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 y Harbert se internaron bastante profundamente entre las rocas, por aquellos corredores areniscos, a los cuales no faltaba luz, porque penetraba por los huecos que dejaban entre sí los trozos de granito, algunos de los cuales se mantenían por verdadero milagro en equilibrio.
