Green to Billingshurst and the Wey and Arun Junction Canal was completed in 1816 to connect to the Godalming Navigation. In 1823, the completion of the Portsmouth and Arundel Canal, including the Chichester Ship Canal, completed the London to Portsmouth route for barges and marked the end of the earl's investment in canal building. A number of vessels were named Egremont, including a barge on the Arun Navigation, a brigantine built at Littlehampton for coastal trading and wrecked on the Goodwin Sands after only two years, and later a steam tug used to tow barges across Chichester and Langstone harbours for the Portsmouth and Arundel Canal. Promoter of emigration War with France and population growth made famine an ever-present danger in the early nineteenth century and there was an urgent need to maximise food production using any land that could be cultivated. In the 1820s, emigration, mostly to Canada, was promoted as a means of relieving rural unemployment and poverty. Thomas Sockett, Rector of Petworth and Wyndham's protégé, promoted the Petworth Emigration Scheme, which sent 1,800 people from Sussex and neighbouring counties to Upper Canada between 1832 and 1837. The earl encouraged those living on his land to join the scheme by offering to pay the £10 per head cost of passage. Agriculture The Reverend Arthur Young stayed at Petworth House while conducting his surveys of English agriculture. The earl established a pedigree herd of Sussex cattle from the local breed which was commended by Young who wrote that they "must be unquestionably ranked among the best of the kingdom". A herd descended from these animals is maintained at Stag Park at the present day. Devon and Hereford cattle were also kept, together with crossbreds. Different breeds of sheep were tried and exotic Tibetan Shaul goats, which produced fine wool for hatters. Stag Park model farm was created in the northern part of Petworth Park on land cleared of scrub and gorse, consisting of between 700 and 800 acres divided into fields and drained. Land previously used for producing wood fuel could then be released for food production as wood had been replaced by coal delivered by the new canal system. Crop rotations including turnips, tares, wheat, barley, oats and grass were introduced. Potatoes were grown at Petworth and rhubarb as medicine. More unusually Young describes opium production at Petworth, with juices from the incised poppy heads being scraped into
