There was a sheepdog competition at Masterston Station. Jon and I watched a bit, and it was rather interesting. (If you've seen the movie Babe, you'll know what a sheepdog competition was like).
There was a man who communicated with his dog through a series of whistles so intricate that one certain kind of sound told the dog to take one step, another told him to go fast, yet another told him to go slow, and so on. There was a sleek sort of beauty in the dog as it raced across the field to round up the sheep, its head held low, glorying in the speed of flight.
A comical moment arose when its owner was trying to tell him, after he had rounded up the first flock, to go and get the other flock which was hidden from view. The owner kept saying "Look back!" and "lie down!", which the dog obeyed, even though it was confused--you could see the thought process going on: "But the sheep are here!" The owner hollered "What do yer think yer doin'?!", and he eventually figured out what to do.
