crevice

I tapped upon the floor, but it sounded the same all over, and there was no sign of any crack or crevice.

The intrepid treasure-seeker walked round it, and, selecting the spot from whence it appeared most susceptible to attack, placed his lever in one of the crevices, and strained every nerve to move the mass.

But instead of the darkness, and the thick and mephitic atmosphere he had expected to find, Dantès saw a dim and bluish light, which, as well as the air, entered, not merely by the aperture he had just formed, but by the interstices and crevices of the rock which were visible from without, and through which he could distinguish the blue sky and the waving branches of the evergreen oaks, and the tendrils of the creepers that grew from the rocks.

A guttering candle was stuck in a crevice of the rocks which flanked it on each side so as to keep the wind from it and also to prevent it from being visible, save in the direction of Baskerville Hall.
