Pencroft and Herbert penetrated quite far in among the rocks, by sandy passages in which light was not wanting, for it entered through the openings which were left between the blocks, of which some were only sustained by a miracle of equilibrium; but with the light came also air--a regular corridor-gale--and with the wind the sharp cold from the exterior.
Pencroff et Harbert s'engagèrent assez profondément entre les roches, dans ces couloirs sablés, auxquels la lumière ne manquait pas, car elle pénétrait par les vides que laissaient entre eux ces granits, dont quelques-uns ne se maintenaient que par un miracle d'équilibre.
