CHAPTER XII. THE MULBERRY FAMILY. "There is a fruit tree," said Miss Harson, "belonging to an entirely different family, which we have not considered yet; and, although it is not a common tree with us, one specimen of it is to be found in Mrs. Bush's garden, where you have all enjoyed the fruit very much.

CHAPTER I THE SUBJECT AND THE POINT OF VIEW I submit in the following pages a proposition and a proposal—a distinction which an old-country writer of English may, perhaps, be permitted to preserve. The proposition is that, in the United States, as in other English-speaking communities, the city has been developed to the neglect of the country.
