 The sheep industry in Spain was an instance of migratory flock management , with large homogenous flocks ranging over the entire country . The management model used in England was quite different but had a similar importance to economy of the country . Up until the early 20th century , owling ( the smuggling of sheep or wool out of the country ) was a punishable offense , and to this day the Lord Speaker of the House of Lords sits on a cushion known as the Woolsack .
