From the road, Longview Farm in Walpole looks like a wealthy private school, with buildings set on 166 acres of fields and woods. Those driving by catch glimpses of an outdoor pool, a small fishing and skating pond, a garden, ropes course, and brand new playground.

But for the 56 children who live or go to school there, the newly expanded program of the Home for Little Wanderers is a place of last resort — a day and boarding school for youths with no place else to go.
