A New Hampshire Historical Highway marker has been installed on Route 302 in Carroll to commemorate the 19th-century logging village of Zealand. The marker also honors Zealand’s founder, James Everell Henry. It says the village grew in 1875 to serve the logging industry and that Henry owned 10,000 acres in the heart of the White Mountains, with a 10-mile railroad to move logs from forest to sawmill. The village had a post office, school, store, housing, and charcoal kilns ‘‘to eke out every bit of forest value,’’ the marker says. The logging season employed anywhere from 80 to 250 people. By 1885, Henry left and moved on to Lincoln, leaving the Zealand area mostly clear cut. Fires destroyed the area from 1886 to 1903. Historic highway markers are at three other lumber communities — Bethlehem, Easton, and Littleton.
