twenty-five minutes past eight
I often looked at the instruments hanging from the partition . The manometer showed that the Nautilus kept at a constant depth of more than three hundred yards ; the compass still pointed to south ; the log indicated a speed of twenty miles an hour , which , in such a cramped space , was very great . But Captain Nemo knew that he could not hasten too much , and that minutes were worth ages to us . At twenty-five minutes past eight a second shock took place , this time from behind . I turned pale . My companions were close by my side . I seized Conseil 's hand .
