Roofed seats, boat-houses, moss houses, flint houses, bark huts, and similar constructions, are different modes of forming resting-places containing seats, and sometimes other furniture or conveniences in or near them. Very neat buildings and furniture of this class may be formed of hazel-rods; or of any tree with a clean bark and straight shoots, as young oaks or mountain ash. The spruce fir affords a good outside material: and five or six young trees coupled together, make good rustic columns. At Bagshot Park, the Slopes at Windsor, and Bothwell Castle, are good examples of covered seats of the rustic kind (figs. 676, 677, 678.).
