hog-reeve (hog reefe) - an elected position in early New Hampshire townships. Settlers often let livestock graze in the woods around their fields, or on the town "common." Even if these animals were fenced, early fences were often inadequate to restrain stray animals. As a result, each town chose a hog reeve, who assumed custody of livestock that strayed into cultivated fields. Wandering livestock were called "estrays." They were "taken up," often to the "pound," where their owners could retrieve them after paying a small fine. This position was also responsible for appraising damages by stray swine, and for ordering restitution.
