pressed on, and higher, and at last began to crawl up the _vallum_, on hands and knees, grasping the turf and here and there the roots that had burst through the red earth. And then he lay, panting with deep breaths, on the summit. Within the fort it was all dusky and cool and hollow; it was as if one stood at the bottom of a great cup. Within, the wall seemed higher than without, and the ring of oaks curved up like a dark green vault. There were nettles growing thick and rank in the foss; they looked different from the common nettles in the lanes, and Lucian, letting his hand touch a leaf by accident, felt the sting burn like fire. Beyond the ditch there was an undergrowth, a dense thicket of trees, stunted and old, crooked and withered by the winds into awkward and ugly forms; beech and oak and hazel and ash and yew twisted and so shortened and deformed that each seemed, like the nettle, of no common kind. He began to fight his way through the ugly growth, stumbling and getting hard knocks from the rebound of twisted boughs. His foot struck once or twice against something harder than wood, and looking down he saw stones white with the leprosy of age, but still showing the work of the axe. And farther, the roots of the stunted trees gripped the foot-high relics of a wall; and a round heap of fallen stones nourished rank, unknown herbs, that smelt poisonous. The earth was black and unctuous, and bubbling under the feet, left no track behind. From it, in the darkest places where the shadow was thickest, swelled the growth of an abominable fungus, making the still air sick with its corrupt odour, and he shuddered as he felt the horrible thing pulped beneath his feet. Then there was a gleam of sunlight, and as he thrust the last boughs apart, he stumbled into the open space in the heart of the camp. It was a lawn of sweet close turf in the center of the matted brake, of clean firm earth from which no shameful growth sprouted, and near the middle of the glade was a stump of a felled yew-tree, left untrimmed by the woodman. Lucian thought it must have been made for a seat; a crooked bough through which a little sap still ran was a support for the back, and he sat down and rested after his toil. It was not really so comfortable a seat as one of the school forms, but the satisfaction was to find anything at all that would serve for a chair. He sat there, still panting after the climb and his struggle through the dank and jungle-like thicket, and he felt as if he were growing hotter and hotter; the sting of the nettle was burning his hand, and the tingling fire seemed to spread all over his body.
