"You know what the words mean," he said. "Strictly speaking, it's the summer-house--pavilion--shelter--of a night. The essentials are that it must be built on common land, and in a single night. Then they can't eject you. At least that's the idea. Don't ask me how it stands in Law. It may be a kind of squatter's right, or anything else, or it may have no standing at all. Probably it hasn't. But that's neither here nor there. They have their notions about it, and those at any rate are immemorial. Look here: you're pottering about this country just now; just count how many houses you find with the name 'Hafod Unos.' You'll find quite a lot. There's a very big one Bangor way, that probably took some years to build, but probably one of these places was its foundation.... And a house 'within the meaning of the Act,' so to speak, means that smoke must have gone up the chimney. Cook your breakfast there, and--well, after that you're a sort of tolerated freeholder. It might be worth putting into your Guide Book. You'd better add a footnote, though, that the 'f' in 'hafod' is a 'v,' and 'unos' is pronounced 'innos.' ... Not at all; you're welcome to any help I can give you----" * * * * * Llanyglo, snugly in bed, had heard the sounds across the sandhills during the night, but they had been set down to the newest development of the fencing dispute. This development was that, a week or so before, several cartloads of undressed stone had been shot down by the side of the sandy gully that ran from Pritchard's gap down to the shore. And Llanyglo had smiled. Aha! They were going to build a walled enclosure, were they? Something that wouldn't burn, whatever? Well, well, if it amused them to build walls on winter nights when everybody else was warm in bed, they might. They would only lose their labour in the end. Mr. Tudor Williams, of Ponteglwys, was going to ask a question in the House of Commons, yes, and he was coming down to speak at the Chapel and to see for himself. It was a cold night for building walls, whatever---- So they stayed in bed, and only the revolving Trwyn light, two reds and a white, saw the planting of the thorn in Llanyglo's side.
