He had not brought his watch , partly because he had fastened a small compass on the chain , but he knew that day would not break for some hours yet .

For all that , it was a nuisance to get up and look for dead branches in the dark , and he waited , reluctant to throw off his blanket , for some minutes , and then roused himself with a jerk . He imagined he heard voices out on the lake . He glanced at Father Lucien , but the latter was fast asleep .
