[42] The important consideration in the mind of primitive man was whether certain things were harmful or useful. See Behaghel, Die deutsche Sprache, p. 98:—“Die grossen Tiere und die mächtigen Bäume, die Tiere und Pflanzen, die für die _Ernährung_ and _Bekleidung_ des Menschen von Bedeutung sind, die Tiere, die sein Leben _bedrohen_, sie haben viel früher sprachliche Bezeichnung gefunden, als der unscheinbare Käfer im Sande, als die kleine Blume des Waldes. So kommt es, dass die Namen der grösseren Tiere, der grossen Waldbäume, der wichtigsten Getreidearten allen germanischer Stämmen gemeinsam sind, einzelne sogar, wie _Wolf_, _Kuh_, _Ochse_, _Birke_, _Buche_, _Erle_, _Gerste_ mit den Benennungen anderer indogermanischer Völker übereinstimmen.” Doubtless animals occupied their attention sooner than plants. See Wundt, Völkerpsychologie, II. 412 fol., about the _maskentanz_: “Überhaupt haben die Tiermotive weit früher Berücksichtigung erfahren als die Pflanzenmotive.” See note 95. Fourthly, primitive man would put on an animal’s skin or dress when out as _forager_ (or robber) or _spy_, for the purpose of avoiding detection by the enemy. The Pawnee Indians for example,[43] were called by neighboring tribes _wolves_, probably not out of contempt, since it may be doubted that an Indian feels contempt for a wolf any more than he does for a fox, a rabbit, or an elk, but because of their adroitness as scouts, warriors and stealers of horses; or, as the Pawnees think, because of their great endurance, their skill in imitating wolves so as to escape detection by the enemy by day or night; or, according to some neighboring tribes, because they prowl like wolves[44], “have the endurance of wolves, can travel all day and dance all night, can make long journeys, living on the carcasses they find on their way, or on no food at all.” ... And further, “The Pawnees, when they went on the warpath, were always prepared to simulate wolves.... Wolves on the prairie were too common[45] to excite remark, and at night they would approach close to the Indian camps.” ... The Pawnee starting off on the warpath usually carried a robe made of wolf skins, or in later times a white blanket or a white sheet; and, at _night_, wrapping himself in this, and getting down on his hands and knees, he walked or trotted here and there like a wolf, having thus transformed himself into a common object of the landscape. This disguise was employed by _day_ as well, for reconnoissance.... While the party remained hidden in some ravine or hollow, one Indian would put his robe over him and gallop to the top of the hill on all fours, and would sit there on his haunches looking all over the country, and anyone at a distance who saw him, would take him for a wolf. It was acknowledged on all hands that the Pawnees could imitate wolves best. “An Indian going into an enemy’s
