The most important person among them was the "head field-driver," who held that position on account of his superior intelligence and fidelity.
The field-driver takes stray animals to the pound, and then notifies their owner; or if he does not know who is the owner he posts a description of the animals in some such place as the village store or tavern, or has it published in the nearest country newspaper.
There was once a case before him for a field-driver who had impounded cattle under the old Massachusetts law.
