This picture is out of order it should be the last one as it shows the men grading the wool and pulling of the daggy bits.
This is the shearers working hard to get the job done. I don`t think I could bend over all day doing this job. It must be hard on your back.
The shearer in the middle is wearing a special back sling and it helps to take the pressure off your back when you have to be bent over all day. This is not a job I would like to be doing.
