six o'clock
But the sleep had served him well and he found his mind active and his limbs rested and his belly crying for food . He poked about and at last saw something dim that thrust out of the dark on the ground , and then it got brighter , and he marked low down , no higher than his knee , a blue ghost of light shooting through some cleft among the stones . It waxed until he could put down his watch and read the hands by it . And he found it was past six o'clock . He set to work at the rocks again presently , but surrounded by darkness he did n't know where to begin and knew that a hungry man , with nought but his two hands , could make no great impression on all that stone ; but he turned where the ray came through and putting his head to the earth , found there was a narrow channel out to the daylight , and wished he could take shape of a badger and so get through . Time dragged and hope waned . But the water proved a source of strength , and Amos knew a man can hold out a long time if water ba n't denied .
