A cattle creep is a small, field-to-field access for farm animals, usually to allow passage beneath an obstacle such as a road, canal, or railway embankment.〔http://www.adoptafarm.com/dictionary/index.cfm?letter=C〕 Due to the primary users being cattle, or other livestock, cattle creeps usually have a low head height, making them uncomfortable for humans to use.〔http://www.leamarsh.com/creep.html〕 On Dartmoor, in south west England, the term sheep creep is used to describe a purposefully constructed gap in the base of a drystone wall commonly topped with a granite lintel. The idea was that the gap would allow sheep to pass from field to field but its size was deliberately too small for cattle or ponies to do likewise. 〔http://www.legendarydartmoor.co.uk/sheep_moor.htm〕 ==See also== *Wildlife crossing *Accommodation bridge 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「cattle creep」の詳細全文を読む スポンサード リンク
