When I was a child I used to glance at the first sentence in a new book to see whether it looked interesting. If it began, "There was once a boy, who lived in a fine house," I was encouraged to go on. Now I wish to make these little books very interesting to my young readers. I want to have the words so simple that they can be read and not skipped over, and at the same time my object is to give you useful information. As you will learn, I am to tell you in these six volumes many things about building a house, and to explain the different kinds of labor or trades which are necessary for such a purpose; but first I shall introduce you to the family of Mr. Curtis, a gentleman who loves children and whom I am sure you will love before the book is finished.
