, and are working in the present, to preserve parts of the record; but Mr. Curtis, because of the singular combination of qualities with which he has been blest, and because of his extraordinary success in making and using his opportunities, has been able to do what no other man ever has done; what, as far as we can see, no other man could do. He is an artist who works out of doors and not in the closet. He is a close observer, whose qualities of mind and body fit him to make his observations out in the field, surrounded by the wild life he commemorates. He has lived on intimate terms with many different tribes of the mountains and the plains. He knows them as they hunt, as they travel, as they go about their various avocations on the march and in the camp. He knows their medicine men and sorcerers, their chiefs and warriors, their young men and maidens. He has not only seen their vigorous outward existence, but has caught glimpses, such as few white men ever catch, into that strange spiritual and mental life of theirs; from whose innermost recesses all white men are forever barred. Mr. Curtis in publishing this book is rendering a real and great service; a service not only to our own people, but to the world of scholarship everywhere.
