In the Oglala Roster mentioned in Chapter XIII, Section 4, infra, one of the heads of families is called Inyanowapi, translated as Painted (or inscribed) rock. A blue object in the shape of a bowlder is connected with the man’s head by the usual line, and characters too minute for useful reproduction appear on the bowlder. The name is interesting as giving the current Dakota term for rock-inscriptions. The designation may have been given to this Indian because he was an authority on the subject and skilled either in the making or interpretation of petroglyphs. The name “Wikhegan” was and still is used by the Abnaki to signify portable communications made in daily life, as distinct from the rock carvings mentioned above, which are regarded by them as mystic. One of the curious facts in connection with petroglyphs is the meager notice taken of them by explorers and even by residents other than the Indians, who are generally reticent concerning them. The present writer has sometimes been annoyed and sometimes amused by this indifference. The resident nearest to the many inscribed rocks at Kejimkoojik Lake, Nova Scotia, described in Chapter II, Section 1, was a middle-aged farmer of respectable intelligence who had lived all his life about 3 miles from those rocks, but had only a vague notion of their character, and with difficulty found them. A learned and industrious priest, who had been working for many years on the shores of Lake Superior preparing not only a dictionary and grammar of the Ojibwa language, but an account of Ojibwa religion and customs, denied the present existence of any objects in the nature of petroglyphs in that region. Yet he had lived for a year within a mile of a very important and conspicuous pictured rock, and, on being convinced of his error by sketches shown him, called in his Ojibwa assistant and for the first time learned the common use of a large group of words which bore upon the system of picture-writing, and which he thereupon inserted in his dictionary, thus gaining from the visitor, who had come from afar to study at the feet of this supposed Gamaliel, much more than the visitor gained from him.
