Nobody knows from what country sheep first came, but we do know that they were an important factor in the early history of man. History tells us that long, long ago they were raised for both clothing and food. The view shows part of a large flock of sheep grazing on the great plateaus of Idaho. In the foreground of the view you see the herder and his dog. One herder, with the help of a faithful dog, takes care of a great flock of sheep on these unfenced plateaus of the West.
Some flocks contain many thousands of sheep.
In this close companionship, master and dog grow to understand each other almost as keenly as though they spoke the same language. And, indeed, the dog does understand his master's words. In rounding up the scattered sheep, the dog follows his master's orders. He circles round the outer edges of the flock, and drives them more closely together. He often goes long distances and brings back to the flock a single sheep that has strayed.
