five o'clock
That afternoon was reminiscent of the long days on the dhow , when nobody could move without disturbing everybody else , and we all breathed the same hot mixed stench over and over . We posted two sentries to lie with their eyes on the level of the rim and guard against surprise . But there was so little to watch , except kites wheeling overhead everlastingly , that they went to sleep ; and we were so bored , and so sure of our hiding-place and Schillingschen 's unsuspicion that we did not notice them . I myself fell asleep toward five o'clock , and when I awoke the sun was so low in the west that our hollow lay in deep gloom . Fred was lying on his elbow , sucking an unfilled , unlighted pipe . Will lay on his side , too , with back toward both of us , ruminating . Coutlass and Brown were both asleep , but Coutlass awoke as I rolled over and struck him with my heel .
