There are over thirty million sheep in Britain belonging to more than sixty different breeds. They are almost as varied in shape, colour and size as the many breeds of dog but are far less well-known. The sheep industry in Britain is based on a stratified system which makes the best use of the harsh mountains of Scotland, Wales and northern England, as well as of the more fertile and mild regions of southern Britain. It has helped to develop a rich range of specialist regional breed types. This book places the breeds into intelligible groups by outlining the way the national industry works, classifying their different roles and determining where each breed fits into an overall picture. Each breed and its wool is featured, and illustrated with an extensive collection of pictures.
