As I had taken care to keep an exact account of our manoeuvres with the rope, which I knew that we had repeated fourteen times, each descent occupying half an hour, the conclusion was easy that we had been seven hours, plus fourteen quarters of rest, making ten hours and a half.
Como había tenido cuidado de anotar escrupulosamente las veces que cambiábamos la cuerda, pude calcular con toda exactitud la profundidad a que nos encontrábamos y el tiempo transcurrido. Habíamos repetido catorce veces esta maniobra, que duraba media hora aproximadamente.
