one o'clock
Natalie was made comfortable in her tent ; and Garth and Charley , collecting a pile of firewood , covered it with a tarpaulin , against the coming rain . Charley , who had slept during the afternoon , was to watch until two o'clock ; and Garth , covering himself with a piece of sail-cloth , lay down at the door of the tent . It seemed to him he had no more than fallen asleep , when Charley shook his shoulder to awaken him . `` It 's one o'clock , '' the boy said . `` I think something has happened in the camp over there . They quieted down ; but now they have started up again , and have built up their fire . Looks to me as if somebody had arrived .
