In the winter, I am persuaded, I could not exist in rooms thus closed up, with stoves heated in their manner, for they only put wood into them twice a day; and, when the stove is thoroughly heated, they shut the flue, not admitting any air to renew its elasticity, even when the rooms are crowded with company.- "Letters written during a short residence in Sweden, Norway, and Denmark", Mary Wollstonecraft.
