At Berwick-on-Tweed he notes the old ramparts of the town: “These, erected in Elizabeth’s time, are interesting as being, I believe, the only existing sample in England of the bastioned system of the 16th century.... The outline of the works seems perfect enough, though both earth and stone work are in great disrepair. The bastions are large with obtuse angles, square orillons, and double flanks originally casemated, and most of them crowned with cavaliers.” On the way to Durham, “much amused by the discussions of two passengers, one a smooth-spoken, semi-clerical looking person; the other a brusque well-to-do attorney with a Northumbrian burr. Subject, among others, Protection. The Attorney all for ‘cheap bread’— ‘You wouldn’t rob the poor man of his loaf,’ and so forth. ‘You must go with the _stgheam_, sir, you must go with the stgheam.’ ‘I never did, Mr. Thompson, and I never will,’ said the other in an oily manner, singularly inconsistent with the sentiment.” At Durham they dined with a dignitary of the Church, and Yule was roasted by being placed with his back to an enormous fire. “Coals are cheap at Durham,” he notes feelingly, adding, “The party we found as heavy as any Edinburgh one. Smith, indeed, evidently has had little experience of really stupid Edinburgh parties, for he had never met with anything approaching to this before.” (Happy Smith!) But thanks to the kindness and hospitality of the astronomer, Mr. Chevalier, and his gifted daughter, they had a delightful visit to beautiful Durham, and came away full of admiration for the (then newly established) University, and its grand _locale_. They went on to stay with an uncle by marriage of Yule’s, in Yorkshire. At dinner he was asked by his host to explain Foucault’s pendulum experiment. “I endeavoured to explain it somewhat, I hope, to the satisfaction of his doubts, but not at all to that of Mr. G. M., who most resolutely declined to take in _any_ elucidation, coming at last to the conclusion that he entirely differed with me as to what North meant, and that it was useless to argue until we could agree about that!” They went next to Leeds, to visit Kirkstall Abbey, “a mediæval fossil, curiously embedded among the squalid brickwork and chimney stalks of a manufacturing suburb. Having established ourselves at the hotel, we went to deliver a letter to Mr. Hope, the official assignee, a very handsome, aristocratic-looking gentleman, who seemed as much out of place at Leeds as the Abbey.” At Leeds they visited the flax mills of Messrs. Marshall, “a firm noted for the conscientious care they take of their workpeople.... We mounted on the roof of the building, which is covered with grass, and formerly was actually grazed by a few sheep, until the repeated inconvenience of their tumbling through the glass domes put a stop to this.” They next visited some tile and brickworks on land belonging to a friend. “The owner of the tile works,
