two o'clock
Margit gave no sign of fatigue : but I observed that she walked alone and in silence . Indeed she had scarcely spoken since our shipwreck . The ground chosen for our halt lay about mid-way down a stiff slope by which the forest descended to the sea , visible here and there between the stems of the trees below us . Shortly before two o'clock , when we were preparing to start again , a big stone came crashing down among our stores ; and , as we scattered in alarm , two or three others followed . Looking up , I caught sight of a couple of Indians on the crest of the slope , and fired off my rifle to frighten them . They desisted at once : but to prevent further annoyance we made for the crest , where the rocky ground made walking difficult , so that we added but another five miles or so before nightfall . During this night the wind rose , and at length it blew and snowed so hard as to drive us off the ridge .
