'There are no adventures South the Wall,' said Parnesius. 'The worst thing that happened me was having to appear before a magistrate up North, where a wandering philosopher had jeered at the Eagles. I was able to show that the old man had deliberately blocked our road; and the magistrate told him, out of his own Book, I believe, that, whatever his Gods might be, he should pay proper respect to Caesar.' 'What did you do?' said Dan. 'Went on. Why should I care for such things, my business being to reach my station? It took me twenty days. 'Of course, the farther North you go the emptier are the roads. At last you fetch clear of the forests and climb bare hills, where wolves howl in the ruins of our cities that have been. No more pretty girls; no more jolly magistrates who knew your Father when he was young, and invite you to stay with them; no news at the temples and way-stations except bad news of wild beasts. There's where you meet hunters, and trappers for the Circuses, prodding along chained bears and muzzled wolves. Your pony shies at them, and your men laugh. 'The houses change from gardened villas to shut forts with watch-towers of grey stone, and great stone-walled sheepfolds, guarded by armed Britons of the North Shore. In the naked hills beyond the naked houses, where the shadows of the clouds play like cavalry charging, you see puffs of black smoke from the mines. The hard road goes on and on--and the wind sings through your helmet-plume--past altars to Legions and Generals forgotten, and broken statues of Gods and Heroes, and thousands of graves where the mountain foxes and hares peep at you. Red-hot in summer, freezing in winter, is that big, purple heather country of broken stone. 'Just when you think you are at the world's end, you see a smoke from East to West as far as the eye can turn, and then, under it, also as far as the eye can stretch, houses and temples, shops and theatres, barracks and granaries, trickling along like dice behind--always behind--one long, low, rising and falling, and hiding and showing line of towers. And that is the Wall!' 'Ah!' said the children, taking breath. 'You may well,' said Parnesius. 'Old men who have followed the Eagles since boyhood say nothing in the Empire is more wonderful than first sight of the Wall!'
