chewink
Eastern towhee bird, named for its call. Frost uses the local name—these birds actually do eat wild berries and would benefit from an unharvested patch.
democrat-load
A democrat wagon—light, open farm vehicle with two bench seats. The whole Loren family is piled in, a common sight in rural New England when families went berry-picking together.
