Roofed garden seats

2250. Roofed seats of a more polished description are boarded structures, generally semi-octagonal, and placed so as to be open to the south. Sometimes they are portable, moving on wheels, so as to be placed in different positions, according to the hour of the day, or the season of the year, which, in confined spots, is a desirable circumstance. Sometimes they turn on rollers, or on a central pivot, for the same object; and this is very common in what are called barrel-seats. In general they are opaque, but occasionally their sides are glazed, to admit the sun to the interior in winter.
