　　Eighteenth-century houses showed great interior improvement over their predecessors. Windows were made larger and shutters removed. Large, clear panes replaced the small leaded glass of the seventeenth century. Doorways were larger and more decorative. Fireplaces became decorative features of rooms.

After about 1730, advertisements for wallpaper styles in scenic patterns began to appear in colonial newspapers. (346 words)
