This might have been too shallow for inconvenience, it might have been deep enough for danger.

I waited till my eyes should be able to penetrate its interior; but before the light entered it I perceived, apparently growing across it, really coming gradually into view under the brightening gleam, a species of bridge which--when the twilight ceased to increase, and remained as dim as that cast by the crescent moon--assumed the outline of a slender trunk supported by wings, dark for the most part but defined along the edge by a narrow band of brightest green, visible in a gleam too faint to show any object of a deeper shade.
