Suddenly there was no ground under me. I felt myself revolving in air, striking and rebounding against the craggy projections of a vertical gallery, quite a well; my head struck against a sharp corner of the rock, and I became unconscious.
De repente, el terreno faltó bajo mis pies, y me sentí caer, rebotando sobre las asperezas de una galería vertical, de un verdadero pozo: mi cabeza chocó contra una roca aguda, y perdí el conocimiento.
