The missionaries usually refused to preserve the native myths, because they believed them harmful, or at least foolish; while men of science, who have had such opportunities, rejected all those that seemed the least like a Biblical story, as they suspected them to be modern and valueless compositions, and thus lost the very life of the genuine ancient faiths.
A further disadvantage is the slight attention which has been paid to the aboriginal American tongues, and the sad deficiency of material for their study.

It is now recognized on all hands that the key of a mythology is to be found in the language of its believers.

As a German writer remarks, "the formation of the language and the evolution of the myth go hand in hand."[1] We must know the language of a tribe, at least we must understand the grammatical construction and have facilities to trace out the meaning and derivation of names, before we can obtain any accurate notion of the foundation in nature of its religious beliefs.

No convenient generality will help us.
[Footnote 1: "In der Sprache herrscht immer und erneut sich stets die sinnliche Anschauung, die vor Jahrtausenden mit dem glaeubigen Sinn vermaehlt die Mythologien schuf, und gerade durch sie wird es am klarsten, wie Sprachenschoepfung und mythologische Entwicklung, der Ausdruck des Denkens und Glaubens, einst Hand in Hand gegangen."
