About half of the island is agriculturally based. Oats, barley, and turnips are major crops. Fishing is important too; the Tidmouth kipper is a prized dish at breakfasts far and wide. Lead, zinc and silver are mined, and the island stone has excellent weather-resistant properties. The native language, Sudric, is dying out, but the rugged and beautiful scenery and the fishing, particularly in the mountain lakes, attract holidaymakers from all parts. Bauxite is mined at Peel Godred by the British Aluminium Company. As this process requires a huge amount of electricity, a hydroelectric power station was opened nearby in 1923. Tidmouth now contributes to the country's revenues by being an excellent port, owned by the North Western Railway. Many travelling to Douglas or Belfast embark there rather than at Liverpool or Fleetwood.
