During the Middle Ages and Stuart period, Great Britain had large domestic supplies of timber, especially valuable were the famous British oaks. This timber formed the backbone of many industries such as shipbuilding but not iron smelting which used charcoal derived from the wood of various trees. ==Origins== From before the industrial revolution period the price of timber in England had been increasing as domestic quantities became more difficult to obtain. Many industries thus were forced to change to substitutes. As the industrial revolution progressed coal replaced timber for use as fuel, while brick replaced timber for use in construction. It would be many decades, however, before iron could be used to replace timber in shipbuilding. By the eighteenth century England had not exhausted its supply of suitable domestic hardwood timber but – like the Netherlands – it imported softwood supplies. While every nation has trees and wood, ship timber is a far more limited product. The ideal woods were oak, Scots pine – but not spruce, and other large trees. Especially difficult to find were trees suitable to be masts, a crucial requirement for any sailing ship, and one that often had to be replaced after storms or wear. As suitable trees take decades to grow, in densely populated nations like England any given square metre of land could, usually, be far more valuably employed by producing foodstuffs rather than timber. Timber was thus only a viable industry in sparsely populated lands such as Scandinavia, those in the Baltic Sea area, and in North America. The Baltic countries, and especially Norway, had other benefits including superior sawmills, and often lower transport prices than distant overland travel. The British shipping industry, by the late seventeenth century, increasingly used imports of Baltic timber. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「British timber trade」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
