A man, with three boys to his right, are walking briskly [position of their arms indicates this] on a level, graded road, bordered by low trees on each side. The man is wearing a long sleeve shirt, and the boys are all wearing short sleeve tee shirts. The shirt on the boy next to the man has horizontal stripes; the other two tees are white. The man is wearing slacks, and the two boys to his right, jeans. Starting with the man and ending with the boy on the right, their heights run uniformly down on an angle from tallest to shortest.
