Mr. James H. Blodgett, of the U. S. Geological Survey, calls attention to the paintings on the rocks of the bluffs of the Mississippi River, a short distance below the mouth of the Illinois River, in Illinois, which were observed by early French explorers, and have been the subject of discussion by much more recent observers. Mr. P. W. Norris found numerous painted totemic characters upon the cliffs in the immediate vicinity of the pipestone quarry, Minnesota. These consisted, probably, of the totems or names of Indians who had visited that locality for the purpose of obtaining catlinite for making pipes. These had been mentioned by early writers. Mr. Norris also discovered painted characters upon the cliffs on the Mississippi River, 19 miles below New Albin, in northeastern Iowa. Mr. Gilbert Thompson reports his observation of pictographs at San Antonio Springs, 30 miles east of Fort Wingate, New Mexico. The human form, in various styles, occurs, as well as numerous other characters strikingly similar to those frequent in the country, farther west, occupied by the Moki Indians. The peculiarity of these figures is that the outlines are incised or etched, the depressions thus formed being filled with pigments of either red, blue, or white. The interior portions of the figures are simply painted with one or more of the same colors. Charles D. Wright, esq., of Durango, Colorado, writes that he has discovered “hieroglyphical writings” upon rocks and upon the wall of a cliff house near the Colorado and New Mexico boundary line. On the wall in one small building was found a series of characters in red and black paints, consisting of a “chief on his horse, armed with spear and lance, wearing a pointed hat and robe; behind this were about twenty characters representing people on horses, lassoing horses, etc.; in fact, the whole scene represented breaking camp and leaving in a hurry. The whole painting measured about 12 by 16 feet.” Other rock-paintings are also mentioned as occurring near the San Juan River, consisting of four characters representing men as if in the act of taking an obligation, hands extended, etc. At the right are some characters in black paint, covering a space 3 by 4 feet.
