(1878)
“ In many places, and in most seasons, part of this ice lasts through the whole summer; in most places it lasts well into the summer, and even after the ice is gone the "duff" absorbs and stores away the rain, and, like a prudent housewife with her confections, gives up her treasures in such a way as not to injure the health of her children with her lavishness, nor exhaust her larder before a fresh supply can reasonably be expected. ”
