'You don't mean to say that he would actually steal it?' queried his wife, aghast. 'Wouldn't he, though? He'd lift anything that was not too heavy or too hot,' retorted her husband. The next day proved to be a lovely autumn morning, and the prospect along the Wall perfect for the antiquary, who could see it crawling like some great serpent on its belly, with many an undulation from east to west, over many a mile beneath the racing clouds and sunshine. Turnbull walked down to meet the party of excursionists beside a newly excavated mile-castle where they were to eat their sandwiches and discuss their theories. After that he was to conduct them to his house 'The Crag,' and show them his altar and give them refreshment. Turnbull took the very earliest opportunity of informing them of his 'find,' and while his friends congratulated him Mr. Telfer opined that its discovery proved nothing as to a camp, for a portable altar might easily be discovered anywhere along the Wall, and there was no record of any camp at that particular spot. 'The spade will show,' cried 'Plain Tom,' triumphantly. 'It's just my first-fruits. Wait a few weeks and my spade will prove it.' Almost at once the party moved onwards, for they had an early train to catch, and as soon as they reached the house tea was set before them, and their host handed round the altar for inspection. 'Pity there's no record on it to show to what God it was dedicated,' said one, 'and by whom.' 'It probably belonged to some pioneers along the Wall who built themselves a temporary camp whilst prospecting,' said Turnbull. Telfer, on the other hand, was of opinion that the altar was not of the local freestone, had probably been brought from a neighbouring camp, and eventually thrown away when the Picts and Scots overran the Wall. 'If you'll show me the place where you found it,' he added, 'I can prove to you, I think, that the surrounding stone is different.' 'My pioneers probably imported it,' said the other boldly, 'but the kind of stone is neither here nor there. However, I'll gladly show you the identical spot where I howked it out.' While the rest of the party made their way down the valley towards the railway station, 'Plain Tom' went off with his sceptic to the place of excavation. 'There,' said he, pointing to the spot, 'that's where it came from,' and as he spoke he turned over with his spade some debris that had fallen into the hole. His companion took up a fragment of stone, examined it, shook his head, then proceeded to 'howk' out with his stick a stone of some size lying half-bedded in the earth at the bottom of the hole. He levered it away, and it rolled over on its side; something glittered beneath. 'Ha! an aureus!' cried the attorney, and dashed upon it. 'I told you so, I told you so,' shouted his host in triumphant joy. 'This proves it!'
