It is at this point that the ascent of the hill begins. The man did not return to the road to Montfermeil; he struck across the fields to the right, and entered the forest with long strides.

Once in the forest he slackened his pace, and began a careful examination of all the trees, advancing, step by step, as though seeking and following a mysterious road known to himself alone. There came a moment when he appeared to lose himself, and he paused in indecision. At last he arrived, by dint of feeling his way inch by inch, at a clearing where there was a great heap of whitish stones. He stepped up briskly to these stones, and examined them attentively through the mists of night, as though he were passing them in review. A large tree, covered with those excrescences which are the warts of vegetation, stood a few paces distant from the pile of stones. He went up to this tree and passed his hand over the bark of the trunk, as though seeking to recognize and count all the warts.
