The umpire, a small boy of twelve, was lying on his stomach, squealing and tickling a collie.
There were ten of them, big tan and white collies, vying with one another to come first to their master.
One might have worked upright, with a 'loose-eye', for instance, while another might have crouched and crawled on its belly while deploying its 'collie-eye'.
For example, suppose a child is asked for ' a dog ', and is provided with two choices : a collie and a horse.
The refinement of the shepherd's use of the border collie was no doubt a part of this process.
