The neighbours of whom the Smiths saw most were Lord and Lady Carlisle,[74] who drove over from Castle Howard[75] in a coach-and-four with outriders, and were upset in a ploughed field; their son and daughter-in-law, Lord and Lady Georgiana Morpeth, who with their children made "no mean part of the population of Yorkshire"; and the Archbishop of York, who became one of the Smiths' kindest and most faithful friends. Every year Sydney paid a visit to London, receiving the warmest of welcomes from all his old associates. In 1821 he revisited his friends at Edinburgh, and going or coming he visited Lord Grey at Howick, Lord Tankerville at Chillingham, Lord Lauderdale at Dunbar, and Mr. Lambton, afterwards Lord Durham, at Lambton. At Chillingham he duly admired the beef supplied by the famous herd of wild cattle, but he admired still more the magnificent novelty of gas at Lambton.-- "What use of wealth so luxurious and delightful as to light your house with gas? What folly to have a diamond necklace or a Correggio, and not to light your house with gas! The splendour and glory of Lambton Hall make all other houses mean. How pitiful to submit to a farthing-candle existence, when science puts such intense gratification within your reach! Dear lady, spend all your fortune in a gas-apparatus. Better to eat dry bread by the splendour of gas, than to dine on wild beef with wax candles!" Another friend whom the Smiths visited regularly was Mr., afterwards Sir George, Philips, an opulent cotton-spinner of Manchester. Once, when staying with Philips, Sydney undertook to preach a Charity Sermon in Prestwich Church, and with reference to this he wrote in the previous week; "I desire to make three or four hundred weavers cry, which it is impossible to do since the late rise in cottons." Writing from Philips's house in 1820 he says:-- "Philips doubles his capital twice a week. We talk much of cotton, more of the fine arts, as he has lately returned from Italy, and purchased some pictures which were sent out from Piccadilly on purpose to intercept him." His daughter tells us that, during these years of small income and large expenses, her father never bought any books. He had brought a small but serviceable library with him from London, and his friends made additions to it from time to time. He wrote to a friend in 1810:-- "I have read, since I saw you, Burke's works, some books of Homer, Suetonius, a great deal of agricultural reading, Godwin's _Enquirer_, and a great deal of Adam Smith. As I have scarcely looked at a book for five years, I am rather hungry." Here are some of the plans which, year by year, he laid down for the regulation of his studies:--
