These masses have so many features in common with the tepee cores that their close relationship can hardly be questioned. It is of interest to note, also, that similarity of the topographic features to which they give rise has led observers of the most diverse races to employ the same analogy in the bestowal of names a recent letter Dr Bell says : '' I was told that the Indians called the islets (formed of these spongy limestone masses) wigwams, and the caverns doors, so that your name tepee agrees with the name given by our Indians long ;.
