" Then the bull shook himself, turned his head and looked at us. There was an awed whisper from one of the young men: “By gaw, it’s working!” I enjoyed myself after that. I can’t think of anything in my working life that has given me more pleasure than standing in that pen directing the life-saving jet and watching the bull savouring it. "
