Interior of a shed where sheep are sheared. Each workman has a live sheep on the floor, and passes over its body the set of clippers worked by machinery. The wool holds together after it has been clipped. Once off, the sheep is returned to the pen, and the fleece is gathered by a boy who sets the wool in the wool-classers room.  Here men pull off burrs and dirt, and place in bins by quality.
On large stations or sheep ranches in AU, herds may number 200K sheep. They are shorn once a year and generally washed before shearing to make the wool as clean as possible.  AU, Argentina, Uraguay, Russia and the US are the leading sheep raising countries.
