'No, no! It is the Wall. Along the top are towers with guard-houses, small towers, between. Even on the narrowest part of it three men with shields can walk abreast, from guard-house to guard-house. A little curtain wall, no higher than a man's neck, runs along the top of the thick wall, so that from a distance you see the helmets of the sentries sliding back and forth like beads. Thirty feet high is the Wall, and on the Picts' side, the North, is a ditch, strewn with blades of old swords and spear-heads set in wood, and tyres of wheels joined by chains. The Little People come there to steal iron for their arrow-heads.
'But the Wall itself is not more wonderful than the town behind it. Long ago there were great ramparts and ditches on the South side, and no one was allowed to build there. Now the ramparts are partly pulled down and built over, from end to end of the Wall; making a thin town eighty miles long. Think of it! One roaring, rioting, cock-fighting, wolf-baiting, horse-racing town, from Ituna on the West to Segedunum on the cold eastern beach! On one side heather, woods and ruins where Picts hide, and on the other, a vast town - long like a snake, and wicked like a snake. Yes, a snake basking beside a warm wall!
'My Cohort, I was told, lay at Hunno, where the Great North Road runs through the Wall into the Province of Valentia.'Parnesius laughed scornfully. 'The Province of Valentia! We followed the road, therefore, into Hunno town, and stood astonished. The place was a fair - a fair of peoples from every corner of the Empire. Some were racing horses: some sat in wine-shops: some watched dogs baiting bears, and many gathered in a ditch to see cocks fight. A boy not much older than myself, but I could see he was an officer, reined up before me and asked what I wanted.
"'My station," I said, and showed him my shield.'
Parnesius held up his broad shield with its three X's like letters on a beer-cask.
"'Lucky omen!" said he. "Your Cohort's the next tower to us, but they're all at the cock-fight. This is a happy place. Come and wet the Eagles." He meant to offer me a drink.
"'When I've handed over my men," I said. I felt angry and ashamed.
"'Oh, you'll soon outgrow that sort of nonsense," he answered. "But don't let me interfere with your hopes.
Go on to the Statue of Roma Dea. You can't miss it. The main road into Valentia!" and he laughed and rode off. I could see the statue not a quarter of a mile away, and there I went. At some time or other the Great North Road ran under it into Valentia; but the far end had been blocked up because of the Picts, and on the plaster a man had scratched, "Finish!" It was like marching into a cave.
We grounded spears together, my little thirty, and it echoed in the barrel of the arch, but none came. There was a door at one side painted with our number. We prowled in, and I found a cook asleep, and ordered him to give us food. Then I climbed to the top of the Wall, and looked out over the Pict country, and I - thought,' said Parnesius. 'The bricked-up arch with "Finish!" on the plaster was what shook me, for I was not much more than a boy.'
'What a shame!'said Una. 'But did you feel happy after you'd had a good -'Dan stopped her with a nudge.
'Happy?' said Parnesius. 'When the men of the Cohort I was to command came back unhelmeted from the cock-fight, their birds under their arms, and asked me who I was? No, I was not happy; but I made my new Cohort unhappy too ... I wrote my Mother I was happy, but, oh, my friends'- he stretched arms over bare knees - 'I would not wish my worst enemy to suffer as I suffered through my first months on the Wall. Remember this: among the officers was scarcely one, except myself (and I thought I had lost the favour of Maximus, my General), scarcely one who had not done something of wrong or folly. Either he had killed a man, or taken money, or insulted the magistrates, or blasphemed the Gods, and so had been sent to the Wall as a hiding-place from shame or fear. And the men were as the officers. Remember, also, that the Wall was manned by every breed and race in the Empire. No two towers spoke the same tongue, or worshipped the same Gods. In one thing only we were all equal. No matter what arms we had used before we came to the Wall, on the Wall we were all archers, like the Scythians. The Pict cannot run away from the arrow, or crawl under it. He is a bowman himself. He knows!'
'I suppose you were fighting Picts all the time,' said Dan.
'Picts seldom fight. I never saw a fighting Pict for half a year. The tame Picts told us they had all gone North.'
'What is a tame Pict?' said Dan.
'A Pict - there were many such - who speaks a few words of our tongue, and slips across the Wall to sell ponies and wolf-hounds. Without a horse and a dog, and a friend, man would perish. The Gods gave me all three, and there is no gift like friendship. Remember this' -
Parnesius turned to Dan -'when you become a young man. For your fate will turn on the first true friend you make.'
'He means,' said Puck, grinning, 'that if you try to make yourself a decent chap when you're young, you'll make rather decent friends when you grow up. If you're a beast, you'll have beastly friends. Listen to the Pious Parnesius on Friendship!'
'I am not pious,'Parnesius answered, 'but I know what goodness means; and my friend, though he was without hope, was ten thousand times better than I. Stop laughing, Faun!'
'Oh, Youth Eternal and All-believing,' cried Puck, as he rocked on the branch above. 'Tell them about your Pertinax.'
'He was that friend the Gods sent me - the boy who spoke to me when I first came. Little older than myself, commanding the Augusta Victoria Cohort on the tower next to us and the Numidians. In virtue he was far my superior.'
'Then why was he on the Wall?' Una asked, quickly.
'They'd all done something bad. You said so yourself.'
'He was the nephew, his father had died, of a great rich man in Gaul who was not always kind to his mother.
When Pertinax grew up, he discovered this, and so his uncle shipped him off, by trickery and force, to the Wall.
